What is the most appropriate nursing action when intermittently gavage feeding a preterm infant?

Correct Answer: A

Rationale: The correct action when intermittently gavage feeding a preterm infant is to allow the formula to flow by gravity. This method helps prevent overfeeding and aspiration, which can occur if the formula is delivered too quickly under pressure. Choice B is incorrect as sucking on the tube can cause complications. Choice C is incorrect as the tube is typically inserted through the mouth. Choice D is incorrect as steady pressure can lead to rapid delivery of the formula, increasing the risk of complications.

Correct Answer: A

Rationale: Physiologic manifestations of pain may vary considerably, so they do not provide a consistent measure of pain. Heart rate may increase or decrease. The same signs that may suggest fear, anxiety, or anger also indicate pain. In chronic pain, the body adapts, and these signs decrease or stabilize. Physiologic measurements are of limited value and must be viewed in the context of a pain rating scale, behavioral assessment, and parental report. When the child reports pain on an appropriate pain scale, the appropriate interventions should be used. Therefore, physiologic measurements are not considered a reliable standalone indicator for pain in children, making choice A the correct answer. Choice B is incorrect because physiologic measurements alone do not serve as the best indicator of pain. Choice C is incorrect as physiologic measurements are still limited even when children report pain. Choice D is incorrect as physiologic measurements are not primarily used to determine the truthfulness of a child's pain report.

Correct Answer: C

Rationale: The correct answer is C because the PCA pump can be programmed to deliver a continuous basal rate of pain medication to maintain pain control. While the goal of PCA is effective pain relief, it does not guarantee a pain-free state. In the case of a 5-year-old child, the parents or nurse can administer boluses if necessary since the child may not fully comprehend using the PCA button. Monitoring every 1 to 2 hours for patient response is adequate and there is no need for monitoring every 15 minutes, as stated in choice D, unless specific circumstances dictate more frequent monitoring.

Correct Answer: B

Rationale: If the mother is HBsAg negative, it is recommended that the child receives the first dose of the hepatitis B vaccine at birth before discharge from the hospital. This is to provide early protection against the hepatitis B virus. The second dose of the vaccine is typically given at the first well-child visit, and the third dose is usually administered at a later date. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the Committee on Infectious Diseases of the American Academy of Pediatrics govern the recommendations for immunization, including the hepatitis B virus vaccine. Choice A is incorrect as the first dose should ideally be given at birth. Choice C is incorrect as waiting until 6 months of age may leave the child vulnerable to infection during the early months of life. Choice D is incorrect as the hepatitis B vaccine is recommended for all newborns, especially if the mother is HBsAg negative, to prevent transmission of the virus.

Correct Answer: B

Rationale: The correct answer is B: Stethoscope. A stethoscope is commonly used between patients, and if not correctly disinfected, it can be a dangerous source of spreading microorganisms. Thermometers typically have barriers to prevent this type of transmission. Injection needles are discarded immediately after use and not reused, making them an unlikely source of transmission. Similarly, disposable gloves are not reused, so they are also not a common source of harmful microorganism transmission.
