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."

Answer and Explanation

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 D

Explanation

A. "You should position the car seat at a 30-degree angle." The correct angle for rear-facing car seats is 45 degrees. A 30-degree angle may cause the infant’s head to fall forward, increasing the risk of airway obstruction.
B. "You should place a folded blanket to pad the back of the infant's head." Extra padding behind or around the infant's head is not recommended as it may interfere with the seat’s effectiveness and safety in a crash.
C. "You should use a car seat with a four-point harness." The recommended harness system is a five-point harness, which provides more secure restraint at the shoulders, hips, and between the legs.
D. "You should place the retainer clip at the level of the infant's armpits." Correct placement of the retainer (chest) clip is at armpit level. This ensures that the harness straps stay positioned over the shoulders, reducing the risk of injury during a crash.

A. "There is nothing we can do to minimize overgrowth of their gum tissue." B. "They will need to take 400 IU of vitamin E while on this medication." C. "We will need to periodically have their blood drawn to check phenytoin levels." D. "This medication may cause their eyes to, at times, move quickly back and forth."

Correct Answer is ["C","D"]

Explanation

A. "There is nothing we can do to minimize overgrowth of their gum tissue.": Incorrect. Gingival hyperplasia is a known side effect of phenytoin, but good oral hygiene and regular dental care can help minimize its severity.
B. "They will need to take 400 IU of vitamin E while on this medication.": Incorrect. Routine vitamin E supplementation is not standard or necessary with phenytoin unless specifically indicated by a provider.
C. "We will need to periodically have their blood drawn to check phenytoin levels.": Correct. Phenytoin has a narrow therapeutic index, so serum drug levels must be monitored regularly to avoid toxicity or subtherapeutic dosing.
D. "This medication may cause their eyes to, at times, move quickly back and forth.": Correct. Nystagmus is a known dose-related side effect of phenytoin, especially at higher levels.
E. "This drug won't decrease the effectiveness of their oral contraceptive medication.": Incorrect. Phenytoin is a hepatic enzyme inducer and can reduce the effectiveness of hormonal contraceptives, so alternate or additional contraceptive methods should be recommended.
