1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A student learns about modifiable risk factors for coronary artery disease. Which factors does this include? (Select one that does not apply)

• A. Age
• B. Hypertension
• C. Obesity
• D. Smoking

Correct answer: A

Rationale: Hypertension, obesity, smoking, and excessive stress are all modifiable risk factors for coronary artery disease, as they can be changed or controlled through interventions. Age, on the other hand, is a nonmodifiable risk factor, meaning it cannot be altered. Understanding the difference between modifiable and nonmodifiable risk factors is essential in preventive healthcare strategies.

3. A healthcare provider collaborates with a respiratory therapist to complete pulmonary function tests (PFTs) for a client. Which statements should the healthcare provider include in communications with the respiratory therapist prior to the tests? (Select ONE that does not apply)

• A. I ensured the client did not use bronchodilator medication within the specified timeframe.
• B. The client is prepared to undergo the examination in radiology.
• C. Physical therapy has approved the client for treadmill exercise.
• D. I instructed the client not to smoke for the required duration before the test.

Correct answer: C

Rationale: For accurate pulmonary function tests (PFTs), it is essential to communicate that the client did not use bronchodilators within the specified timeframe, did not smoke for the required duration before the test, and can comply with different breathing maneuvers. The use of a treadmill is not part of the PFT procedure and is unrelated to the testing process. Therefore, communicating about the client's ability to run on a treadmill is not relevant to the pulmonary function tests being conducted by the respiratory therapist.

4. A healthcare professional wishes to provide client-centered care in all interactions. Which action by the healthcare professional best demonstrates this concept?

• A. Assesses for cultural influences affecting healthcare
• B. Ensures that all the client's basic needs are met
• C. Informs the client and family about all upcoming tests
• D. Thoroughly orients the client and family to the room

Correct answer: A

Rationale: Client-centered care focuses on individualizing care to meet the client's unique needs, preferences, and values. Assessing for cultural influences affecting healthcare allows the healthcare professional to provide culturally sensitive and competent care, respecting the client's beliefs and practices. It promotes effective communication, understanding, and collaboration, essential components of client-centered care.

5. A client with emphysema is being assessed by a nurse. Which clinical manifestation should the nurse expect?

• A. Decreased chest expansion
• B. Cyanosis
• C. Pursed-lip breathing
• D. Bradypnea

Correct answer: C

Rationale: Pursed-lip breathing is a common manifestation in clients with emphysema. It helps to increase the duration of exhalation and reduce air trapping, aiding in the management of the condition. Decreased chest expansion and bradypnea are not typically associated with emphysema. While cyanosis can occur in severe cases, pursed-lip breathing is a more specific and commonly observed sign of emphysema.
