1. What factor predisposes the urinary tract to infection in children?

• A. increased fluid intake
• B. short urethra in young girls
• C. prostatic secretions in males
• D. frequent emptying of the bladder

Correct answer: B

Rationale: The short urethra in young girls predisposes them to urinary tract infections. In young girls, the proximity of the urethra to the anus and the shorter urethra compared to boys make it easier for bacteria to travel up the urinary tract, increasing the risk of infection. Increased fluid intake and frequent emptying of the bladder are actually helpful in preventing urinary tract infections by flushing out bacteria. Prostatic secretions in males are not a factor in predisposing the urinary tract to infection in children.

2. An 8-year-old child with the diagnosis of meningitis is to have a lumbar puncture. What should the nurse explain is the purpose of this procedure?

• A. To measure the pressure of cerebrospinal fluid
• B. To obtain a sample of cerebrospinal fluid for analysis
• C. To relieve intracranial pressure
• D. To assess the presence of infection in the spinal fluid

Correct answer: B

Rationale: The primary purpose of a lumbar puncture is to obtain a sample of cerebrospinal fluid for analysis. This sample helps in diagnosing conditions such as meningitis by evaluating the presence of pathogens or abnormalities in the cerebrospinal fluid. Measuring the pressure of cerebrospinal fluid (Choice A) is not the main objective of a lumbar puncture, although it can be done during the procedure. Relieving intracranial pressure (Choice C) is not the direct purpose of a lumbar puncture, as other interventions are typically used for this purpose. Assessing the presence of infection in the spinal fluid (Choice D) is related to the overall goal of obtaining a sample for analysis, making it a secondary outcome of the procedure.

3. Which best describes a full-thickness (third-degree) burn?

• A. Erythema and pain
• B. Skin showing erythema followed by blister formation
• C. Destruction of all layers of skin evident with extension into subcutaneous tissue
• D. Destruction injury involving underlying structures such as muscle, fascia, and bone

Correct answer: C

Rationale: The correct answer is C: Full-thickness burns involve the destruction of all layers of skin, extending into the subcutaneous tissue. This type of burn causes severe damage and loss of sensation due to nerve destruction. Choice A, erythema and pain, describes superficial burns (first-degree). Choice B, skin showing erythema followed by blister formation, describes partial-thickness burns (second-degree). Choice D, destruction injury involving underlying structures such as muscle, fascia, and bone, goes beyond the description of full-thickness burns.

4. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence and beyond.
• B. The process occurs in a cephalocaudal (head-to-toe) pattern.
• C. Myelination decreases the speed of nerve impulses.
• D. Myelination decreases the specificity of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

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.
