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 with streptococcal pneumonia is receiving penicillin G by intermittent IV bolus. 10 minutes into the infusion of the third dose, the client reports itching at the IV site, dizziness, and shortness of breath. What should the nurse do first?
- A. Stop the infusion.
- B. Call the provider.
- C. Elevate the head of the bed.
- D. Auscultate breath sounds.
Correct answer: A
Rationale: In this scenario, the client is exhibiting signs of anaphylaxis, a severe allergic reaction. The priority action for the nurse is to stop the infusion immediately to prevent further administration of the allergen and worsening symptoms. Once the infusion is stopped, the nurse can then proceed with additional interventions, such as calling the provider, assessing the client's respiratory status, and providing appropriate care as needed.
3. A client has a new prescription for Propranolol. Which of the following statements should the nurse include in teaching the client?
- A. You may experience a rapid heart rate while taking this medication.
- B. Take the medication with food.
- C. Avoid sudden changes in position.
- D. Increase your intake of high-sodium foods.
Correct answer: C
Rationale: The correct statement to include when teaching a client about Propranolol is to avoid sudden changes in position. Propranolol, a beta-blocker, can lead to dizziness and lightheadedness, particularly when changing positions. Therefore, clients should be advised to change positions slowly to prevent falls and related injuries. Choice A is incorrect because Propranolol actually helps lower heart rate and blood pressure. Choice B is not a specific requirement for taking Propranolol. Choice D is also incorrect as increasing high-sodium foods is not recommended with Propranolol which can affect blood pressure control.
4. A client has a new prescription for clonidine to treat hypertension. Which of the following instructions should the nurse include?
- A. Discontinue the medication if a rash develops.
- B. Expect increased salivation during the first few weeks of therapy.
- C. Avoid driving until the client's reaction to the medication is known.
- D. Stop the medication if you experience a dry mouth.
Correct answer: C
Rationale: The correct instruction for a client starting clonidine therapy for hypertension is to avoid driving until their reaction to the medication is known. Clonidine can cause drowsiness, so engaging in activities like driving that require alertness should be avoided until the individual understands how the medication affects them. Choices A, B, and D are incorrect because they do not address the specific side effect of drowsiness associated with clonidine that could impair driving abilities. Discontinuing the medication if a rash develops, expecting increased salivation, or stopping the medication for dry mouth are not primary concerns related to clonidine therapy for hypertension.
5. A client has a new prescription for methotrexate to treat Rheumatoid Arthritis. The nurse should expect to monitor the client for which of the following adverse effects?
- A. Insomnia
- B. Hypertension
- C. Bone marrow suppression
- D. Constipation
Correct answer: C
Rationale: The correct answer is bone marrow suppression. Methotrexate can lead to bone marrow suppression, resulting in anemia, leukopenia, and thrombocytopenia. Monitoring for signs of decreased blood cell counts is crucial to prevent complications. Insomnia (choice A), hypertension (choice B), and constipation (choice D) are not typically associated with methotrexate use for Rheumatoid Arthritis.
