Nursing Elites

1. Polygenic traits are those that are:

• A. developed during adolescence.
• B. transmitted by the mother.
• C. uncommon in humans.
• D. determined by several pairs of genes.

Correct answer: D

Rationale: Polygenic traits, such as height and skin color, are determined by several pairs of genes working together. These traits are influenced by the combined effects of multiple genes across the genome, rather than being controlled by a single gene pair. Choices A, B, and C are incorrect because polygenic traits are not specifically developed during adolescence, transmitted by the mother, or uncommon in humans. Understanding polygenic traits is essential in genetics as they demonstrate the complexity of genetic inheritance and the influence of multiple genes on a single trait.

2. A primiparous woman presents in labor with the following labs: hemoglobin 10.9 g/dL, hematocrit 29%, hepatitis surface antigen positive, Group B Streptococcus positive, and rubella non-immune. Which intervention should the nurse implement?

• A. Transfuse 2 units of packed red blood cells.
• B. Give measles, mumps, rubella vaccine 0.5 mL.
• C. Administer ampicillin 2 grams intravenously.
• D. Inject hepatitis B immune globulin 0.5 milliliters.

Correct answer: C

Rationale: The correct intervention in this scenario is to administer ampicillin 2 grams intravenously. This is crucial to prevent Group B Streptococcus infection in the newborn during delivery. Option A, transfusing packed red blood cells, is not indicated based on the hemoglobin and hematocrit levels provided. Option B, giving measles, mumps, rubella vaccine, is not necessary at this time. Option D, injecting hepatitis B immune globulin, is not appropriate for the conditions presented in the question.

3. A woman with gestational diabetes has had little or no experience reading and interpreting glucose levels. The client shows the nurse her readings for the past few days. Which reading signals the nurse that the client may require an adjustment of insulin or carbohydrates?

• A. 75 mg/dl before lunch. This is low; better eat now.
• B. 115 mg/dl 1 hour after lunch. This is a little high; maybe eat a little less next time.
• C. 115 mg/dl 2 hours after lunch. This is too high; it is time for insulin.
• D. 50 mg/dl just after waking up from a nap. This is too low; maybe eat a snack before going to sleep.

Correct answer: D

Rationale: 50 mg/dl after waking from a nap is too low. During hours of sleep, glucose levels should not be less than 60 mg/dl. Snacks before sleeping can be helpful. The premeal acceptable range is 60 to 99 mg/dl. The readings 1 hour after a meal should be less than 129 mg/dl. Two hours after eating, the readings should be less than 120 mg/dl.

4. A newborn assessment reveals spina bifida occulta. Which maternal factor should the nurse identify as having the greatest impact on the development of this newborn complication?

• A. Tobacco use.
• B. Folic acid deficiency.
• C. Short interval between pregnancies.
• D. Preeclampsia.

Correct answer: B

Rationale: Folic acid deficiency during pregnancy is strongly associated with neural tube defects like spina bifida occulta. Adequate folic acid intake before and during early pregnancy significantly reduces the risk of such complications. Tobacco use (Choice A) is linked to other adverse outcomes but not specifically spina bifida occulta. Short intervals between pregnancies (Choice C) can increase the risk of preterm birth and low birth weight but are not directly linked to spina bifida occulta. Preeclampsia (Choice D) is a hypertensive disorder that poses risks to both the mother and baby but is not the primary factor contributing to spina bifida occulta development.

5. What additional assessment is required for the postoperative care of a pregnant woman who undergoes abdominal surgery for appendicitis?

• A. Intake and output (I&O) and intravenous (IV) site.
• B. Signs and symptoms of infection.
• C. Vital signs and incision.
• D. Fetal heart rate (FHR) and uterine activity.

Correct answer: D

Rationale: The correct additional assessment for postoperative care of a pregnant woman requiring abdominal surgery for appendicitis is monitoring the fetal heart rate (FHR) and uterine activity. This is crucial due to the presence of the fetus. Continuous fetal and uterine monitoring should be prioritized to ensure the well-being of both the mother and the baby. While assessing I&O levels and the IV site are common postoperative care procedures, they are not specific to the unique needs of a pregnant woman. Evaluating for signs and symptoms of infection is important for any postoperative patient but is not the additional assessment required specifically for a pregnant woman in this scenario. Routine vital signs and incision evaluation are standard components of postoperative care but do not address the specific needs related to the fetus and the uterus in this case.
