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 D
Explanation
A. Lack of subcutaneous fat: Lack of subcutaneous fat may indicate neglect or malnutrition, but it is not a specific sign of sexual abuse.
B. Unexplained illness: Unexplained illness could be related to various conditions, including neglect or medical issues, but it is not a specific indicator of sexual abuse.
C. Poor personal hygiene: Poor personal hygiene can be a sign of neglect but does not directly point to sexual abuse. It could be due to lack of supervision, resources, or care rather than abuse.
D. Recurrent urinary tract infections: Recurrent urinary tract infections (UTIs) can be a red flag for sexual abuse, especially in young children. These infections may be caused by inappropriate sexual contact or injury to the genital area.
Correct Answer is A
Explanation
A. Implementing droplet precautions: Pertussis (whooping cough) is highly contagious and spreads through respiratory droplets. Implementing droplet precautions is essential to prevent the transmission of the infection to others, especially in a school-age child.
B. Obtaining a nasopharyngeal culture: While obtaining a culture is important for confirming the diagnosis of pertussis, the priority is to prevent the spread of the disease to others. Droplet precautions should be implemented immediately to reduce transmission.
C. Encouraging family members' compliance with antibiotic therapy: Antibiotic therapy is important for treating pertussis, but this is secondary to preventing the spread of infection. Once precautions are in place, encouraging adherence to the prescribed antibiotic regimen is necessary for the child's recovery.
D. Offering small amounts of oral fluids frequently: Maintaining hydration is important for a child with pertussis, especially as coughing can cause discomfort. However, the priority action is preventing the spread of the infection through droplet precautions.
