Correct Answer: B

Rationale: The correct answer is B: Beef. While beef is a good source of protein, it is not high in phosphate. Milk, poultry, and liver are high in phosphate and would be beneficial for a patient with hypophosphatemia. Beef is not typically a significant source of phosphate and therefore would not be as effective in increasing phosphate levels in the body compared to the other options. It is important for the patient to focus on consuming foods that are high in phosphate to help correct the hypophosphatemia.

Correct Answer: C

Rationale: The correct answer is C. Reading food labels to determine sodium content is important in managing mild hypernatremia. This allows the client to monitor and control their sodium intake, which can help prevent further elevation of sodium levels. Weighing oneself or checking the pulse does not directly address sodium intake. Choosing cooking methods like baking or grilling is more about reducing fat intake, not sodium.

Correct Answer: D

Rationale: The correct answer is D because dangling the client on the bedside before ambulating helps prevent orthostatic hypotension and potential falls. This step allows the nurse to assess the client's tolerance to changes in position and reduces the risk of injury. A: Asking family members to speak quietly does not directly address the prevention of injury related to dehydration. B: Assessing urine parameters is important for monitoring hydration status but does not directly prevent injury. C: Encouraging fluid intake is important for rehydration but does not directly address the risk of injury during ambulation.

Correct Answer: C

Rationale: Rationale: Guillain-Barr syndrome can cause inadequate ventilation due to paralysis of the respiratory muscles. This results in respiratory acidosis. Endocarditis, multiple myeloma, and amphetamine overdose do not directly affect ventilation. Endocarditis is an infection of the heart valves, multiple myeloma is a cancer of plasma cells, and amphetamine overdose primarily affects the central nervous system and cardiovascular system, not ventilation. Therefore, Guillain-Barr syndrome is the most likely diagnosis in this case.

Correct Answer: B

Rationale: The correct answer is B because limiting fluids can lead to dehydration, which can cause confusion and dry mucous membranes. Adjusting the timing of fluids can help maintain hydration without causing frequent nighttime bathroom trips. Choice A is incorrect because hospital readmission is not necessary at this point. Choice C is incorrect as it normalizes confusion post-surgery and dangerous practice of avoiding urination at night. Choice D is incorrect because urine accumulation in the bladder does not directly cause confusion; dehydration is the primary concern.
