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 ["100"]

Explanation

To estimate the percentage of body surface area burned using the Rule of Nines, follow these guidelines:

Head and Neck: 9%
Each Arm: 9% (right arm) + 9% (left arm) = 18%
Front of Torso: 18%
Back of Torso: 18%
Each Leg: 18% (right leg) + 18% (left leg) = 36%
Genital Area: 1%

Now, add up the percentages of the burned areas:

9% (head and neck) + 18% (each arm) + 18% (front of torso) + 18% (back of torso) + 36% (each leg) + 1% (genital area) = 100%

So, the nurse should estimate that the client has burned 100% of their body surface area.

A. Respiratory alkalosis B. Metabolic acidosis C. Metabolic alkalosis D. Respiratory acidosis

Correct Answer is D

Explanation

Choice A Reason: This is incorrect because respiratory alkalosis is characterized by a high pH and a low PaCO2, indicating that the client is hyperventilating and losing too much carbon dioxide.

Choice B Reason: This is incorrect because metabolic acidosis is characterized by a low pH and a low bicarbonate level, indicating that the client has an excess of metabolic acids or a loss of base.

Choice C Reason: This is incorrect because metabolic alkalosis is characterized by a high pH and a high bicarbonate level, indicating that the client has an excess of base or a loss of metabolic acids.

Choice D Reason: This is correct because respiratory acidosis is characterized by a low pH and a high PaCO2, indicating that the client is hypoventilating and retaining too much carbon dioxide.
