A mother has recently been informed that her child has Down syndrome. You will be assigned to care for the child at shift change. Which of the following characteristics is not associated with Down syndrome?

Correct Answer: C

Rationale: Individuals with Down syndrome commonly have certain physical characteristics, such as a simian crease (single transverse palmar crease), brachycephaly (shortened front-to-back skull dimension), and hypotonicity (low muscle tone). Oily skin is not a characteristic associated with Down syndrome; instead, individuals with Down syndrome often have dry skin. Therefore, oily skin is the correct answer in this context.

Correct Answer: A

Rationale: Green vegetables and liver are rich sources of folic acid. Green vegetables like spinach, asparagus, and broccoli are high in folic acid content. Liver, especially from chicken or beef, is also a good source of folic acid. Yellow vegetables and red meat (choice B) do not contain as high a concentration of folic acid as green vegetables and liver. Carrots (choice C) are nutritious but do not have the highest concentration of folic acid. Milk (choice D) is not a significant source of folic acid compared to green vegetables and liver.

Correct Answer: D

Rationale: The correct answer is Cl. difficile. Clostridium difficile (C. diff) is not typically associated with meningitis in humans. This bacterium is known to cause severe diarrhea, usually as a result of antibiotic treatment. S. pneumoniae, H. influenzae, and N. meningitidis are all known to be causative agents of meningitis in humans. S. pneumoniae is a common cause of bacterial meningitis, especially in adults. H. influenzae, particularly type b (Hib), used to be a leading cause of meningitis in children before the introduction of the Hib vaccine. N. meningitidis is another significant pathogen responsible for causing meningitis, especially in young adults and adolescents.

Correct Answer: D

Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.

Correct Answer: B

Rationale: The normal range of vital signs for pediatric patients varies with age. For 11 to 14-year-olds, the normal vital sign ranges are: Heart rate: 60-105 BPM; Respiratory rate: 12-20 RPM; Blood pressure: Systolic 85-120 mmHg, Diastolic 55-80 mmHg. The 13-year-old female in choice B has a diastolic blood pressure below the normal range, indicating hypotension. Additionally, her heart rate is at the upper limit of normal, and her respiratory rate is within normal limits. Choices A, C, and D all fall within the normal ranges for vital signs in pediatric patients.
