1. 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?
- A. Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level.
- B. I will call the provider to get a prescription for discontinuing the IV heparin today.
- C. Both heparin and warfarin work together to dissolve the clots.
- D. The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay.
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.
2. A client has a new prescription for Allopurinol. Which of the following instructions should the nurse include?
- A. Take this medication at bedtime.
- B. Increase your fluid intake.
- C. Avoid foods high in calcium.
- D. Take this medication with meals.
Correct answer: B
Rationale: Allopurinol can cause kidney stones due to the formation of uric acid crystals, so it is crucial for the client to increase their fluid intake. Adequate hydration helps to prevent the formation of kidney stones by diluting the urine and promoting the excretion of uric acid. Therefore, advising the client to increase their fluid intake is essential in preventing this adverse effect while taking Allopurinol.
3. When starting therapy with raloxifene, a client should monitor for which of the following adverse effects?
- A. Leg cramps
- B. Hot flashes
- C. Urinary frequency
- D. Hair loss
Correct answer: B
Rationale: The correct answer is B: Hot flashes. When initiating therapy with raloxifene, clients should be advised to monitor for hot flashes as they are a common adverse effect associated with this medication. Hot flashes are a well-known side effect of raloxifene due to its action on estrogen receptors. Leg cramps (Choice A), urinary frequency (Choice C), and hair loss (Choice D) are not typically associated with raloxifene therapy. Therefore, monitoring for hot flashes is crucial to manage and address this common side effect appropriately.
4. A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Hypokalemia potentiates the effects of Digoxin, making the heart more sensitive to its toxic effects. Monitoring and correcting electrolyte imbalances, especially low potassium levels, are crucial to prevent adverse effects of digoxin therapy. Calcium levels do not directly influence digoxin toxicity, so choices A and B are incorrect. High potassium levels, as in choice D, are less likely to increase the risk of digoxin toxicity compared to low potassium levels.
5. A client has a new prescription for Digoxin for heart failure. Which of the following adverse effects should the client be instructed to monitor for and report to the provider?
- A. Dry cough
- B. Pedal edema
- C. Bruising
- D. Yellow-tinged vision
Correct answer: D
Rationale: Yellow-tinged vision is a potential adverse effect of digoxin, which may indicate toxicity. It is crucial for the client to report this symptom promptly to the healthcare provider to prevent any further complications. Dry cough is not typically associated with digoxin use. Pedal edema is a common symptom of heart failure, which digoxin is prescribed to manage. Bruising is not a common adverse effect of digoxin.
