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.

Explanation
Rationale for Correct Choices:
- Blood pressure: The adolescent's blood pressure has decreased significantly from 116/60 mm Hg to 88/50 mm Hg, indicating hypotension. This is a priority, as low blood pressure can lead to poor perfusion of vital organs and can worsen the overall condition. Immediate action, such as fluid resuscitation, is necessary.
- Temperature: The adolescent has a persistent high fever (39°C or 102.2°F), which needs to be managed to prevent complications such as febrile seizures or increased intracranial pressure, especially given the suspected meningitis. Fever management will help improve comfort and reduce metabolic demand on the body.
Rationale for Incorrect Choices:
- Nausea: While nausea is an uncomfortable symptom, it is not as urgent as hypotension. Managing blood pressure and stabilizing the adolescent's circulation takes priority before addressing nausea.
- Level of consciousness: The adolescent is lethargic but responsive to verbal stimuli. While their level of consciousness is important to monitor, it is primarily related to the underlying infection (likely meningitis). Stabilizing blood pressure and fever should be prioritized.
- Abdominal findings: The adolescent's abdominal findings (soft, flat abdomen with active bowel sounds) are not immediately concerning. The priority is managing the acute symptoms related to suspected meningitis and hypotension, rather than abdominal issues.
Correct Answer is B
Explanation
A. “I will push the medication to the back of my baby's mouth quickly using a syringe":
Pushing medication to the back of the mouth quickly could cause the baby to gag or choke. It’s better to administer the medication slowly to ensure the baby swallows it safely.
B. "I will gently squeeze my baby's cheeks when giving the medication.": Gently squeezing the baby's cheeks helps guide the baby to open their mouth and accept the medication. This ensures safe administration of oral medications without causing discomfort or distress.
C. "I will add the medication to 8 ounces of formula": Adding medication to formula is not recommended as it can alter the medication's effectiveness and make it harder to ensure the correct dosage. It is better to give the medication separately from formula.
D. "I will mix the medication in a 4-ounce bowl of rice cereal at breakfast": Mixing the medication with rice cereal could lead to the baby not receiving the full dose if they do not finish the cereal. Medications should generally be administered separately to ensure the full dose is given.
