Gestational Diabetes Essay

The clinic RN reviews Amanda’s prenatal record prior to performing a nursing assessment. Amanda has given birth twice, once at 35-weeks (twins) and once at 39-weeks (singleton). All of these children are alive and well. She has had one spontaneous abortion at 9-weeks gestation. 1. How should the nurse record Amanda’s obstetrical history using the G-T-P-A-L designation? A) 3-2-0-1-3. B) 3-1-1-1-2. C) 4-1-1-1-3. D) 4-2-1-0-2. Correct answer(s): C The nurse notes that Amanda’s fasting 1 hour glucose screening level, which was done two days previously, is 158 mg/dl. 2. The nurse recognizes that what information in the client’s history supports a diagnosis of gestational diabetes? A) Maternal great-aunt has insulin dependent (Type 1) diabetes. B) Youngest child weighed 4300 grams at 39-weeks gestation. C) Trace of protein noted in urine specimen at last prenatal visit. D) Client is 64 inches tall and weighed 134 prior to pregnancy. Correct answer(s): B Further Glucose Screening Amanda is scheduled for a 3 hour oral glucose tolerance test in 5 days, and is told to arrive at the lab at 8:30 am. Amanda asks if there are any special instructions for the test in addition to fasting for 8 hours immediately prior to the test. 3. Which instruction should the nurse give the client? A) Only coffee or tea is allowed once the fasting level has been drawn. B) Follow an unrestricted diet and exercise pattern for at least 3 days before the test. C) Write down questions and call the laboratory for instructions the day before the test. D) Smoking in moderation is allowed up until the time the test begins. Correct answer(s): B Amanda asks the nurse why she wasn’t tested for gestational diabetes until she was almost 28-weeks gestation. 4. The nurse’s response should be based on the understanding of which normal physiologic change of pregnancy? A) Maternal insulin crosses the placenta to regulate fetal glucose levels throughout pregnancy. B) In the first trimester, estrogen and progesterone cause an increase in maternal fasting glucose levels. C) Hormonal changes in the second and third trimesters result in increased maternal insulin resistance. D) Fetal insulin production increases each trimester, forcing the mother’s body to produce more glucose. Correct answer(s): C Interdisciplinary Client Care Amanda’s 3 hour Oral Glucose Tolerance Test indicates that she does have gestational diabetes. The RN phones Amanda and arranges for her to meet with the CNM and perinatologist, as well as an RN diabetes educator and a registered dietician (RD) the next day. The perinatologist and CNM discuss gestational diabetes with Amanda and after seeking input from Amanda, outline their suggested plan of care, which includes dietary control and glucose self-monitoring. After the perinatologist and CNM leave, Amanda appears confused and asks the RN, â€Å"Does this mean I will always have diabetes?† 5. Which response should the nurse give to the client? A) â€Å"You will need to be periodically evaluated for Type 2 diabetes for the rest of your life.† B) â€Å"There should be no problem as long as you do not have to use insulin during this pregnancy.† C) â€Å"There is no need to talk about this now. We’ll discuss it at your first postpartum visit.† D) â€Å"Tell me what worries you about the possibility of developing Type 2 diabetes after your pregnancy ends.† Correct answer(s): A After all her questions are answered, Amanda is scheduled for a return visit with the CNM in one week, and is escorted to the office of the registered dietician (RD). The RD discusses the need to control carbohydrates while maintaining an appropriate carbohydrate-protein-fat ratio to promote consistent weight gain (based on the woman’s body mass index), prevent ketoacidosis, and encourage normoglycemia (euglycemia). Amanda is then introduced to the RN diabetes educator. She asks the nurse to clarify what the RD told her about the content and timing of her meals. 