A nurse reviews the arterial blood gas (ABG) values of a client admitted with pneumonia: pH, 7.32; PaCO2, 48 mm Hg; PaO2, 70 mm Hg; and HCO3, 24 mEq/L. What do these values indicate?

A. Inform the primary care provider that the patient may have an infection:
Explanation: The presence of an elevated oral temperature and new onset of fine crackles on lung auscultation suggests a potential respiratory infection, which is a significant concern in a patient with sickle cell disease. Notifying the primary care provider allows for further evaluation and appropriate management of the infection.

B. Liaise with the respiratory therapist and consider high-flow oxygen:
Explanation: While oxygenation may be necessary, especially if the patient is experiencing respiratory distress, addressing the potential infection is the priority. Consulting with the respiratory therapist and considering high-flow oxygen can be part of the overall plan based on the primary care provider's recommendations.

C. Apply supplementary oxygen by nasal cannula:
Explanation: Providing oxygen support may be necessary, but it should be done in consultation with the primary care provider, who can guide the appropriate level of oxygen therapy based on the patient's condition.

D. Administer bronchodilators by nebulizer:
Explanation: Bronchodilators are typically used for conditions like asthma or COPD, and their use might not be the primary intervention in the context of a sickle cell crisis with signs of a potential respiratory infection. Addressing the infection takes precedence, and the primary care provider's input is essential in determining the appropriate course of action.

A. Development of a buffalo hump and moon face:
This is associated with Cushing's syndrome, a disorder characterized by prolonged exposure to high levels of cortisol.

B. Central obesity and purple striations:
Also indicative of Cushing's syndrome, where excess cortisol can lead to the accumulation of fat in the abdominal area (central obesity) and the development of purple stretch marks (striae).

C. Sudden weight loss without dieting:
This is more characteristic of hyperthyroidism, where the thyroid gland is overactive, leading to increased metabolism and unintended weight loss.

D. Positive Trousseau's sign when checking the client's blood pressure:
Trousseau's sign is associated with hypocalcemia and is seen in conditions affecting the parathyroid gland rather than the thyroid. It involves carpal spasm induced by inflating a blood pressure cuff above the systolic pressure for a few minutes.
