1. An order is written for an isotonic enema for a 2-year-old child. What is the maximum amount of fluid the nurse should administer without a specific order from the health care provider?

• A. 100 to 150 mL
• B. 155 to 250 mL
• C. 255 to 360 mL
• D. 365 to 500 mL

Correct answer: B

Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL to prevent overdistension and potential harm. Choice A (100 to 150 mL) is too low and may not be effective in achieving the desired outcome. Choices C (255 to 360 mL) and D (365 to 500 mL) exceed the safe range for a 2-year-old child and can lead to overdistension, electrolyte imbalance, or other complications. Therefore, the correct answer is B.

2. The instructor is educating 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.
• B. The process occurs in a head-to-toe fashion.
• C. Myelination speeds up nerve impulses.
• D. Myelination increases the specificity and efficiency 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 because myelination continues beyond 4 years of age and into adolescence. Choice C is incorrect as myelination speeds up nerve impulses rather than slowing them down. Choice D is incorrect because myelination increases the specificity and efficiency of nerve impulses, making them more focused and precise.

3. The parents of an infant ask the nurse why their baby is scheduled to receive the intramuscular polio vaccine rather than the oral vaccine. What is the nurse’s best response?

• A. The American Academy of Pediatrics recommends the intramuscular vaccine because it is safer.
• B. The consensus is that either can be used, since both produce the same results and are equally safe.
• C. The oral vaccine is more expensive, so the intramuscular vaccine is preferred unless it is contraindicated.
• D. The U.S. Centers for Disease Control and Prevention recommends the intramuscular vaccine unless the infant or a family member is immunocompromised.

Correct answer: A

Rationale: The American Academy of Pediatrics recommends the intramuscular polio vaccine because it has a better safety profile compared to the oral vaccine. Choice B is incorrect because the AAP specifically recommends the intramuscular vaccine over the oral vaccine. Choice C is incorrect as cost is not the primary reason for preferring the intramuscular vaccine. Choice D is incorrect as the recommendation is based on safety rather than the immunocompromised status of the infant or family members.

4. Why should the nurse closely monitor the IV flow rate for a 5-month-old infant with severe diarrhea receiving IV fluids?

• A. Maintaining electrolyte balance
• B. Preventing dehydration
• C. Preventing fluid overload
• D. Avoiding cardiac overload

Correct answer: C

Rationale: In infants, monitoring IV flow rates is essential to prevent fluid overload, not cardiac overload. Excessive fluid administration can lead to complications such as pulmonary edema or congestive heart failure. It is crucial to maintain a balance between providing adequate hydration and avoiding fluid overload to prevent adverse outcomes. Options A, B, and D are incorrect because the primary concern is to prevent complications related to excess fluid rather than focusing on electrolyte balance, dehydration prevention, or avoiding cardiac overload.

5. A child has been admitted to the pediatric unit with a severe asthma attack. What type of acid-base imbalance should the nurse expect the child to develop?

• A. metabolic alkalosis due to insufficient production of acid metabolites
• B. respiratory alkalosis due to depressed respirations and retention of carbon dioxide
• C. respiratory acidosis due to impaired respirations and increased formation of carbonic acid
• D. metabolic acidosis due to the kidneys' inability to compensate for decreased carbonic acid formation

Correct answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis. This occurs due to impaired respirations, leading to the retention of carbon dioxide and the formation of carbonic acid. Choice A is incorrect as metabolic alkalosis is not expected in this situation. Choice B is incorrect as respiratory alkalosis does not align with the scenario of impaired respirations in severe asthma attacks. Choice D is also incorrect as it describes metabolic acidosis, which is not typically associated with severe asthma attacks.
