Correct Answer: B

Rationale: The correct answer is B: 'Do you have a plan to end your life?' When a client expresses suicidal thoughts, it is crucial to assess the immediate risk. Inquiring about a specific plan can help determine the seriousness of the situation. Choice A is less direct and may not provide a clear indication of the immediate risk. Choice C focuses on the interpretation of 'misery' rather than assessing the risk of suicide. Choice D offers support but does not address the critical assessment of the client's immediate safety.

Correct Answer: B

Rationale: The correct answer is B: Recent history of dizziness. A recent history of dizziness significantly increases the risk of falling, as dizziness can impair balance and coordination. Having a normal gait (choice A) and 20/20 vision (choice C) are not factors that directly increase the risk of falling. Taking a multivitamin daily (choice D) does not inherently contribute to an increased risk of falling unless it causes dizziness as a side effect, which is not specified in the question.

Correct Answer: B

Rationale: Choice B, 'I might have trouble sleeping when I start this medication,' indicates understanding because insomnia is a common side effect of sertraline, especially when initiating the medication. This statement shows the client comprehends a potential adverse effect and is prepared for it. Choices A, C, and D are incorrect. Taking sertraline with or without meals does not significantly affect its efficacy. There is no specific contraindication about drinking orange juice while on sertraline. Feeling better immediately after starting the medication is unlikely as sertraline usually takes some time to exert its therapeutic effects.

Correct Answer: B

Rationale: To ensure proper functioning of a chest tube, the nurse should keep the drainage system below chest level. This position allows for proper drainage by gravity and prevents backflow into the pleural space. Clamping the chest tube intermittently can lead to a buildup of pressure and should be avoided. Emptying the drainage chamber every 4 hours is important but not directly related to maintaining the chest tube's function. Applying sterile gauze around the insertion site daily is essential for infection prevention but does not specifically ensure the proper functioning of the chest tube.

Correct Answer: B

Rationale: Oatmeal is high in fiber, which helps lower cholesterol levels, making it a heart-healthy food option for clients at risk for cardiovascular disease. Fried chicken, bacon, and whole milk are high in saturated fats and cholesterol, which can increase the risk of heart disease and should be limited in the diet of individuals at risk for cardiovascular issues.
