Why does the nurse have a 2-year-old boy sit in a "tailor" position while palpating for the presence of the testes?

Correct Answer: A

Rationale: The tailor position stretches the muscle responsible for the cremasteric reflex, preventing it from contracting and pulling the testes into the pelvic cavity. This position helps accurately palpate the testes. Choice B is incorrect because the position does not facilitate the palpation of undescended testes specifically. Choice C is incorrect as it does not relate to the rationale behind the tailor position. Choice D is incorrect as the reason for using the tailor position is not related to the child's need for privacy.

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.

Correct Answer: C

Rationale: The NCAST Feeding Scale is the most suitable tool to evaluate maternal and newborn attachment behaviors during feedings. It focuses on observing the interaction between the parent and infant, providing insights into their bonding. The Apgar score is used to assess a neonate's immediate transition to life outside the womb, not specifically maternal and newborn attachment behaviors. The Ballard scale is used to estimate gestational age, not to assess attachment behaviors. The Brazelton Neonatal Behavioral Assessment Scale is designed to evaluate a newborn's responses to various stimuli, not specifically maternal and newborn attachment behaviors.
