The nurse is caring for an older adult patient who is receiving multiple medications. When monitoring this patient for potential drug toxicity, the nurse should review which lab values closely?

Complete blood count and serum glucose levels

Pancreatic enzymes and urinalysis

Serum creatinine and liver function tests (LFTs)

Serum lipids and electrolytes

Answer and Explanation

The Correct Answer is C

A. Complete blood count (CBC) and serum glucose levels are important for overall health monitoring but do not specifically assess drug metabolism or excretion, which are key factors in drug toxicity.

B. Pancreatic enzymes and urinalysis are useful for detecting pancreatic disorders and infections but are not primary indicators of drug toxicity.

C. Serum creatinine and liver function tests (LFTs) are critical for monitoring drug toxicity, especially in older adults. The kidneys and liver are responsible for drug metabolism and excretion. Impaired kidney function, indicated by elevated serum creatinine, can lead to drug accumulation and toxicity. Abnormal LFTs suggest liver dysfunction, which can affect drug metabolism and increase toxicity risk.

D. Serum lipids and electrolytes are important for cardiovascular and metabolic health but do not directly assess drug metabolism or toxicity risk.

Correct Answer is A

Explanation

A. Schedule II drugs are controlled substances with a high potential for abuse. Proper disposal requires a witness, usually another nurse, to verify and cosign the waste to ensure accountability and prevent diversion.

B. Keeping the remaining drug in the patient’s drawer is unsafe and violates controlled substance regulations. Single-use vials should not be stored for later use.

C. While documentation of administered medication is necessary, simply recording the unused amount in the patient’s chart is insufficient. Controlled substances require proper disposal with a witness.

D. Controlled substances cannot be discarded in a general locked collection box without proper witnessing and documentation. The correct procedure is to have another nurse verify and cosign the waste before disposal.

A. Children cannot give consent, so clinical drug trials are not performed on children. B. Children can only be subjects in quasi-experimental clinical studies. C. Data from adult clinical drug trials can be extrapolated to children. D. Federal law requires that drugs for children be tested on children.

Correct Answer is D

Explanation

a) Children can participate in clinical drug trials when appropriate consent is obtained from parents or guardians and when the study complies with ethical guidelines. They are not excluded from trials entirely because they cannot give consent.

b) Children can participate in various types of clinical studies, not just quasi-experimental ones, as long as the study follows ethical and legal guidelines for pediatric research.

c) Data from adult clinical trials cannot always be directly applied to children due to physiological differences. Pediatric drug testing is necessary to ensure drugs are both safe and effective for children.

d) Federal law mandates that drugs for children undergo testing in pediatric populations. This is to ensure that drugs are safe and effective for children, as they may respond differently than adults to medications.
