PN ATI Capstone Proctored Comprehensive Assessment B Quizlet

Correct Answer: D

Rationale: The trough level of vancomycin should be drawn just before the next dose is administered, typically about 30 minutes before the scheduled dose. Since the morning dose is at 0700, the trough level should be drawn at 1800. This timing ensures an accurate measurement of the lowest concentration of the drug in the client's system before the next dose is given. Choice A (2100) is too close to the next dose, choice B (900) is too early, and choice C (1300) is also too far from the next dose.

Correct Answer: C

Rationale: The correct answer is C. Cool feet bilaterally in a client with a long leg cast may indicate compromised circulation, which is a medical emergency that requires immediate intervention. Choices A, B, and D do not present immediate life-threatening conditions. Tingling in the fingers following a thyroidectomy may indicate hypocalcemia but does not require immediate attention. Dark, foul-smelling urine with decreased urine output indicates a possible urinary tract infection or dehydration but can be addressed after attending to the client with compromised circulation. A productive cough and a normal oral temperature do not suggest an urgent condition compared to compromised circulation in a client with a long leg cast.

Correct Answer: A

Rationale: The correct answer is A. Rifampin can cause harmless red-orange discoloration of bodily fluids, including urine, sweat, and tears. Clients should be informed about this side effect. Choice B is incorrect because the duration of rifampin therapy for TB is typically longer than 6 months. Choice C is incorrect as there is no need to avoid dairy products while on rifampin. Choice D is incorrect as rifampin does not cause sensitivity to sunlight.

Correct Answer: B

Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.

Correct Answer: D

Rationale: A pulse of 54/min indicates bradycardia, which is a side effect of propranolol, a beta-blocker. The medication should be withheld if the client's pulse drops below 60/min. The other findings (sodium levels, blood pressure, and potassium levels) are not directly indicative of the need to withhold propranolol.
