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 D
Explanation
Choice A Reason: This is incorrect because crepitus in the area above and surrounding the insertion site is not a serious finding that requires notification of the provider. Crepitus is a crackling sensation that occurs when air leaks into the subcutaneous tissue. It is usually harmless and resolves on its own.
Choice B reason: This is incorrect because bubbling of the water in the water seal chamber with exhalation is a normal finding that indicates that air is being removed from the pleural space. Bubbling should stop when the pneumothorax is resolved.
Choice C Reason: This is incorrect because eyelets are not visible is not a serious finding that requires notification of the provider. Eyelets are small holes at the end of the chest tube that allow air and fluid to drain from the pleural space. They are usually covered by a dressing and may not be visible.
Choice D Reason: This is correct because movement of the trachea toward the unaffected side is a serious finding that indicates a tension pneumothorax, which is a life-threatening condition that occurs when air accumulates in the pleural space and causes pressure on the mediastinum. The nurse should notify the provider immediately and prepare for needle decompression or chest tube insertion.
Correct Answer is A
Explanation
Choice A Reason: This is correct because respiratory acidosis is characterized by a low pH and a high PaCO2, indicating that the client has impaired ventilation and excess carbon dioxide in the blood.
Choice B Reason: This is incorrect because respiratory alkalosis is characterized by a high pH and a low PaCO2, indicating that the client has increased ventilation and reduced carbon dioxide in the blood.
Choice C Reason: This is incorrect because metabolic acidosis is characterized by a low pH and a low HCO3, indicating that the client has an excess of metabolic acids or a loss of base in the blood.
Choice D Reason: This is incorrect because metabolic alkalosis is characterized by a high pH and a high HCO3, indicating that the client has an excess of base or a loss of metabolic acids in the blood.
