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 D
Explanation
Choice A Reason: This is incorrect because cognitive impairment that decreases over several months post-injury is more likely to occur in a client who has a diffuse axonal injury, which is a widespread damage to the brain's white mater.
Choice B Reason: This is incorrect because neurologic deficits that increase up to 2 weeks post-injury are more likely to occur in a client who has a subdural hematoma, which is a collection of blood between the dura and the arachnoid membranes.
Choice C Reason: This is incorrect because a change in the level of consciousness that develops over 48 hr is more likely to occur in a client who has an intracerebral hematoma, which is a collection of blood within the brain tissue.
Choice D Reason: This is correct because a lucid period followed by an immediate loss of consciousness is a typical manifestation of an epidural hematoma, which is a collection of blood between the skull and the dura. The lucid period occurs when the initial bleeding stops and the client regains consciousness. The immediate loss of consciousness occurs when the bleeding resumes and causes increased intracranial pressure.
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.
