Correct Answer: A

Rationale: The correct answer is A. Using crutches indicates an understanding of weight-bearing restrictions post-surgery. Choice B is incorrect because waiting for a wheelchair is not related to postoperative mobility instructions. Choice C is incorrect as turning in bed using the trapeze bar and side rails does not address weight-bearing restrictions. Choice D is incorrect because putting full weight on the foot immediately after surgery contradicts the need to keep weight off the knee.

Correct Answer: C

Rationale: The correct answer is C, complaints of shortness of breath on exertion. This symptom is indicative of heart failure, a common cardiac complication of arterial hypertension. Shortness of breath on exertion is often due to the heart's inability to pump effectively, leading to fluid buildup in the lungs. Choices A, B, and D are incorrect because complaints of an occipital headache, a palpable dorsal pedis pulse bilaterally, and a blood pressure of 160/90 do not specifically indicate a cardiac complication in a client with arterial hypertension.

Correct Answer: B

Rationale: In this situation, the nurse should prioritize the safety of the client. Taking the client to a room for supervision by staff is crucial to ensure immediate safety and further assessment of the client's condition. While cleaning and assessing the client's wrists are important, ensuring ongoing safety and monitoring by staff is the priority. Calling the healthcare provider at this moment may cause delays in providing immediate assistance. Finding supplies to put a dressing on the client's wrists can wait until the client is in a safe environment. Therefore, option B is the best course of action to address the client's safety needs promptly.

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: C

Rationale: The correct action for the nurse to take when a client on ciprofloxacin reports loss of appetite and a metallic taste in the mouth is to notify the healthcare provider of the client's symptoms. These symptoms could indicate a need for a change in medication or additional treatment, which the healthcare provider would need to assess. Instructing the client to take ciprofloxacin with food (choice B) may help with gastrointestinal upset but will not address the reported symptoms. Reassuring the client (choice A) is important for providing emotional support but does not address the need for further evaluation. Encouraging increased fluid intake (choice D) is generally beneficial but may not directly address the specific side effects reported.
