A goiter is an enlargement or hypertrophy of which gland?
Thyroid.
Posterior pituitary.
Adrenal.
Anterior pituitary.
The Correct Answer is A
Choice A rationale:
A goiter refers to the enlargement or hypertrophy of the thyroid gland. This can occur due to various reasons, such as iodine deficiency, autoimmune disorders like Hashimoto's thyroiditis, or Graves' disease (which is associated with hyperthyroidism). The thyroid gland produces hormones that regulate metabolism and growth, and when it becomes enlarged, it can lead to visible swelling in the neck.
Choice B rationale:
The posterior pituitary gland is responsible for the release of hormones like vasopressin (antidiuretic hormone) and oxytocin. A goiter is not associated with the posterior pituitary gland. Issues with the posterior pituitary can lead to problems with water balance and uterine contractions, but not thyroid enlargement.
Choice C rationale:
The adrenal glands are responsible for producing hormones like cortisol and adrenaline. While adrenal disorders can lead to various hormonal imbalances, a goiter is not related to adrenal gland function. Adrenal issues might cause symptoms like fatigue, weight changes, and blood pressure irregularities.
Choice D rationale:
The anterior pituitary gland produces hormones that regulate the functions of other endocrine glands, including the thyroid gland. However, a goiter is not directly associated with the anterior pituitary. The anterior pituitary's malfunction can result in disorders like growth hormone deficiency or Cushing's disease, but not thyroid enlargement.

Correct Answer is C
Explanation
The correct answer is choice C. Therapeutic management includes administration of gamma globulin and aspirin.
Choice A rationale:
The child's fever in Kawasaki disease is not usually responsive to antibiotics within 48 hours. Kawasaki disease is an inflammatory condition of blood vessels, and it doesn't typically respond to antibiotics. The fever associated with Kawasaki disease often persists even with appropriate treatment, and the management focuses on reducing inflammation and preventing complications.
Choice B rationale:
Aspirin is not contraindicated in Kawasaki disease. In fact, aspirin is a key component of the therapeutic management of Kawasaki disease. It is used to reduce inflammation and prevent the development of coronary artery aneurysms, a severe complication of the disease. However, the dosing of aspirin in Kawasaki disease is different from its use for pain relief, and it should be administered under medical supervision.
Choice C rationale:
Therapeutic management of Kawasaki disease does include administration of gamma globulin and aspirin. Gamma globulin is given to reduce the risk of coronary artery involvement and aneurysm formation. Aspirin, at a specific dose regimen, is used to decrease inflammation and platelet aggregation, thus preventing clot formation in the coronary arteries.
Choice D rationale:
The principal area of involvement in Kawasaki disease is not the joints. Kawasaki disease primarily affects the blood vessels, particularly the coronary arteries. The inflammation of these arteries can lead to the development of coronary artery aneurysms, which is a critical concern in Kawasaki disease. Joint involvement is not a prominent feature of this condition.
Correct Answer is C
Explanation
The correct answer is choice C. After taking antibiotics for 24 hours.
Choice A rationale:
Returning to school if no complications develop is not a sufficient guideline for allowing a child with streptococcal pharyngitis to return to school. Streptococcal pharyngitis (strep throat) is highly contagious, and children should be treated with antibiotics to prevent the spread of the infection.
Choice B rationale:
Waiting until the sore throat is better is not a specific enough criterion for returning to school. While the resolution of symptoms is an important factor, it's crucial to ensure that the child has also been on antibiotics for an appropriate duration to reduce the risk of spreading the infection to others.
Choice C rationale:
The recommended guideline is to return to school after taking antibiotics for 24 hours. This timeframe helps ensure that the child's contagiousness is significantly reduced, minimizing the risk of transmitting the infection to classmates and school staff.
Choice D rationale:
Waiting for three days after taking antibiotics is not as precise as waiting for 24 hours. With proper antibiotic treatment, the child's contagiousness decreases rapidly, and waiting for three days might be unnecessary and could potentially result in more missed school days than needed.
