A nurse is preparing an insulin infusion for a client with diabetic ketoacidosis (DKA). The client weighs 125 lbs. and has a prescription to administer continuous insulin intravenously at 0.3 units/kg/hr. How many units of insulin per hour should the nurse program on the IV pump? (Round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["17.05"]

Convert weight from pounds to kilograms:
125 lbs ÷ 2.2 = 56.82 kg

Calculate insulin dose:
0.3 units/kg/hr × 56.82 kg = 17.05 units/hr

Rounded to the nearest whole number: 17 units/hr.

Correct Answer is D

Explanation

A. Initiating fluid resuscitation is a vital component of burn management during the resuscitation phase, but it follows airway stabilization in priority.
B. Inserting an indwelling urinary catheter is important for monitoring fluid output and kidney function, but it is not the immediate priority.
C. Pain management is essential in burn care, but it is not the most urgent intervention during the initial phase of care.
D. According to the ABCs of emergency care (Airway, Breathing, Circulation), securing the airway is always the first priority, especially in clients with burns to the chest and upper body where airway edema and inhalation injury are likely.

A. Metabolic acidosis B. Respiratory alkalosis C. Respiratory acidosis D. Metabolic alkalosis

Correct Answer is A

Explanation

A. The pH is low (normal 7.35–7.45), indicating acidemia. The HCO₃⁻ is decreased (normal 22–26 mEq/L), indicating a metabolic cause. The PaCO₂ is normal (35–45 mm Hg), showing no respiratory compensation or cause. These findings are consistent with metabolic acidosis.

B. Respiratory alkalosis would show an elevated pH (>7.45) and decreased PaCO₂ (<35 mm Hg).

C. Respiratory acidosis would show a low pH (<7.35) and elevated PaCO₂ (>45 mm Hg).

D. Metabolic alkalosis would show a high pH (>7.45) and elevated HCO₃⁻ (>26 mEq/L).
