Extract:
Question 1 of 5
A nurse is preparing to mix NPH insulin and regular insulin for administration. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Injecting air into each vial equalizes pressure for accurate withdrawal; regular insulin is drawn first, then NPH. Tuberculin syringes aren't standard, NPH isn't withdrawn first, and shaking regular insulin risks bubbles.
Question 2 of 5
A nurse is caring for a client who is receiving acetaminophen for mild pain. The nurse should monitor the client for which of the following adverse effects of this medication?
Correct Answer: B
Rationale: Jaundice, indicating potential liver damage, is a rare but serious adverse effect of acetaminophen overdose that the nurse should monitor for. Fever reduction is a therapeutic effect, while diarrhea and tinnitus are not typical side effects.
Question 3 of 5
A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: 44 lb = 20 kg; 6 mg/kg/day = 120 mg/day; 120 mg / 3 doses = 40 mg/dose; 40 mg / 40 mg/mL = 1 mL/dose, rounded to 1 mL.
Question 4 of 5
A nurse is caring for an older adult client who has heart failure and a prescription for a repeat dose of furosemide 40 mg orally. Which of the following actions is the nurse's priority?
Correct Answer: D
Rationale: Reviewing electrolyte levels is the priority before giving furosemide, a diuretic that can cause imbalances (e.g., hypokalemia), especially in heart failure patients. Other actions follow this safety check.
Question 5 of 5
A nurse is obtaining a medication history from a client who has systemic lupus erythematosus (SLE) and reports taking several herbal supplements daily. The nurse should identify that SLE is a contraindication for taking which of the following herbal supplements?
Correct Answer: C
Rationale: Echinacea boosts the immune system, which can worsen autoimmune conditions like SLE. Flaxseed, glucosamine, and ginger are not contraindicated and may even offer anti-inflammatory benefits.
