CDCES Safety and Infection Control 3

Question 1

A patient reports storing insulin pens in the refrigerator but notices the injection site burns severely. What is the MOST likely contributing factor?

Accepted Answer

Cold insulin is being injected directly from the refrigerator

Answer

Injecting cold insulin can cause pain and tissue irritation; insulin should be brought to room temperature before injection.

Question 2

During a home visit, a CDCES observes a patient recapping used insulin pen needles and storing them for reuse. What is the PRIMARY safety concern with this practice?

Accepted Answer

Repeated use increases needle trauma, skin flora introduction, and infection risk

Answer

Reusing pen needles dulls the tip, damages the coating, and can introduce skin bacteria into the subcutaneous tissue, raising infection risk.

Question 3

What is the recommended minimum distance between insulin injection sites during site rotation to prevent lipohypertrophy?

Accepted Answer

2 cm (about 0.8 inches)

Answer

Injections should be spaced at least 1–2 cm apart within a region to avoid repeated trauma and lipohypertrophy formation.

Question 4

A CDCES is counseling a patient about insulin pump infusion set changes. How often should infusion sets typically be changed to minimize infection risk?

Accepted Answer

Every 2–3 days

Answer

Infusion sets should be changed every 2–3 days to prevent site infections, occlusions, and insulin degradation.

Question 5

A patient with diabetic peripheral neuropathy reports stepping on a nail but feeling minimal pain. What is the MOST important immediate action to teach?

Accepted Answer

Seek immediate medical evaluation regardless of pain level

Answer

Any puncture wound in a person with diabetes and neuropathy requires immediate medical evaluation due to the high risk of rapid infection progression.
