1. Why is a low-protein diet recommended for a patient with renal failure?
- A. To prevent fluid overload
- B. To reduce nitrogenous waste
- C. To maintain electrolyte balance
- D. To prevent hyperglycemia
Correct answer: B
Rationale: A low-protein diet is crucial for patients with renal failure to reduce the generation of nitrogenous waste products like urea and creatinine, which the compromised kidneys struggle to eliminate effectively. By limiting protein intake, the production of these waste products is decreased, lessening the burden on the kidneys and helping to manage the progression of renal failure. Choices A, C, and D are incorrect because a low-protein diet primarily aims to reduce the workload on the kidneys by decreasing the production of nitrogenous waste, not to prevent fluid overload, maintain electrolyte balance, or prevent hyperglycemia.
2. A primipara at 38-weeks gestation is admitted to labor and delivery for a biophysical profile (BPP). The nurse should prepare the client for what procedures?
- A. Chorionic villus sampling under ultrasound.
- B. Amniocentesis and fetal monitoring.
- C. Ultrasonography and nonstress test.
- D. Oxytocin challenge test and fetal heart rate monitoring.
Correct answer: C
Rationale: A biophysical profile (BPP) is a prenatal test that assesses the well-being of the fetus. It typically includes ultrasonography to evaluate fetal movements, muscle tone, breathing movements, and amniotic fluid volume. Additionally, a nonstress test is performed to monitor the fetal heart rate in response to its movements. These tests help in determining the overall health and viability of the fetus, making them essential components of prenatal care for assessing fetal well-being.
3. A nurse is reviewing a laboratory report for a client who is at 33 weeks of gestation and has preeclampsia. Which of the following laboratory results should the nurse report to the provider?
- A. BUN 35 mg/dL
- B. Hgb 15 g/dL
- C. Bilirubin 0.6 mg/dL
- D. Hct 37%
Correct answer: A
Rationale: A BUN of 35 mg/dL indicates potential kidney impairment, which is a concern in preeclampsia due to compromised renal function. This finding warrants further evaluation by the provider. High BUN levels may suggest reduced kidney function, a common complication associated with preeclampsia. Hgb, Bilirubin, and Hct levels are within normal ranges and are not directly indicative of kidney impairment or preeclampsia in this scenario. Therefore, the nurse should report the elevated BUN level to the healthcare provider for prompt management and monitoring.
4. A nurse is preparing to administer enoxaparin to a client. Which of the following actions should the nurse take?
- A. Aspirate before injecting
- B. Massage the site after injecting
- C. Administer the injection in the abdomen
- D. Inject at a 90-degree angle
Correct answer: C
Rationale: The correct action the nurse should take when administering enoxaparin is to inject the medication in the abdomen subcutaneously. This route ensures proper absorption of the medication. Aspiration is not necessary before injecting enoxaparin as it is a subcutaneous injection, not an intramuscular injection. Massaging the site after injecting should be avoided to prevent bruising. Enoxaparin injections are typically given at a 45 to 90-degree angle, not necessarily at a strict 90-degree angle.
5. A nurse is assessing a 2-hour-old newborn for cold stress. Which of the following findings should the nurse expect?
- A. Respiratory rate of 60/min
- B. Jitteriness of the hands
- C. Diaphoresis
- D. Bounding peripheral pulses
Correct answer: B
Rationale: The correct answer is B: Jitteriness of the hands. Jitteriness is a key sign of cold stress in a newborn, indicating the need for immediate warming measures. A respiratory rate of 60/min may not be directly indicative of cold stress. Diaphoresis (excessive sweating) and bounding peripheral pulses are not typical findings associated with cold stress in newborns.
