Correct Answer: B

Rationale: The most important instruction for a client with tuberculosis (TB) is to take all prescribed medications as directed. This is crucial to prevent the development of drug-resistant TB. While avoiding close contact with others until treatment is complete (Choice A) is important to prevent the spread of TB, ensuring the client completes the prescribed medication regimen is the priority. Scheduling a follow-up appointment (Choice C) is important for monitoring but not as critical as medication adherence. Wearing a mask in public places (Choice D) can help reduce the spread of TB but is not as essential as taking medications as prescribed.

Correct Answer: D

Rationale: When administering medication to children, it is crucial to ensure the correct dosage to prevent dosing errors. Double-checking the dosage calculations with another nurse can help verify the accuracy of the prescribed dose, reducing the risk of medication errors. While checking the child's weight (Choice A) is important for dosage calculation, it alone may not ensure the correctness of the dosage. Verifying the medication order with a pharmacist (Choice B) is essential, but it may not directly address the accuracy of dosage calculations. Consulting the child's parents (Choice C) is not a standard practice for verifying medication dosages and should not be solely relied upon for ensuring the correct dosage.

Correct Answer: C

Rationale: The correct response is to offer the client several choices of times to bathe during the day. This approach respects the client's religious beliefs while ensuring that hygienic practices are still maintained. By providing options, the nurse can work together with the client to find a solution that aligns with both his beliefs and his health needs. Choice A is incorrect because solely reviewing the importance of hygiene may not address the client's specific religious concerns. Choice B is inappropriate as it disregards the client's beliefs and autonomy. Choice D is not the best approach as it may come off as confrontational or dismissive of the client's beliefs, rather than working collaboratively to find a suitable solution.

Correct Answer: B

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and breathing by reducing respiratory effort. Administering a high-flow oxygen mask (Choice A) may be necessary but is not the priority intervention. Providing a high-carbohydrate diet (Choice C) is not directly related to managing acute shortness of breath in COPD. Encouraging the client to cough and deep breathe (Choice D) is helpful for airway clearance but is not the priority intervention when the client is in distress with acute shortness of breath.

Correct Answer: A

Rationale: Pursed-lip breathing is a characteristic finding in clients with COPD. It helps keep the airways open during exhalation, acting as a compensatory mechanism to prevent airway collapse, which is common in COPD. Hyperresonance on percussion is typically found in conditions like emphysema, which is a component of COPD but not characteristic of the overall disease. Bradycardia is not typical in COPD; instead, clients often exhibit tachycardia due to chronic hypoxemia. High-pitched inspiratory crackles are more commonly associated with conditions like pneumonia, not COPD.
