Correct Answer: D

Rationale: The correct action for the nurse to implement while awaiting surgery for a client with muscle spasms due to a broken femur is to encourage oral fluid intake to relieve muscle tension. Dehydration can exacerbate muscle spasms, so increasing fluid intake can help alleviate them. Checking electrolyte levels may not directly address muscle spasms in this situation. Administering a muscle relaxant should be based on a healthcare provider's prescription, and traction weight adjustments should only be made by the provider overseeing the client's care.

Correct Answer: A

Rationale: Being aware of cultural differences is crucial because normal behaviors in one culture may be perceived as deviant, immoral, or insane in another. This awareness helps the nurse avoid misunderstandings or misinterpretations of behaviors that are considered acceptable in the client's cultural context but may be viewed differently in another. Choices B, C, and D are incorrect because understanding cultural issues goes beyond deriving meanings from conventional wisdom, personal values guiding interactions, or relying solely on knowledge of developmental mental stages.

Correct Answer: A

Rationale: The correct instruction for the nurse to provide after cataract extraction is to advise the client to avoid straining, bending, or lifting heavy objects. These activities can increase intraocular pressure, which should be minimized post-surgery to promote healing and prevent complications. Choices B, C, and D are incorrect because limiting sunlight exposure, irrigating the conjunctiva with saline, and reading without direct lighting are not primary instructions following cataract extraction.

Correct Answer: D

Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.

Correct Answer: B

Rationale: The correct advice for a client experiencing dizziness when standing up quickly is to change positions slowly to prevent dizziness. This symptom is suggestive of postural hypotension, where a sudden change in position can lead to a drop in blood pressure, causing dizziness. Encouraging the client to drink more fluids (Choice A) may be beneficial for other conditions but is not directly related to the prevention of dizziness in this case. Reporting the symptom to the healthcare provider immediately (Choice C) is important if the dizziness is persistent or severe, but the immediate action to prevent it is to change positions slowly. Limiting physical activity (Choice D) may not necessarily address the underlying cause of dizziness in this context.
