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 clamping the client's chest tube can cause a tension pneumothorax, which is a life-threatening condition that requires immediate intervention.
Choice B Reason: This is incorrect because increasing the client's wall suction can cause excessive negative pressure in the pleural space, which can damage the lung tissue and impair ventilation.
Choice C Reason: This is correct because repositioning the client can help relieve chest burning, which may be caused by irritation of the intercostal nerves by the chest tube or by air trapping in the pleural space.
Choice D Reason: This is incorrect because stripping the client's chest tube can create high negative pressure in the pleural space, which can damage the lung tissue and impair ventilation.
Correct Answer is D
Explanation
Choice A Reason: This choice is incorrect because providing a brightly lit environment may stimulate the client and increase the intracranial pressure. A brightly lit environment is an environment that has a high level of illumination or brightness. It may be used for clients who have depression, seasonal affective disorder, or insomnia, but it does not help to reduce the intracranial pressure.
Choice B Reason: This choice is incorrect because teaching controlled coughing and deep breathing may increase the intrathoracic pressure and increase the intracranial pressure. Controlled coughing and deep breathing are techniques that help to clear the airway and improve lung expansion. They may be used for clients who have respiratory infections, chronic obstructive pulmonary disease, or postoperative complications, but they do not help to reduce the intracranial pressure.
Choice C Reason: This choice is incorrect because encouraging a minimum intake of 2000 mL (67.5 oz) of clear fluids per day may cause fluid overload and increase the intracranial pressure. Fluid overload is a condition in which the body has too much fluid, which can impair the function of the heart, lungs, and kidneys. Therefore, restricting fluid intake and using diuretics may be indicated for clients who have increased intracranial pressure.
Choice D Reason: This choice is correct because elevating the head of the bed 20° may help to improve the venous drainage and decrease the intracranial pressure. As explained above, positioning the client in a semi-Fowler's or high-Fowler's position can facilitate breathing and prevent further complications. However, elevating the head of the bed more than 30° may decrease the cerebral perfusion pressure (CPP), which is the difference between the mean arterial pressure (MAP) and the intracranial pressure (ICP). A normal CPP range is 70 to 100 mm Hg, and a low CPP (<50 mm Hg) can cause cerebral ischemia, herniation, or death. Therefore, elevating the head of the bed to a moderate angle (20°) may be optimal for clients who have increased ICP.
