A nurse is caring for a client who is scheduled for a blood sampling for a serum creatinine level. The client asks the nurse, "What is the purpose of this test?" Which of the followingresponses should the nurse give?

"This test will inform your provider if you are anemic."

"This test will inform your provider if you have an infection."

"This test will inform your provider if you have a thyroid disorder."

"This test will inform your provider how your kidneys are functioning."

Answer and Explanation

The Correct Answer is D

a. "This test will inform your provider if you are anemic." Serum creatinine is not used to assess anemia. Anemia is often evaluated through tests like hemoglobin and hematocrit.

b. "This test will inform your provider if you have an infection." Serum creatinine is not a direct indicator of infection. It is primarily used to assess kidney function.

c. "This test will inform your provider if you have a thyroid disorder." Serum creatinine is not

used to evaluate thyroid function. Thyroid function is typically assessed through thyroid function tests.

d. "This test will inform your provider how your kidneys are functioning." This is the correct

response. Serum creatinine is a waste product that is filtered by the kidneys, and elevated levels may indicate impaired renal function.

Correct Answer is B

Explanation

a. Neck vein distention: Neck vein distention may indicate fluid overload, but it is not a direct measure of fluid losses.

b. Body weight: Monitoring body weight before and after hemodialysis provides a direct

measure of fluid losses. Hemodialysis removes excess fluid, and changes in body weight reflect fluid balance.

c. Abdominal girth: Abdominal girth may be affected by fluid accumulation but is not a direct measure of fluid losses during hemodialysis.

d. Blood pressure: While blood pressure may be influenced by fluid status, it is not a specific measure of fluid losses during hemodialysis. Body weight is a more direct indicator of fluid removal.

A. Pleural friction rub B. Fine rales C. Rhonchi D. Expiratory wheeze

Correct Answer is D

Explanation

a. Pleural friction rub: Pleural friction rub is a grating sound heard during inspiration and

expiration and is associated with inflammation of the pleura. It is not typically associated with asthma exacerbation.

b. Fine rales: Fine rales (crackles) are usually heard during inspiration and can be associated with conditions such as pneumonia or pulmonary fibrosis. They are not the typical lung sounds in

asthma exacerbation.

c. Rhonchi: Rhonchi are low-pitched wheezes heard during inspiration and expiration. While they can be associated with asthma, expiratory wheezes are more specific to asthma

exacerbation.

d. Expiratory wheeze: Expiratory wheezes are high-pitched, musical sounds heard during

expiration and are characteristic of asthma exacerbation. They result from narrowed airways and increased airway resistance.
