A nurse is preparing to check the capillary blood glucose level of a school-age child. Which of the following actions should the nurse plan to take?
Allow the skin antiseptic to dry prior to puncturing the child's finger.
Place a cool washcloth on the child's finger for 5 min prior to the procedure.
Test the first drop of blood obtained after puncturing the child's finger.
Puncture the center of the pad of the child's index finger.
The Correct Answer is A
Choice A rationale:
The correct answer is choice A. This action is crucial to ensure accurate capillary blood glucose testing. Allowing the skin antiseptic to dry before puncturing the child's finger helps prevent contamination of the blood sample, which can lead to inaccurate results. Wet antiseptic can dilute the blood sample and affect the glucose reading.
Choice B rationale:
This choice is incorrect because placing a cool washcloth on the child's finger is not standard practice before capillary blood glucose testing. While warmth can help increase blood flow and make the puncture process more comfortable, using a cool washcloth is not recommended, as it may constrict blood vessels and make it harder to obtain a sufficient blood sample.
Choice C rationale:
This choice is incorrect because testing the first drop of blood obtained after puncturing the child's finger is not recommended. The first drop of blood can be diluted with interstitial fluid and may not provide an accurate glucose reading. It's important to wipe away the first drop and use the subsequent drop of blood for testing.
Choice D rationale:
This choice is incorrect because puncturing the center of the pad of the child's index finger is not the recommended site for capillary blood glucose testing. The sides of the fingertip contain an adequate blood supply and are less painful for the child. Puncturing the center of the fingertip can be more painful and may not yield a sufficient blood sample.

Correct Answer is B
Explanation
Choice A rationale:
Urine osmolality 500 mOsm/kg. Urine osmolality is a measure of urine concentration and is not a reliable indicator of infection. It reflects the kidney's ability to concentrate urine and can vary based on hydration status and other factors. An elevated urine osmolality could suggest dehydration, not necessarily infection.
Choice B rationale:
WBC 17,500/mm3. This is the correct choice. An elevated white blood cell count (WBC) is a hallmark sign of infection. The body's immune response to an infection often includes an increase in WBC count, particularly the neutrophil count. This elevation is known as leukocytosis and is a red flag for infection.
Choice C rationale:
BUN 12 mg/dL. Blood Urea Nitrogen (BUN) measures kidney function and hydration status. While an elevated BUN can indicate dehydration, it is not a specific marker for infection. BUN levels can be influenced by various factors, including diet and renal function.
Choice D rationale:
Urine specific gravity 1.014. Urine-specific gravity reflects the concentration of solutes in urine and the kidney's ability to concentrate or dilute urine. While changes in urine specific gravity can indicate dehydration or overhydration, it is not a direct indicator of infection. An infection is better detected through changes in WBC count and other clinical signs.
Correct Answer is D
Explanation
Choice A rationale:
Gently lift the traction weights off the floor when repositioning the client. Rationale: This choice is not recommended in the care of a client in skeletal traction. Traction weights should never be lifted off the floor as they provide the necessary counter traction to align and immobilize the fractured bone. Lifting the weights could disrupt the traction and jeopardize the healing process.
Choice B rationale:
Reduce intake of foods containing fiber while nonambulatory. Rationale: While constipation can be a concern for clients in skeletal traction due to decreased mobility, reducing fiber intake is not the appropriate intervention. Adequate fiber intake is important to promote regular bowel movements and prevent constipation. Hydration and mobility exercises are more suitable approaches to manage constipation.
Choice C rationale:
Perform passive range-of-motion exercises to the affected extremity every 2 hours. Rationale: Passive range-of-motion exercises are important to maintain joint mobility and prevent muscle atrophy in a nonambulatory client. However, performing these exercises every 2 hours might be excessive and could cause unnecessary discomfort for the client. Range-of-motion exercises are usually done every 4 to 8 hours to strike a balance between maintaining joint health and providing rest.
Choice D rationale:
Apply protective padding to the end of the pin sites. Rationale: This is the correct choice. Applying protective padding to the end of the pin sites is crucial to prevent pressure ulcers and infection. The pin sites are potential entry points for bacteria, and protecting them helps reduce the risk of infection. Padding also prevents pressure on the skin and underlying tissues, reducing the potential for pressure injuries.
