When administering an I.M. injection to an infant, the nurse in charge should use which site?

Correct Answer: D

Rationale: When administering an intramuscular (I.M.) injection to an infant, the nurse should use the vastus lateralis muscle. This is the preferred site for infants as it provides a large muscle mass and is less likely to damage nerves and blood vessels compared to other sites. The vastus lateralis is located on the thigh and is easily accessible for injections in infants. It is important to select the appropriate site for I.M. injections in infants to ensure proper medication absorption and minimize the risk of complications.

Correct Answer: C

Rationale: Diabetes Insipidus (DI) is a condition characterized by the inability of the kidneys to conserve water, leading to excessive thirst and excretion of large volumes of dilute urine. Central DI, the most common form in children, is treated with a synthetic form of the hormone vasopressin, also known as desmopressin. Vasopressin helps the kidneys to retain water, thereby reducing urine output and preventing excessive dehydration. Since DI is a chronic condition, treatment with vasopressin is typically required on a lifelong basis to manage symptoms and prevent complications. It is important for healthcare providers to understand the long-term nature of DI treatment in order to provide appropriate care and support to patients with this condition.

Correct Answer: D

Rationale: The nurse should inform the mother that the baby can be discharged once the Plastibell rim falls off. The Plastibell method involves placing a small plastic ring over the foreskin, which cuts off circulation and causes the foreskin to fall off on its own within a week to 10 days after the procedure. Once the Plastibell rim has fallen off, it indicates that the circumcision site has healed, and the baby is ready to be discharged. The other options, such as the newborn voiding, receiving vitamin K, or yellow exudate forming over the glans, are important aspects of post-circumcision care but are not indicative of the baby being ready for discharge.

Correct Answer: C

Rationale: Diabetes insipidus is a condition characterized by excessive thirst and excretion of large amounts of dilute urine, resulting in fluid volume deficit. The posterior pituitary tumor in this case is likely causing decreased secretion of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine and retain water. This imbalance results in the loss of fluid, leading to dehydration and electrolyte imbalances. Therefore, the most appropriate nursing diagnosis for this client is fluid volume deficit, as the priority is to address the dehydration and restore fluid balance to prevent further complications.

Correct Answer: A

Rationale: The Kasai procedure is a palliative surgery for biliary atresia that helps restore bile flow and delays the need for liver transplantation.
