A nurse is assisting with the care of an infant who has heart failure. Which of the following actions should the nurse take?

Choice A rationale:
The Rotavirus vaccine is typically administered to infants, usually starting at 2 months of age, to protect against severe diarrhea and vomiting caused by rotavirus infection. However, the child in question is 11 years old, and the rotavirus vaccine is not recommended for administration at this age. The vaccine's protection window is within the infant and early childhood period, and the child would likely have received this vaccine earlier.
Choice B rationale:
Haemophilus influenzae type b (Hib) Hib vaccine is recommended as a series of doses to protect against Haemophilus influenzae type B infection, which can lead to severe illnesses like meningitis and pneumonia. While the child may have received this vaccine in infancy, a booster dose is often recommended around age 11 to ensure ongoing protection. This choice is correct for the given age group.
Choice C rationale:
Hepatitis A Hepatitis A vaccine is typically administered in two doses, with the first dose given at age 1 and the second dose administered at least 6 months later. The child in question is 11 years old, and assuming the child received the vaccine as per the standard schedule, there would be no need to administer this vaccine again.
Choice D rationale:
Human papillomavirus (HPV) HPV vaccine is recommended for adolescents to protect against several strains of the human papillomavirus that can lead to various cancers later in life. It's usually administered in a series of doses starting around age 11 or 12. However, the prompt states that the child is already up-to-date with current immunizations, and if the child received the HPV vaccine at the appropriate age, there would be no need for another dose at this time.

Choice A rationale:
Lethargy, or extreme fatigue and sluggishness, is a characteristic symptom of hypothyroidism. Hypothyroidism occurs due to an underactive thyroid gland, which leads to a decrease in metabolic activity and energy levels. Children with hypothyroidism often exhibit lethargy, weakness, and a lack of interest in activities. This is due to the reduced metabolic rate and overall slowing down of bodily functions.
Choice B rationale:
Diarrhea is not a common finding associated with hypothyroidism. In fact, hypothyroidism tends to slow down gastrointestinal motility, leading to constipation rather than diarrhea. Therefore, diarrhea is not expected as a symptom in a child with hypothyroidism.
Choice C rationale:
Tachycardia, an elevated heart rate, is not typically associated with hypothyroidism. Instead, hypothyroidism often leads to bradycardia (a slower-than-normal heart rate) due to the overall slowing of the body's metabolic processes.
Choice D rationale:
Hirsutism, which refers to excessive hair growth in areas where hair growth is typically seen in males, is not a common finding in hypothyroidism. Hirsutism is more commonly associated with hormonal imbalances such as polycystic ovary syndrome (PCOS) rather than hypothyroidism.
