CDCES Clinical Procedures and Protocols 2

Question 1

Which site is preferred for continuous glucose monitor (CGM) sensor insertion in adults?

Accepted Answer

Abdomen or upper arm

Answer

The abdomen and upper arm are FDA-approved and preferred CGM insertion sites for most adult devices due to consistent interstitial glucose readings.

Question 2

Before performing a finger-stick blood glucose check, which step is most important for accurate results?

Accepted Answer

Clean the site with alcohol and let it fully dry

Answer

Alcohol residue on the finger can dilute the blood sample and cause falsely low readings; the site must fully dry before lancing.

Question 3

A patient reports that their insulin pump infusion set site has become red, swollen, and tender. What is the priority action?

Accepted Answer

Remove the infusion set and rotate to a new site

Answer

Signs of infusion site infection or occlusion require immediate removal of the set and rotation to a new site to restore insulin delivery and prevent worsening infection.

Question 4

When teaching self-injection technique for insulin, which angle is recommended for a person with very little subcutaneous tissue using a 4 mm pen needle?

Accepted Answer

90 degrees without a skin fold

Answer

A 4 mm pen needle is short enough that a 90-degree angle without a skin fold is appropriate even in lean individuals, minimizing intramuscular injection risk.

Question 5

Which protocol best describes the sick-day rules for patients with type 1 diabetes on insulin?

Accepted Answer

Check blood glucose and ketones more frequently; never skip insulin doses

Answer

During illness, counter-regulatory hormones raise blood glucose; patients should increase monitoring frequency, maintain insulin doses, and check for ketones.
