An infant with a diagnosis of hydrocephalus is scheduled for surgery. Which is the priority nursing intervention in the preoperative period?

A. Orthopnea
Explanation:
Orthopnea refers to difficulty breathing that occurs when lying flat. In heart failure, fluid may accumulate in the lungs, leading to respiratory distress when the child is in a supine position. Orthopnea is a common symptom of heart failure in both adults and children.
B. Bradycardia
Explanation: Bradycardia (slow heart rate) is not a typical finding in heart failure. Heart failure often leads to compensatory mechanisms, including an increased heart rate (tachycardia), to maintain cardiac output.
C. Weight loss
Explanation: Weight loss is not a typical finding in heart failure. In fact, heart failure in children may lead to fluid retention and weight gain rather than weight loss.
D. Increased urine output
Explanation: Heart failure in toddlers is more likely to be associated with decreased urine output rather than increased urine output. Reduced cardiac output can result in decreased blood flow to the kidneys, leading to decreased urine production and potential fluid retention. Increased urine output is not a characteristic finding in heart failure.

A. Changes in the voice signal the beginning of puberty.
Explanation: Changes in the voice, specifically deepening, are associated with puberty, but they typically occur later in puberty. The voice change is related to the growth of the larynx (Adam's apple) and tends to happen after other physical changes.
B. Gynecomastia commonly occurs during late puberty.
Explanation:
Gynecomastia, the development of breast tissue in males, is a common occurrence during puberty. It is often temporary and tends to happen during late puberty. The enlargement of breast tissue can be a source of concern for adolescent boys, and providing information about the normalcy and temporary nature of gynecomastia can be reassuring for both parents and boys.
C. Puberty might be delayed if scrotal changes have not occurred by the age of 11 years.
Explanation: The timing of pubertal changes can vary among individuals. While certain age ranges are provided as general guidelines, the absence of scrotal changes by a specific age does not necessarily indicate delayed puberty. Puberty is a gradual process with individual variations.
D. Growth spurts in height occur toward the end of midpuberty.
Explanation: Growth spurts in height, known as the adolescent growth spurt, typically occur during midpuberty. This phase is marked by rapid growth in height, changes in body composition, and the development of secondary sexual characteristics.
