Correct Answer: D

Rationale: The client is likely experiencing spinal fluid leakage (post-lumbar puncture headache), a common complication of a lumbar puncture. This leakage results in a reduction of cerebrospinal fluid volume around the brain and spinal cord, leading to a headache that worsens when in an upright position due to reduced buoyancy. A migraine headache (Choice A) is not typically associated with a lumbar puncture. Infection from the puncture site (Choice B) would present with localized signs of inflammation, such as redness, swelling, and warmth, rather than worsening headache. Low blood sugar (Choice C) is not a common complication of lumbar puncture and would not typically manifest as a worsening headache when sitting up.

Correct Answer: B

Rationale: The correct answer is B. Alendronate (Fosamax) should be taken with a full glass of water in the morning to prevent esophageal irritation and ensure proper absorption. Choice A is incorrect because taking alendronate at bedtime increases the risk of esophageal irritation due to lying down. Choice C is incorrect because patients should remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.

Correct Answer: B

Rationale: In hyperthyroidism, there is an increase in metabolism, leading to symptoms such as increased appetite, weight loss, and heat intolerance. Therefore, the nurse should expect an increased appetite in a client with hyperthyroidism. Choices A, C, and D are incorrect because decreased heart rate and cold intolerance are more commonly associated with hypothyroidism, while weight gain is not typically seen in hyperthyroidism.

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.

Correct Answer: C

Rationale: In sepsis with multi-organ failure, monitoring intake and output is critical to assess renal function and fluid balance, as organ failure can cause fluid shifts and decreased kidney function. Antibiotics are essential to treat the infection, but monitoring intake and output provides real-time insight into the client's status, helping to detect early signs of worsening organ function. Early ambulation and blood glucose monitoring are important aspects of care but are not as crucial as maintaining strict intake and output in this situation.
