when a parent is holding the infant

During sleep

When changing the infant's diapers

When drawing blood for electrolyte level testing

Answer and Explanation

The Correct Answer is D

A. When a parent is holding the infant
Explanation: Being held by a parent is generally a comforting and calming experience for an infant, and it is unlikely to significantly increase oxygen demand. In fact, the presence of a familiar caregiver may help reduce stress.
B. During sleep
Explanation: During sleep, an infant's oxygen demand may decrease, and oxygen supplementation may not be necessary unless there are specific indications or concerns about oxygen saturation levels.
C. When changing the infant's diapers
Explanation: Changing a diaper is a routine care activity that is not likely to significantly increase oxygen demand. It is not typically associated with stress or increased metabolic activity that would necessitate additional oxygen.
D. When drawing blood for electrolyte level testing
Explanation:
Drawing blood for electrolyte level testing is a potentially stressful procedure that may cause distress and anxiety in the infant. Stress and anxiety can increase the metabolic rate and oxygen demand. In a situation where an infant is already prescribed oxygen as needed for heart failure, additional stressors like blood drawing may necessitate the administration of oxygen to ensure an adequate oxygen supply

Correct Answer is B

Explanation

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.

A. That lethargy and vomiting are normal with mumps B. To continue to monitor the child C. To bring the child to the clinic to be seen by the pediatrician D. That there is nothing to be concerned about as long as there is no fever

Correct Answer is C

Explanation

A. That lethargy and vomiting are normal with mumps:
Incorrect: Lethargy and vomiting are not typical symptoms of mumps. These symptoms could indicate a separate issue that requires medical attention.
B. To continue to monitor the child:
Incorrect: Given the reported symptoms of lethargy and vomiting, a passive approach of continuing to monitor may delay necessary medical intervention. The child should be assessed promptly.
C. To bring the child to the clinic to be seen by the pediatrician:
Correct Answer: Lethargy and vomiting are not typical symptoms of uncomplicated mumps. These symptoms could be indicative of other issues, and it's important for the pediatrician to evaluate the child to determine the cause and provide appropriate care.
D. That there is nothing to be concerned about as long as there is no fever:
Incorrect: While fever is a common symptom of mumps, the absence of fever does not negate the need for further evaluation when there are concerning symptoms like lethargy and vomiting. The child should be seen by a healthcare provider to determine the cause of these symptoms.
