A nurse is reviewing the medication list for a client who has a new prescription for warfarin. The nurse should recognize which is incompatible with warfarin?
Vitamin A
Alprazolam
Vitamin K
Furosemide
The Correct Answer is C
A) Vitamin A: While vitamin A can affect various bodily functions, it is not known to have a direct interaction with warfarin. Therefore, it is not considered incompatible with warfarin therapy.
B) Alprazolam: This medication, a benzodiazepine, is primarily used to treat anxiety and does not have a significant interaction with warfarin. Thus, it is not incompatible with warfarin therapy.
C) Vitamin K: This vitamin is a critical consideration when a client is on warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, so an increased intake of vitamin K can counteract the effects of warfarin, making this the correct answer. Clients on warfarin should maintain a consistent intake of vitamin K to prevent fluctuations in their INR levels.
D) Furosemide: This loop diuretic is used to manage conditions such as heart failure and edema. While it may affect electrolyte levels, it does not have a direct interaction that would render it incompatible with warfarin. It can be safely used alongside warfarin with appropriate monitoring.

Correct Answer is C
Explanation
A) Intermittent claudication: This symptom is indicative of arterial insufficiency, not chronic venous insufficiency. Intermittent claudication is characterized by pain in the legs during activity due to insufficient blood flow, which is not typical in venous conditions.
B) Decreased pedal pulses: In chronic venous insufficiency, pedal pulses are usually normal. Decreased pedal pulses suggest arterial disease, where blood flow is compromised. Thus, this finding would not be expected in a client with venous insufficiency.
C) Bronze/brown discoloration of the skin: This is a hallmark finding in chronic venous insufficiency. The discoloration occurs due to the deposition of hemosiderin from the breakdown of red blood cells, which is a result of prolonged venous stasis and chronic edema, particularly around the lower extremities.
D) Cool skin temperature: Skin temperature in chronic venous insufficiency is typically warm due to increased blood flow and stasis in the veins. Cool skin temperature is more characteristic of arterial insufficiency, where blood supply is reduced and can lead to cooler extremities.
E) Full screen mode is in effect during your proctored testing: This statement is irrelevant to the clinical assessment of chronic venous insufficiency and serves no purpose in understanding the client’s condition. It does not contribute to the assessment findings.
Correct Answer is D
Explanation
A) Blood pressure 102/76: While this blood pressure reading is on the lower side, it does not typically warrant withholding carvedilol unless the client exhibits symptoms of hypotension, such as dizziness or fainting. Carvedilol is an antihypertensive, but the reading itself is not critically low enough to necessitate holding the medication.
B) Temperature of 100.3 F: A mild fever at this temperature does not directly relate to carvedilol administration. It may indicate an underlying infection or inflammation, but it is not a contraindication for administering the medication. Monitoring the client’s temperature is important, but it does not require notifying the healthcare provider in this context.
C) Respiratory rate 10: A respiratory rate of 10 breaths per minute indicates bradypnea, which can be concerning. However, it is not the primary reason to withhold carvedilol unless the client shows significant respiratory distress. Monitoring is essential, but the decision to withhold the medication would depend on the overall clinical picture.
D) Heart rate of 49: A heart rate of 49 bpm is considered bradycardia and is a significant concern when administering carvedilol, a beta-blocker that can further decrease heart rate. It is essential to hold the medication and notify the healthcare provider, as this bradycardia could lead to potential adverse effects or complications. Monitoring the client's heart rate is crucial in managing their medication safely.
