1. When should a blood sample be obtained for a peak serum level of gentamicin when administered by IV infusion for 1 hour at 0900?

A. 1000
B. 1030
C. 1100
D. 1130

Correct answer: B

Rationale: The nurse should obtain the blood sample for the peak serum level at 1030. This timing allows for 30 minutes to elapse after the completion of the 1-hour IV infusion, which is the recommended window for obtaining the peak serum level of gentamicin.

2. Which of the following is not a side effect of the vasodilator Nifedipine?

A. Nausea
B. Flushed appearance
C. Vertigo
D. Sexual dysfunction

Correct answer: D

Rationale: Sexual dysfunction is not a common side effect of vasodilators such as Nifedipine. Nausea, flushed appearance, and vertigo are more commonly reported side effects associated with this medication. It's essential for healthcare providers to be aware of the potential side effects to monitor and manage them effectively in patients prescribed with Nifedipine.

3. Which drug class has been found to decrease mortality if given within 8 hours of an MI due to a decrease in cardiac workload?

A. Antiplatelets
B. Beta-adrenergic blockers
C. ACE inhibitors
D. Calcium channel blockers

Correct answer: B

Rationale: Beta-adrenergic blockers have been shown to decrease mortality when administered within 8 hours of a myocardial infarction (MI). They do so by reducing cardiac workload, which helps improve outcomes post-MI. These drugs work by blocking the effects of adrenaline on the heart, leading to decreased heart rate, blood pressure, and myocardial oxygen demand, thereby protecting the heart muscle from further damage. This makes them a crucial part of the treatment regimen for acute coronary syndromes like MI.

4. Medications classified as angiotensin II receptor agents typically end in?

A. Sartan
B. Ase
C. Olol
D. Pril

Correct answer: A

Rationale: Angiotensin II receptor agents belong to the drug class called angiotensin II receptor blockers (ARBs). The generic names of ARBs usually end in -sartan, helping to identify this specific class of medications. Therefore, medications that end in -sartan are likely to be angiotensin II receptor agents. Choices B, C, and D are incorrect because drugs ending in -ase (like streptokinase), -olol (like propranolol), and -pril (like lisinopril) typically belong to different drug classes with distinct mechanisms of action.

5. A client is receiving treatment with capecitabine. Which of the following findings should the nurse monitor?

A. Hyperglycemia
B. Hypocalcemia
C. Neutropenia
D. Bradycardia

Correct answer: C

Rationale: The nurse should monitor the client for neutropenia when receiving capecitabine, as it is a common adverse effect caused by bone marrow suppression. Neutropenia increases the risk of infection, making it essential for the nurse to closely monitor the client's white blood cell count and assess for signs of infection during treatment. Hyperglycemia (Choice A) is not typically associated with capecitabine. Hypocalcemia (Choice B) and bradycardia (Choice D) are not commonly linked to capecitabine use. Therefore, monitoring for neutropenia is the priority in this scenario.
