A nurse is providing teaching to a client who recently had a hemoglobin A1c level obtained. Which of the following statements should the nurse include in the teaching?
"This lab measures your average blood glucose over a 3-month period."
"An increase in your hemoglobin A1c level indicates glycemic control."
"This lab value is a good indicator of short-term nutritional status."
"You will need to fast before getting this test."
The Correct Answer is A
A. "This lab measures your average blood glucose over a 3-month period." The hemoglobin A1c test reflects the average blood glucose levels over the past 2 to 3 months by measuring the percentage of glucose attached to hemoglobin in red blood cells. Since red blood cells have a lifespan of about 120 days, this test provides a long-term view of glycemic control.
B. "An increase in your hemoglobin A1c level indicates glycemic control." An increase in hemoglobin A1c levels actually indicates poor glycemic control, not improvement. Higher values mean blood glucose has been elevated over time, which can lead to complications such as neuropathy, nephropathy, and retinopathy in diabetic patients.
C. "This lab value is a good indicator of short-term nutritional status." The hemoglobin A1c test is not used to assess short-term nutritional status. Instead, it measures long-term blood glucose trends. For evaluating short-term changes in nutrition, blood glucose logs or postprandial glucose readings are better tools to use.
D. "You will need to fast before getting this test." Fasting is not required for the hemoglobin A1c test. The result is not affected by recent food intake, making it convenient for patients. This feature makes it more practical than fasting plasma glucose or oral glucose tolerance tests when assessing overall glycemic control in diabetes management.

Correct Answer is D
Explanation
A. Use a washcloth to clean the denture surfaces: Dentures should be cleaned using a soft-bristled toothbrush or denture brush to effectively remove food particles and plaque. A washcloth is not effective for thoroughly cleaning denture surfaces.
B. Floss dentures as part of daily cleaning: Flossing is intended for natural teeth, not dentures. Dentures require brushing and soaking, but do not have spaces between teeth that need flossing.
C. Wipe dentures before storing them in a dry container at night: Dentures should be stored in water or a denture solution overnight to prevent them from drying out and warping. Keeping them in a dry container is incorrect.
D. Wrap gloved fingers with gauze to remove dentures: Wrapping gloved fingers with gauze provides a better grip and reduces the risk of injury or dropping the dentures during removal. This is the appropriate technique when assisting with denture care.
Correct Answer is C
Explanation
A. Offer the client thickened liquids to drink: Offering thickened liquids can help reduce the risk of aspiration in clients with dysphagia, which is common after a stroke. However, this should be done after confirming that the client has a safe swallowing mechanism, such as an intact gag reflex. Administering liquids before assessing swallowing safety can increase the risk of aspiration pneumonia.
B. Monitor the client for indications of fatigue during meals: Fatigue can compromise the client’s ability to chew and swallow effectively, increasing the risk of aspiration. Monitoring for this is important but is not the immediate priority when the client is already drooling, a sign that they may be unable to manage their oral secretions. Ensuring safe swallowing should be addressed before monitoring meal-time fatigue.
C. Check the client's gag reflex: Checking the gag reflex is the most important initial action because it directly assesses the client’s ability to swallow safely. Drooling after a stroke often indicates impaired neuromuscular control, which puts the client at high risk for aspiration. The gag reflex gives immediate information on whether oral intake is safe.
D. Monitor the client's ability to speak consistently: Monitoring speech consistency can provide insights into neurological recovery and motor control, but it is not the first concern in a drooling stroke patient. The primary danger is aspiration due to impaired swallowing. Speaking ability does not directly reflect swallowing safety.
