A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?
- A. Platelet count
- B. Prothrombin time (PT)
- C. White blood cell count
- D. Hemoglobin level
Correct Answer: B
Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

A young male client is admitted to rehabilitation following a right above-knee amputation (AKA) and reports aching in his right foot. Which intervention is most important for the nurse to implement?
- A. Encourage discussion about feelings of limb loss.
- B. Administer a prescription for gabapentin.
- C. Teach the client how to wrap the stump with an elastic bandage.
- D. Offer assistance to move to a quiet room to relax.
Correct Answer: B
Rationale: The correct answer is B: Administer a prescription for gabapentin. Gabapentin is used to treat phantom limb pain, which is common after amputations. Encouraging discussion about feelings of limb loss (choice A) is important for emotional support but does not address the physical pain. Teaching the client how to wrap the stump with an elastic bandage (choice C) is not indicated for aching in the 'right foot' as described. Offering assistance to move to a quiet room to relax (choice D) may provide comfort but does not address the underlying issue of phantom limb pain.
A client with a urinary tract infection (UTI) is prescribed ciprofloxacin. What client teaching is essential?
- A. Increase fluid intake to prevent crystalluria.
- B. Take the medication with meals to prevent GI upset.
- C. Avoid sunlight exposure while taking the medication.
- D. Report any changes in the color of urine.
Correct Answer: A
Rationale: The correct answer is to increase fluid intake to prevent crystalluria, a potential side effect of ciprofloxacin. Crystalluria is the formation of crystals in the urine, which can be reduced by maintaining adequate hydration. Choice B is incorrect because ciprofloxacin can be taken with or without food. Choice C is incorrect as avoiding sunlight exposure is more relevant for medications that cause photosensitivity, not typically a concern with ciprofloxacin. Choice D is less essential than choice A because while reporting changes in urine color is important, preventing crystalluria through adequate fluid intake is a higher priority.
A client with deep vein thrombosis (DVT) is prescribed heparin therapy. What laboratory value should the nurse monitor?
- A. Monitor the client's liver function tests.
- B. Monitor the client's prothrombin time (PT).
- C. Monitor the client's partial thromboplastin time (PTT).
- D. Monitor the client's red blood cell count.
Correct Answer: C
Rationale: The correct answer is C: Monitor the client's partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.
A client with Parkinson's disease is prescribed levodopa/carbidopa. The nurse instructs the client to take the medication with meals. Which rationale should the nurse provide for taking the medication with food?
- A. It enhances the effectiveness of the medication
- B. It helps to improve absorption
- C. It prevents orthostatic hypotension
- D. It reduces gastrointestinal upset
Correct Answer: D
Rationale: The correct answer is D: 'It reduces gastrointestinal upset.' Levodopa/carbidopa can cause nausea and other gastrointestinal side effects. Taking the medication with food can help reduce these side effects and improve the client's comfort. Choices A, B, and C are incorrect because taking the medication with food does not primarily enhance effectiveness, improve absorption, or prevent orthostatic hypotension. The main reason for advising to take the medication with meals is to minimize gastrointestinal upset.
A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?
- A. Administer IV calcium gluconate.
- B. Administer sodium polystyrene sulfonate (Kayexalate).
- C. Administer insulin with dextrose.
- D. Restrict potassium intake in the client's diet.
Correct Answer: A
Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.
