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 healthcare professional is reviewing laboratory results for a client who is receiving heparin via continuous IV infusion. Which of the following results indicates that the heparin infusion should be increased?

• A. aPTT of 90 seconds
• B. Platelet count of 150,000/mm³
• C. INR of 1.0
• D. Hgb of 15 g/dL

Correct answer: A

Rationale: An aPTT of 90 seconds is above the therapeutic range for heparin, which typically falls between 60-80 seconds. This indicates that the current heparin dose is too high, and the infusion rate should be decreased to avoid excessive anticoagulation and the risk of bleeding. Monitoring aPTT is crucial in adjusting heparin therapy to maintain it within the therapeutic range.

3. A client has a new prescription for Sucralfate. Which of the following instructions should the nurse include?

• A. Take the medication on an empty stomach.
• B. Increase your intake of high-sodium foods.
• C. Take the medication with a full glass of milk.
• D. Expect your stools to be black and tarry.

Correct answer: A

Rationale: The correct instruction that the nurse should include for a client prescribed Sucralfate is to take the medication on an empty stomach. Sucralfate works by forming a protective barrier over ulcers, which is most effective when the stomach is empty. Taking it with food or other medications may decrease its effectiveness. Instructing the client to take Sucralfate on an empty stomach helps ensure optimal therapeutic benefits. Choices B, C, and D are incorrect because increasing high-sodium foods is not related to Sucralfate therapy, taking the medication with a full glass of milk is not recommended as it may decrease its effectiveness, and the presence of black and tarry stools is not an expected outcome of Sucralfate.

4. A drug ending in the suffix (azole) is considered a ______.

• A. H
• B. ACE inhibitor
• C. Antifungal
• D. Beta agonist

Correct answer: C

Rationale: Drugs ending in the suffix -azole are commonly associated with antifungal medications. Examples include fluconazole, ketoconazole, and itraconazole. These medications are used to treat fungal infections by inhibiting the growth of fungi. Therefore, the correct answer is option C, 'Antifungal'. Options A, B, and D do not accurately describe drugs ending in -azole.

5. A client taking nitroglycerin (Nitrostat) for angina asks the nurse to explain possible side effects. What should NOT be included in client teaching?

• A. Reflex tachycardia
• B. Dizziness
• C. Hyponatremia
• D. Hypotension

Correct answer: C

Rationale: Hyponatremia is not a common side effect associated with nitroglycerin use. Nitroglycerin typically causes side effects such as reflex tachycardia, dizziness, and hypotension due to its vasodilatory effects. Therefore, it is important for the nurse to educate the client about these potential side effects to promote understanding and appropriate management.
