A nurse is assessing a client who has hypoxemia for a late sign. Which finding should the nurse expect?

Hypertension

Tachycardia

Pallor

Bradypnea

Answer and Explanation

The Correct Answer is C

A: Hypertension is not typically a late sign of hypoxemia. It can occur in various conditions but is not specific to hypoxemia.

B: Tachycardia is an early sign of hypoxemia as the body attempts to compensate for low oxygen levels by increasing the heart rate.

C: Pallor is a late sign of hypoxemia. It indicates poor oxygenation and perfusion, often seen when the body can no longer compensate for the lack of oxygen.

D: Bradypnea, or slow breathing, is not a typical sign of hypoxemia. Hypoxemia usually causes an increase in respiratory rate (tachypnea) as the body tries to take in more oxygen.

Correct Answer is C

Explanation

A: A trochanter roll is used to prevent external rotation of the hips, not to prevent plantar flexion contractures.

B: A sheepskin heel pad provides cushioning and helps prevent pressure ulcers on the heels but does not prevent plantar flexion contractures.

C: A footboard is used to prevent plantar flexion contractures by keeping the feet in a neutral position. This helps maintain proper alignment and prevents the muscles and tendons from shortening.

D: An abduction pillow is used to maintain hip abduction, typically after hip surgery, and does not prevent plantar flexion contractures.

Correct Answer is ["4.0"]

Explanation

Step 1: Determine the dosage required. 320 mg

Step 2: Determine the concentration of the suspension. 400 mg per 5 mL

Step 3: Calculate the volume needed. 320 mg ÷ 400 mg per 5 mL = 320 ÷ 400 × 5 = 0.8 × 5 = 4 mL

The nurse should administer 4.0 mL per dose.
