Correct Answer: A

Rationale: The correct intervention for the nurse to implement in this scenario is to determine the client's sleep and activity pattern. By assessing the client's patterns, the nurse can identify factors contributing to the sleep issues and tailor appropriate interventions. Choice B is incorrect because prescribing medication without a comprehensive assessment is not the initial step. Choice C is unnecessary at this stage as the client's symptoms are likely related to stress rather than a neurological disorder. Choice D, while important, should come after understanding the client's sleep patterns to provide holistic care. Therefore, option A is the best choice to address the client's sleep difficulties and headaches effectively.

Correct Answer: D

Rationale: Altered mental status would be the most concerning symptom in a client with liver cirrhosis. It may indicate hepatic encephalopathy, a serious complication requiring immediate intervention. While jaundice, ascites, and hepatomegaly are common in liver cirrhosis, they do not directly correlate with the urgency and severity of hepatic encephalopathy as altered mental status does. Therefore, altered mental status takes priority for immediate attention and intervention.

Correct Answer: D

Rationale: The most important intervention for the LPN/LVN to implement for a male client experiencing urinary retention is to assess for bladder distention. This assessment is crucial as it helps identify the underlying cause of urinary retention, such as bladder distention or obstruction. By assessing the bladder, the LPN/LVN can determine the appropriate interventions needed, such as catheterization, medication administration, or further evaluation by the healthcare provider. Applying a condom catheter (Choice A) is more suitable for urinary incontinence, not retention. Applying a skin protectant (Choice B) is typically done to prevent skin breakdown in incontinent clients. Encouraging increased fluid intake (Choice C) may be beneficial for some urinary issues but is not the priority intervention for urinary retention.

Correct Answer: A

Rationale: The correct answer is A: 'Folic acid should be taken before and after conception.' Folic acid supplementation before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects. Choice B is incorrect because while multivitamin supplements are beneficial during pregnancy, the specific focus for preventing neural tube defects is on folic acid. Choice C is a general statement about a well-balanced diet and does not specifically address neural tube defects. Choice D is incorrect as it focuses on dietary iron, which is important for overall health but not specifically proven to prevent neural tube defects.

Correct Answer: D

Rationale: The correct answer is D. Clients taking digoxin should avoid eating foods high in potassium, as this can affect the medication's efficacy. Choices A, B, and C are correct statements regarding digoxin administration and precautions, indicating the client's understanding of the medication and its management.
