Fundamentals of Nursing Oxygenation Questions Questions
Question 1 of 5
Which medication improves oxygenation in bronchospasm?
Correct Answer: B
Rationale: Bronchodilators (e.g., albuterol) relax bronchial smooth muscles, opening airways and improving oxygenation in bronchospasm, unlike antibiotics, diuretics, or antihypertensives.
Question 2 of 5
Which finding suggests a patient is experiencing respiratory acidosis?
Correct Answer: A
Rationale: Respiratory acidosis occurs with a low pH (30) and high PaCO2 (50 mmHg) due to CO2 retention, unlike normal (35-45) or alkalotic values.
Question 3 of 5
Which lifestyle change most improves oxygenation in a patient with obesity?
Correct Answer: C
Rationale: Weight loss reduces chest wall resistance and improves lung expansion in obesity, enhancing oxygenation, unlike increasing calories, reducing activity, or sleeping supine.
Question 4 of 5
A nurse is collecting data from a client who has gastroesophageal reflux disease (GERD) and reports having heartburn every night. Which of the following actions should the nurse identify as a contributing factor to the client’s heartburn?
Correct Answer: B
Rationale: Orange juice is highly acidic and can irritate the esophagus, leading to increased heartburn symptoms. Regular consumption of acidic beverages like orange juice can exacerbate GERD symptoms, making this a likely contributing factor to the client's heartburn.
Question 5 of 5
When administering oxygen therapy, what should the nurse prioritize to ensure the safety of the client?
Correct Answer: B
Rationale: Monitoring the client's oxygen saturation levels using a pulse oximeter is crucial to assess the effectiveness of oxygen therapy and ensure the client's oxygen needs are being met adequately.
