Extract:
Question 1 of 5
The nurse prioritizes impaired gas exchange as a problem for a client with an asthma exacerbation. Which of the following is the client's priority goal?
Correct Answer: B
Rationale: Pulse oximetry above 94% (
B) ensures adequate oxygenation. Coughing (
A), wheezing (
C), and peak flow (
D) are secondary.
Question 2 of 5
A client in the beginning stages of an asthma attack has arterial blood gases that reveal the following results: pH 7.51, PaCO2 28 mmHg, PaO2 75 mmHg, O2 saturation 92%, HCO3 24 mEq/L. The nurse interprets this blood gas result as:
Correct Answer: C
Rationale: Elevated pH and low PaCO2 (
C) indicate respiratory alkalosis from hyperventilation. Metabolic alkalosis (
A), metabolic acidosis (
B), and respiratory acidosis (
D) don't match.
Question 3 of 5
The prescription states: "Give drug D 0.5 mg/kg of body weight PO three times a day." The client's weight is 90 kg. Drug D is available from the pharmacy as 25 mg per 5 mL. How many mL will the client receive per 1 dose? (Use preceding zeros if necessary. Do not use trailing zeros. Round to the nearest tenth if necessary.)
Correct Answer: 9.0 mL
Rationale: 0.5 mg/kg × 90 kg = 45 mg; 45 ÷ (25 mg/5 mL) = 9.0 mL (
A).
Question 4 of 5
The nurse is performing a physical assessment on the respiratory system. Although the client is currently confined to bed, they have the strength and ability to move and reposition themselves. The nurse instructs the client to assume which position for the assessment?
Correct Answer: A
Rationale: Sitting upright (
A) optimizes lung expansion for assessment. Semi-Fowler's (
B), supine (
C), and side-lying (
D) limit accuracy.
Question 5 of 5
A client with left lower lobe pneumonia has activity intolerance related to impaired oxygen supply and demand as evidenced by fatigue, dyspnea, and difficulty performing self-care. Which expected outcome must be included in the care plan related to this problem? The client will:
Correct Answer: C
Rationale: Performing self-care without dyspnea (
C) addresses activity intolerance. Oximetry (
A), respiratory rate (
B), and clear breath sounds (
D) are less specific.
