Correct Answer: C

Rationale: The correct answer is C: 'Hypokalemia.' Thiazide diuretics commonly cause potassium loss, which can lead to hypokalemia. Monitoring potassium levels is essential when a client is taking thiazide diuretics to prevent complications such as cardiac dysrhythmias. Choices A, B, and D are incorrect. Hyperkalemia (choice A) is an elevated level of potassium, which is not typically associated with thiazide diuretics. Hypernatremia (choice B) is an elevated level of sodium, and hypoglycemia (choice D) is low blood sugar, neither of which are directly linked to thiazide diuretic use.

Correct Answer: D

Rationale: Assessing the client's lung sounds is the most appropriate initial action when a postoperative client complains of sudden shortness of breath. This step helps the nurse evaluate the respiratory status and detect abnormalities such as decreased breath sounds or crackles, which could indicate a serious condition like a pulmonary embolism. Administering oxygen (Choice A) may be necessary but should come after assessing the lung sounds to ensure the appropriate intervention. Calling the healthcare provider (Choice B) or preparing for a chest x-ray (Choice C) can be important subsequent actions based on the findings from the lung sound assessment, but they are not the first priority in this situation.

Correct Answer: B

Rationale: During a manic episode, individuals with bipolar disorder may experience sensory overload and agitation. Providing a structured environment with minimal stimulation is the most appropriate initial intervention as it can help reduce overwhelming sensory input and promote a sense of calm. Engaging the client in a quiet activity (Choice A) may not be effective if the environment is still overstimulating. Continuous monitoring (Choice C) is important but may not be the first intervention needed. Adjusting lighting and noise levels (Choice D) can be helpful but may not address the core issue of sensory overload and agitation during a manic episode.

Correct Answer: D

Rationale: A comprehensive care plan for a client with depression should include multiple components to address various aspects of health. Regular physical activity can help improve mood and overall well-being. Scheduled sleep patterns are essential as sleep disturbances are common in depression and can worsen symptoms. Social interaction with family and friends provides emotional support and reduces feelings of isolation. Therefore, including all these aspects in the care plan can help support the client's recovery. Choice D, 'All of the above,' is the correct answer because all the options are important components of a holistic care plan for depression. Choices A, B, and C are incorrect because each of these elements plays a crucial role in managing depression.

Correct Answer: C

Rationale: The correct intervention for a client experiencing difficulty expectorating thick secretions due to pneumonia is to encourage increased fluid intake. Increasing fluid intake helps to thin secretions, making them easier to expectorate. Administering antibiotics (Choice A) is important in treating pneumonia but does not directly address the issue of thick secretions. Chest physiotherapy (Choice B) may help in some cases, but increasing fluid intake is a more straightforward and effective intervention. Providing humidified oxygen (Choice D) can help with oxygenation but does not directly address the problem of thick secretions.
