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 A
Explanation
Choice A Reason: This is correct because dopamine is a vasopressor that increases the contractility and stroke volume of the heart, which results in an increased systolic blood pressure.
Choice B Reason: This is incorrect because dopamine can cause tachycardia as a side effect, but this does not indicate a therapeutic effect. An increased radial heart rate can also indicate other conditions, such as anxiety, fever, or dehydration.
Choice C Reason: This is incorrect because dopamine does not reduce cardiac output, but rather increases it by improving the pumping function of the heart.
Choice D Reason: This is incorrect because dopamine does not reduce urine output, but rather increases it by stimulating the renal blood vessels and enhancing renal perfusion.
Correct Answer is C
Explanation
Choice A Reason: Albumin 25% is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Albumin 25% is a colloid solution that increases the oncotic pressure and draws fluid from the interstitial space into the intravascular space, which can worsen the intracranial pressure by increasing the cerebral blood flow and edema.
Choice B Reason: Dextran 70 is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Dextran 70 is a plasma expander that increases the blood volume and viscosity, which can also worsen the intracranial pressure by increasing the cerebral blood flow and edema.
Choice C Reason: Mannitol 25% is a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Mannitol 25% is an osmotic diuretic that reduces the intracranial pressure by creating an osmotic gradient and drawing fluid from the brain tissue into the blood vessels, which can then be excreted by the kidneys. The nurse should monitor the urine output, serum osmolality, and electrolytes when administering mannitol 25%.
Choice D Reason: Hydroxyethyl starch is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Hydroxyethyl starch is another plasma expander that has similar effects as dextran 70, and can also increase the risk of coagulopathy and renal failure.
