When assessing a patient before starting a drug regimen, why would the nurse consider it important to assess baseline kidney function?
- A. To anticipate adverse effects of drugs
- B. To determine patient's baseline electrolyte levels
- C. To determine patient's ability to excrete the drug
- D. To determine patient's ability to metabolize the drug
Correct Answer: C
Rationale: Kidney function determines drug excretion, critical for dosing and avoiding toxicity.

- A. There may be an antagonistic reaction between the two
- B. The additive effects may include bradycardia

The nurse uses what term to describe the drug level required to have a therapeutic effect?
- A. Critical concentration
- B. Dynamic equilibrium
- C. Selective toxicity
- D. Active transport
Correct Answer: A
Rationale: A critical concentration of a drug must be present before a reaction occurs within the cells to bring about the desired therapeutic effect. A dynamic equilibrium is obtained from absorption of a drug from the site of drug entry, distribution to the active site, metabolism in the liver, and excretion from the body to have a critical concentration. Selective toxicity is the ability of a drug to attach only to those systems found in foreign cells. Active transport is the process that uses energy to actively move a molecule across a cell membrane and is often involved in drug excretion in the kidney.
