1. A client has a prescription for Heparin. Which of the following laboratory tests should be monitored while the client is receiving Heparin?

A. Prothrombin time (PT)
B. Complete blood count (CBC)
C. International normalized ratio (INR)
D. Activated partial thromboplastin time (aPTT)

Correct answer: D

Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor while a client is receiving Heparin. This test is used to assess the therapeutic levels of heparin in the blood, ensuring that the dose is within the safe and effective range. Monitoring aPTT helps healthcare providers adjust the dosage of Heparin to prevent complications such as bleeding or clotting.

2. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?

A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
D. Draw a peak level at 0900 and a trough level at 2100.

Correct answer: C

Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.

3. While caring for a client on long-term aspirin therapy, the nurse should monitor the client for which of the following complications?

A. Hemorrhagic stroke
B. Thromboembolic stroke
C. Iron deficiency anemia
D. Neutropenia

Correct answer: A

Rationale: Corrected Rationale: Long-term aspirin therapy can increase the risk of hemorrhagic stroke due to its antiplatelet effects, which can lead to bleeding complications. Aspirin inhibits platelet function, potentially causing bleeding in the brain and increasing the risk of a hemorrhagic stroke. Choice B, thromboembolic stroke, is incorrect because aspirin therapy is actually used to prevent thromboembolic events by inhibiting platelet aggregation. Choices C and D, iron deficiency anemia and neutropenia, are not directly associated with long-term aspirin therapy.

4. Which of the following conditions is not treated with Ephedrine?

A. COPD
B. Hypotension
C. Congestion
D. Incontinence

Correct answer: A

Rationale: Ephedrine is not typically used to treat COPD. While it can help relieve symptoms like congestion and hypotension, it is not a first-line treatment for COPD. Incontinence is not a condition commonly treated with Ephedrine either.

5. A drug ending in the suffix (navir) is considered a ______.

A. Antidepressant
B. Protease inhibitor
C. Beta antagonist
D. H antagonist

Correct answer: B

Rationale: When a drug name ends in the suffix -navir, it indicates that the drug is a protease inhibitor. Protease inhibitors are commonly used in antiviral therapy to treat infections by inhibiting viral replication. Therefore, the correct answer is B: Protease inhibitor.
