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 A
Explanation
Choice A rationale:
This response indicates an understanding of the teaching about celiac disease. Rice is a gluten-free grain, which makes rice pudding a suitable dessert option for a child with celiac disease. Gluten is a protein found in wheat, barley, and rye, and individuals with celiac disease need to avoid gluten-containing foods.
Choice B rationale:
Barley is a gluten-containing grain, and feeding a child a barley-based breakfast cereal is not appropriate for someone with celiac disease. Gluten-containing grains can trigger adverse reactions in individuals with celiac disease due to their inability to properly digest gluten.
Choice C rationale:
Rye bread contains gluten, and making sandwiches using rye bread is not a suitable choice for a child with celiac disease. Gluten-free bread options, typically made from rice, corn, or other gluten-free flour, should be chosen instead.
Choice D rationale:
Chocolate malt may contain ingredients that could potentially contain gluten, and it's not a safe snack option for a child with celiac disease. Individuals with celiac disease need to be cautious about hidden sources of gluten in processed foods.
Correct Answer is A
Explanation
Choice A rationale:
Obtain the specimen by swabbing the infant's rectum using a sterile culture swab. This is the correct choice. When collecting a stool specimen from an infant, the rectal swab method is commonly used. A sterile culture swab helps prevent contamination and ensures accurate results for detecting the presence of ova and parasites in the stool.
Choice B rationale:
Place a urine collection device on the infant until the specimen is obtained. This choice is not appropriate for collecting a stool specimen. A urine collection device is used for collecting urine, not stool. The specimen for ova and parasites needs to be taken directly from the rectum or diaper to accurately identify any infestations.
Choice C rationale:
Transfer the specimen to the collection container using povidone-iodine-soaked gauze. While povidone-iodine is an antiseptic, it is not typically used to transfer stool specimens. Using a sterile swab or a clean, dry container is more suitable for collecting and transporting stool samples to the lab.
Choice D rationale:
Maintain the specimen at room temperature after collection until it is transferred to the lab. Stool specimens for ova and parasites usually require refrigeration to prevent the degradation and growth of potential pathogens. Room temperature might lead to the overgrowth of bacteria and parasites, affecting the accuracy of test results.
