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 choice is incorrect because flatened neck veins are not a sign of cardiac tamponade. Cardiac tamponade is a condition in which fluid accumulates in the pericardial sac that surrounds the heart, causing compression and impaired filling of the heart chambers. This leads to reduced cardiac output and hypotension. One of the manifestations of cardiac tamponade is distended neck veins due to increased venous pressure and impaired venous return.
Choice B Reason: This choice is incorrect because bradycardia is not a sign of cardiac tamponade. Bradycardia is a condition in which the heart rate is slower than normal (less than 60 beats per minute). It may be caused by various factors such as vagal stimulation, medication side effects, hypothyroidism, or sinus node dysfunction. It may cause symptoms such as fatigue, dizziness, or syncope, but it does not indicate cardiac tamponade.
Choice C Reason: This choice is incorrect because sudden lethargy is not a specific sign of cardiac tamponade. Lethargy is a condition in which the person feels tired, sluggish, or drowsy. It may be caused by various factors such as sleep deprivation, depression, infection, anemia, or hypoglycemia. It may affect the person's mental and physical performance, but it does not indicate cardiac tamponade.
Choice D Reason: This choice is correct because muffled heart sounds are a sign of cardiac tamponade. Muffled heart sounds are heart sounds that are fainter or softer than normal due to reduced transmission of sound waves through fluid-filled pericardial sac. They may indicate that the heart function is compromised by cardiac tamponade and require immediate intervention such as pericardiocentesis (removal of fluid from pericardial sac).
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.
