1. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?
- A. Continue taking warfarin until the day of surgery.
- B. Stop taking warfarin three days before surgery.
- C. Switch to aspirin before surgery.
- D. Stop taking warfarin one week before surgery.
Correct answer: D
Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.
2. The nurse is administering sevelamer (RenaGel) during lunch to a client with end-stage renal disease (ESRD). The client asks the nurse to bring the medication later. The nurse should describe which action of RenaGel as an explanation for taking it with meals?
- A. Prevents indigestion associated with the ingestion of spicy foods.
- B. Binds with phosphorus in foods and prevents absorption.
- C. Promotes stomach emptying and prevents gastric reflux.
- D. Buffers hydrochloric acid and prevents gastric erosion.
Correct answer: B
Rationale: Sevelamer (RenaGel) binds with phosphorus in foods and prevents its absorption. By taking RenaGel with meals, the binding of phosphorus helps to reduce the phosphorus load absorbed from food, thus aiding in the management of hyperphosphatemia in clients with ESRD.
3. For a patient with asthma, what is the primary purpose of prescribing montelukast?
- A. Relieve acute bronchospasm
- B. Prevent asthma attacks
- C. Thin respiratory secretions
- D. Suppress cough
Correct answer: B
Rationale: Montelukast, a leukotriene receptor antagonist, is primarily prescribed to prevent asthma attacks. It works by reducing inflammation and bronchoconstriction in the airways, thereby helping to control asthma symptoms and prevent exacerbations.
4. A client with newly diagnosed diabetes mellitus is being discharged home. Which statement indicates the client understands the instructions about managing blood glucose levels?
- A. I will test my blood glucose level once a week.
- B. I should eat a snack if my blood glucose is 70 mg/dl.
- C. If I feel shaky, I should take another dose of insulin.
- D. It's okay to skip a meal if I'm not hungry.
Correct answer: B
Rationale: Choice B is the correct answer. Eating a snack when blood glucose is low (70 mg/dl) can help prevent hypoglycemia. It is important for clients with diabetes to manage their blood glucose levels to prevent complications, and consuming a snack when glucose levels drop can help maintain the balance.
5. A patient with epilepsy is prescribed phenytoin. What is the primary side effect the nurse should monitor for?
- A. Hypotension
- B. Gingival hyperplasia
- C. Bradycardia
- D. Hyperkalemia
Correct answer: B
Rationale: Gingival hyperplasia, or overgrowth of the gums, is a common side effect of phenytoin. Patients should maintain good oral hygiene to minimize this effect.
