Correct Answer: A

Rationale: The most crucial action for the nurse before administering a stat dose of potassium chloride IV to a client with hypokalemia is to ensure the IV is flowing freely. A freely flowing IV is essential to safely and effectively deliver potassium chloride, helping to prevent infusion-related issues. Checking the client's electrolyte levels or obtaining a baseline ECG may be important but are not the most critical actions before administering the medication. Mixing the medication thoroughly is not applicable in this scenario as potassium chloride is typically provided ready to use.

Correct Answer: D

Rationale: When dealing with a newly admitted elderly client with dementia who is resistant to care, it is crucial to employ multiple strategies to facilitate cooperation. Using short, simple sentences and maintaining a calm demeanor can help the client better understand instructions and reduce agitation. Involving family members can provide comfort and reassurance to the client, potentially decreasing resistance. Offering choices allows the client to feel a sense of control and autonomy in their care, which can increase cooperation and reduce challenging behaviors. Therefore, a combination of clear communication, family involvement, and providing choices is essential to effectively engage and care for a client with dementia. Choices A, B, and C all play crucial roles in addressing the needs of the client, making 'All of the above' the correct answer.

Correct Answer: C

Rationale: In this scenario, the correct intervention is to outline the area with ink and check it every 15 minutes to monitor for changes in bleeding. This approach helps in assessing the extent and progression of the bleeding. Option A is incorrect because assessing hemoglobin levels would not provide immediate information on the ongoing bleeding. Option B is premature without first monitoring the bleeding site. Option D is incorrect because although some postoperative bleeding can be expected, fresh bleeding on the cast warrants immediate monitoring and evaluation.

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.

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.
