Question 1 of 9
What is the first sign of puberty in girls?
Correct Answer: C
Rationale: The correct answer is C, Thelarche. Thelarche refers to the onset of breast development, which is typically the first sign of puberty in girls. This occurs before menarche (the first menstrual period). Choices A and B, acne and hair growth in the pubic area and underarms, are not the first signs of puberty in girls. While acne can be a common occurrence during puberty, it usually appears after other physical changes. Hair growth in the pubic area and underarms also occurs later in the puberty process.
Question 2 of 9
What is the most critical physiologic change required of newborns at birth?
Correct Answer: A
Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The onset of breathing is the most immediate and critical physiologic change required for the transition to extrauterine life. Factors that interfere with this normal transition increase fetal asphyxia, which is a condition of hypoxemia, hypercapnia, and acidosis. While body temperature maintenance, stabilization of fluid and electrolytes, and closure of fetal shunts in the heart are crucial changes in the transition to extrauterine life, breathing and the exchange of oxygen for carbon dioxide must take precedence as they are essential for newborn survival.
Question 3 of 9
A young mother asks if her 9-month-old can begin drinking cow's milk instead of formula. You explain that:
Correct Answer: B
Rationale: Breast milk or formula should be used for now because whole cow's milk is not recommended for infants under 1 year. Cow's milk is not suitable for infants under 1 year of age as it lacks essential nutrients like iron and can lead to iron deficiency. Therefore, it is important to continue with breast milk or formula to ensure the baby's nutritional needs are met. Choice A is incorrect as cow's milk is not easier to digest than formula for infants. Choice C is incorrect as the type of milk, whether whole or skim, is not the primary concern at this age. Choice D is incorrect as cow's milk can actually increase the risk of iron deficiency anemia in infants.
Question 4 of 9
What is a physical characteristic of infants whose mothers smoked during pregnancy?
Correct Answer: D
Rationale: The correct answer is D: Growth restriction in weight, length, and chest and head circumference. Infants born to mothers who smoke during pregnancy exhibit growth failure in weight, length, chest, and head circumference. This growth failure is directly related to the number of cigarettes smoked by the mother. Choices A, B, and C are incorrect because infants exposed to maternal smoking do not tend to be large for gestational age, experience growth restriction in weight only, or be preterm but size appropriate for gestational age.
Question 5 of 9
What condition is often associated with severe diarrhea?
Correct Answer: A
Rationale: Severe diarrhea can lead to a loss of bicarbonate, resulting in metabolic acidosis. This is a common complication of prolonged or severe diarrhea, especially in children.
Question 6 of 9
Clinical manifestations of sodium excess (hypernatremia) include which signs or symptoms?
Correct Answer: D
Rationale: Hypernatremia often presents with dry, sticky mucous membranes due to dehydration. Hyperreflexia and abdominal cramps may also occur, but dry mucous membranes are more consistently observed in cases of sodium excess.
Question 7 of 9
A parent brings their 2-year-old son in for a well visit. The nurse assesses his growth since the last appointment. Which finding should concern the nurse?
Correct Answer: D
Rationale: The correct answer is D. A total weight gain of 15 lb in one year for a 2-year-old is excessive and may indicate an underlying issue such as a metabolic disorder or overfeeding. This rapid weight gain can put the child at risk for health problems. Choices A, B, and C are not typically concerning findings in a 2-year-old. A prominent abdomen can be normal at this age due to a toddler's slightly protruding belly, a forward curve of the spine at the sacral area is a typical finding in young children, and an increase in height of 5 inches in a year is within the expected range of growth for a 2-year-old.
Question 8 of 9
The nurse is caring for a child with suspected ingestion of some type of poison. What action should the nurse take next after initiating cardiopulmonary resuscitation (CPR)?
Correct Answer: D
Rationale: After ensuring the child's immediate survival needs are met with CPR, contacting poison control is critical to receive specific guidance on how to proceed with treatment. Other actions may be necessary depending on the situation but should follow contacting poison control.
Question 9 of 9
Picking up a pencil demonstrates the ability to use which of the following?
Correct Answer: A
Rationale: Picking up a pencil requires the use of the pincer grasp, which involves the coordination of the thumb and forefinger to hold small objects. The pincer grasp is a fine motor skill essential for tasks that necessitate precision and dexterity. Choices B, C, and D are incorrect. Prehension refers to the act of grasping or holding an object, parachute reflex is a protective response to sudden movement or loss of support, and grasp reflex is an automatic closing of the hand when an object is placed in the palm, none of which specifically relate to the action of picking up a pencil.
