A nurse is preparing to administer a unit of red blood cells. The nurse's responsibility is to compare and verify the information on the blood label with the client's information. Which of the following should the nurse use as the priority source of verification?

Choice A reason: Headache can be associated with FES; however, it is not typically considered an early sign. It may occur as a part of the broader spectrum of symptoms.

Choice B reason: Dyspnea, or difficulty breathing, is one of the earliest signs of FES. Patients may experience shortness of breath due to fat globules obstructing pulmonary vessels.

Choice C reason: Red-brown petechiae, which are small, pinpoint hemorrhages, can appear on the skin and are a classic sign of FES, often found in the axillary region or on the chest.

Choice D reason: Altered mental status, including confusion and drowsiness, can occur early in FES due to fat emboli traveling to the cerebral circulation.

The correct answer is: c. Prepare the client for intubation.

Choice A: Prepare to administer a vasopressor

Reason: Vasopressors are typically used to manage hypotension (low blood pressure) and are not a standard treatment for myasthenic crisis. Myasthenic crisis primarily involves respiratory muscle weakness, which can lead to respiratory failure, rather than issues with blood pressure.

Choice B: Administer an anticholinesterase medication

Reason: While anticholinesterase medications like pyridostigmine are used to manage myasthenia gravis, they are generally not recommended during a myasthenic crisis. During a crisis, the focus is on stabilizing the patient, often requiring more immediate interventions such as intubation and mechanical ventilation.

Choice C: Prepare the client for intubation

Reason: Intubation is a critical intervention in a myasthenic crisis due to the risk of respiratory failure. The crisis is characterized by severe muscle weakness, including the muscles that control breathing. Intubation ensures that the airway is protected and that the patient can receive adequate ventilation.

Choice D: Instruct the client to perform pursed lip breathing

Reason: Pursed lip breathing is a technique used to improve breathing efficiency in conditions like chronic obstructive pulmonary disease (COPD). However, it is not appropriate for managing a myasthenic crisis, where the primary issue is severe muscle weakness leading to respiratory failure.
