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 B
Explanation
The correct answer is B. "You will need to urinate before the procedure." The rationale for this information is that intermittent catheterization is a method of draining urine from the bladder using a thin, flexible tube called a catheter. It is used to measure residual urine, which is the amount of urine left in the bladder after voiding. Residual urine can indicate problems with bladder function, such as obstruction, infection, or nerve damage .
To measure residual urine, the client should first empty their bladder by urinating normally. Then, the nurse will insert the catheter into the urethra and advance it into the bladder.The nurse will measure the amount of urine that drains out of the catheter and record it as residual urine. The nurse will then remove the catheter and dispose of it .
Correct Answer is D
Explanation
Choice A reason:
Infiltration is not correct: Infiltration occurs when the infused fluid or medication leaks into the surrounding tissue instead of flowing into the vein. This can lead to swelling, coolness, and pallor around the insertion site.
Choice B reason:
Extravasation is not correct: Extravasation is similar to infiltration but specifically refers to the infiltration of vesicant medications, which can cause tissue damage and necrosis.
Choice C reason:
Circulatory overload is not correct: Circulatory overload occurs when a large volume of fluid is infused too quickly, overloading the circulatory system and potentially leading to fluid overload, pulmonary edema, and other related symptoms.
Choice D reason:
Phlebitis is the appropriate fingings. The nurse should document the finding of redness and warmth around the peripheral catheter insertion site as phlebitis. Phlebitis is the inflammation of a vein, often caused by mechanical irritation, chemical irritation, or infection. In this case, the redness and warmth at the insertion site are indicative of inflammation, which is a common sign of phlebitis.
