A nurse is reviewing the BUN result of a client who is taking cyclosporine following a kidney transplant. Which of the following laboratory studies should the nurse recognize as another renal function study that should be monitored?
Creatinine
Alkaline phosphatase
Bilirubin
Amylase
The Correct Answer is A
Rationale:
A. Creatinine: Serum creatinine is a key indicator of renal function. Cyclosporine is nephrotoxic, so monitoring both BUN and creatinine helps detect early signs of kidney impairment or transplant rejection.
B. Alkaline phosphatase: This enzyme primarily reflects liver and bone activity, not renal function. It is not routinely used to evaluate kidney status.
C. Bilirubin: Bilirubin levels are used to assess liver function and hemolytic disorders, not kidney function.
D. Amylase: Amylase is an enzyme related to pancreatic function and used to diagnose pancreatitis, not renal impairment.

Correct Answer is C
Explanation
Rationale:
A. After inflation, deflate a blood pressure cuff on the client's arm while palpating their brachial pulse: This technique assesses blood pressure, not pulse deficit. Pulse deficit requires comparing simultaneous heartbeats at different sites rather than using a cuff for measurement.
B. Compare the client's carotid pulse while resting to their carotid pulse after standing for 1 min: This evaluates orthostatic changes in heart rate, not pulse deficit. Pulse deficit specifically identifies a difference between apical and peripheral pulses during the same cardiac cycle.
C. Measure the client's apical pulse while another nurse measures their radial pulse: A pulse deficit is determined by counting the apical pulse and comparing it to the radial pulse simultaneously. A difference indicates that some heartbeats are not producing a palpable peripheral pulse, which is important in conditions like atrial fibrillation.
D. Assess both of the client's radial pulses at the same time and compare the quality of pulsations: Comparing radial pulses on both sides evaluates for peripheral pulse equality or arterial obstruction, not pulse deficit.
Correct Answer is B
Explanation
Rationale:
A. Diabetes mellitus: Diabetes is not a direct contraindication or risk factor for complications from electroconvulsive therapy (ECT). Blood glucose should be monitored, but it does not increase procedural risk.
B. Subdural hematoma: A subdural hematoma increases the risk of complications during ECT because the induced seizure can elevate intracranial pressure, potentially worsening the hematoma or causing neurological deterioration. This is a significant safety consideration.
C. Hyperthyroidism: While hyperthyroidism can affect cardiovascular response, it is not as high-risk as intracranial pathology. Pre-procedure assessment may include thyroid function evaluation if indicated.
D. Renal calculi: Kidney stones do not increase the risk of ECT complications. This condition is unrelated to seizure induction or anesthetic considerations.
