Question 1 of 5.

The nurse is preparing to obtain capillary blood glucose (CBG) for a client with diabetes mellitus. The nurse should take which action? Select all that apply.

A. Apply gloves for this procedure

B. Have the client wash their hands with soap and water prior to blood collection

C. Collect the second blood drop on the test strip

D. Prick the central part of the finger for the sample

E. Clean and disinfect the glucometer in between uses

Explanation: Gloves protect against blood exposure, hand washing ensures a clean sample, the second drop avoids contamination, and disinfecting the glucometer prevents infection. Pricking the central finger part is less preferred than the side.

Question 2 of 5.

The nurse recognizes which of the following would contraindicate the use of electronic blood pressure monitoring?

A. Coarse tremors

B. Intrajugular central vascular access device

C. Wearing a wrist watch

Explanation: Coarse tremors can interfere with accurate electronic blood pressure readings. Intrajugular devices, wrist watches, and pacemakers do not typically contraindicate use.

A. Exercises both extremities simultaneously.

B. Knows their heart rate should be monitored while exercising.

C. Practices forced resistance against stable objects.

D. Swings their limbs through the full range of motion.
