1. When administering medications to a 4-month-old infant, which of the following pharmacokinetic principles should be considered? (Select all that apply.)
- A. Infants have a more rapid gastric emptying time.
- B. Infants have immature liver function.
- C. Infants' blood-brain barrier is poorly developed.
- D. Infants have an increased ability to absorb topical medications.
Correct answer: B
Rationale: When administering medications to a 4-month-old infant, the pharmacokinetic principle to consider is that infants have immature liver function until 1 year of age. This requires medications metabolized by the liver to be administered in smaller dosages. While infants do have a more rapid gastric emptying time, immature liver function is a more critical pharmacokinetic consideration in this context. Additionally, although infants have a poorly developed blood-brain barrier, this relates more to pharmacodynamic effects rather than pharmacokinetic principles. The statement about infants having an increased ability to absorb topical medications is not directly related to pharmacokinetic principles, making choice B the correct answer.
2. A client has a new prescription for Efavirenz, an NNRTI. Which of the following instructions should the nurse include?
- A. Take this medication at bedtime to prevent drowsiness.
- B. Take this medication with a glass of milk.
- C. Take this medication with a glass of juice.
- D. Take this medication at the same time every day.
Correct answer: A
Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.
3. A healthcare provider is caring for a group of clients who are not protected against Varicella. The healthcare provider should prepare to administer the Varicella vaccine at this time to which of the following clients?
- A. 24-year-old woman in the third trimester of pregnancy
- B. 12-year-old child who has a severe allergy to neomycin
- C. 2-month-old infant who has no health problems
- D. 32-year-old man who has essential hypertension
Correct answer: D
Rationale: The correct answer is the 32-year-old man who has essential hypertension. Individuals who did not receive two doses of the varicella vaccine earlier in life should be immunized. Essential hypertension is not a contraindication for this vaccine, making it safe to administer to this client. Choice A is incorrect because administering the Varicella vaccine is contraindicated during pregnancy due to the risk of transmission to the fetus. Choice B is incorrect because a severe allergy to neomycin is a contraindication to the Varicella vaccine, which contains a trace amount of neomycin. Choice C is incorrect because the Varicella vaccine is not recommended for infants under 12 months of age.
4. A client with peptic ulcer disease is prescribed sucralfate. Which of the following instructions should the nurse include?
- A. Take sucralfate with meals.
- B. Take sucralfate 1 hr before meals.
- C. Take sucralfate with antacids.
- D. Take sucralfate 2 hours after meals.
Correct answer: B
Rationale: The correct instruction for taking sucralfate is 1 hour before meals. This timing allows sucralfate to effectively coat the stomach lining and provide a protective barrier against gastric acid, helping to prevent ulcers.
5. A healthcare professional is preparing to administer verapamil by IV bolus to a client who is experiencing cardiac dysrhythmias. For which of the following adverse effects should the healthcare professional monitor when giving this medication?
- A. Hyperthermia
- B. Hypotension
- C. Ototoxicity
- D. Muscle pain
Correct answer: B
Rationale: Verapamil is known to cause hypotension as one of its adverse effects due to its vasodilatory properties. Therefore, it is essential for the healthcare professional to monitor the client's blood pressure closely during and after administration to prevent complications such as severe hypotension. Hyperthermia, ototoxicity, and muscle pain are not commonly associated with verapamil administration, making choices A, C, and D incorrect.
