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 been prescribed Valsartan. Which of the following adverse effects should the nurse monitor?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Bradycardia
- D. Hypercalcemia
Correct answer: A
Rationale: Corrected Rationale: Valsartan is an angiotensin II receptor blocker (ARB) that can lead to hyperkalemia by inhibiting the action of aldosterone. Hyperkalemia is a potential adverse effect, making it essential for the nurse to closely monitor the client's potassium levels to prevent complications such as cardiac arrhythmias. Incorrect Options Rationale: - Option B, Hypoglycemia, is not a common adverse effect of Valsartan. - Option C, Bradycardia, is not typically associated with Valsartan use. - Option D, Hypercalcemia, is not a known adverse effect of Valsartan; instead, Valsartan can lead to hyperkalemia.
3. A healthcare provider is preparing to administer Belimumab to a client with Systemic Lupus Erythematosus. Which of the following actions should the healthcare provider plan to take?
- A. Warm the medication to room temperature before administering.
- B. Administer the medication by IV bolus over 5 minutes.
- C. Dilute the medication in a 5% dextrose and water solution.
- D. Monitor the client for hypersensitivity reactions.
Correct answer: D
Rationale: Correct Answer: Monitoring the client for hypersensitivity reactions is crucial when administering Belimumab due to its known potential for severe infusion reactions and anaphylaxis. The healthcare provider should closely observe the client during the administration to promptly identify and manage any hypersensitivity reactions that may occur. Choice A is incorrect because warming Belimumab is not necessary before administration. Choice B is incorrect as Belimumab should not be administered as an IV bolus over 5 minutes; it should be given as an IV infusion over a longer duration. Choice C is incorrect as Belimumab should not be diluted in a 5% dextrose and water solution.
4. A client with a new prescription for an antihypertensive medication is being provided discharge instructions by a nurse. Which of the following statements should the nurse give?
- A. Be sure to limit your potassium intake while taking the medication.
- B. You should check your blood pressure every 8 hours while taking this medication.
- C. Your medication dosage will be increased if you develop tachycardia.
- D. Change positions slowly when you move from sitting to standing.
Correct answer: D
Rationale: The correct statement for the nurse to provide is to instruct the client to change positions slowly when moving from sitting to standing. This is crucial because antihypertensive medications can cause orthostatic hypotension, leading to dizziness or lightheadedness when changing positions quickly. Checking blood pressure every 8 hours is unnecessary and could lead to over-monitoring. There is no direct relationship between the medication and potassium intake. Increasing the medication dosage due to tachycardia is not a typical response and may not be accurate.
5. When administering Lithium to a patient, what is a life-threatening side effect?
- A. Erythema
- B. Pancreatitis
- C. Seizures
- D. Headache
Correct answer: C
Rationale: When a patient is being treated with Lithium, a life-threatening side effect to watch out for is seizures. Lithium can lower the seizure threshold, increasing the risk of seizures. Seizures are serious and necessitate prompt medical intervention to ensure the patient's safety and well-being. Erythema, which is redness of the skin, is not a common life-threatening side effect of Lithium. Pancreatitis can be a side effect of Lithium, but it is not typically life-threatening. Headache is a common side effect of Lithium, but it is not considered life-threatening.
