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.)

Answer and Explanation

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 hypertension is a condition of high blood pressure. A client who has hypovolemic shock is more likely to have hypotension, which is a condition of low blood pressure, due to ﬂuid loss and reduced cardiac output.

Choice B Reason: This is incorrect because bradypnea is a condition of slow breathing. A client who has hypovolemic shock is more likely to have tachypnea, which is a condition of fast breathing, due to hypoxia and increased respiratory demand.

Choice C Reason: This is correct because oliguria is a condition of low urine output. A client who has hypovolemic shock may have oliguria due to decreased renal perfusion and activation of the renin-angiotensin-aldosterone system, which causes sodium and water retention.

Choice D reason: This is incorrect because ﬂushing of the skin is a condition of redness and warmth of the skin. A client who has hypovolemic shock may have pallor and coolness of the skin due to vasoconstriction and reduced blood ﬂow.

A. Pneumothorax B. Atelectasis C. Flail chest D. Hemothorax

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because a pneumothorax is a condition in which air enters the pleural space and causes the lung to collapse. It does not cause the chest wall to move inward and outward paradoxically.

Choice B Reason: This is incorrect because atelectasis is a condition in which alveoli collapse and cause reduced gas exchange. It does not cause the chest wall to move inward and outward paradoxically.

Choice C Reason: This is correct because ﬂail chest is a condition in which multiple ribs are fractured and cause a segment of the chest wall to detach from the rest of the thoracic cage. It causes the chest wall to move inward and outward paradoxically, as well as dyspnea and pain.

Choice D Reason: This is incorrect because a hemothorax is a condition in which blood enters the pleural space and causes the lung to collapse. It does not cause the chest wall to move inward and outward paradoxically.
