The nurse is caring for an infant who weighs 16 kg. Calculate the daily maintenance fluid requirement for this child. Round to the nearest whole number.

Choice A reason: Cushing's syndrome is caused by excess cortisol, a type of glucocorticoid hormone, in the body. This can result from overproduction of cortisol by the adrenal glands, or from prolonged use of corticosteroid medications. Elevated glucocorticoid level is the correct alteration in endocrine function for this condition.

Choice B reason: Decreased aldosterone level is not related to Cushing's syndrome. Aldosterone is another hormone produced by the adrenal glands, but it regulates the balance of sodium and potassium in the body. Decreased aldosterone level can cause low blood pressure, dehydration, and electrolyte imbalance.

Choice C reason: Elevated aldosterone secretion is also not related to Cushing's syndrome. Elevated aldosterone secretion can cause high blood pressure, fluid retention, and hypokalemia (low potassium level). This condition is known as hyperaldosteronism or Conn's syndrome.

Choice D reason: Diminished glucocorticoid level is the opposite of Cushing's syndrome. Diminished glucocorticoid level can cause low blood sugar, fatigue, weight loss, and poor stress response. This condition is known as Addison's disease or adrenal insufficiency.

Choice A reason: This statement is false. A sugar-water pacifier does not help the vaccination be more effective. Vaccinations are effective because they stimulate the immune system to produce antibodies against a specific disease.

Choice B reason: This statement is false. A sugar-water pacifier does not prevent hypoglycemia from the stress of the injection. Hypoglycemia is a condition where the blood sugar level is too low, which can cause symptoms such as sweating, trembling, confusion, or seizures. A sugar-water pacifier does not provide enough glucose to prevent hypoglycemia.

Choice C reason: This statement is false. A sugar-water pacifier does not provide additional calories to prevent malnourishment. Malnourishment is a condition where the body does not get enough nutrients, such as protein, vitamins, and minerals, to function properly. A sugar-water pacifier does not provide enough nutrients to prevent malnourishment.

Choice D reason: This statement is true. A sugar-water pacifier soothes and distracts the infant from pain. Sugar-water has a sweet taste that activates the endorphin system, which reduces pain perception. A pacifier also provides oral stimulation and comfort, which distracts the infant from the pain of the injection.
