Nursing Questions on Oxygenation Questions
Question 1 of 5
The nurse is caring for a client with a newly inserted chest tube. Which observation would require immediate intervention?
Correct Answer: B
Rationale: The correct answer is B because a chest tube dressing saturated with blood indicates active bleeding, which can lead to complications like hemorrhage or tension pneumothorax. Immediate intervention is needed to prevent further issues. A: Serosanguinous drainage is expected initially after chest tube insertion. C: Intermittent bubbling in the water seal chamber is normal and indicates proper functioning. D: Chest tube secured with tape and sutures is appropriate for stabilization.
Question 2 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 3 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 4 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 5 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
