A nurse is reinforcing teaching about performing a glucose test with an adolescent client who has diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?
"I will collect the first drop of blood by wiping it on the test strip."
"I will stick the side of my finger with the lancet instead of the center."
“I will hold the lancet at a 45-degree angle when piercing my skin."
“I will place my finger under cool water for a few seconds before the stick."
The Correct Answer is B
A. "I will collect the first drop of blood by wiping it on the test strip." The first drop of blood should be wiped away with a clean cotton ball or gauze. This is because the first drop can contain interstitial fluid that may dilute the sample and lead to an inaccurate reading.
B. "I will stick the side of my finger with the lancet instead of the center." Sticking the side of the fingertip is less painful and allows for better blood flow compared to the center of the fingertip, which is often more sensitive.
C. “I will hold the lancet at a 45-degree angle when piercing my skin.” The lancet should typically be held at a 90-degree angle (straight) when piercing the skin, not at a 45-degree angle. A correct angle ensures proper blood flow and reduces discomfort.
D. “I will place my finger under cool water for a few seconds before the stick.” Using cool water before testing can cause the blood vessels to constrict. Warm water is recommended before testing, as it helps increase blood flow and makes it easier to obtain a sample.

Correct Answer is B
Explanation
A. Administer magnesium sulfate IM to the child: Seizures are typically managed with anticonvulsant medications or other specific treatments, but magnesium sulfate is primarily used in other conditions, such as preeclampsia in pregnant women.
B. Place a folded blanket under the child's head: Placing a folded blanket or soft material under the child's head is a safe action to prevent injury during a tonic-clonic seizure. It helps protect the head from hitting the floor or any hard surfaces during the seizure.
C. Prevent movement of the child's extremities: It is not recommended to try to prevent movement of the child's extremities during a tonic-clonic seizure. Trying to restrain or hold the child down can cause injury. The goal is to ensure the child’s safety and prevent injury.
D. Put a tongue blade between the child's teeth: Inserting a tongue blade between the child’s teeth is dangerous and should never be done. It could lead to injury, including broken teeth or damage to the child's mouth or throat.
Correct Answer is B
Explanation
A. Give the infant a bottle immediately before the infant's bedtime: Feeding the infant immediately before bedtime can increase the risk of reflux as lying down soon after feeding can worsen gastroesophageal reflux. The infant should be kept upright after feeding.
B. Keep the infant at a 30-degree angle for 1 hour following each feeding: Keeping the infant upright at a 30-degree angle for about 30 to 60 minutes after feeding can help prevent the contents of the stomach from refluxing into the esophagus.
C. Limit the infant's formula feedings to every 6 hr: Infants with gastroesophageal reflux typically need more frequent feedings, not less. Limiting feedings to every 6 hours is not appropriate for a 2-month-old infant. Frequent, smaller feedings may help manage reflux.
D. Change the infant's formula to a soy-based formula: Switching to a soy-based formula is not a standard treatment for gastroesophageal reflux unless there is a specific allergy or intolerance to cow's milk protein. This should only be done if directed by the healthcare provider.
