Correct Answer: B

Rationale: The correct answer is to administer a diuretic as prescribed. In a client with chronic kidney disease experiencing increased swelling and shortness of breath, the priority action is to address fluid retention. Administering a diuretic helps reduce fluid overload, alleviate symptoms, and prevent complications associated with fluid buildup. Option A is not the priority in this situation as addressing fluid retention takes precedence over providing oxygen. While monitoring vital signs is important, it is secondary to addressing the underlying cause of symptoms. Repositioning the client may help with comfort but does not directly address the fluid overload seen in chronic kidney disease.

Correct Answer: B

Rationale: In clients with hyperthyroidism experiencing palpitations, administering a beta-blocker is the appropriate intervention. Beta-blockers help reduce heart rate and control symptoms in hyperthyroidism. Encouraging rest (Choice A) may be helpful but does not directly address the palpitations. Drinking cool fluids (Choice C) and providing a cool environment (Choice D) are more focused on temperature regulation and comfort, which are not the primary interventions for palpitations in hyperthyroidism.

Correct Answer: A

Rationale: In some cases, the smell of food cooking can trigger nausea in cancer patients. Cooking food outside reduces the intensity of odors that could trigger nausea, helping the client maintain adequate nutrition. Providing anti-nausea medication (Choice B) may not address the root cause of the nausea triggered by the smell of cooking food. Suggesting cold water (Choice C) or smaller, frequent meals (Choice D) may not directly address the issue of cooking odors triggering nausea, which is specific to this client's situation.

Correct Answer: B

Rationale: The correct answer is B: 'I should use my rescue inhaler when I start to experience wheezing.' A rescue inhaler is used during the onset of asthma symptoms, such as wheezing, to quickly open the airways. It is not intended for routine daily use or prevention, which is the role of a maintenance inhaler. Option A is incorrect because a rescue inhaler is not used for prevention but for immediate relief during an asthma attack. Option C is incorrect because the peak flow meter reading is used to monitor asthma control, not to determine when to use a rescue inhaler. Option D is incorrect because using a rescue inhaler only before going to bed does not address the need for immediate relief when wheezing or experiencing asthma symptoms.

Correct Answer: B

Rationale: When an older adult with aspiration pneumonia coughs while attempting to drink, it may indicate aspiration. Aspiration can lead to serious complications. Therefore, the appropriate intervention for the nurse in this situation is to stop feeding immediately and assess the client for signs of aspiration. Encouraging the client to drink more slowly (Choice A) may not address the risk of aspiration. Elevating the head of the bed further (Choice C) is generally beneficial to prevent aspiration but is not the priority when immediate assessment is needed. Teaching coughing and deep breathing exercises (Choice D) is not appropriate when the client is actively coughing during feeding and requires immediate assessment for potential aspiration.
