Correct Answer: B

Rationale: In the scenario described, the presence of late decelerations during contractions indicates fetal compromise. To address this, the nurse's initial action should be to turn off the oxytocin (Pitocin) infusion. Oxytocin can contribute to uteroplacental insufficiency, leading to late decelerations. This intervention aims to improve fetal oxygenation and prevent further stress on the fetus. Immediate cesarean birth is not the first-line action unless other interventions fail. Notifying the anesthesiologist about disconnecting the epidural infusion is not the priority in this situation. Applying an internal fetal monitoring device is invasive and not the immediate step needed when late decelerations are present.

Correct Answer: A

Rationale: The correct answer is A: 'It helps my body make red blood cells.' Erythropoietin is a medication that stimulates the production of red blood cells in the body. Clients with chronic renal failure often develop anemia due to decreased erythropoietin production by the kidneys. This medication helps address that issue by increasing red blood cell production. Choices B, C, and D are incorrect because erythropoietin does not prevent infections, help kidneys excrete excess fluid, or assist with breathing; its primary action is to boost red blood cell production.

Correct Answer: C

Rationale: Centralized cyanosis and tachycardia are classic signs of congenital heart disease. Choice A is incorrect because cyanosis in the hands and feet is not specific to congenital heart disease. Choice B is incorrect as the vital signs provided are not specific indicators of congenital heart disease. Choice D is unrelated to the typical signs of congenital heart disease.

Correct Answer: A

Rationale: In a client with chronic renal failure, difficulty breathing is the most critical finding to report. This symptom may indicate fluid overload or pulmonary edema, which can be life-threatening. Shortness of breath when lying flat (orthopnea) is also concerning but less urgent than difficulty breathing. Swelling in the feet and ankles (edema) is a common finding in renal failure but may not be as immediately critical as difficulty breathing. A metallic taste in the mouth is associated with uremia, a common complication of chronic renal failure, but it is not as urgent as respiratory distress.

Correct Answer: B

Rationale: The correct action for the nurse to implement first is to elevate the head of the bed. Elevating the head of the bed helps prevent aspiration in clients with swallowing difficulties by reducing the risk of food or fluids entering the airway. While obtaining a speech therapy consult (Choice A) is important, the immediate priority is to ensure the client's safety by positioning them properly. Checking the client's lung sounds (Choice C) and implementing aspiration precautions (Choice D) are also essential steps but should follow the immediate intervention of elevating the head of the bed to prevent aspiration.
