A nurse is preparing to administer medications to four clients. The nurse should administer medications to which of the following clients first?

A client who is post-coronary artery bypass graft (CABG), has total cholesterol of 318 mg/dL, and is prescribed atorvastatin

A client who has pneumonia, a WBC count of 11,500/mm³, and is prescribed piperacillin

A client who has renal failure, a serum potassium of 5.8 mEq/L, and is prescribed sodium polystyrene sulfonate

A client who has anemia, hemoglobin of 11 g/dL, and is prescribed epoetin alfa

Answer and Explanation

The Correct Answer is C

Choice A Reason: This is incorrect because a client who is post-CABG and has high cholesterol is not in immediate danger, as atorvastatin is a long-term medication that lowers cholesterol and prevents cardiovascular complications.

Choice B Reason: This is incorrect because a client who has pneumonia and a slightly elevated WBC count is not in immediate danger, as piperacillin is an antibiotic that treats bacterial infections.

Choice C Reason: This is correct because a client who has renal failure and a high serum potassium level is in immediate danger, as sodium polystyrene sulfonate is an emergency medication that lowers potassium and prevents cardiac arrhythmias.

Choice D Reason: This is incorrect because a client who has anemia and a mild hemoglobin deficiency is not in immediate danger, as epoetin alfa is a long-term medication that stimulates red blood cell production and improves oxygen delivery.

Correct Answer is B

Explanation

Choice A Reason: This choice is incorrect because administering a vasodilator medication may lower the blood pressure and worsen the cerebral perfusion. A vasodilator medication is a drug that relaxes the blood vessels and reduces the resistance to blood ﬂow. It may be used for clients who have hypertension, angina, or heart failure, but it does not help to reduce the intracranial pressure (ICP).

Choice B Reason: This choice is correct because elevating the head of the bed to 30° may help to improve the venous drainage and decrease the ICP. ICP is the pressure exerted by the brain tissue, cerebrospinal ﬂuid (CSF), and blood within the cranial cavity. A normal ICP range is 5 to 15 mm Hg, and an elevated ICP (>20 mm Hg) can cause cerebral ischemia, herniation, or death. Therefore, positioning the client in a semi-Fowler's position (30° angle) or high- Fowler's position (60° to 90° angle) can facilitate breathing and prevent further complications.

Choice C Reason: This choice is incorrect because applying a cold compress to the forehead may cause vasoconstriction and increase the ICP. A cold compress is a device that applies cold temperature to a body part to reduce inﬂammation, pain, or swelling. It may be used for clients who have headaches, sprains, or bruises, but it does not help to reduce the ICP.

Choice D Reason: This choice is incorrect because decreasing the oxygen ﬂow rate may cause hypoxia and worsen the cerebral ischemia. Hypoxia is a condition in which the body or a part of it does not receive enough oxygen. It may cause symptoms such as confusion, agitation, or cyanosis. Therefore, providing adequate oxygenation and ventilation is essential to maintain the brain function and prevent further damage.

Correct Answer is ["167 "]

Explanation

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.
