Nursing Elites

1. When evaluating the laboratory report of a 1-year-old infant’s hematocrit, a healthcare provider compares it with the expected hematocrit range for this age group. What is the hematocrit of a healthy 12-month-old infant?

• A. 19% to 32%
• B. 29% to 41%
• C. 37% to 47%
• D. 42% to 69%

Correct answer: C

Rationale: The correct hematocrit range for a healthy 12-month-old infant is between 37% to 47%. At this age, this range reflects the normal blood volume and red blood cell (RBC) levels in infants. Choice A (19% to 32%) is too low for a healthy hematocrit level in a 12-month-old. Choice B (29% to 41%) is also below the typical range for a 12-month-old. Choice D (42% to 69%) includes an upper limit that is higher than expected for a healthy infant, making it an incorrect option.

2. The nurse is reviewing the laboratory test results of a child diagnosed with disseminated intravascular coagulation (DIC). What would the nurse interpret as indicative of this disorder?

• A. Shortened prothrombin time
• B. Increased fibrinogen level
• C. Positive fibrin split products
• D. Increased platelets

Correct answer: C

Rationale: Positive fibrin split products are indicative of disseminated intravascular coagulation (DIC). In DIC, there is widespread clotting and subsequent consumption of clotting factors, leading to the formation of fibrin split products. A shortened prothrombin time (Choice A) is not typically seen in DIC as it indicates faster clotting, which is opposite to the pathophysiology of DIC. An increased fibrinogen level (Choice B) may be observed in the early stages of DIC due to the compensatory increase in production, but it is not a definitive indicator. Increased platelets (Choice D) may be seen in the early stages of DIC due to the body's attempt to compensate for clot formation, but it is not a specific finding for DIC.

3. A group of students is reviewing information about the endocrine system in infants and children. The students demonstrate understanding of the information when they state:

• A. Endocrine glands begin developing in the first trimester of gestation.
• B. At birth, the endocrine glands are not fully functional.
• C. Infants may have difficulty balancing glucose and electrolytes.
• D. A child’s endocrine system plays a vital role in growth and development.

Correct answer: C

Rationale: The correct statement is that infants may have difficulty balancing glucose and electrolytes because their endocrine systems are immature. Newborns have developing endocrine glands that are not yet fully functional, leading to challenges in maintaining glucose and electrolyte balance. Choice A is incorrect as endocrine glands start developing in the first trimester, not the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth. Choice D is incorrect because while a child’s endocrine system indeed plays a vital role in growth and development, the specific focus of the question is on the challenges infants face due to immature endocrine glands.

4. A nurse is teaching the parents of a toddler about the signs and symptoms of lead poisoning. Which symptom should the nurse emphasize?

• A. Abdominal pain
• B. Constipation
• C. Irritability
• D. Frequent urination

Correct answer: C

Rationale: Irritability is a significant symptom of lead poisoning in toddlers and should be emphasized to parents. Lead poisoning can manifest with various symptoms, but irritability is particularly common in children exposed to lead. Abdominal pain (Choice A) is not a typical symptom of lead poisoning in toddlers. While constipation (Choice B) can occur, it is less specific and less common than irritability. Frequent urination (Choice D) is not a typical symptom associated with lead poisoning in toddlers and is less relevant for parents to recognize in this context.

5. A major developmental milestone of a toddler is the achievement of autonomy. What should the caregiver instruct the parents to do to enhance their toddler’s need for autonomy?

• A. Teach the child to share with others.
• B. Help the child learn society’s roles.
• C. Teach the child to accept external limits.
• D. Help the child develop internal controls.

Correct answer: D

Rationale: Toddlers are striving for autonomy during this developmental stage. Helping the child to develop internal controls, such as self-regulation and decision-making skills, enhances their sense of autonomy. Choice A, teaching the child to share, focuses more on social skills rather than autonomy. Choice B, helping the child learn society's roles, pertains to socialization rather than autonomy. Choice C, teaching the child to accept external limits, is about compliance with rules rather than fostering autonomy. Therefore, the most appropriate action to enhance a toddler's need for autonomy is to help them develop internal controls.
