Correct Answer: A

Rationale: The correct answer is A: Hypertension. In end-stage renal disease, the kidneys are no longer able to regulate blood pressure effectively, leading to hypertension. This can increase the risk of cardiovascular complications. Monitoring for hypertension is crucial in these patients. Rationale for why the other choices are incorrect: B: Hyperglycemia is more commonly associated with diabetes rather than end-stage renal disease. C: Hypothyroidism is a separate condition not directly related to end-stage renal disease. D: Hypokalemia may occur in some cases of renal disease, but hypertension is a more common and critical concern in end-stage renal disease.

Correct Answer: C

Rationale: The correct answer is C because the Montreal Cognitive Assessment (MoCA) is specifically designed to detect delirium and dementia and differentiate these conditions from psychiatric mental illness. It assesses various cognitive domains such as memory, attention, language, and visuospatial abilities. Scores below the normal range on the MoCA can indicate cognitive impairment related to delirium or dementia. Choice A is incorrect because a score below 30 on the MoCA does not necessarily indicate cognitive impairment; it depends on the individual's baseline and education level. Choice B is incorrect because the MoCA primarily focuses on cognitive function rather than mood and thought processes. Choice D is incorrect because while the MoCA can be used for initial evaluation of cognitive function, it is not sufficient for evaluating changes over time. Additional tools and assessments are needed for longitudinal monitoring of cognitive changes.

Correct Answer: A

Rationale: The correct answer is A. A blood pressure reading of 160/100 mm Hg is most concerning because it falls within the hypertensive crisis range, indicating severely elevated blood pressure that requires immediate medical attention to prevent complications like stroke or heart attack. Choices B, C, and D are within the prehypertension or mild hypertension ranges and are not as immediately concerning.

Correct Answer: B

Rationale: The correct answer is B: Encouraging early ambulation. Early ambulation helps prevent complications such as blood clots, improves circulation, aids in lung expansion, and promotes faster recovery. Pain management is important but encouraging mobility is a priority. Administering IV antibiotics is not necessary unless there is an infection present. Monitoring for signs of deep vein thrombosis is important but encouraging ambulation is a proactive approach to prevent its occurrence.
