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 B
Explanation
Choice A Reason: This is incorrect because the client is not in deep coma, as the Glasgow Coma Scale (GCS) score ranges from 3 to 15, with 3 being the lowest possible score and indicating deep coma or death.
Choice B Reason: This is correct because the client needs total nursing care, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may only open his eyes to pain, make incomprehensible sounds, and have abnormal flexion to pain.
Choice C Reason: This is incorrect because the client is not alert and oriented, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may not be able to follow commands, answer questions, or recognize people or places.
Choice D Reason: This is incorrect because the client is not responding to verbal stimuli, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may only respond to painful stimuli, such as pinching or squeezing.
