Question 1 of 5
Which of the following client findings should the nurse identify as a contraindication to the administration of furosemide? (Client with potassium 3.2 mEq/L)
Correct Answer: A
Rationale: Hypokalemia (3.2 mEq/L) is a contraindication as furosemide can worsen it, risking arrhythmias.

Question 2 of 5
A nurse is preparing to administer epoetin 50 units/kg via subcutaneous injection to a client who weighs 165 lb and has chronic kidney disease. How many units should the nurse administer?
Correct Answer: A
Rationale: 165 lb = 75 kg; 50 units/kg × 75 kg = 3750 units, correct for stimulating RBC production in CKD.
Question 3 of 5
A nurse is preparing to administer filgrastim 6 mcg/kg subcutaneously to a client who weighs 110 lb. Available is filgrastim solution for injection 480 mcg/0.8 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: C
Rationale:
To calculate the correct dose, convert the client's weight from pounds to kilograms (110 lb ÷ 2.2 = 50 kg). Filgrastim is dosed at 6 mcg/kg, so 6 mcg/kg × 50 kg = 300 mcg needed. The available concentration is 480 mcg in 0.8 mL. Set up the proportion: (300 mcg ÷ 480 mcg) × 0.8 mL = 0.5 mL. Option A (0.3 mL) underdoses at 180 mcg, Option B (0.4 mL) gives 240 mcg, and Option D (0.6 mL) overdoses at 360 mcg. Option C (0.5 mL) delivers exactly 300 mcg, matching the prescribed dose. Rounding to the nearest tenth, 0.5 mL is correct with no trailing zero, adhering to medication safety standards. This calculation ensures therapeutic efficacy (e.g., boosting white blood cells) while minimizing risks like overdose-related bone pain or underdose-related infection susceptibility, making C the precise and safe choice.
Question 4 of 5
A nurse is assisting with the care of a postoperative client who has developed malignant hyperthermia. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: A cooling blanket lowers body temperature in malignant hyperthermia, a life-threatening condition. Meperidine, warm enemas, and oxygen alone don't address the hyperthermia directly.
Question 5 of 5
A nurse administered a dose of penicillin to a client 30 min ago. The client reports she has hives and is itching. Which of the following statements by the nurse is the highest priority?
Correct Answer: C
Rationale: Asking about difficulty breathing is the priority as it assesses for anaphylaxis, a life-threatening allergic reaction to penicillin, requiring immediate intervention.
