1. What is the most critical physiological change required of newborns at birth?

• A. Transition from fetal to neonatal breathing
• B. Body temperature maintenance
• C. Stabilization of fluid and electrolytes
• D. Closure of fetal shunts in the heart

Correct answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The most critical physiological change required of newborns at birth is the initiation of breathing. This transition is crucial for the newborn to start exchanging oxygen and carbon dioxide outside the womb, marking the beginning of their independent respiratory function. Choices B, C, and D are important aspects of newborn care but are not as immediately critical as the establishment of breathing for oxygenation and removal of carbon dioxide, which is essential for the newborn's survival and adaptation to extrauterine life.

2. An effective means of establishing rapport with the hospitalized pre-schooler is through:

• A. Lengthy discussion
• B. Explanation with drawings and models
• C. Play
• D. Silence

Correct answer: C

Rationale: Play is an effective way to communicate and build rapport with young children, especially pre-schoolers. It helps them feel comfortable, express themselves, and establish a connection with the caregiver. Lengthy discussions may not be suitable for their age and attention span, while explanation with drawings and models can enhance communication but may not engage them as effectively as play. Silence, on the other hand, may create a sense of unease or lack of interaction for pre-schoolers.

3. A child is hospitalized in acute renal failure and has a serum potassium greater than 7 mEq/L. What temporary measures that will produce a rapid but transient effect to reduce the potassium should the nurse expect to be prescribed? (Select all that apply.)

• A. Dialysis
• B. All below
• C. Sodium bicarbonate
• D. Glucose 50% and insulin

Correct answer: A

Rationale: Calcium gluconate, sodium bicarbonate, and glucose with insulin are used as temporary measures to rapidly reduce serum potassium levels. They help shift potassium into cells and stabilize the heart but do not remove potassium from the body like dialysis does.

4. Which parental statement indicates correct understanding of information presented regarding the prevention of iron deficiency anemia in infants?

• A. "We will add green leafy vegetables to our child’s low-iron formula."
• B. "We will discontinue the use of vitamin C supplements by 6 months of age."
• C. "We will begin an iron-fortified infant cereal at 4 to 6 months of age."
• D. "We will introduce cow’s milk by 6 months of age."

Correct answer: C

Rationale: The correct answer is C. Introducing iron-fortified cereal between 4 to 6 months of age is a recommended practice to prevent iron deficiency anemia in infants. Iron-fortified infant cereals are a good source of iron for infants. Choices A and B are incorrect because adding green leafy vegetables to low-iron formula and discontinuing vitamin C supplements do not directly address the prevention of iron deficiency anemia. Choice D is incorrect because cow's milk should be avoided before 12 months of age as it is low in iron and can lead to intestinal blood loss, increasing the risk of iron deficiency anemia.

5. What is the narrowing of the preputial opening of the foreskin called?

• A. Chordee
• B. Phimosis
• C. Epispadias
• D. Hypospadias

Correct answer: B

Rationale: Phimosis is the condition where the foreskin cannot be fully retracted over the glans penis due to a narrowing of the preputial opening. Chordee, epispadias, and hypospadias are different conditions involving the penis's structure.
