Correct Answer: A

Rationale: Keeping the infant away from people with colds is crucial to prevent the spread of respiratory infections, especially for infants recently hospitalized with bronchiolitis. This precaution helps protect the baby from further illnesses and promotes recovery. The other choices are incorrect because it is important to complete the prescribed medication course even if the baby seems better to ensure the infection is fully treated (Choice B). Solid foods are usually introduced around six months of age, so avoiding them entirely may not be necessary (Choice C). Placing the baby to sleep on their back is a safe sleep practice to prevent sudden infant death syndrome (SIDS) but may not directly help with breathing in the context of bronchiolitis (Choice D).

Correct Answer: C

Rationale: The correct answer is C because providing a developmentally safe environment for a 6-month-old infant is crucial as they begin to explore their surroundings more actively. This includes ensuring that the environment is free of hazards and that the infant is supervised to prevent accidents. Choice A is incorrect because self-feeding finger foods may not be developmentally appropriate for a 6-month-old infant. Choice B is incorrect as most infants are able to sit up with support around 6 months of age without the need for specific teaching strategies. Choice D is also incorrect as while appetite changes can occur, explaining a specific increase in appetite over the next 6 months is not a primary focus when discussing developmental changes with parents of a 6-month-old.

Correct Answer: D

Rationale: The priority action for the nurse is to review the immunization documentation of the child with HIV. This step ensures that the child has received the necessary vaccines to protect against pertussis and other preventable diseases. It is essential to verify the immunization status to provide appropriate care and prevent further transmission of infectious diseases within the foster home. Removing the child from the foster home (Choice A) may not be necessary if the child is adequately protected through immunization. Reporting the exposure to the health department (Choice B) is important but not the first action. Placing the child in reverse isolation (Choice C) is not indicated for pertussis exposure.

Correct Answer: A

Rationale: Frequent swallowing post-tonsillectomy may indicate bleeding. Inspecting the posterior oropharynx is essential to assess for any signs of bleeding, such as fresh blood or clots, which may necessitate immediate intervention. Option B is incorrect as teeth clenching or grinding is not directly related to the observation of frequent swallowing in this scenario. Option C is incorrect because stimulating the gag reflex is not necessary at this point and may be uncomfortable for the child. Option D is incorrect as evaluating a change in voice tone is not relevant to the situation of observing frequent swallowing.

Correct Answer: B

Rationale: Teaching children how to swim is valuable, but parental supervision around water is essential to prevent drowning. It's crucial to emphasize constant supervision when young children are near water, regardless of their swimming abilities. The other choices (A, C, and D) demonstrate appropriate safety measures for injury prevention in toddlers, such as securing cleaning supplies, ensuring helmet use during tricycle rides, and using a car seat for every car ride.
