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 in a long-term care facility has Hypothyroidism and a new prescription for Levothyroxine. Which of the following dosage schedules should the nurse expect for this client?
- A. The client will start at a high dose, and the dose will be tapered as needed.
- B. The client will remain on the initial dosage during the course of treatment.
- C. The client's dosage will be adjusted daily based on blood levels.
- D. The client will start on a low dose, which will be gradually increased.
Correct answer: D
Rationale: The nurse should expect that levothyroxine will be started at a low dose and gradually increased over several weeks. This cautious approach is crucial, especially in older adult clients, to prevent toxicity and ensure optimal therapeutic outcomes for managing hypothyroidism. Choice A is incorrect because starting at a high dose and tapering as needed is not the standard approach for levothyroxine. Choice B is incorrect because the initial dosage is typically adjusted to reach the optimal therapeutic dose. Choice C is incorrect as adjusting the dosage daily based on blood levels is not necessary for levothyroxine, as it has a long half-life and requires time to reach a steady state.
3. A client has a new prescription for Zolpidem. Which of the following instructions should the nurse include?
- A. Notify the provider if you plan to become pregnant.
- B. Take the medication 1 hour before planning to go to sleep.
- C. Allow at least 6 hours for sleep when taking zolpidem.
- D. Do not take zolpidem with a bedtime snack.
Correct answer: A
Rationale: Zolpidem is classified as Pregnancy Risk Category C. It is important for the client to inform the provider if they plan to become pregnant because the medication may need to be adjusted or changed to ensure the safety of the fetus. This communication allows for appropriate monitoring and adjustments to be made to the treatment plan. Choice B is incorrect because zolpidem should be taken just before going to bed, not specifically 1 hour before. Choice C is incorrect as zolpidem is a short-acting medication, and it does not require a full 6 hours for sleep. Choice D is incorrect because zolpidem can be taken with or without food, so taking it with a bedtime snack is not contraindicated.
4. A client has a new prescription for Verapamil to control hypertension. Which of the following instructions should the nurse include?
- A. Increase the amount of dietary fiber in the diet.
- B. Drink grapefruit juice daily to increase vitamin C intake.
- C. Decrease the amount of calcium in the diet.
- D. Withhold food for 1 hr after taking the medication.
Correct answer: A
Rationale: Increasing dietary fiber intake is essential when taking Verapamil to prevent constipation, a common adverse effect of this medication. Verapamil is a calcium channel blocker used to treat hypertension, and dietary fiber helps maintain bowel regularity and prevent constipation that may occur as a side effect of the medication.
5. A client is receiving discharge instructions for a new prescription of Prednisone. Which of the following dietary instructions should be included?
- A. Increase your intake of potassium-rich foods.
- B. Increase your intake of dairy products.
- C. Avoid foods high in vitamin K.
- D. Decrease your intake of protein.
Correct answer: A
Rationale: When a client is prescribed Prednisone, there is a risk of potassium depletion due to the medication. Therefore, it is essential to increase the intake of potassium-rich foods such as bananas, oranges, and spinach to help maintain adequate potassium levels in the body and prevent complications associated with low potassium levels. Choice B and D are incorrect as there is no specific need to increase dairy products or decrease protein intake with Prednisone. Choice C is also incorrect as avoiding foods high in vitamin K is more relevant for clients taking anticoagulants like warfarin.
