In which of the following patients would a nurse expect to see an alteration in drug metabolism?
- A. A 35-year-old female with cervical cancer
- B. A 41-year-old male with kidney stones
- C. A 50-year-old male with cirrhosis of the liver
- D. A 62-year-old female in acute renal failure
Correct Answer: C

In cirrhosis patients the drug dosage will need to be altered to ensure normal levels in the body.
A nurse is preparing to administer an intramuscular injection to a patient for the first time. Which of the following would be most important for the nurse to do?
- A. Obtain the patient's allergy history.

- C. Inquire if the patient has any objections to syringes.

Correct Answer: A
Rationale: Before giving any drug for the first time, the nurse should ask the patient about any known allergies as well as any family history of allergies. The nurse need not particularly obtain information about the drug as it has been prescribed by the physician, but needs to be aware of the adverse effects it may cause. There is also no need to discuss the dosage with other nurses or to find out if the client has any objections to syringes. However, the nurse should help allay the patient's fears by reassuring him or her about the administration.
