Question 1 of 5
A patient is currently on an oral contraceptive and has been prescribed erythromycin. What advice should the nurse provide to the patient?
Correct Answer: A
Rationale: Erythromycin may reduce oral contraceptive efficacy by inducing hepatic metabolism. Using an additional contraceptive method (
A) prevents unintended pregnancy. Discontinuing the contraceptive (
B) is unnecessary. Timing gaps (
C) don’t mitigate the interaction. Sunlight avoidance (
D) relates to other antibiotics like tetracycline.
Question 2 of 5
Before administering the evening dose of carbamazepine, the nurse notes that the patient’s morning carbamazepine level was 84 mcg/mL. What action should the nurse take?
Correct Answer: A
Rationale: Carbamazepine’s therapeutic range is 4-12 mcg/mL; 84 mcg/mL (
A) indicates toxicity risk, requiring provider notification. Administering (
B) or withholding (
C) without consultation is unsafe. Assessing side effects (
D) is secondary to reporting.
Question 3 of 5
After taking orlistat for one week, a female patient tells the home health nurse that she is experiencing increasingly frequent oily stools and gas. What action should the nurse take?
Correct Answer: A
Rationale: Orlistat inhibits fat absorption, causing oily stools and gas if dietary fat is high. Assessing dietary intake (
A) identifies the cause. Stopping the drug (
B) is premature. Increasing fats (
C) worsens symptoms. Stool testing (
D) is unnecessary for known side effects.
Question 4 of 5
A patient who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. During the patient’s history taking, the nurse finds out that the patient has been self-administering St. John’s Wort, an herbal preparation, on a friend’s advice. What information is most significant about this finding?
Correct Answer: A
Rationale: St. John’s Wort induces CYP3A4, reducing cyclosporine levels (
A), risking transplant rejection. It doesn’t affect sodium (
B) or reduce corticosteroid needs (
C). Depression treatment (
D) is secondary to the transplant risk.
Question 5 of 5
A client with benign prostatic hyperplasia has been prescribed tamsulosin. What should the nurse do to monitor for an adverse reaction?
Correct Answer: A
Rationale: This question is identical to Question 29. Tamsulosin can cause hypotension (
A), necessitating blood pressure monitoring. Urine output (
B), bladder scans (
C), and weights (
D) don’t address adverse effects. Note: Duplicate question; consider removing.