6. Which response should the nurse give to the client? A) Eliminate the bedtime snack if heartburn develops after eating. B) Choose complex carbohydrates that are high in fiber content. C) Increase the percentage of protein in the diet if anemia develops. D) Vary timing of meals and snacks based on individual preferences. Correct answer(s): B The RN diabetes educator makes a plan of care to teach Amanda to monitor her glucose levels. The RN diabetes educator discusses the use of self-glucose monitoring and gives Amanda verbal and written guidance about optimal glucose levels at each glucose testing point throughout the day. The nurse also provides instruction about calibration of the glucose monitor, fingerstick technique, and use of the monitor for testing. After reviewing the instructions and a successful return demonstration, the diabetes educator and Amanda agree to meet after Amanda’s prenatal appointment to follow-up on today’s teaching/learning. 7. Which fingerstick blood glucose (FSBG) testing protocol should the diabetes educator recommend for Amanda? A) Only if symptoms of hypoglycemia or hyperglycemia occur. B) Prior to breakfast (fasting) and two hours after each meal. C) Before and two hours after all meals, at bedtime, and during the night. D) Once daily until glucose levels are stabilized, then weekly. Correct answer(s): B A Complication Occurs Amanda manages her gestational diabetes with diet. She experiences a few episodes of postprandial hyperglycemia, but does not have to go on insulin. At her 36-week prenatal visit, the CNM assesses Amanda and finds that there is no increase in fetal growth since the week before. When questioned further, Amanda tells the CNM that the infant has seemed to â€Å"slow down† a little the last few days. After consultation with the perinatologist, a biophysical profile (BPP) is scheduled and Amanda is admitted to the hospital’s antepartum unit. The antepartum RN performs a nonstress test (NST) as part of the BPP. 8. The nurse recognizes which fetal heart rate (FHR) changes indicate a reactive nonstress test? A) Persistent late decelerations associated with three uterine contractions, lasting 40 to 60 seconds each in a 10 minute period. B) An increase in the FHR baseline to 170 beats per minute, lasting for at least 20 minutes. C) Marked, long term FHR variability in response to contractions caused by nipple stimulation. D) Two episodes of acceleration (> 15 beats/minute, lasting > 15 seconds) related to fetal movement in a 20 minute period. Correct answer(s): D Amanda has a non-reactive Non-stress Test. She is taken to the ultrasound department for completion of the BPP and her total score is 6 (Fetal Breathing Movements = 2, Gross Body Movements = 0, Fetal Tone = 2, Reactive Non-stress Test = 0, and Qualitative Amniotic Fluid Volume = 2). Based on this score, the perinatologist recommends an amniocentesis be completed to assess for lung maturity prior to making a decision whether to induce delivery for Amanda the next day. 9. Prior to the amniocentesis, which action should the nurse take first? A) Administer Rh immune globulin (RhoGAM) if client is Rh negative. B) Assist the client to the bathroom and ask her to empty her bladder. C) Apply the external fetal monitor to evaluate uterine contractility. D) Clean the abdomen with betadine solution and sterile 4 by 4s. Correct answer(s): B Amanda and her fetus are monitored for two hours after the procedure and display no adverse effects so the external fetal monitor is discontinued. The amniocentesis reveals fetal lung maturity and an induction is scheduled for the next morning. At 2 a.m. Amanda complains of increased uterine discomfort. She is contracting every 10 minutes and while the antepartum nurse is in the room, Amanda’s membranes rupture spontaneously. 10. Which action by the nurse takes priority? A) Notify the CNM and perinatologist of the changes in Amanda’s status. B) Transfer Amanda to the labor-delivery-recovery (LDR) suites. C) Reapply the external fetal monitor to evaluate the fetal heart rate. D) Start an intravenous line using an 18 gauge or larger intravenous catheter. Correct answer(s): C

