A patient with a history of adrenal insufficiency has been admitted to the intensive care unit due to an acute adrenal crisis.

The patient is experiencing nausea and joint pain.

The patient’s vital signs are as follows: temperature of 102 F (38.9° C), heart rate of 138 beats/minute, and blood pressure of 80/60 mm Hg. What is the first intervention the nurse should implement?

Choice A rationale
A chest x-ray is a critical diagnostic tool for a patient presenting with flu-like symptoms, fever, chest congestion, and increased breathing difficulties. It can help identify conditions such as pneumonia or other lung diseases, which could be causing the patient’s symptoms.
Choice B rationale
While hydration is important, running a 0.9% sodium chloride IV infusion at 150 mL/hour is not the most immediate need for this patient. The patient’s symptoms are primarily respiratory, and there is no indication of dehydration.
Choice C rationale
A sputum culture could be useful for diagnosing bacterial infections of the respiratory tract. However, it is not the most immediate need for this patient, as the results of a culture test can take time to come back.
Choice D rationale
This is the correct answer. Given the patient’s increased breathing difficulties, starting oxygen therapy can help improve the patient’s oxygen levels and ease their breathing.
Choice E rationale

Starting a peripheral IV might be necessary for administering medications or fluids, but it is not the most immediate need in this scenario.
Choice F rationale
While controlling the patient’s fever is important, it is not as immediate a need as performing a chest x-ray and starting oxygen therapy.

Choice A rationale
While a high-calorie, high-protein diet can be beneficial for patients recovering from surgery or illness, it is not the immediate next step after collecting bone aspirate specimens for culture and sensitivity and applying a cast to a patient’s lower leg. The priority is to address the infection identified through the bone aspirate specimens.

Choice B rationale
Beginning parenteral antibiotic therapy is the appropriate next step after collecting bone aspirate specimens for culture and sensitivity in a patient with osteomyelitis. Osteomyelitis is an infection in the bone, and antibiotics are typically the first line of treatment. Therefore, this choice is the correct answer.
Choice C rationale
Administering antiemetic agents would be appropriate if the patient were experiencing nausea or vomiting. However, there is no indication in the question that the patient is experiencing these symptoms. Therefore, this choice is not the correct answer.
Choice D rationale
Bivalving the cast for distal compromise would be appropriate if there were signs of compromised circulation or nerve function below the level of the cast. However, there is no indication in the question that the patient is experiencing these issues. Therefore, this choice is not the correct answer.
