Which return demonstration by a client indicates that teaching about performing a blood glucose monitoring test has been effective?
 
  1. The client punctures the fingertip.
  2. The client puts on gloves.
  3. The client smears the blood on the reagent strip.
  4. The client washes the hands.

Question 2

The nurse is reviewing laboratory results for a client. Which diagnostic study determines how well blood glucose levels have been controlled in the client?
 
  1. Blood chemistry
  2. Capillary blood glucose
  3. Hemoglobin A1c
  4. Serum electrolytes

Answer to Question 1

Correct Answer: 4
Rationale 1: Once the appropriate site is selected for puncture, the side of the finger is used where there are fewer nerve endings.
Rationale 2: Because the client is performing self-blood glucose monitoring, applying gloves is not necessary.
Rationale 3: Once the specimen is obtained, one holds the reagent strip under the puncture site until enough blood covers the indicator square. It is not smeared on the pad, which would cause an inaccurate reading.
Rationale 4: One of the first steps the client would perform is hand washing for infection control.

Answer to Question 2

Correct Answer: 3
Rationale 1: A blood chemistry is a number of tests performed on blood serum. It can include LDH, CK, and AST.
Rationale 2: The capillary blood glucose is used to determine or monitor blood glucose levels of clients at one point in time but not over time.
Rationale 3: The glycosylated hemoglobin or hemoglobin A1c (HbA1c) is a measurement of blood glucose that is bound to hemoglobin. Hemoglobin A1c is a reflection of how well blood glucose levels have been controlled.
Rationale 4: Serum electrolytes are often routinely ordered for any client admitted to a hospital as a screening test for electrolyte and acidbase imbalances. The most commonly ordered serum tests are for sodium, potassium, chloride, and bicarbonate ions.
