A nurse is reviewing the medical record of a client who has pneumonia. Which of the following serum laboratory values should the nurse expect?

WBC count 15,000/mm3

Sodium 130 mg/dL

BUN 8 mg/dL

Hematocrit 35%

Answer and Explanation

The Correct Answer is A

A high white blood cell (WBC) count is a common sign of infection and inflammation, such as pneumonia. The normal range of WBC count is 4,500 to 11,000/mm3 . Sodium, blood urea nitrogen (BUN), and hematocrit are not directly related to pneumonia and may vary depending on other factors such as hydration status, renal function, and blood loss.

Correct Answer is A

Explanation

Confusion can be a sign of delirium, which is a common complication of immobility in older adults due to sensory deprivation, sleep disturbance, medication side effects, or dehydration. The nurse should assess for other causes of confusion, such as infection or hypoxia, and implement interventions to prevent or treat delirium.

A. Intense pain with movement B. Bounding distal pulses C. Erythema of the toes D. Capillary refill less than 2 seconds

Correct Answer is A

Explanation

Compartment syndrome is a condition in which increased pressure within a confined space compromises blood flow and tissue perfusion, leading to ischemia and necrosis. It can occur after trauma, fracture, or casting of an extremity. The early signs of compartment syndrome include intense pain with movement that is not relieved by analgesics or elevation, paresthesia, pallor, and decreased sensation and motor function of the affected limb. The late signs include absent distal pulses, cyanosis, coldness, and paralysis. Therefore, option A is correct.
