An infant with tetralogy of Fallot becomes cyanotic and dyspneic after a crying episode. To relieve the cyanosis and dyspnea, the nurse should place the infant in the:

Correct Answer: A

Rationale: The orthopneic position is the best position to relieve cyanosis and dyspnea in an infant with tetralogy of Fallot. This position involves sitting up and leaning forward, which helps improve lung expansion and oxygenation. Placing the infant in the orthopneic position will reduce the workload on the heart, improve oxygenation, and relieve symptoms of cyanosis and dyspnea associated with tetralogy of Fallot. It allows for better expansion of the lungs and improves ventilation-perfusion matching, thereby enhancing oxygen exchange and alleviating the cyanotic spell.

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: C

Rationale: A newborn with meningomyelocele should be placed in a prone position to prevent trauma or pressure on the lesion. Placing the newborn in the prone position helps prevent the lesion from coming in contact with surfaces and reduces the risk of infection and injury. By positioning the newborn prone, gravity will assist in closing the lesion and reducing the risk of complications. It is crucial to follow this positioning guideline to ensure the infant's safety and well-being.

Correct Answer: A

Rationale: Monitoring head circumference is essential in children with meningitis to assess for possible development of hydrocephalus. Hydrocephalus is a potentially serious complication that can occur following meningitis. An increase in head circumference can indicate the accumulation of cerebrospinal fluid in the brain due to hydrocephalus. Regularly measuring the head circumference allows healthcare providers to detect any early signs of hydrocephalus and take appropriate actions such as further imaging or intervention. Monitoring for convulsions, assessing pupil size, and watching for vomiting are important aspects of care for a child with meningitis but are not specific to monitoring for hydrocephalus.

Correct Answer: B

Rationale: Strabismus, or misalignment of the eyes, is a common condition in newborns due to the lack of binocularity. Binocularity refers to the ability of both eyes to focus simultaneously on a single point, which is not fully developed in newborns. As a result, it is normal for a newborn's eyes to appear misaligned at times. This lack of coordination between the eyes typically resolves as the infant's visual system matures and they develop the ability to focus both eyes together. Therefore, the presence of strabismus in a newborn is usually considered a normal finding related to the immature visual development rather than a sign of pathology such as congenital cataracts, absence of red reflex, or pupil reactivity issues.