Establishing Effective Working Relationships Essay

Establishing Effective Working Relationships - Essay Example These are orienting the learner to the practice setting, encouraging the patient acceptance of the learner and the role of the practice as a teaching facility, adapting the patient schedule while working with the learner, keeping the flow going, and finding some time to teach the students. The efficient and effective orientation includes the establishment of a system that can orient learners to help assure the teacher that he or she will be able to cover all the relevant points with each learner. Some preceptors tend to use the checklist in reminding the learners of the topics that are to be covered while clarifying his or her expectation. If learners are made to be available throughout, it can help save time in writing out procedures, policies, expectations and responding to questions after the learner reviews the handout. Letting learners note their past experiences reviewed in previous meetings can also be an effective step in assessing the levels and skills of the students. As an orientation process, the development of 5-8 rotation objectives that can be achieved with the learners can help in focusing the process of teaching during the rotation process. Preceptors that adopt the process to write the rotation objectives down and make sure they are hanging in the clinical area to create awareness to other staff of the interest of the learner. Encouraging other staff to take part in the orientation process lightens the workload and helps the staff to feel that they have invested in the education of the learner.

Case study analysis Essay Example | Topics and Well Written Essays - 1000 words - 6

Case study analysis - Essay Example Many foreign business people were encouraged to invest in Russia and a privatisation programme was introduced, as well. The economic reform policy led to high inflation rates in 1992 and the succeeding eight years. The national output fell by almost 20 per cent in 1992 leading to increased unemployment rate in the same year. There was a huge government deficit in 1992 rising from 1.5 per cent in the first quarter to 15 per cent in the last quarter. The economic growth rate slowed down in 1993 until 2000 where the economy almost realised full recovery. Inflation may refer to the general increase in prices of commodities in an economy. Following the introduction of the reform policy in 1991, Russian economy experienced a hyperinflation in 1992, which amounted to 1527 per cent. The reform critics argued that the Russian economy was very rigid to adopt the mixed economy system. They added that the increased rate of money supply of 600 per cent contributed to the increased inflation rates. When the government abolished the price controls, the monopoly producers hiked the prices of their products. The consumers, on the other hand, could not afford the goods sold at high prices and this lead to a huge decline in demand. The forces of foreign investors lead to some local producers escape the industry and, as a result, there were huge shortages of commodities in the market. Consequently, the decreased supply levels led to increased prices of commodities, such as food and clothing (Leitzel 213). The rate of inflation rose from less than 200 per cent in 1991 to more than 1400 per cent in 1992. In 1993, the inflation rate fall drastically to around 300 per cent and reduced gradually to a value below 10 per cent in 1997. Despite the financial crisis in 1998, the rate of inflation remained constant until 199 when it rose with a small per cent. Since 2000, the rate of inflation has remained below 15 per cent until 2008 (see the blue curve). The real GDP declined

Recruitment and retention plan for entry level officers Research Paper

Recruitment and retention plan for entry level officers - Research Paper Example Recruitment means evaluating the psychological profile, mental ability and physical conditioning of a candidate. Once an applicant is selected, they undergo training and further evaluation to assure the capacity to perform up to rigorous standards of duty. Important to the process is a retention element. Keeping good employees saves the effort to find new ones.

Thus, a successful recruitment plan must overcome any recruit’s perceived career limitations with the following incentives: a purposeful job, a stimulating set of responsibilities, a collegial working environment, reasonable pay and benefits, opportunities for care er advancement, and job security. (Bailey, 1995, p. 513) The key to a successful recruitment plan is to attract the most qualified candidates.

Augustus from Prima Porta Essay Example | Topics and Well Written Essays - 500 words

Augustus from Prima Porta - Essay Example "The posture is that of a victorious general addressing his troops, and the emperor is shown in armor. His breastplate is sculpted with scenes of Roman military triumph and the mythological figures of gods and goddesses. The pose of the figure is clearly based on the Greek model of the Spear Carrier, and the face shown is that of a handsome man in the prime of life." (Lewis and Lewis, 230) Through an effective combination of Greek idealization and Roman realism, this marble statue creates a convincing portrait of a 'real man' and a successful image of the perfect leader. Augustus is represented in this statue as the 'pater patriae', who is looking down on his people with calm concern and complete self confidence. Therefore, it is essential to realize that Augustus of Prima Porta, which is now displayed in the Braccio Nuovo of the Vatican Museums, is a perfect example of the Imperial Roman statuary and Augustus, in this statue, consciously attempts to identify himself with the ultimat e authority of Rome during the Golden Age of the Roman civilization. In a reflective analysis of Augustus of Prima Porta, it becomes lucid that this statue of the emperor Augustus can rightly be considered one of the most essential examples of the enigmatic works of art from the Augustan era.

