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. Clinical manifestations of sodium excess (hypernatremia) include which signs or symptoms?

• A. Hyperreflexia
• B. Abdominal cramps
• C. Cardiac dysrhythmias
• D. Dry, sticky mucous membranes

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.

3. What is the recommended position for a child after a tonsillectomy?

• A. Supine
• B. Prone
• C. Side-lying
• D. Fowler's position

Correct answer: C

Rationale: The correct answer is C: Side-lying. The side-lying position is recommended after a tonsillectomy to facilitate drainage of secretions and reduce the risk of aspiration. This position helps prevent blood from pooling in the back of the throat, decreasing the chance of bleeding postoperatively. Supine (lying face up), while commonly used in other situations, may not be ideal immediately after a tonsillectomy due to the risk of airway obstruction from blood clots. Prone (lying face down) is not recommended as it can hinder breathing and increase the risk of complications. Fowler's position (semi-sitting) is also not typically used after a tonsillectomy because it may cause discomfort and hinder proper drainage.

4. Melena, the passage of black, tarry stools, suggests bleeding from which source?

• A. The perianal or rectal area
• B. The upper gastrointestinal (GI) tract
• C. The lower GI tract
• D. Hemorrhoids or anal fissures

Correct answer: B

Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.

5. The nurse is caring for a child with Beta Thalassemia. Which child is in a group most at risk for Beta Thalassemia?

• A. A three-year-old girl of Mediterranean descent.
• B. A ten-year-old boy of Hispanic descent.
• C. A young girl of African descent.
• D. A baby of European descent.

Correct answer: A

Rationale: Corrected Rationale: Beta Thalassemia is most common in individuals of Mediterranean descent, such as those from Italy, Greece, and the Middle East. This genetic disorder affects hemoglobin production and can lead to severe anemia. Choice A is the correct answer as individuals of Mediterranean descent are at the highest risk for Beta Thalassemia. Choices B, C, and D are incorrect as they do not belong to the population group most at risk for this genetic disorder.
