A nurse is caring for a client who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Available is heparin 25,000 units in 500 mL DSW. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["24"]
To calculate the infusion rate, use the formula:
(rate in mL/hr) = (desired dose in units/hr) / (available dose in units/mL)
In this case, the desired dose is 1,200 units/hr and the available dose is 25,000 units / 500 mL = 50 units/mL. Therefore,
(rate in mL/hr) = (1,200 units/hr) / (50 units/mL) = 24 mL/hr
Round the answer to the nearest tenth/whole number and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 24 mL/hr.

Correct Answer is B
Explanation
The correct answer is B
Choice B reason: Intermittent claudication
Intermittent claudication is a characteristic symptom of PAD in the early stage, due to the reduced blood flow to the muscles during exercise. It is a cramping pain in the legs that occurs with walking and is relieved by rest.
Choice A reason: Dependent rubor is a sign of PAD in the advanced stage, due to the impaired vasodilation and reactive hyperemia. It is a reddish color of the lower extremities that occurs when they are lowered and disappears when they are elevated.
Choice C reason: Foot ulcers are a complication of PAD in the late stage, due to the poor wound healing and tissue necrosis. They are usually located on the toes, heels, or pressure points.
Choice D reason: Rest pain is another sign of PAD in the late stage, due to the severe ischemia and nerve damage. It is a persistent pain in the feet or toes that occurs at night and is not relieved by rest.
Correct Answer is D
Explanation
The nurse should check the client's vital signs first because nausea and weakness are signs of digoxin toxicity, which can also cause bradycardia, hypotension, and arrhythmias. The nurse should also assess the client's serum digoxin level, potassium level, and electrocardiogram.
Request a dietitian consult is wrong because it is not the priority action and it does not address the possible cause of the client's symptoms. A dietitian consult may be helpful to provide nutritional education and guidance, but only after ruling out or treating digoxin toxicity.
Suggest that the client rests before eating the meal is wrong because it is not the priority action and it may delay the diagnosis and treatment of digoxin toxicity. The nurse should not assume that the client's symptoms are due to fatigue or lack of appetite, but rather investigate for any underlying problems.
Request an order for an antiemetic is wrong because it is not the priority action and it may mask the symptoms of digoxin toxicity. The nurse should not administer any medications that could interact with digoxin or worsen its effects, but rather notify the provider and follow the protocol for digoxin toxicity management.
