A nurse is caring for a client who has a pulmonary embolism and has a new prescription for enoxaparin 1.5 mg/kg/dose subcutaneously every 12 hours. The client weighs 245 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["167 "]
To calculate the dose of enoxaparin, follow these steps:
1) Convert the client's weight from pounds to kilograms:
245 lbs / 2.2046 (kg/lb) = 111.13 kg (rounded to the nearest whole number, it's 111 kg).
2) Multiply the weight in kilograms by the prescribed dose per kilogram:
111 kg x 1.5 mg/kg = 166.5 mg.
Round the answer to the nearest whole number, so the nurse should administer 167 mg per dose of enoxaparin every 12 hours to the client with a pulmonary embolism.

Correct Answer is B
Explanation
Choice A Reason: This choice is incorrect because furosemide is a diuretic that helps to reduce fluid retention and edema. It may be used for clients who have heart failure or hypertension, but it does not treat pulmonary embolism.
Choice B Reason: This choice is correct because heparin is an anticoagulant that helps to prevent blood clots from forming or growing larger. It may be used for clients who have pulmonary embolism, which is a blockage of a pulmonary artery by a blood clot that usually originates from a deep vein thrombosis (DVT). Heparin can reduce the risk of complications such as pulmonary infarction or death.
Choice C Reason: This choice is incorrect because dexamethasone is a corticosteroid that helps to reduce inflammation and immune response. It may be used for clients who have allergic reactions, asthma, or autoimmune diseases, but it does not treat pulmonary embolism.
Choice D Reason: This choice is incorrect because epinephrine is a sympathomimetic that helps to stimulate the heart and blood vessels. It may be used for clients who have cardiac arrest, anaphylaxis, or severe asthma, but it does not treat pulmonary embolism.
Choice E Reason: This choice is incorrect because atropine is an anticholinergic that helps to block the effects of acetylcholine on the heart and smooth muscles. It may be used for clients who have bradycardia, atrioventricular block, or organophosphate poisoning, but it does not treat pulmonary embolism.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because magnesium 2.5 mEq/L is a normal value and does not indicate an increased risk of AKI. Magnesium is an electrolyte that plays a role in muscle and nerve function, blood pressure regulation, and energy production. The normal range for magnesium is 1.5 to 2.5 mEq/L.
Choice B Reason: This is incorrect because serum osmolality 290 mOsm/kg H2O is a normal value and does not indicate an increased risk of AKI. Serum osmolality is a measure of the concentration of solutes in the blood, such as sodium, glucose, and urea. The normal range for serum osmolality is 275 to 295 mOsm/kg H2O.
Choice C Reason: This is incorrect because blood urea nitrogen (BUN) 20 mg/dL is a normal value and does not indicate an increased risk of AKI. BUN is a measure of the amount of urea, a waste product of protein metabolism, in the blood. The normal range for BUN is 7 to 20 mg/dL.
Choice D Reason: This is correct because serum creatinine 1.8 mg/dL is an elevated value and indicates an increased risk of AKI. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys. The normal range for serum creatinine is 0.6 to 1.2 mg/dL for women and 0.7 to 1.3 mg/dL for men. An increase in serum creatinine indicates a decrease in kidney function and glomerular filtration rate (GFR).
