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. Decreased calcium level: NG tube drainage is more likely to result in hypokalemia (decreased potassium) than hypocalcemia (decreased calcium).

b. Decreased potassium level: NG tube drainage, which contains stomach contents, can lead to loss of potassium. Monitoring for hypokalemia is crucial as it can result in cardiac dysrhythmias.

c. Elevated magnesium level: NG tube drainage is not typically associated with an increase in magnesium levels.

d. Elevated sodium level: NG tube drainage may contribute to sodium loss, leading to hyponatremia, rather than hypernatremia.

A. Instruct the client to place his chin to his chest and swallow. B. Withdraw the tube if the client gags during insertion. C. Place the client in a supine position. D. Measure the tube for insertion from the tip of the nose to the umbilicus.

Correct Answer is A

Explanation

a. Instruct the client to place his chin to his chest and swallow: This technique helps facilitate the passage of the nasogastric tube through the pharynx and into the esophagus.

b. Withdraw the tube if the client gags during insertion: Gagging is a normal response, and

withdrawing the tube may lead to repeated attempts and discomfort for the client. Encouraging the client to swallow can help overcome the gag reflex.

c. Place the client in a supine position: The client is usually positioned in a semi-Fowler's position or upright to ease tube insertion and minimize the risk of aspiration.

d. Measure the tube for insertion from the tip of the nose to the umbilicus: The proper

measurement for nasogastric tube insertion is typically from the tip of the nose to the earlobe and then down to the xiphoid process, not the umbilicus.
