Correct Answer: C

Rationale: The correct answer is C: 'Use a new catheter each time you perform self-catheterization.' It is essential to use a new, sterile catheter each time to prevent infection during the procedure. Choice A is incorrect because cleaning the catheter with alcohol may not be sufficient to prevent infection. Choice B is incorrect because self-catheterization is typically done in a clean, private area, not necessarily on the toilet. Choice D is incorrect because lubricating the catheter tip with petroleum jelly is a common practice but not as crucial as using a new catheter each time to prevent infection.

Correct Answer: D

Rationale: The correct action for the nurse to take in this scenario is to discontinue the oxytocin infusion. With contractions occurring every 90 seconds with a duration of 90 seconds, the contractions are too frequent and prolonged, which can lead to uterine rupture or fetal distress. Increasing or maintaining the oxytocin infusion would exacerbate the situation, potentially causing harm to the mother and fetus. Decreasing the oxytocin infusion might not be sufficient to address the issue, making discontinuation the most appropriate action to ensure the safety of both the client and the baby.

Correct Answer: A

Rationale: Providing education about the importance of medication adherence is crucial in managing hypertension. By educating the patient about the significance of taking their medication as prescribed, the healthcare provider can help improve compliance and control the patient's blood pressure. Referring the patient to a specialist (Choice B) may be necessary in some cases but addressing non-compliance should start with education. Exploring alternative treatments (Choice C) could be considered if the current medication is not suitable, but initial steps should focus on improving adherence. Reassessing the patient in 6 months (Choice D) may be too delayed if non-compliance is an issue that needs immediate attention.

Correct Answer: D

Rationale: The correct answer is D, 'Take with a glass of orange juice.' Ferrous sulfate is best absorbed with vitamin C, making orange juice the preferred choice. Choices A, B, and C are incorrect because taking ferrous sulfate with meals, at bedtime, or with milk can reduce its absorption due to interactions with food components like calcium, inhibiting the iron absorption process.

Correct Answer: C

Rationale: The correct answer is to instruct the client to sit quietly for 5 minutes before measuring their blood pressure. This allows the body to relax and stabilize, leading to a more accurate reading. Choice A is incorrect because using a cuff that is too loose can result in inaccurate readings. Choice B is incorrect as the cuff should be placed directly on the bare skin. Choice D is incorrect as using the same arm for each reading is important for consistency in monitoring, but sitting quietly before measuring is crucial for accuracy.
