A community health nurse is providing an educational session on childhood poisoning at a local school. What should the nurse advise as the first action if poisoning occurs?

Correct Answer: A

Rationale: In the event of poisoning, the recommended first action is to call the poison control center. Poison control specialists can provide immediate guidance on how to manage the situation effectively. Bringing the child to the emergency department (Choice B) may be necessary depending on the severity of the poisoning, but contacting poison control first is crucial for appropriate and timely intervention. Inducing vomiting (Choice C) is not advised in all cases of poisoning and should only be done under the guidance of healthcare professionals. Calling an ambulance (Choice D) may be necessary in some severe cases, but the initial step should be to contact poison control for expert advice.

Correct Answer: B

Rationale: The correct method of safely using a sterile dressing is to discard it after 24 hours of use. This is important to prevent contamination and promote proper wound healing. Choice A is incorrect because reusing a dressing, even if it appears clean, can introduce contaminants. Choice C is incorrect as dressing changes should not be based solely on visible drainage; they should be done within the recommended time frame. Choice D is incorrect because changing a dressing every 4 hours, regardless of its condition, can lead to unnecessary wastage and disturbance to the wound healing process.

Correct Answer: B

Rationale: The presence of chronic illness is the factor that places a patient at the highest risk for infection. Chronic illness can compromise the immune system's ability to fight off infections effectively, making individuals more susceptible to getting sick. Option A, a healthy immune system, actually reduces the risk of infection. Option C, being well-nourished, can support overall health but does not directly correlate with infection risk. While age over 65 years is a risk factor for certain infections due to age-related immune system changes, chronic illness has a more significant impact on infection risk.

Correct Answer: D

Rationale: The correct answer is D: Clean hands thoroughly before and after patient contact. Hand hygiene is crucial for maintaining medical asepsis in a healthcare setting as it helps prevent the spread of infections between patients and healthcare workers. Choice A is incorrect because instruments should be sterilized regularly, not just when visibly contaminated. Choice B is incorrect as sterile gloves are not required for all patient interactions, only for specific procedures. Choice C is incorrect because patient areas should be disinfected regularly throughout the day, not just at the end of the day.

Correct Answer: B

Rationale: The correct action to promote healing in a patient with impaired skin integrity is to use sterile saline to clean the wound. Sterile saline helps prevent infection and promotes healing of wounds by keeping the area clean. Applying a dry, sterile dressing (Choice A) may not be effective as it does not address the need for wound cleaning. Applying a warm compress (Choice C) may not be suitable for all types of wounds and could potentially cause harm. Keeping the wound open to air (Choice D) is generally not recommended as it can lead to infection and slow down the healing process.
