Why is it difficult to assess a child's dietary intake?

Correct Answer: D

Rationale: The correct answer is D. Recall of food intake, especially amounts eaten, is often unreliable. While systematic tools like the 24-hour recall and dietary history questionnaires exist, recall can still be challenging in accurately assessing a child's dietary intake. Choices A, B, and C are incorrect because systematic assessment tools do exist, biochemical analysis is not the primary method for dietary assessment, and families' understanding of nutrition may vary but is not the main reason for the difficulty in assessing a child's dietary intake.

Correct Answer: A

Rationale: The correct answer is A: 'May reduce pain perception.' When teaching parents about nonpharmacologic strategies for pain management in children, the nurse should include information that these techniques may help reduce pain perception, make the pain more tolerable, decrease anxiety, and enhance the effectiveness of analgesics. It is important to note that nonpharmacologic techniques should be learned before the pain occurs, and it is beneficial to use both pharmacologic and nonpharmacologic measures for pain control. Choice B is incorrect because nonpharmacologic strategies do not make pharmacologic strategies unnecessary but rather complement them. Choice C is incorrect as nonpharmacologic techniques, when properly learned and applied, do not usually take too long to implement. Choice D is incorrect as the goal of nonpharmacologic strategies is not to trick children into believing they do not have pain, but to help them cope with and manage their pain effectively.

Correct Answer: C

Rationale: For severe postoperative pain, a preventive around-the-clock schedule is necessary to prevent decreased plasma levels of medications. Providing only an opioid analgesic at this time may not be sufficient for effective pain management. Increasing the dosage without an order is unsafe and may lead to oversedation. Planning a preventive schedule of pain medication around the clock ensures consistent pain relief and better management. Giving the child a clock and explaining when they can have pain medications may increase the child's focus on waiting for relief rather than addressing the pain promptly, making it a less effective strategy.

Correct Answer: A

Rationale: The correct answer is A: 1 year. The hepatitis A vaccine is now recommended for all children starting at age 1 year (i.e., 12 to 23 months). This is due to the recognition of hepatitis A as a significant child health problem, especially in areas with high infection rates. The virus is primarily spread through fecal-oral transmission, person-to-person contact, ingestion of contaminated food or water, and rarely through blood transfusion. Administering the first dose at 1 year helps protect children from this infection. Choices B and C are incorrect as the vaccine is not recommended at 1 month or 12 years. Choice D is also incorrect as the hepatitis A vaccine is recommended at a specific age to prevent the infection.

Correct Answer: B

Rationale: The correct answer is B: Chickenpox. Chickenpox is highly infectious and is transmitted through direct contact, droplet spread, and contaminated objects. Due to its high communicability, strict isolation of the patient is necessary to prevent the spread of the disease. Mumps is primarily transmitted through direct contact with the infected person's saliva, with peak contagiousness before the onset of swelling. Exanthema subitum (roseola) has an unknown transmission source. Erythema infectiosum (fifth disease) is contagious before the appearance of symptoms. Therefore, these diseases do not require the same level of strict isolation as chickenpox.
