The nurse's auscultation of a client's lung fields reveals the presence of a wheeze. The nurse should recognize that this adventitious sound results from what pathophysiologic process?

Air being diverted from the trachea to the bronchi

Air passing through constricted passageways

Air increasing in turbulence in a wide passage

Air leaking from the alveoli into the pleural space

Answer and Explanation

The Correct Answer is B

A. Air being diverted from the trachea to the bronchi does not explain the cause of a wheeze. This is a normal part of airflow distribution.
B. Air passing through constricted passageways is correct. A wheeze is a high-pitched, musical sound that occurs when air flows through narrowed or obstructed airways, as seen in conditions like asthma, chronic obstructive pulmonary disease (COPD), or bronchitis.
C. Air increasing in turbulence in a wide passage is incorrect. Wheezing occurs due to airway narrowing, not widening.
D. Air leaking from the alveoli into the pleural space describes pneumothorax, which presents with absent breath sounds rather than wheezing.

Correct Answer is D

Explanation

A. Observing for increased abdominal girth is important for conditions such as ascites but is not the priority assessment for a suspected abdominal aneurysm.
B. Palpating the abdomen for masses or pulsations is contraindicated in suspected abdominal aneurysms, as it may cause rupture.
C. Auscultating for a friction rub is used for liver or spleen inflammation and is not relevant in this case.
D. Listening with the bell of the stethoscope for vascular sounds is correct because an abdominal aneurysm may produce a bruit, which can be heard over the affected artery. This assessment helps confirm the presence of turbulent blood flow, a key sign of an aneurysm.

A. Lithotomy B. Dorsal recumbent C. Sim's position D. Prone

Correct Answer is B

Explanation

A. Lithotomy position is used for gynecologic, rectal, or urologic exams and would not be comfortable for a client with low back pain.
B. Dorsal recumbent position is correct because it allows the client to lie on their back with knees bent, reducing strain on the lower back while facilitating assessment of the chest, extremities, and peripheral pulses.
C. Sim’s position is used for rectal examinations or enemas and is not ideal for assessing the chest and extremities.
D. Prone position (lying face down) would exacerbate low back pain and make it difficult to examine the chest and extremities.
