Correct Answer is ["167 "]

Explanation

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.

Pulmonary Embolism (PE): Symptoms, Signs & Treatment

Correct Answer is D

Explanation

Choice A Reason: This choice is incorrect because warm, flushed skin is not a sign of respiratory acidosis. Warm, flushed skin may indicate fever, infection, inflammation, or allergic reaction, but it does not reflect the acid-base imbalance in the blood.

Choice B Reason: This choice is incorrect because hyperactive deep tendon reflexes are not a sign of respiratory acidosis. Hyperactive deep tendon reflexes may indicate hypocalcemia, hyperthyroidism, or spinal cord injury, but they do not reflect the carbon dioxide level in the blood.

Choice C Reason: This choice is incorrect because bounding peripheral pulses are not a sign of respiratory acidosis. Bounding peripheral pulses may indicate increased cardiac output, anxiety, or hyperthyroidism, but they do not reflect the pH level in the blood.

Choice D Reason: This choice is correct because widened QRS complexes are a sign of respiratory acidosis. QRS complexes are the segments on an electrocardiogram (ECG) that represent the depolarization of the ventricles. A normal QRS complex duration is 0.06 to 0.10 seconds, and a widened QRS complex duration is more than 0.12 seconds. A widened QRS complex may indicate hyperkalemia, which is a common complication of kidney failure and respiratory acidosis. Hyperkalemia is a condition in which the serum potassium level is higher than normal (more than 5 mEq/L). It may cause cardiac arrhythmias, muscle weakness, or paralysis.
