A nurse is assessing a client who has diabetes mellitus type 2 and presents for a follow-up visit. Which of the following lab values is most indicative of inadequate control of their diabetes since their last primary care visit and requires further teaching?

A.

HbA1c level of 7.5% (nl. 4.4-6.4%)

B.

2-hour post-prandial blood glucose level of 122 mg/dL (nl. <120 mg/dL)

C.

Random blood glucose level of 300 mg/dL (nl. <200 mg/dL)

D.

Fasting blood glucose level of 48 mg/dL (nl. 60-110 mg/dL)

Answer and Explanation

The Correct Answer is C

A. An HbA1c level of 7.5% indicates suboptimal long-term glucose control. The target for many diabetic patients is usually below 7%, but it may not require immediate action compared to more acute indicators.
B. A 2-hour post-prandial blood glucose level of 122 mg/dL is slightly above the normal range but not significantly high. This result alone is not as indicative of inadequate control as other values.
C. A random blood glucose level of 300 mg/dL is significantly elevated and indicates poor glucose control. This value is much higher than the normal range and suggests a need for further teaching and adjustment of diabetes management.
D. A fasting blood glucose level of 48 mg/dL is low and could indicate hypoglycemia rather than inadequate control. This level requires immediate attention but does not reflect poor long-term diabetes management.

Correct Answer is ["11.074"]

Explanation

To calculate the infusion rate, we'll use the following formula:

Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of heparin (units/mL)

First, calculate the desired dose in units/hr:

  • 14 units/kg/hr x 79.1 kg = 1107.4 units/hr

Next, calculate the concentration of heparin in the IV bag:

  • 25,000 units / 250 mL = 100 units/mL

Finally, plug the values into the formula:

  • Infusion rate = 1107.4 units/hr / 100 units/mL = 11.074 mL/hr

Correct Answer is A

Explanation

A. Surgical intervention is the most common and effective treatment for age-related cataracts. Cataract surgery involves the removal of the cloudy lens and replacement with an artificial intraocular lens, which can significantly improve vision.
B. Corticosteroid eye drops are not used to treat cataracts; they are generally prescribed for reducing inflammation in various eye conditions but do not address the lens opacity caused by cataracts.
C. Antioxidant supplements, beta-carotene, and selenium have been studied for their potential role in slowing the progression of cataracts, but they are not considered a primary treatment once cataracts have developed to the point of affecting vision.
D. Eyeglasses or magnifying lenses may help improve vision temporarily in the early stages of cataracts, but they do not treat the underlying cause and are not effective in advanced cases. Surgery remains the definitive treatment.
