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 C
Explanation
Choice A Reason: This is incorrect because hypervolemia is a condition of excess fluid volume in the body. A client who has an extensive burn injury is more likely to have hypovolemia, which is a condition of low fluid volume, due to fluid loss from the damaged skin and capillaries.
Choice B Reason: This is incorrect because metabolic alkalosis is a condition of high blood pH and high bicarbonate level. A client who has an extensive burn injury is more likely to have metabolic acidosis, which is a condition of low blood pH and low bicarbonate level, due to increased production of lactic acid and ketones from tissue hypoxia and breakdown.
Choice C Reason: This is correct because low hemoglobin is a common laboratory finding in a client who has an extensive burn injury. Hemoglobin is the protein in red blood cells that carries oxygen. A client who has an extensive burn injury may have low hemoglobin due to hemolysis, which is the destruction of red blood cells, or hemorrhage, which is the loss of blood.
Choice D Reason: This is incorrect because hyperkalemia is a condition of high blood potassium level. A client who has an extensive burn injury may have hyperkalemia in the early phase of injury, due to cell damage and potassium release, but it is usually transient and followed by hypokalemia, which is a condition of low blood potassium level, due to fluid loss and potassium depletion.
Correct Answer is ["B","D","E"]
Explanation
Choice A Reason: This choice is incorrect because headache is not a common manifestation of ARF. Headache may be caused by various factors such as dehydration, stress, sinusitis, or migraine, but it does not indicate ARF.
Choice B Reason: This choice is correct because severe dyspnea is a common manifestation of ARF. Dyspnea is a difficulty or discomfort in breathing that affects the oxygen delivery and carbon dioxide removal from the body. It may be caused by various factors such as lung disease, heart disease, anemia, or anxiety, but it indicates ARF when it is severe and persistent.
Choice C Reason: This choice is incorrect because nausea is not a common manifestation of ARF. Nausea is a sensation of uneasiness or discomfort in the stomach that may precede vomiting. It may be caused by various factors such as food poisoning, motion sickness, medication side effects, or pregnancy, but it does not indicate ARF.
Choice D Reason: This choice is correct because hypotension is a common manifestation of ARF. Hypotension is a condition in which the blood pressure is lower than normal (less than 90/60 mm Hg). It may be caused by various factors such as dehydration, blood loss, sepsis, or shock, but it indicates ARF when it is due to reduced cardiac output or vasodilation from hypoxia.
Choice E Reason: This choice is correct because decreased level of consciousness is a common manifestation of ARF. Decreased level of consciousness is a condition in which the person has impaired awareness or responsiveness to stimuli. It may be caused by various factors such as brain injury, stroke, seizure, or drug overdose, but it indicates ARF when it is due to increased carbon dioxide levels (hypercapnia) or decreased oxygen levels (hypoxemia) in the brain.
