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 a pulmonary artery catheter is a device that measures the pressures and flows in the heart and lungs, such as the pulmonary artery pressure, the pulmonary artery wedge pressure, the cardiac output, and the mixed venous oxygen saturation. These parameters reflect the hemodynamic status of the client, which is the balance between the cardiac output and the systemic vascular resistance.
Choice B Reason: This is incorrect because a pulmonary artery catheter does not measure spinal cord perfusion, which is the blood flow to the spinal cord. Spinal cord perfusion can be affected by spinal cord injury, spinal anesthesia, or spinal surgery.
Choice C Reason: This is incorrect because a pulmonary artery catheter does not measure renal function, which is the ability of the kidneys to filter waste products and maintain fluid and electrolyte balance. Renal function can be assessed by urine output, blood urea nitrogen, creatinine, and glomerular filtration rate.
Choice D Reason: This is incorrect because a pulmonary artery catheter does not measure intracranial pressure, which is the pressure inside the skull. Intracranial pressure can be increased by brain injury, stroke, tumor, infection, or hydrocephalus.
Correct Answer is A
Explanation
Choice A Reason: This choice is correct because allowing the drainage to drip onto a sterile gauze pad may help to identify if it is cerebrospinal fluid (CSF), which is a clear fluid that surrounds and protects the brain and spinal cord. CSF leakage from the nose (rhinorrhea) may indicate a basilar skull fracture, which is a serious injury that can cause intracranial bleeding, infection, or brain damage. The nurse should test the drainage for the presence of glucose or the halo sign, which are indicators of CSF.
Choice B Reason: This choice is incorrect because obtaining a culture of the specimen using sterile swabs may introduce bacteria into the nasal cavity and increase the risk of infection. The nurse should avoid inserting anything into the nose or mouth of a client who has a suspected basilar skull fracture.
Choice C Reason: This choice is incorrect because inserting sterile packing into the nares may increase the pressure in the cranial cavity and worsen the injury. The nurse should avoid applying pressure or occluding the nose or ears of a client who has a suspected basilar skull fracture.
Choice D Reason: This choice is incorrect because suctioning the nose gently with a bulb syringe may damage the nasal mucosa and cause bleeding. The nurse should avoid suctioning or irrigating the nose or ears of a client who has a suspected basilar skull fracture.
