A nurse is reinforcing teaching with an adolescent client about the purpose of the glycosylated hemoglobin (HbA1c) test. Which of the following descriptions should the nurse include in the teaching?

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.

A. Collect a stool specimen for occult blood: A stool specimen for occult blood is typically used to check for hidden blood in the stool, which might suggest conditions like gastrointestinal bleeding or certain infections. It is not the primary test for diagnosing C. difficile infection.

B. Draw a blood culture: Blood cultures are used to identify bacteria or other pathogens in the blood, but they are not appropriate for diagnosing Clostridium difficile infection, which primarily affects the gastrointestinal system.

C. Conduct a tape test: A tape test is used for diagnosing pinworm infections, not for Clostridium difficile. It involves placing a piece of tape on the child's anal area to collect eggs for examination under a microscope. It is not relevant to the suspicion of C. difficile.

D. Obtain a stool specimen for culture: The most appropriate action is to collect a stool specimen for culture to identify C. difficile. The diagnosis of C. difficile infection is typically confirmed by stool testing, which may include testing for toxins produced by the bacteria.
