1. A client with a history of deep vein thrombosis is prescribed warfarin. The nurse should monitor for which potential adverse effect?
- A. Increased risk of bleeding
- B. Decreased risk of bleeding
- C. Increased risk of infection
- D. Decreased risk of infection
Correct answer: A
Rationale: The correct answer is A: Increased risk of bleeding. Warfarin is an anticoagulant medication that works by prolonging the time it takes for blood to clot. Therefore, a potential adverse effect of warfarin is an increased risk of bleeding. It is crucial for the nurse to monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, nosebleeds, or blood in the urine or stool. Monitoring for these signs is essential to prevent serious complications associated with excessive bleeding. Choices B, C, and D are incorrect because warfarin does not decrease the risk of bleeding, increase the risk of infection, or decrease the risk of infection. The primary concern with warfarin therapy is the potential for bleeding complications, so close monitoring for signs of bleeding is essential.
2. The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?
- A. Hyponatremia
- B. Hypernatremia
- C. Hyperkalemia
- D. Hypokalemia
Correct answer: D
Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.
3. A client with a history of heart failure is prescribed spironolactone. The nurse should monitor for which potential side effect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hyponatremia
- D. Hypernatremia
Correct answer: A
Rationale: The correct answer is A: Hyperkalemia. Spironolactone is a potassium-sparing diuretic, which can lead to an excess of potassium in the body, causing hyperkalemia. This medication inhibits the action of aldosterone, leading to decreased potassium excretion and potential retention. Monitoring potassium levels is essential to prevent complications such as cardiac arrhythmias, especially in clients with heart failure.
4. A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
- A. Advise the client that the effects of the medication have worn off
- B. Explain that the medication is not given to relieve pain
- C. Check for the correct placement of the patch on the client
- D. Offer to apply a new transdermal patch to address the pain
Correct answer: B
Rationale: The correct answer is B. Scopolamine is not a pain medication; it is commonly used to prevent nausea and vomiting, particularly in surgical settings. It works on the central nervous system to help control these symptoms, not to relieve pain. Therefore, it is important for the nurse to explain to the client that the medication is not intended to relieve pain but rather to manage other specific symptoms. Checking the correct placement of the patch is also important to ensure proper administration, but addressing the misconception about the medication's purpose is the priority in this scenario. Offering to apply a new patch would not address the client's pain as scopolamine is not meant for pain relief. Advising the client that the effects have worn off is inaccurate because the medication is not used for pain management.
5. A client is prescribed an antibiotic for a urinary tract infection (UTI). What instruction should the practical nurse provide to the client to ensure the effectiveness of the medication?
- A. Take the medication with food.
- B. Increase fluid intake.
- C. Complete the full course of the medication.
- D. Avoid dairy products.
Correct answer: C
Rationale: The practical nurse should instruct the client to complete the full course of the antibiotic to ensure the infection is fully treated and to prevent the development of antibiotic resistance. Completing the full course of antibiotics helps to eradicate the infection completely and reduces the risk of bacteria developing resistance to the medication. Choices A, B, and D are not directly related to ensuring the effectiveness of the antibiotic. While taking medication with food or increasing fluid intake can be beneficial in general, the crucial instruction in this case is to complete the full course of the antibiotic.
