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 Reason: This is correct because dopamine is a vasopressor that increases the contractility and stroke volume of the heart, which results in an increased systolic blood pressure.
Choice B Reason: This is incorrect because dopamine can cause tachycardia as a side effect, but this does not indicate a therapeutic effect. An increased radial heart rate can also indicate other conditions, such as anxiety, fever, or dehydration.
Choice C Reason: This is incorrect because dopamine does not reduce cardiac output, but rather increases it by improving the pumping function of the heart.
Choice D Reason: This is incorrect because dopamine does not reduce urine output, but rather increases it by stimulating the renal blood vessels and enhancing renal perfusion.
Correct Answer is ["A","C","E"]
Explanation
Choice A Reason: This choice is correct because verifying the prescribed ventilator settings daily is an important intervention to ensure that the client is receiving adequate ventilation and oxygenation. The ventilator settings include parameters such as tidal volume, respiratory rate, fraction of inspired oxygen (FiO2), positive end-expiratory pressure (PEEP), and peak inspiratory pressure (PIP). The nurse should check that the settings match the prescription and report any changes or alarms to the provider.
Choice B Reason: This choice is incorrect because applying restraints if the client becomes agitated is not a recommended intervention to prevent complications. Restraints may cause injury, infection, or psychological distress to the client and increase the risk of ventilator-associated pneumonia (VAP). The nurse should use alternative methods to manage agitation, such as sedation, analgesia, or environmental modification.
Choice C Reason: This choice is correct because administering pantoprazole as prescribed is an important intervention to prevent complications. Pantoprazole is a proton pump inhibitor (PPI) that reduces the production of stomach acid and prevents gastroesophageal reflux disease (GERD) and stress ulcers. These conditions can cause aspiration, bleeding, or infection in clients who are receiving mechanical ventilation.
Choice D Reason: This choice is incorrect because repositioning the endotracheal tube to the opposite side of the mouth daily is not a recommended intervention to prevent complications. Repositioning the endotracheal tube may cause trauma, bleeding, or displacement of the tube, which can compromise the airway and ventilation of the client. The nurse should secure the tube with tape or a device and check its position regularly using chest x-ray or end-tidal CO2 monitoring.
Choice E Reason: This choice is correct because elevating the head of the bed to at least 30° is an important intervention to prevent complications. Elevatin the head of the bed helps to reduce the risk of aspiration, which is the inhalation of gastric contents or secretions into the lungs. Aspiration can cause pneumonia, atelectasis, or respiratory failure in clients who are receiving mechanical ventilation.
