"I will return any unused vials of insulin to the pharmacy once they have been on the unit for 1 month."

"I can keep the current vial of insulin in use stored at room temperature."

"I will store unopened vials of insulin in the freezer."

Answer and Explanation

The Correct Answer is C

A. "I will discard the current vial of insulin after six doses have been withdrawn.": Insulin vials can be used for up to 28 days when stored at room temperature, not discarded based on the number of doses withdrawn.

B. "I will return any unused vials of insulin to the pharmacy once they have been on the unit for 1 month.": Unused insulin vials should be stored properly (refrigerated for unopened vials) and do not need to be returned unless there is an error or expired stock.

C. "I can keep the current vial of insulin in use stored at room temperature.": Once opened, insulin vials can be stored at room temperature (below 86°F or 30°C) for up to 28 days to prevent degradation.

D. "I will store unopened vials of insulin in the freezer.": Freezing insulin damages its effectiveness; unopened insulin should be refrigerated but never frozen.

Correct Answer is A

Explanation

A. Fasting blood glucose 155 mg/dL (70-105): A fasting blood glucose of 155 mg/dL exceeds the threshold for diabetes risk (≥126 mg/dL). This result strongly indicates impaired glucose regulation or diabetes mellitus.

B. Casual blood glucose 178 mg/dL (less than 200): Casual glucose <200 mg/dL does not meet the diagnostic criteria for diabetes or prediabetes, as casual glucose ≥200 mg/dL is diagnostic of diabetes in symptomatic individuals.

C. HbA1c 5.2% (49%-69%): HbA1c levels ≥5.7% indicate prediabetes, and ≥6.5% is diagnostic of diabetes. This value is within the normal range.

D. 2-hr blood glucose 132 mg/dL (less than 200): A 2-hour glucose level after an oral glucose tolerance test (OGTT) of 140-199 mg/dL indicates prediabetes, and ≥200 mg/dL confirms diabetes. This value does not indicate risk.

A. Buffalo hump also known as fat pads on upper back B. Obese extremities C. Purple or Dark Striations on skin D. Tremors E. Truncal obesity F. Round moon-shaped face

Correct Answer is ["A","C","E","F"]

Explanation

A. Buffalo hump (fat pads on the upper back): Fat redistribution is a classic sign of Cushing's syndrome.

B. Obese extremities: Cushing's syndrome typically presents with truncal obesity, not obesity of the extremities.

C. Purple or dark striations on the skin: These are caused by skin thinning and stretching due to increased cortisol levels.

D. Tremors: Tremors are not commonly associated with Cushing's syndrome.

E. Truncal obesity: Central obesity is a hallmark of Cushing's syndrome.

F. Round moon-shaped face: This is another characteristic sign of fat redistribution in Cushing's syndrome.
