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 D
Explanation
The nurse should determine if the client has prepared their advance directives, which are legal documents that specify the client’s wishes regarding medical care in case they become incapacitated. Advance directives can include a living will, a durable power of attorney for health care, or a do-not-resuscitate order. The nurse should respect the client’s autonomy and right to self-determination by asking about their advance directives and ensuring that they are documented and followed.
Choice A is wrong because the nurse should not delay the admission while the client fills out the facility’s advance directives form.
The client has the right to refuse or accept any treatment, including filling out an advance directives form.
The nurse should inform the client about the benefits of having advance directives, but should not coerce or pressure them to complete one.
Choice B is wrong because the nurse should not confirm with the client’s family that the consent form has been signed.
The consent form is a legal document that indicates that the client has given informed consent for the surgery, which means that they have received adequate information about the procedure, its risks and benefits, and alternative options.
The consent form should be signed by the client, unless they are a minor, mentally incompetent, or unable to communicate.
The nurse should verify that the consent form has been signed by the client or their legal representative before the surgery.
Choice C is wrong because the nurse should not explain to the client that signing the facility’s consent form means they cannot refuse care.
Signing the consent form does not waive the client’s right to withdraw consent at any time before or during the surgery.
The nurse should inform the client that they can change their mind and refuse care at any point, and that their decision will be respected and honored.
Correct Answer is B
Explanation
The indirect Coombs test is used to detect antibodies against foreign red blood cells in the maternal serum. This test can help identify maternal-fetal blood incompatibility, which can cause hemolytic disease of the newborn.
Choice A is wrong because homocysteine is a type of amino acid and is not related to blood compatibility.
Choice C is incorrect because erythropoietin is a hormone that regulates red blood cell production and is not a specific test for detecting maternal-fetal blood incompatibility.
Choice D is not the correct answer as aPTT (activated partial thromboplastin time) is a test used to evaluate blood clotting factors and is not directly related to monitoring maternal-fetal blood incompatibility.
