The nurse auscultates a client's breath sounds as seen in the picture. Which type of normal sounds should the nurse hear over these lung fields?

Crackles.

Vesicular.

Bronchial.

Wheezes.

Answer and Explanation

The Correct Answer is B

A.Crackles: Crackles, also known as rales, are abnormal lung sounds that can indicate conditions such as pneumonia, pulmonary edema, or interstitial lung disease. They are often described as fine or coarse, and they may be heard during inspiration, expiration, or both. Crackles are typically heard over areas of fluid-filled alveoli or small airways.

B. Vesicular. These sounds are typically heard over most of the lung fields and are associated with normal airflow through smaller airways.

C. Bronchial: Bronchial breath sounds are typically heard over the trachea and mainstem bronchi. These sounds are louder and higher in pitch compared to vesicular sounds, with a shorter inspiratory phase and a longer expiratory phase. Hearing bronchial sounds over peripheral lung fields would suggest consolidation or compression of lung tissue, such as in pneumonia or atelectasis.

D. Wheezes: Wheezes are high-pitched, musical sounds heard primarily during expiration. They are typically associated with narrowed airways, such as in asthma, chronic obstructive pulmonary disease (COPD), or bronchitis. Wheezes may be heard over the lung fields if there is widespread airway obstruction or bronchoconstriction.

Correct Answer is D

Explanation

A. Advise the PN that waist circumference measurements are valuable to assess fluid retention but not obesity. Waist circumference is actually a valuable measure for assessing abdominal obesity, which is an important factor in health, independent of BMI. It helps screen for health risks related to overweight and obesity, such as heart disease and type 2 diabetes. Therefore, this option is incorrect.

B. Instruct the PN to measure the client’s waist circumference every 8 hours to assess for changes. Measuring waist circumference does not require frequent assessments like every 8 hours. It’s a simple and inexpensive measurement that provides valuable information about abdominal fat distribution. However, such frequent measurements are unnecessary and impractical for assessing obesity-related risks.

C. Tell the PN that this assessment technique should be performed by the nurse. Waist circumference measurements can be performed by practical nurses (PNs) and other healthcare providers. It’s a straightforward technique that doesn’t require specialized training. Therefore, this option is incorrect.

D. Review the measurement obtained by the PN and compare with ideal measurements for this client. This is the most appropriate action. The nurse should review the PNs measurement of the client’s waist circumference and compare it to established guidelines. Generally, a waist circumference greater than 35 inches for women or greater than 40 inches for men indicates increased risk of obesity-related health problems.

A. Blood urea nitrogen (BUN). B. Glucose. C. White blood cell count (WBC). D. Hematocrit.

Correct Answer is D

Explanation

A. Blood urea nitrogen (BUN): Elevated BUN can indicate kidney problems, but it's not the primary test for melena (black, tarry stools) which suggests upper gastrointestinal bleeding.

B. Glucose: Glucose levels might be abnormal in some conditions that can cause bleeding, but it's not the most specific test for melena.

C. White blood cell count (WBC): WBC might be elevated in response to infection or inflammation, but it's not the most specific test for melena.

D. Hematocrit: Hematocrit measures the percentage of red blood cells in the blood. Melena can indicate significant blood loss, and monitoring hematocrit helps assess the severity of bleeding and potential need for blood transfusions.
