A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include that a severe allergy to which of the following medications is a contraindication to ceftriaxone?
- A. Gentamicin
- B. Clindamycin
- C. Piperacillin
- D. Sulfamethoxazole-trimethoprim
Correct Answer: C
Rationale: The correct answer is C. Ceftriaxone, a cephalosporin antibiotic, has a cross-sensitivity with penicillin antibiotics like piperacillin. Therefore, a severe allergy to penicillin or penicillin-related antibiotics would be a contraindication to ceftriaxone. Choices A, B, and D are incorrect because they are not associated with a known cross-sensitivity with ceftriaxone.

A nurse is preparing to administer iron dextran IV to a client. Which of the following actions should the nurse plan to take?
- A. Administer a small test dose before giving the full dose
- B. Infuse the medication over 30 seconds
- C. Monitor client closely for hypertension
- D. Administer cyanocobalamin as an antidote if toxicity occurs
Correct Answer: A
Rationale: The correct action the nurse should plan to take when preparing to administer iron dextran IV is to administer a small test dose before giving the full dose. This is done to assess for any allergic reactions that the client may have to the medication. Choice B is incorrect because iron dextran should be infused slowly over a longer period, typically over 1-2 hours to reduce the risk of adverse reactions. Choice C is incorrect because iron dextran administration is more commonly associated with hypotension rather than hypertension. Choice D is incorrect because cyanocobalamin is not used as an antidote for iron dextran toxicity; instead, treatment for iron toxicity may involve supportive care, chelation therapy, or in severe cases, iron antidotes like deferoxamine.
A nurse is providing teaching to a newly licensed nurse about caring for a client who has a prescription for gemfibrozil. The nurse should instruct the newly licensed nurse to monitor which of the following laboratory tests?
- A. Platelet count
- B. Electrolyte levels
- C. Thyroid function
- D. Liver function
Correct Answer: D
Rationale: The correct answer is D: Liver function. Gemfibrozil can lead to hepatotoxicity, making it crucial to monitor liver function tests. Monitoring platelet count (choice A) is not specifically indicated for gemfibrozil. Electrolyte levels (choice B) and thyroid function (choice C) are not directly affected by gemfibrozil, so they are not the primary laboratory tests to monitor in this case.
A nurse is caring for a client who has a prescription for clopidogrel. The nurse should monitor the client for which of the following adverse effects?
- A. Insomnia
- B. Hypotension
- C. Bleeding
- D. Constipation
Correct Answer: C
Rationale: The correct answer is C: Bleeding. Clopidogrel is an antiplatelet medication that works by preventing platelets from sticking together and forming clots. Therefore, one of the main adverse effects of clopidogrel is an increased risk of bleeding. Insomnia (Choice A), hypotension (Choice B), and constipation (Choice D) are not commonly associated with clopidogrel use. Monitoring for signs of bleeding, such as easy bruising, petechiae, or prolonged bleeding from minor cuts, is crucial when a client is taking clopidogrel.
A client with gout is prescribed allopurinol. The nurse should instruct the client to discontinue taking the medication for which of the following adverse effects?
- A. Nausea
- B. Metallic taste
- C. Fever
- D. Drowsiness
Correct Answer: C
Rationale: The correct answer is C: Fever. Fever can indicate a serious hypersensitivity reaction to allopurinol, known as allopurinol hypersensitivity syndrome, which can be severe and even life-threatening. Nausea and drowsiness are common side effects of allopurinol but not necessarily indications to discontinue the medication. Metallic taste is not typically associated with allopurinol use. Therefore, the nurse should emphasize to the client the importance of reporting any signs of fever promptly for further evaluation and management.
A nurse is preparing to administer furosemide 4 mg/kg/day PO divided into 2 equal doses daily to a toddler who weighs 22 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number)
- A. 20 mg
- B. 15 mg
- C. 10 mg
- D. 30 mg
Correct Answer: A
Rationale: To calculate the dosage per dose, first, convert the toddler's weight from pounds to kilograms: 22 lb / 2.2 = 10 kg. Then, multiply the weight by the dosage: 4 mg 10 kg = 40 mg/day. Since this total daily dose is divided into 2 equal doses, the nurse should administer 20 mg per dose. Therefore, the correct answer is 20 mg. Choice B (15 mg) is incorrect because it does not account for the correct weight conversion and dosage calculation. Choice C (10 mg) is incorrect as it only considers the weight conversion but doesn't multiply it by the dosage. Choice D (30 mg) is incorrect as it miscalculates the dosage by not dividing the total daily dose into 2 equal parts.
