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 A
Explanation
Choice A: Evaluating chest expansion is the first action that the nurse should take, because it assesses the client's respiratory status and potential for pneumothorax, which is a life-threatening condition that can result from chest trauma. The nurse should compare the movement of both sides of the chest and listen for breath sounds.
Choice B: Checking pupillary response to light is an important action, but not the first one, because it assesses the client's neurological status and potential for brain injury. The nurse should observe the size, shape, and symmetry of the pupils and their reaction to light.
Choice C: Checking the client's response to questions about place and time is another important action, but not the first one, because it assesses the client's level of consciousness and orientation. The nurse should ask the client simple questions such as their name, date, and location.
Choice D: Assessing the capillary refill is a less important action, and not the first one, because it assesses the client's peripheral circulation and tissue perfusion. The nurse should press on the client's nail beds or fingertips and observe how quickly the color returns.
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.
