Nursing Elites

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 is receiving daily doses of Oprelvekin. Which of the following laboratory values should be monitored to determine the effectiveness of this medication?

• A. Hemoglobin
• B. Absolute neutrophil count
• C. Platelet count
• D. Total white blood cell count

Correct answer: C

Rationale: Oprelvekin is a medication that stimulates platelet production. Therefore, monitoring the platelet count is essential to assess the effectiveness of this drug. The expected outcome for oprelvekin therapy is a platelet count greater than 50,000/mm^3. Changes in platelet count can indicate the response to the medication and help in adjusting the treatment plan accordingly. Monitoring hemoglobin, absolute neutrophil count, or total white blood cell count is not directly related to the mechanism of action of Oprelvekin and therefore would not provide accurate information on the drug's effectiveness.

3. A client is taking atorvastatin for hyperlipidemia. Which of the following findings should the nurse report to the provider immediately?

• A. Headache
• B. Nausea
• C. Muscle pain
• D. Diarrhea

Correct answer: C

Rationale: Muscle pain should be reported immediately as it can indicate rhabdomyolysis, a severe adverse effect of atorvastatin. Rhabdomyolysis is characterized by muscle pain, weakness, and can lead to serious complications such as kidney damage, making it crucial for the nurse to notify the provider promptly. Headache, nausea, and diarrhea are common side effects of atorvastatin and do not require immediate reporting unless severe or persistent.

4. A client with increased intracranial pressure is receiving Mannitol. Which finding should the nurse report to the provider?

• A. Blood glucose 150 mg/dL
• B. Urine output 40 mL/hr
• C. Dyspnea
• D. Bilateral equal pupil size

Correct answer: C

Rationale: The correct answer is C: Dyspnea. Dyspnea is a concerning finding in a client receiving Mannitol as it can be a manifestation of heart failure, which is an adverse effect of the medication. The nurse should promptly notify the provider, discontinue the Mannitol, and initiate appropriate interventions to address the dyspnea and monitor the client's condition closely. Choice A, Blood glucose of 150 mg/dL, is within normal limits and not directly related to Mannitol administration. Choice B, Urine output of 40 mL/hr, could indicate decreased renal perfusion, but it is not the most critical finding compared to dyspnea. Choice D, Bilateral equal pupil size, is a normal neurological finding and not directly related to Mannitol therapy.

5. What is one of the therapeutic uses of Valproate?

• A. Suppression of seizure activity
• B. Replacement of hypothyroidism to restore normal hormone balance
• C. Maintenance of blood glucose
• D. Lowering of blood pressure

Correct answer: A

Rationale: Valproate, also known as Valproic acid, is commonly used in medicine for the suppression of seizure activity. It is an anticonvulsant medication that helps manage and prevent seizures in various conditions such as epilepsy. While it is not used for replacing hypothyroidism, maintaining blood glucose levels, or lowering blood pressure, its primary therapeutic use is in managing seizures.
