1. Which of the following white blood cell (WBC) counts clearly indicates leukocytosis?

• A. 4,500/mm³
• B. 7,000/mm³
• C. 10,000/mm³
• D. 25,000/mm³

Correct answer: D

Rationale: Leukocytosis is defined as an increase in the total white blood cell count. A normal WBC count typically ranges from 4,500 to 10,000/mm³. A WBC count of 25,000/mm³, as indicated in choice D, is significantly higher than the normal range and clearly indicates leukocytosis.

2. Which of the following is included in Orem’s theory?

• A. Maintenance of a sufficient intake of air
• B. Self-perception
• C. Love and belonging
• D. Physiological needs

Correct answer: A

Rationale: Orem's theory, also known as the Self-Care Deficit Nursing Theory, focuses on individuals' ability to perform self-care to maintain health and well-being. One specific component of this theory is the maintenance of a sufficient intake of air, which is crucial for sustaining life and overall health. Option A is the correct choice as it directly relates to meeting physiological needs, such as the intake of air, to support optimal functioning and health. Choices B, C, and D are incorrect as they do not specifically align with Orem's emphasis on self-care and meeting physiological requirements.

3. When planning care for a client with severe acute respiratory distress syndrome (SARS), which of the following actions should not be included in the care plan?

• A. Administer antibiotics
• B. Provide supplemental oxygen
• C. Administer antiviral medications
• D. Administer bronchodilators

Correct answer: A

Rationale: Severe acute respiratory distress syndrome (SARS) is caused by a virus, not bacteria, and antibiotics are ineffective against viral infections. Therefore, administering antibiotics would not be appropriate in the care plan for a client with SARS. The priority interventions for SARS include providing supplemental oxygen to improve oxygenation, administering antiviral medications to target the viral infection, and using bronchodilators to help with bronchospasm or airway constriction. Antibiotics are not indicated unless there is a secondary bacterial infection present.

4. In the emergency department, a nurse is assessing a client involved in a motor vehicle crash. Findings include absent breath sounds in the left lower lobe with dyspnea, blood pressure 118/68 mm Hg, heart rate 124/min, respirations 38/min, temperature 38.6 C (101.4 F), and SaO2 92% on room air. What action should the nurse take first?

• A. Obtain a chest X-ray.
• B. Prepare for chest tube insertion.
• C. Administer oxygen via high-flow mask.
• D. Initiate IV access.

Correct answer: C

Rationale: In this scenario, the client is presenting with signs of respiratory distress, including absent breath sounds, dyspnea, and a low SaO2 level. The priority action should be to improve oxygenation by administering oxygen via a high-flow mask. This intervention aims to increase the oxygen supply to the client's lungs, helping to address the hypoxemia. Once oxygenation is optimized, further interventions, such as obtaining a chest X-ray, preparing for chest tube insertion, or initiating IV access, can be considered based on the client's condition and healthcare provider's orders.

5. A healthcare professional is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the professional recognize?

• A. Confusion
• B. Pale skin
• C. Bradycardia
• D. Hypotension

Correct answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.
