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 nurse is teaching a client who has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?

A. Tachycardia
B. Hyperglycemia
C. Hyponatremia
D. Constipation

Correct answer: A

Rationale: Corrected Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases. Choice B, Hyperglycemia, is not a common adverse effect of Hydralazine. Choice C, Hyponatremia, and Choice D, Constipation, are also not typically associated with Hydralazine use.

3. When should a patient taking omeprazole be administered the medication?

A. Before bedtime
B. After dinner
C. In the morning on an empty stomach
D. With the patient's lunch meal

Correct answer: C

Rationale: Omeprazole should be administered in the morning on an empty stomach to maximize its effectiveness. This timing is important as omeprazole works best when taken before a meal to inhibit acid production by the stomach. Taking it on an empty stomach in the morning allows the medication to be absorbed efficiently and provides optimal therapeutic effects throughout the day. Choices A, B, and D are incorrect because taking omeprazole before bedtime, after dinner, or with lunch may not allow the medication to work effectively as it requires an empty stomach for better absorption and action.

4. What is the action of Metformin?

A. Decreasing intestinal glucose absorption
B. Increasing sensitivity to insulin
C. Decreasing hepatic glucose production
D. All of the above

Correct answer: D

Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.

5. A client reports taking Aspirin four times daily for a sprained wrist. Which of the following prescribed medications taken by the client is contraindicated with aspirin?

A. Digoxin
B. Metformin
C. Warfarin
D. Nitroglycerin

Correct answer: C

Rationale: Aspirin inhibits platelet aggregation, which can increase the effect of anticoagulants like warfarin, leading to an elevated risk of bleeding. Therefore, the concurrent use of aspirin and warfarin is generally contraindicated due to this potential interaction. Digoxin is not contraindicated with aspirin in most cases. Metformin and nitroglycerin do not have significant interactions with aspirin, making them less likely to be contraindicated in this scenario.
