1. Which is the most frequently used test for measuring visual acuity?

• A. Snellen letter chart
• B. Ishihara vision test
• C. Allen picture card test
• D. Denver eye screening test

Correct answer: A

Rationale: The Snellen letter chart is the most commonly used test for measuring visual acuity, particularly in school-age children and adults.

2. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

3. The mother of a child with cognitive impairment calls the nurse because her son has been gagging and drooling all morning. The nurse suspects foreign body ingestion. What physiologic occurrence is most likely responsible for the presenting signs?

• A. Gastrointestinal perforation may have occurred.
• B. The object may have been aspirated.
• C. The object may be lodged in the esophagus.
• D. The object may be embedded in the stomach wall.

Correct answer: C

Rationale: The symptoms of gagging and drooling suggest that the foreign object is likely lodged in the esophagus. This can cause significant discomfort and potential complications, requiring immediate medical evaluation.

4. According to Erikson’s theory of psychosocial development, the school-age child is in which stage?

• A. Industry vs. inferiority
• B. Autonomy vs. shame and doubt
• C. Identity vs. role diffusion
• D. Trust vs. mistrust

Correct answer: A

Rationale: The correct answer is A: 'Industry vs. inferiority.' According to Erikson’s theory, school-age children (approximately 6-12 years old) are in the stage of industry vs. inferiority. In this stage, children focus on developing a sense of competence and productivity. Choice B, 'Autonomy vs. shame and doubt,' is incorrect as it refers to the stage that occurs during early childhood (1-3 years old). Choice C, 'Identity vs. role diffusion,' pertains to adolescence (12-18 years old). Choice D, 'Trust vs. mistrust,' is related to the stage of infancy (0-1 year old). Therefore, option A is the most appropriate stage for school-age children in Erikson's theory.

5. A child with acute gastrointestinal bleeding is admitted to the hospital. The nurse observes which sign or symptom as an early manifestation of shock?

• A. Restlessness
• B. Rapid capillary refill
• C. Increased temperature
• D. Increased blood pressure

Correct answer: A

Rationale: Restlessness is an early sign of shock due to decreased perfusion and oxygenation to the brain. This symptom requires immediate attention to prevent the progression to more severe stages of shock. Rapid capillary refill (Choice B) is not typically an early sign of shock but rather a sign of adequate perfusion. Increased temperature (Choice C) may occur in later stages of shock due to the body's response to stress. Increased blood pressure (Choice D) is not an early sign of shock; in fact, blood pressure tends to decrease in shock as a compensatory mechanism.
