Question 1 of 5
What is the underlying rationale for why a nurse assesses a client with emphysema for clinical indicators of hypoxia?
Correct Answer: C
Rationale: Lack of adequate surface area for aeration is correct. Emphysema causes alveolar destruction, reducing gas exchange surface area, leading to chronic hypoxia. Mucus production, infections, and bronchiole inflammation are more relevant to chronic bronchitis or other conditions.
Question 2 of 5
A nurse is providing teaching to a client who has angina pectoris and a new prescription for nitroglycerin sublingual tablets. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: D
Rationale: Calling 911 if pain persists after taking 3 nitroglycerin tablets 5 minutes apart is correct. Persistent pain suggests a possible myocardial infarction, requiring immediate medical intervention. The other options deviate from the standard protocol for nitroglycerin use.
Question 3 of 5
A nurse is teaching a client who has chronic obstructive pulmonary disease (COPD) about how to use an albuterol inhaler. Which of the following actions by the client indicates an understanding of the teaching?
Correct Answer: A
Rationale: Holding the breath for 10 seconds after inhaling allows medication absorption. Waiting 10 minutes, quick inhalation, or exhaling during inhalation are incorrect techniques.
Question 4 of 5
The nurse is providing education to a client on ways to prevent the development of a pulmonary embolism. Which of the following statements would require further teaching?
Correct Answer: A
Rationale: Crossing the legs increases the risk of venous stasis and clot formation, requiring further teaching. Quitting smoking, staying hydrated, and exercising are appropriate preventive measures.
Question 5 of 5
A nurse is assessing a client with the diagnosis of left-sided heart failure. Which clinical finding should the nurse expect the client to experience?
Correct Answer: A
Rationale: Orthopnea is correct. Left-sided heart failure causes pulmonary congestion, leading to difficulty breathing when lying flat. Bradycardia, diaphoresis, and yellow sputum are not hallmark symptoms of left-sided heart failure.