Economic Development and Corruption Essay Example | Topics and Well Written Essays - 1500 words

Economic Development and Corruption - Essay Example In a developing economy there is improvement in the standard of living of people and focus on environmental stability also increases. Economic stability can sometime also give rise to materialism. People strive hard to make more money and they often use unethical means to achieve their materialistic targets. One such unethical method is corruption. Different people hold different views about the impact of corruption on the economic development. Many people view it as a barrier to economic development while others believe that it does not impact the society and economic development much (Easterly 2006). This paper is going to discuss various anecdotal evidence and view that people have about corruption in relation to economic development. Economies in the transition face often have large number of lobbying efforts going on. These economies are aiming for economic development and hence they do not care much about lobbying efforts and governments of these economies are more susceptible to lobbying pressures than a government of a more developed nation. The evidence and research shows that these lobbies often pay huge sum of money to the government pressures to accept their demand. The corrupt political system in these countries makes it possible for people to form lobbies and put pressure on political leaders. These leaders often get directions from these lobbies if they pay them well. Since many lobbying groups are fighting for what is good for their own business, they end up doing well for the society also. The theory of invisible hand comes into play here. The theory states that any action done for one’s own self motive or profit will eventually translate into good for the society. Hence, corruption in all cases is not bad and research on 4000 firms in developing countries shows that corruption has played a role in the economic development of a nation. (Campos & Giovannoni 2007) In another paper, it was argued that corruption is essentially bad for a gro wing economy. First of all, corruption reduces the value of shareholders. In growing economies where corruption is extremely high, the expected profit that the shareholders expect to make does not materialize. Much of the profit is lost in the corrupt red-lines of bureaucracy and hence shareholder value goes down in the corrupt economies. Many foreign companies therefore try not to invest in corrupt nations fearing that returns on investment in these economies would be far less than if the investment is made in the local setting. This reduces foreign direct investment flows into the corrupt economies and poses a big problem for the economic development. This argument shows us that corruption can be a big barrier in the economic development of a nation. (Weitzel & Berns 2006) In a recent paper written by a well known economist, it was argued that corruption is actually good for the economies. It increases the flow of wealth in the economy from one hand to another and promotes economi c activity which leads to economic development. It was argued that corruption becomes bad when the corruption money goes out from the system. Evidence shows that many political and rich figures in the developing economies put their money in bank accounts in the foreign countries. This is an example of money flowing out of the system and this money does not promote any

Diagnosis Related Groups Essay Example | Topics and Well Written Essays - 750 words

Diagnosis Related Groups - Essay Example A patient is assigned this category of DRG when all the operating room procedures performed on this patient are unrelated to the major diagnostic category of the patient's principal diagnosis. DRG 468 thus pays for discharge in which the patient undergoes an operating room procedure entirely unrelated to this admission's principal diagnosis. This is against the PPS classification of discharges of clinically coherent groups. Although this is possible in some cases, DRG 468 can be an example of DRG creep. The attending physician may misspecify the principal diagnosis, secondary diagnosis, or the procedure on the attestation sheet. It can also be the result of miscoding, where the hospital assigns an incorrect numeric code to the diseases or procedures which had been correctly attested by the physician in charge. In some cases to avoid investigation, the hospital may substitute a secondary diagnosis for the correct principal diagnosis. Therefore for appropriation of facts, auditing and review is necessary that would identify discharges in which coding rules are either ignored or not applied appropriately. DRG 468 is assigned when all the operating room procedures are unrelated to the major diagnostic category for which the patient had been admitted. Most often, these patients are admitted with a principal diagnosis that does not need any surgery. ... To assess the appropriateness, the ICD-9-CM coding guidelines should be applied to do the initial coding and for auditing if such has been used. The principal diagnosis is always the reason for admission, which should be backed by records indicating circumstances at admission, diagnostic workup, and therapy provided. The scenario is not an admission of the patient to treat two conditions, it is rather two conditions present during admission. While auditing and reviewing, it is to be determined whether the principal diagnosis was the reason for admission and treatment. If at admission, there were more than one diagnoses, use of guidelines for selecting the principal diagnosis would be used with consideration of circumstances at admission, diagnosis workup, and the therapy provided. The principal procedure must be performed for definitive treatment, not for diagnostic purposes, exploratory purposes, or for a complication. If there are two procedures done, then the one most related to t he principal diagnosis would be selected as the principal procedure. The procedure must be significant as defined by the Uniform Hospital Discharge Data Set would be used, and for this to qualify, it must be surgical under anesthesia with the operator being specially trained. The audit must look at the detailed documentation in the medical record. There must be enough proof and substantiation that it was medically necessary. The coding should be done from the narrative description of the procedure, not from the written title of the procedure. The approach and closure of the procedure are integral part of one significant procedure, not two separate
