1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

3. For abdominal inspection, in which of the following positions should a patient be placed?

• A. Prone
• B. Trendelenburg
• C. Supine
• D. Side-lying

Correct answer: C

Rationale: The supine position is ideal for abdominal inspection as it allows the healthcare provider to easily access and examine the abdomen. In the supine position, the patient lies flat on their back with arms at their sides, providing a clear view and access to the abdominal area for inspection.

4. 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.

5. A healthcare professional is reviewing the health records of five clients. Which of the following clients is not at risk for developing acute respiratory distress syndrome?

• A. A client who experienced a near-drowning incident
• B. A client following coronary artery bypass graft surgery
• C. A client who has a hemoglobin of 15.1 g/dL
• D. A client who has dysphagia

Correct answer: C

Rationale: Acute respiratory distress syndrome (ARDS) is a severe lung condition that can be triggered by various factors such as near-drowning incidents, surgeries like coronary artery bypass graft, and underlying conditions like dysphagia. Hemoglobin levels do not directly influence the risk of developing ARDS. A hemoglobin level of 15.1 g/dL falls within the normal range and does not predispose an individual to ARDS.
