Correct Answer: C

Rationale: The correct action the nurse should take when administering potassium chloride IV to a client with hypokalemia is to infuse the medication at a rate of 10 mEq/hr. This slow infusion rate is crucial to prevent the development of hyperkalemia, a potentially dangerous condition. Option A is incorrect because giving the medication as a bolus over 10 minutes can lead to adverse effects. Option B is incorrect as potassium chloride does not necessarily need to be diluted before administration in this scenario. Option D is incorrect as administering the medication undiluted can also increase the risk of hyperkalemia.

Correct Answer: C

Rationale: The correct answer is C: 'Ensure that the client has a referral for physical therapy.' For a client with left-sided hemiplegia, physical therapy is crucial in restoring function and mobility. It is the nurse's priority to ensure the client receives the necessary rehabilitation services. Consulting with a case manager about insurance coverage (Choice A) is important but not the priority at this stage. Counseling caregivers on respite care options (Choice B) and referring the client to a local stroke support group (Choice D) are also valuable but not as essential as ensuring the client has access to physical therapy for rehabilitation.

Correct Answer: D

Rationale: The correct answer is D. A weight gain of 1.5 kg (3.3 lb) in 24 hours can indicate fluid retention and worsening heart failure in clients taking digoxin. This rapid weight gain could be due to fluid accumulation, a common sign of heart failure exacerbation. Reporting this finding to the provider is crucial for prompt intervention. Choices A, B, and C are within normal ranges and not directly indicative of worsening heart failure in this context, making them less urgent to report compared to the significant weight gain.

Correct Answer: D

Rationale: The correct answer is D. Using pursed-lip breathing techniques is beneficial for clients with COPD as it helps control shortness of breath by keeping airways open longer. Option A is incorrect as deep breathing while using an incentive spirometer is essential to prevent complications such as atelectasis. Option B is incorrect because limiting fluid intake to 1 liter per day is not a standard recommendation for clients with COPD. Option C is incorrect as exercising in a humid area can exacerbate breathing difficulties for clients with COPD.

Correct Answer: C

Rationale: The correct action to reduce the risk of aspiration in clients receiving enteral feedings is to elevate the head of the bed during feedings. This position helps prevent regurgitation and aspiration of the feeding. Positioning the client supine (Choice A) increases the risk of aspiration as it promotes reflux. Administering feedings over 10 minutes (Choice B) does not directly reduce the risk of aspiration. Placing the client in a lateral position after feedings (Choice D) does not address the risk of aspiration during the feeding process.
