Question 1 of 5
A client with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate?
Correct Answer: B
Rationale: Open-angle glaucoma requires lifelong eye drops to control intraocular pressure (
B), preventing optic nerve damage. Angle restoration (
A), temporary pressure reduction (
C), and pain/swelling (
D) are incorrect.
Question 2 of 5
A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client’s history, the nurse determines that the client has been self-administering St. John's Wort, an herbal preparation on the advice of a friend. Which information is most significant about this finding?
Correct Answer: B
Rationale: St. John’s Wort induces cytochrome P450 enzymes, reducing cyclosporine levels (
B), an immunosuppressant, risking graft rejection. Depression use (
A) is possible but less critical. Sodium (
C) and corticosteroids (D, E) are unrelated.
Choice E is a duplicate.
Question 3 of 5
Which assessment data indicated to the nurse that a client is having an anaphylactic reaction to a medication?
Correct Answer: D
Rationale: Anaphylaxis is a severe allergic reaction involving multiple systems. Wheezing and dyspnea (
D) indicate respiratory involvement, a hallmark of anaphylaxis, requiring urgent intervention. Urticaria/pruritis (
A) are common but less specific. Insomnia/irritability (
B) and tinnitus/diplopia (
C) are unrelated.
Question 4 of 5
Prior to administering oral doses of calcitriol and calcium carbonate to a client with hypoparathyroidism, the nurse notes that the total level of calcium is 14 mg/dL (3.5 mmol/L). Which action should the nurse implement?
Correct Answer: D
Rationale: A calcium level of 14 mg/dL (3.5 mmol/L) indicates hypercalcemia (normal: 8.5-10.2 mg/dL). Calcitriol and calcium carbonate increase calcium levels, risking toxicity. Holding both and contacting the provider (
D) is safest.
Question 5 of 5
Prior to administering the evening dose of carbamazepine, the nurse noted that the client’s morning carbamazepine level was 8.4 mg/L. Which action should the nurse take?
Correct Answer: D
Rationale: A carbamazepine level of 8.4 mg/L is therapeutic (4-12 mg/L). Administering the dose (
D) is appropriate. Withholding (
A), notifying (
B), or assessing side effects (
C) are unnecessary.
