,NR 293 Pharmacology for Nursing - Infection & Antimicrobials 2026/2027 UPDATE
1. A patient is prescribed a sulfonamide for a urinary tract infection. Which instruction is most
critical for the nurse to include in the discharge teaching to prevent crystalluria?
A. Avoid taking the medication with dairy products.
B. Take the medication with an antacid to prevent GI upset.
C. Increase fluid intake to at least 2000 to 3000 mL per day.
D. Limit sunlight exposure and use high-SPF sunscreen.
Answer: C
Rationale: Sulfonamides can cause crystalluria in the kidneys. Promoting high fluid intake
helps flush the kidneys and prevent stone formation. While photosensitivity (D) is a side
effect, preventing renal damage (C) is a physiological priority.
2. A patient with a known severe anaphylactic reaction to Penicillin G is prescribed Cefazolin.
What is the priority nursing action?
A. Hold the medication and notify the healthcare provider due to potential cross-sensitivity.
B. Administer the Cefazolin and monitor the patient closely for 30 minutes.
C. Pre-medicate the patient with diphenhydramine before administration.
D. Ask the patient if they have ever taken Cephalosporins before.
, Answer: A
Rationale: There is a cross-sensitivity (about 1-4%) between penicillins and
cephalosporins. If the patient has had a life-threatening anaphylactic reaction to penicillin,
cephalosporins should be avoided unless no alternative exists and strict supervision is
provided.
3. Which adverse effect is a patient taking Tetracycline at highest risk for if they are also
taking an oral contraceptive?
A. Increased risk of deep vein thrombosis.
B. Potential for permanent tooth discoloration.
C. Reduced effectiveness of the contraceptive.
D. Severe photosensitivity reactions.
Answer: C
Rationale: Antibiotics, particularly tetracyclines and penicillins, can decrease the
effectiveness of oral contraceptives. Patients should be advised to use a backup method of
birth control.
4. A nurse is preparing to administer Gentamicin to a patient. Which laboratory values should
be monitored closely to assess for toxicity?
A. ALT and AST
B. Amylase and Lipase
