Nursing Questions on Oxygenation Questions
Question 1 of 5
A client with bronchitis is prescribed guaifenesin. What is the primary purpose of this medication?
Correct Answer: B
Rationale: Step 1: Guaifenesin is an expectorant that works by thinning mucus in the airways. Step 2: Thinning mucus helps to make it easier for the client to cough up and clear the mucus. Step 3: This promotes expectoration, which helps to relieve congestion and improve breathing. Step 4: Therefore, the primary purpose of guaifenesin is to thin mucus and promote expectoration in clients with bronchitis.
Question 2 of 5
A client with pulmonary embolism is receiving anticoagulation therapy. Which lab value requires immediate intervention?
Correct Answer: A
Rationale: Rationale: INR measures the effectiveness of anticoagulation therapy. INR of 1.2 is below the therapeutic range for pulmonary embolism treatment, indicating inadequate anticoagulation and risk of clot progression. Immediate intervention is necessary to adjust medication dosage. Platelet count, aPTT, and hemoglobin levels are within normal range and do not require immediate intervention.
Question 3 of 5
On auscultation of a patient's lungs, the nurse hears low-pitched, bubbling sounds during inhalation in the lower third of both lungs. How should the nurse document this finding?
Correct Answer: A
Rationale: The correct answer is A: Inspiratory crackles at the bases. This finding indicates the presence of crackles, which are discontinuous, non-musical sounds heard during inspiration. Crackles in the lower third of both lungs suggest the presence of fluid or mucus in the alveoli or small airways. The term "bases" refers to the lower portions of the lungs. Crackles are typically associated with conditions such as pneumonia, heart failure, or pulmonary edema. Explanation of other choices: B: Expiratory wheezes in both lungs - Wheezes are continuous, high-pitched musical sounds heard during expiration and are typically associated with asthma or bronchitis. This does not match the description provided in the question. C: Abnormal lung sounds in the apices of both lungs - The apices refer to the upper portions of the lungs. The description in the question does not match this location. D: Pleural friction rub in the right and left lower
Question 4 of 5
Which action should the nurse plan to prevent aspiration in a high-risk patient?
Correct Answer: B
Rationale: Rationale: Option B is correct as placing a patient with altered consciousness in a side-lying position helps prevent aspiration by allowing gravity to aid in drainage of secretions and prevents the tongue from obstructing the airway. Turning and repositioning an immobile patient (Option A) helps prevent pressure ulcers but does not directly prevent aspiration. Inserting a nasogastric tube for feeding (Option C) is not a preventive measure for aspiration and may actually increase the risk. Monitoring respiratory symptoms in an immunosuppressed patient (Option D) is important for identifying respiratory infections but does not directly prevent aspiration.
Question 5 of 5
A patient with pneumonia has an oxygen saturation of 88% on room air. Which intervention is most important?
Correct Answer: B
Rationale: The correct answer is B: Initiate oxygen therapy at 2 liters per minute via nasal cannula. Oxygen saturation of 88% indicates hypoxemia, requiring immediate intervention to improve oxygenation. Administering oxygen via nasal cannula at 2 liters per minute can help increase oxygen levels and alleviate symptoms. Choice A (Administer prescribed bronchodilators) is incorrect as bronchodilators are not the first-line treatment for hypoxemia in pneumonia. Choice C (Encourage the use of an incentive spirometer every hour) is incorrect as while important for respiratory hygiene, it does not address the immediate need for oxygen therapy in a hypoxemic patient. Choice D (Increase the patient's fluid intake to thin secretions) is incorrect as it addresses secretion management, which is not the priority in this scenario where oxygenation is compromised.
