A community health nurse is performing a home visit for a client and is evaluating the home environment for safety. Which of the following findings would indicate to the nurse that the client has a proper understanding of safety in the home?

A single light fixture hangs along the sidewalk to the house.

The batteries in the smoke alarms are changed annually.

A small area rug is placed at the front door.

Electrical cords are secured under furniture.

Answer and Explanation

The Correct Answer is B

Choice A reason: A single light fixture along the sidewalk provides limited illumination, insufficient for comprehensive safety. Multiple, evenly spaced lights are needed to prevent falls, especially for older adults. Inadequate lighting increases risks of trips or assaults, indicating the client’s understanding of outdoor safety is incomplete and does not fully address home safety needs.
Choice B reason: Changing smoke alarm batteries annually ensures functional alarms, reducing fire-related mortality by 50%. Regular maintenance supports early smoke detection, enabling timely evacuation or response. This action reflects a strong understanding of fire safety, a critical home safety component, making it the best indicator of the client’s safety awareness.
Choice C reason: A small area rug at the front door poses a tripping hazard, particularly for those with mobility issues. Loose rugs can lead to falls, causing injuries like fractures. This finding suggests the client does not fully understand fall prevention, a key aspect of home safety, making it an incorrect indicator of safety awareness.
Choice D reason: Securing electrical cords under furniture risks fire hazards if cords are damaged or pinched, potentially causing electrical shorts. Cords should be secured along walls or with covers to prevent tripping without compromising safety. This indicates a misunderstanding of electrical safety, increasing fire or injury risks, and is not a correct safety measure.

Correct Answer is C

Explanation

Choice A reason: Dehydration is not directly associated with gastroesophageal reflux, which involves gastric acid backflow. Dehydration affects fluid balance, not reflux mechanisms, so this statement is inaccurate and irrelevant to preterm contractions, making it incorrect.
Choice B reason: Dehydration is not caused by decreased hemoglobin and hematocrit; rather, it may elevate these due to hemoconcentration. This statement reverses the relationship, making it factually incorrect and unrelated to preterm labor risks.
Choice C reason: Dehydration can increase preterm labor risk by reducing uterine blood flow and triggering contractions via oxytocin release. This evidence-based link supports hydration as a preventive measure, making it the correct statement for teaching in this scenario.
Choice D reason: Dehydration is treated with fluid replacement, not calcium supplements, which address bone health or specific deficiencies. This treatment is irrelevant to dehydration or preterm labor, making it an incorrect and inappropriate recommendation.

A. Your child can return to school 24 hours after beginning antibiotics. B. Your child can return to school after a negative titer result. C. Your child can return to school once the fever has subsided. D. Your child can return to school once the lesions have crusted over.

Correct Answer is D

Explanation

Choice A reason: Varicella, a viral infection, is not treated with antibiotics, which target bacteria. Returning to school after 24 hours of antibiotics is incorrect, as contagiousness persists until lesions crust, typically 5-7 days, risking transmission if the child returns prematurely.
Choice B reason: A negative titer result indicates immunity or resolved infection but is not a practical criterion for school return. Varicella contagiousness depends on lesion crusting, not serology, which is complex and unnecessary when clinical signs confirm reduced infectivity in affected children.
Choice C reason: Fever subsidence does not ensure non-contagiousness in Varicella. The virus spreads via respiratory droplets and lesions until crusted. Allowing return based on fever ignores transmission risk, as active lesions remain infectious, potentially spreading the virus in school settings.
Choice D reason: Varicella is contagious until lesions crust over, typically 5-7 days post-rash. Crusting indicates the end of viral shedding, ensuring safety for school return. This aligns with infection control guidelines, preventing transmission via contact or respiratory routes in communal settings.
