Wgu RN HESI Pharmacology Questions

Extract:


Question 1 of 5

The nurse administers the initial dose of cefoxitin to a client whose medical record indicates an allergy to penicillin. Which finding is most important for the nurse to report to the healthcare provider?

Correct Answer: B

Rationale: Pruritis and rash suggest a possible allergic reaction to cefoxitin, a cephalosporin, due to cross-reactivity with penicillin. This requires immediate reporting. Renal output, GI symptoms, and vaginal discharge are less specific to allergic responses.

Question 2 of 5

Which intervention is most important for the nurse to implement for a client with type 2 diabetes mellitus (DM) who is receiving insulin lispro?

Correct Answer: D

Rationale: Insulin lispro, rapid-acting, peaks 1-2 hours post-dose, requiring meals shortly after to prevent hypoglycemia. Synchronizing meal timing is critical. Glucose sources, monitoring, and hypoglycemia checks are secondary.

Question 3 of 5

The healthcare provider prescribes propylthiouracil (PTU) and Lugol’s solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?

Correct Answer: B

Rationale: Lugol’s solution reduces thyroid hormone production, enhancing PTU’s inhibition of hormone synthesis. Administering iodine one hour before PTU optimizes efficacy. Bedtime, parenteral, or meal-time administration are incorrect.

Question 4 of 5

A client receives a prescription for penicillin G 1,000,000 units intramuscular (IM) daily. The medication is available in 1,200,000 units/2 mL syringe. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Correct Answer: 1.7

Rationale: Calculate: (1,000,000 units ÷ 1,200,000 units) × 2 mL = 1.67 mL, rounded to 1.7 mL. This ensures the correct dose of penicillin G is administered intramuscularly.

Question 5 of 5

A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?

Correct Answer: B

Rationale: Erythromycin may reduce oral contraceptive efficacy. Additional contraception (e.g., condoms) prevents pregnancy. Stopping contraceptives, spacing doses, or avoiding sunlight are incorrect.
