A nurse is using a glucometer to measure a client's capillary blood glucose level.
Which of the following actions should the nurse take?
Keep the finger in a dependent position.
Wear sterile gloves.
Select the central tip of a finger
Test the first drop of blood that forms after the puncture.
The Correct Answer is A
A. Keep the finger in a dependent position:
- Keeping the finger in a dependent position (lower than the heart) helps promote blood flow to the fingertips, making it easier to obtain a blood sample. This position can facilitate the formation of a blood drop, improving the chances of obtaining an adequate sample for testing.
B. Wear sterile gloves:
- Sterile gloves are not typically necessary for routine capillary blood glucose monitoring. Clean, non-sterile gloves are generally sufficient for this procedure. However, the nurse should perform proper hand hygiene to minimize the risk of contamination.
C. Select the central tip of a finger:
- The central tip of the finger is more sensitive, and choosing this area may cause greater discomfort for the client. The sides of the fingertips are often preferred for capillary blood glucose testing as they have a good blood supply and are less sensitive.
D. Test the first drop of blood that forms after the puncture:
- The initial drop may contain tissue fluid or contaminants from the puncture site, so it is important to use the first drop to obtain a representative blood sample. This step contributes to the accuracy of the blood glucose measurement.

Correct Answer is C
Explanation
The correct answer is C. Place a pillow under the child's head.
Rationale: The nurse should protect the child from injury by helping them to the floor and clearing away furniture or other items. The nurse should also place a pillow under the child's head to prevent head trauma and turn them onto their side to prevent aspiration of saliva or vomit. The nurse should not put anything in the child's mouth, as this could cause choking or damage to the teeth or tongue. The nurse should also not turn the child onto their back, as this could compromise their airway. The nurse should not restrain the child's upper extremities, as this could increase muscle spasms and cause injury.
Correct Answer is D
Explanation
Answer: D. Abnormal Involuntary Movement Scale
Rationale: The Abnormal Involuntary Movement Scale is a diagnostic tool that assesses the severity of tardive dyskinesia, a disorder that results in involuntary repetitive body movements caused by long-term use of antipsychotic drugs.
