A male client arrives at the mental health clinic and asks the nurse for more lithium and the antidepressant amitriptyline that he uses to help him sleep. After reviewing the assessment findings with the healthcare provider, a serum creatinine is obtained. Which information supports the reason for this laboratory test?
Creatinine can measure how the body is metabolizing the lithium in the liver.
The effects of amitriptyline can promote and potentiate the risk of lithium toxicity.
The combination of lithium and amitriptyline may need to be changed if creatinine is high.
Lithium is excreted by the kidneys, and creatinine is related to kidney functioning.
The Correct Answer is D
A. Creatinine primarily reflects kidney function, not the metabolism of lithium in the liver.
B. Amitriptyline's effects on lithium toxicity are not directly related to creatinine levels.
However, both drugs can impact kidney function.
C. The decision to change medication based on creatinine levels involves assessing the impact on kidney function, not the combination of lithium and amitriptyline per se.
D. Lithium is excreted by the kidneys, and monitoring creatinine levels helps assess renal function, guiding the appropriate dosage and preventing lithium toxicity.

Correct Answer is A
Explanation
A. The client's statements about having an IQ of 400+, being married to a movie star, and suspecting his brother's intentions may indicate a distorted perception of reality, suggesting disturbed sensory perception. This priority addresses the potential psychosis and immediate safety concerns.
B. Compromised family coping, while important, is a secondary consideration. Addressing the client's altered sensory perception takes precedence to ensure their safety and
stabilization.
C. Ineffective sexual patterns are not as immediate concerns as the potential distorted sensory perception. Ensuring the client's mental stability is the primary goal upon admission to the psychiatric unit.
D. Impaired environmental interpretation is not as immediate concerns as the potential distorted sensory perception. Ensuring the client's mental stability is the primary goal upon admission to the psychiatric unit.
