Nursing Questions on Oxygenation Questions
Question 1 of 5
A client is diagnosed with tuberculosis and started on isoniazid therapy. What is the most important teaching point?
Correct Answer: B
Rationale: The correct answer is B because yellowing of the skin or eyes can indicate liver toxicity, a serious side effect of isoniazid. Reporting this symptom promptly can prevent further complications. Choice A is incorrect because vitamin C does not interfere with isoniazid therapy. Choice C is incorrect as stopping medication prematurely can lead to drug resistance. Choice D is incorrect as antacids can reduce the effectiveness of isoniazid.
Question 2 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 3 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 4 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.
Question 5 of 5
Which assessment finding in a patient receiving oxygen therapy is most concerning?
Correct Answer: C
Rationale: The correct answer is C: Lethargy and confusion. This is the most concerning assessment finding in a patient receiving oxygen therapy because it indicates potential oxygen deprivation to the brain, which can lead to serious complications. Lethargy and confusion are signs of hypoxia, which can be life-threatening if not addressed promptly. Respiratory rate of 24 breaths per minute (choice A) may indicate increased effort to breathe but is not as immediately concerning as hypoxia. Oxygen saturation of 92% (choice B) is below the normal range but not critically low. Mild nasal dryness (choice D) is a common side effect of oxygen therapy and does not indicate a serious issue with oxygen delivery.
