Correct Answer: B

Rationale: The correct answer is B: Vision changes. Vision changes are a classic sign of digoxin toxicity and should be reported immediately to the provider for further evaluation and management. A heart rate of 78/min, a respiratory rate of 16/min, and a blood pressure of 120/80 mm Hg are within normal ranges and are not typically associated with digoxin toxicity. Therefore, they would not be the priority findings to report in this situation.

Correct Answer: C

Rationale: In this scenario, the FHR baseline of 100/min for the past 15 minutes indicates fetal bradycardia, which can be caused by maternal hypoglycemia. Maternal hypoglycemia can lead to decreased oxygen supply to the fetus, resulting in fetal bradycardia. Maternal fever (Choice A) typically presents with tachycardia in the fetus rather than bradycardia. Fetal anemia (Choice B) is more likely to manifest as tachycardia due to compensation for decreased oxygen delivery. Chorioamnionitis (Choice D) may lead to fetal tachycardia as a sign of fetal distress, not bradycardia.

Correct Answer: A

Rationale: When a client with a history of depression is experiencing a situational crisis, the first action the nurse should take is to notify the client's support system. This is crucial as the client may require immediate assistance and support. While helping the client identify personal strengths and confirming the client's perception of the event are important aspects of the assessment and intervention process, notifying the support system takes priority in ensuring the client's safety and well-being. Teaching relaxation techniques may be beneficial but addressing the client's immediate crisis through support system notification is the most appropriate initial action.

Correct Answer: C

Rationale: The correct answer is C. The charge nurse should include information that the proxy can make treatment decisions if the client is under anesthesia. This is a key function of a durable power of attorney for health care. Choices A, B, and D are incorrect because a health care proxy's role is specifically related to making health care decisions, not financial decisions, legal issues, or decisions made under anesthesia.

Correct Answer: C

Rationale: Corrected Rationale: Spironolactone is a potassium-sparing diuretic, so serum potassium should be monitored to evaluate its effectiveness. Monitoring serum potassium levels is crucial because spironolactone can cause hyperkalemia as a side effect. Serum sodium, serum calcium, and serum glucose levels are not directly affected by spironolactone and would not provide an accurate assessment of the medication's effectiveness.
