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 C
Explanation
A. Reinforce with the guardians to avoid discussing death with the child's siblings: Avoiding the discussion of death with the child's siblings can create confusion and anxiety. It's important to foster open communication and allow siblings to process their emotions about the situation in an age-appropriate manner.
B. Guide discussions with the child about death: Discussions about death should be handled delicately, considering the child’s age and understanding; this should be done in partnership with the family and healthcare providers.
C. Use a calm tone of voice when speaking with the child: A calm, reassuring tone of voice is essential when interacting with a child in palliative care. This helps provide comfort, reduces anxiety, and establishes a sense of safety for the child during a difficult time.
D. Encourage the guardians to seek a second opinion about their child's diagnosis:
Seeking a second opinion may be an option in some situations, but in the context of palliative care, the focus is typically on comfort and quality of life rather than pursuing further curative treatments.
Correct Answer is C
Explanation
A. Temperature: A temperature of 38.6°C (101.5°F) is elevated, but fever is a common symptom of bacterial pneumonia. It is important to monitor, but it is not the most critical finding in this case.
B. Skin condition: Hives and flushing could be signs of an allergic reaction to medication, but this is not immediately life-threatening. The nurse should report it, but the priority in this case is the oxygen saturation, which reflects the patient's respiratory status.
C. Oxygen saturation: Oxygen saturation of 93% is below the typical threshold of 95-100% and indicates mild hypoxemia. In a patient with bacterial pneumonia, low oxygen saturation signify worsening respiratory function. This requires immediate attention and reporting.
D. Lung sounds: Coarse crackles in the right lower lobe are expected in pneumonia due to lung consolidation. While it is important to monitor lung sounds, the priority is addressing the oxygen saturation level, which is directly related to the patient's ability to breathe effectively.
