A nurse is preparing to administer digoxin at a dosage of 8 mcg/kg/day orally, divided equally every 12 hours, to a preschooler who weighs 33 lbs. Digoxin elixir is available at a concentration of 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Instructing the client to perform range-of-motion exercises to his lower extremities immediately after cardiac catheterization is not recommended. The client should maintain bed rest with the affected leg straight to prevent bleeding from the catheter insertion site.

Choice B reason: Ambulating the client 1 hour following the procedure is not advised. After femoral artery access, the client is typically required to remain on bed rest with the affected leg straight for several hours to ensure hemostasis and prevent bleeding².

Choice C reason: Restricting the client's fluid intake is not a standard post-procedure action. Adequate hydration is important after cardiac catheterization to help flush the contrast dye used during the procedure from the body, unless contraindicated.

Choice D reason: Assessing the color, temperature, and pulse in the affected extremity is crucial for detecting signs of bleeding, hematoma formation, or arterial occlusion. These assessments should be performed regularly as part of post-cardiac catheterization care².

Choice A reason: Atropine is not typically used for the treatment of pulmonary embolism. It is an anticholinergic drug that is primarily used to treat bradycardia (slow heart rate) and as part of the management of organophosphate poisoning. It does not have a role in the management of pulmonary embolism, which requires anticoagulation to prevent further clot formation.

Choice B reason: Furosemide is a loop diuretic commonly used to treat fluid overload conditions such as heart failure or edema. While it can help relieve symptoms associated with fluid accumulation, it does not treat the underlying cause of a pulmonary embolism, which is a blood clot in the pulmonary arteries.

Choice C reason: Heparin is an anticoagulant medication that is commonly used in the initial treatment of pulmonary embolism. It works by preventing the formation of new blood clots and stopping existing clots from getting bigger. Heparin is often administered intravenously or subcutaneously and is a key component in the management of pulmonary embolism.

Choice D reason: Dexamethasone is a corticosteroid that is used to reduce inflammation in various conditions, such as allergic reactions, asthma, and certain types of arthritis. It is not used as a primary treatment for pulmonary embolism, as it does not have anticoagulant properties.
