While auscultating 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 'Inspiratory crackles at the bases.' Crackles are low-pitched, bubbling sounds typically heard during inspiration, which aligns with the nurse's finding. Expiratory wheezes are high-pitched sounds and are not consistent with the described auscultation findings. The lower third of both lungs refers to the bases, not the apices, so option C is incorrect. Pleural friction rubs are grating sounds heard during both inspiration and expiration, unlike the described finding of only hearing the sounds during inhalation in the lower third of both lungs.

Correct Answer: B

Rationale: The correct intervention is to keep the patient NPO until the gag reflex returns after a bronchoscopy. This is important because a local anesthetic is used during the procedure to suppress the gag and cough reflexes. Monitoring the return of these reflexes helps prevent the risk of aspiration and ensures the patient can safely resume oral intake. While blood-tinged mucus can occur after bronchoscopy, it is a common occurrence and not a cause for immediate concern. Placing the patient on bed rest for an extended period is unnecessary, and elevating the head of the bed to a high-Fowler's position is not specifically required post-bronchoscopy.

Correct Answer: C

Rationale: In the early phase of heart failure, fine crackles are likely to be heard upon auscultation of the lungs. Fine crackles are characterized as discontinuous, high-pitched sounds of short duration heard on inspiration. Rhonchi are continuous rumbling, snoring, or rattling sounds mainly on expiration, which are often associated with airway secretions. Coarse crackles are a series of long-duration, discontinuous, low-pitched sounds during inspiration, typically indicating fluid in the alveoli. Wheezes are continuous high-pitched musical sounds on inspiration and expiration, commonly heard in conditions like asthma or chronic obstructive pulmonary disease (COPD). Therefore, the correct choice is C, as it describes the expected lung sounds in a patient with early heart failure.

Correct Answer: C

Rationale: The drop in SpO2 to 88% indicates that the patient is hypoxemic and needs supplemental oxygen when exercising. Administering PRN supplemental oxygen is the priority action to correct the hypoxemia and ensure adequate oxygenation during activity. Notifying the healthcare provider can be done after stabilizing the patient's oxygen levels. Documenting the response to exercise is important but secondary to addressing the immediate hypoxemia. Encouraging the patient to pace activity is not sufficient to address the acute drop in SpO2 and provide the necessary oxygen support.

Correct Answer: C

Rationale: The correct answer is 'I should inhale deeply and blow out as hard as I can during the test.' This statement indicates effective teaching because for PFT, the patient needs to inhale deeply and exhale forcefully. This maneuver helps in assessing lung function accurately. Choices A, B, and D are incorrect. Using an inhaler right before the test may alter the test results, which is not recommended. Fasting for 8 hours is not necessary for a PFT, and checking blood pressure and pulse every 15 minutes after the test is not part of the PFT procedure.
