Correct Answer: B

Rationale: The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.

Correct Answer: A

Rationale: The correct action for the nurse to take is to ask the client why the bath was refused. Understanding the client's reasons for refusal can guide appropriate interventions, respecting client autonomy while addressing any underlying issues. Choice B is not the best course of action as involving family members may not address the client's specific concerns. Choice C, while important, may not directly address the immediate refusal to bathe. Choice D does not address the underlying reasons for the refusal and may not lead to a resolution.

Correct Answer: C

Rationale: The correct instruction for the nurse to provide is to shake the inhaler before each use. Shaking the inhaler ensures proper mixing of the medication before administration, which is crucial for its effectiveness. Choice A is incorrect because albuterol inhalers are often used as a preventive measure, not just during asthma attacks. Choice B is a good practice to prevent oral fungal infections associated with inhaled corticosteroids, not typically with albuterol. Choice D is important for proper inhaler technique, but the primary step before inhaling is shaking the inhaler to ensure the medication is well mixed.

Correct Answer: A

Rationale: The correct first action for a client with a cast experiencing numbness and tingling in the affected limb is to check for tightness of the cast. Numbness and tingling can indicate compromised circulation, and a tight cast may be causing this. Checking the cast for tightness is essential to ensure it is not impeding circulation. Elevating the limb, applying ice, or notifying the physician can be subsequent actions depending on the assessment findings after checking the cast. Elevating the limb might help improve circulation, applying ice is not indicated for numbness and tingling, and notifying the physician can be done if the issue persists after addressing the immediate concern of cast tightness.

Correct Answer: B

Rationale: Engaging in regular physical activity is a highly effective recommendation for lowering blood pressure and improving overall cardiovascular health. Regular exercise helps to strengthen the heart, improve blood circulation, and manage weight, all of which contribute to reducing blood pressure levels. Choices A, C, and D are incorrect. Increasing intake of red meat can lead to higher saturated fat consumption, which is detrimental to heart health. Consuming a high-sodium diet can exacerbate hypertension by increasing blood pressure. Limiting fluid intake to 1 liter per day may lead to dehydration and is not a recommended approach for managing hypertension.
