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 administering intravenous pain medication is not the priority action for a client who has sustained partial-thickness burns. Pain medication may be indicated for pain relief and comfort, but it does not address the potential life-threatening complications of burns such as shock, infection, or respiratory distress.
Choice B Reason: This choice is incorrect because drawing blood for a CBC count is not the priority action for a client who has sustained partial-thickness burns. A CBC count may be useful to monitor the hematological status and detect any signs of infection or anemia, but it does not address the immediate needs of the client
Choice C Reason: This choice is incorrect because inserting an indwelling urinary catheter is not the priority action for a client who has sustained partial-thickness burns. A urinary catheter may be necessary to measure the urine output and assess the renal function and fluid balance, but it does not address the most urgent problem of the client.
Choice D Reason: This choice is correct because inspecting the mouth for signs of inhalation injuries is the priority action for a client who has sustained partial-thickness burns. Inhalation injuries are caused by inhaling hot air, smoke, or toxic gases that damage the airway and lungs. They can cause airway obstruction, bronchospasm, pulmonary edema, or respiratory failure. Therefore, the nurse should inspect the mouth for signs such as soot, singed nasal hairs, burns on the lips or tongue, hoarseness, stridor, or wheezes. The nurse should also monitor the oxygen saturation and arterial blood gases to assess the oxygenation and ventilation status of the client.
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.
