1. A client has a new prescription for Warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider immediately?

Correct answer: A

Rationale: An INR of 4.0 is above the therapeutic range for a client on Warfarin, indicating an increased risk of bleeding. This finding requires immediate reporting to the provider for appropriate intervention to prevent complications associated with excessive anticoagulation. Potassium, sodium, and creatinine levels are within normal ranges and are not directly related to the risk of bleeding in a client on Warfarin therapy.

2. A client has a new prescription for Nitroglycerin to treat angina. Which of the following instructions should be included?

Correct answer: C

Rationale: When using Nitroglycerin patches to treat angina, it is crucial to apply the patch to a different site each time. This practice helps prevent skin irritation and ensures proper absorption of the medication, optimizing its effectiveness in managing angina symptoms.

3. A client has a prescription for Levothyroxine. Which of the following instructions should the nurse include?

Correct answer: A

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, leading to reduced effectiveness of the medication.

4. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

5. A client with deep vein thrombosis has been on heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?

Correct answer: A

Rationale: The correct answer is A because warfarin takes several days to reach a therapeutic level and exert its full anticoagulant effect. During this time, the IV heparin is continued to prevent clotting until the warfarin is effective. Both medications are used together temporarily for this reason. Discontinuing heparin prematurely can increase the risk of clot formation. Therefore, the nurse should explain to the client that the IV heparin will be continued until the warfarin reaches a therapeutic level.
