The patient’s data indicate that the patient is in shock, which is a life-threatening condition characterized by inadequate tissue perfusion and organ dysfunction. The patient has a low blood pressure, a high heart rate, a fever, and a metabolic acidosis, which suggest that the patient may have septic shock, which is caused by a severe infection that triggers a systemic inflammatory response. The nurse should anticipate an order to administer phenylephrine (Neo-Synephrine), which is a vasopressor agent that constricts the blood vessels and increases the blood pressure and tissue perfusion. Phenylephrine is recommended as a first-line agent for septic shock by the Surviving Sepsis Campaign guidelines1. 8.4% sodium bicarbonate is not indicated for the treatment of septic shock, as it may worsen the acid-base balance and increase the risk of complications2. 0.9% sodium chloride is a normal saline solution that may be used for fluid resuscitation, but it may not be sufficient to restore the blood pressure and may cause fluid overload, hyperchloremia, and kidney injury3. Amiodarone (Cordarone) is an antiarrhythmic drug that is used to treat ventricular tachycardia or fibrillation, but it is not effective for septic shock and may cause hypotension, bradycardia, and other adverse effects4.

The patient's clinical presentation and recent history of femoral shaft and rib fractures are highly suggestive of a fat embolism syndrome (FES). FES typically occurs after long bone fractures and is characterized by sudden onset of respiratory distress, neurological symptoms, and petechial rash, which aligns with the new-onset headache, central and peripheral cyanosis, and petechiae of the neck and anterior chest wall observed in this patient. The fat emboli originate from the bone marrow and enter the bloodstream, traveling to the lungs and other organs, leading to respiratory and systemic symptoms. References: =

The patient’s vital signs indicate hypertensive urgency or emergency (BP 190/100, HR 126), with a differential radial pulse, suggesting aortic dissection. Nitroprusside is a potent vasodilator used in the management of hypertensive crises and can help reduce blood pressure and the shear force on the aortic wall, which is crucial in managing aortic dissection. Nitroglycerin, diltiazem, and digoxin are not appropriate first-line therapies for this condition. References: AACN Adult CCRN Certification Review Course, AACN CCRN Exam Handbook.

A patient with acetaminophen overdose is at risk for acute liver failure, which can lead to coagulopathy. This condition is often marked by an increased International Normalized Ratio (INR) due to impaired synthesis of clotting factors in the liver. Decreasing level of consciousness can also result from hepatic encephalopathy, a complication of liver failure. References: = CCRN Exam Handbook and AACN's Certification Review Course materials.
