A nurse is reinforcing teaching about HbA1c with a client who has type 1 diabetes mellitus.
Which of the following information should the nurse include?
An HbA1c value greater than 8% indicates diabetic control of blood sugar.
The HbA1c value is altered by eating habits the day before the test.
The HbA1c value determines long-term blood glucose control for the past 120 days.
An HbA1c test is performed once per year.
The Correct Answer is C
The HbA1c value determines long-term blood glucose control for the past 120 days. This is because the HbA1c test measures what percentage of hemoglobin proteins in your blood are coated with sugar (glycated). Hemoglobin proteins in red blood cells live for around 120 days, so the test reflects your average blood sugar level for the past two to three months.
Choice A is wrong because an HbA1c value greater than 8% indicates poor diabetic control of blood sugar. The HbA1c target for most people with type 1 diabetes is 48 mmol/mol (or 6.5%) or lower.
Choice B is wrong because the HbA1c value is not altered by eating habits the day before the test. The test does not require fasting and can be done at any time of the day.
Choice D is wrong because an HbA1c test should be performed more than once per year.
The frequency of the test depends on the type of diabetes, your treatment plan and your blood sugar level. For example, you may need the test twice a year if you have good blood sugar control, or four times a year if you take insulin or have trouble keeping your blood sugar level within your target range.

Correct Answer is A
Explanation
Encourage the client to help care for their surgical incision. This can help the client accept the body image change and promote healing.
Choice B is wrong because suggesting that the client decide about reconstruction as soon as possible can pressure the client and interfere with their coping process.
Choice C is wrong because postponing referrals to support services until the client requests them can delay the client’s emotional recovery and increase their isolation.
Choice D is wrong because avoiding talking to the client about the surgery can indicate that the nurse is uncomfortable with the topic and discourage the client from expressing their feelings.
Correct Answer is D
Explanation
This action indicates that the charge nurse should intervene because adding food coloring to the tube feeding is not recommended and can cause adverse effects such as aspiration, diarrhea, and allergic reactions.
Choice A is wrong because checking the volume of the aspirate is a correct action to assess gastric residual volume and prevent complications such as nausea, vomiting, and aspiration.
Choice B is wrong because checking the pH of the aspirate is a correct action to verify the placement of the NG tube and prevent accidental administration of enteral feeding into the lungs.
Choice C is wrong because administering 15 mL of water before administering the feeding is a correct action to flush the NG tube and prevent clogging.
Normal ranges for gastric residual volume are less than 250 mL for adults and less than 5 mL/kg for children. Normal ranges for pH of gastric aspirate are less than 5.5 for adults and less than 4 for children.
