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. The four main concepts common to nursing that appear in each of the current conceptual models are:

• A. Person, nursing, environment, medicine
• B. Person, health, nursing, support systems
• C. Person, health, psychology, nursing
• D. Person, environment, health, nursing

Correct answer: D

Rationale: The four main concepts common to nursing that appear in each of the current conceptual models are person, environment, health, and nursing. These concepts form the foundational principles that guide nursing practice and theory.

3. A nurse is providing teaching about gastrostomy tube feedings to the parents of a school-age child. Which of the following instructions should the nurse give?

• A. Administer the feeding over 30 minutes
• B. Place the child in a supine position after the feeding
• C. Change the feeding bag and tubing every 3 days
• D. Warm the formula in a warm water bath before administration

Correct answer: B

Rationale: Administering the feeding over 30 minutes helps prevent complications such as aspiration. Placing the child in an upright position after the feeding is recommended to reduce the risk of aspiration. It is essential to change the feeding bag and tubing every 3 days to maintain asepsis and prevent infections. Warming the formula in a warm water bath is the correct method as using a microwave can create hot spots that may burn the child's mouth or throat.

4. Which technique in physical examination is used to assess the movement of air through the tracheobronchial tree?

• A. Palpation
• B. Auscultation
• C. Inspection
• D. Percussion

Correct answer: B

Rationale: The correct answer is B: Auscultation. Auscultation is a technique in physical examination used to assess the movement of air through the tracheobronchial tree. During auscultation, healthcare providers listen to lung sounds using a stethoscope to detect abnormalities such as wheezing, crackles, or diminished breath sounds, which can indicate conditions affecting the airways or lungs. Palpation (Choice A) involves feeling the body for abnormalities, Inspection (Choice C) involves visual examination, and Percussion (Choice D) involves tapping on the body to produce sounds that can help in assessing underlying structures, but they are not directly used to assess air movement through the tracheobronchial tree.

5. A healthcare professional is assessing a client who has a pulmonary embolism. Which of the following information should the healthcare professional not expect to find?

• A. Bradypnea
• B. Pleural friction rub
• C. Petechiae
• D. Tachycardia

Correct answer: A

Rationale: In a client with a pulmonary embolism, bradypnea, which is abnormally slow breathing, is not an expected finding. Pulmonary embolism typically presents with tachypnea (rapid breathing) due to the body's compensatory mechanism to increase oxygen levels. Pleural friction rub, petechiae, and tachycardia are commonly associated with a pulmonary embolism due to the impaired oxygenation and increased workload on the heart. Therefore, the healthcare professional should not expect to find bradypnea during the assessment of a client with a pulmonary embolism.
