A nurse is teaching a newly licensed nurse about heart sounds. Which of the following sounds is heard when the aortic and pulmonic valves close?

Choice A reason: Change in marital status is a psychological stressor, activating the hypothalamic-pituitary-adrenal axis, increasing cortisol, and causing emotional distress. It affects mental health through social and emotional pathways but does not directly disrupt physiological homeostasis, unlike physical injuries that trigger systemic stress responses.

Choice B reason: A burn injury is a physiological stressor, causing tissue damage, pain, and systemic inflammation. It activates the sympathetic nervous system and releases stress hormones (e.g., catecholamines, cortisol), increasing metabolic demand, heart rate, and immune response to repair tissue and combat potential infections, disrupting bodily homeostasis.

Choice C reason: Academic pressure is a psychological stressor, engaging cognitive and emotional pathways, elevating cortisol via the hypothalamic-pituitary-adrenal axis. It impacts mental health but lacks direct physical disruption to bodily systems, unlike physiological stressors that cause immediate tissue or metabolic changes, such as infections or injuries.

Choice D reason: Financial difficulties are psychological stressors, triggering anxiety and cortisol release through emotional distress. They affect mental health but do not directly cause physiological disruption like tissue damage or metabolic imbalance, which are characteristic of physiological stressors impacting the body’s physical homeostasis and organ function.

Choice A reason: Applying socks without non-slip soles during ambulation increases fall risk due to reduced traction on smooth surfaces. Non-slip footwear or hospital-grade socks with grips are preferred to ensure stability. Socks alone do not provide sufficient grip, potentially leading to slips, especially in elderly or mobility-impaired clients, making this an unsafe fall prevention strategy.

Choice B reason: Locking the wheels on a client’s bed prevents unintended movement during transfers or repositioning, reducing fall risk. Stable beds ensure a secure base for clients with impaired mobility or balance, minimizing accidents. This is a standard safety measure in healthcare settings to enhance client safety during bed-related activities, such as getting in or out of bed.

Choice C reason: Placing brakes on wheelchairs ensures stability during transfers, preventing the chair from moving unexpectedly. This is critical for clients with limited mobility or strength, as an unlocked wheelchair can shift, leading to falls. Applying brakes is a fundamental safety practice in fall prevention protocols, ensuring a secure environment for safe client transfers.

Choice D reason: Keeping the bed in a high position increases fall risk, as it elevates the distance to the floor, making falls more dangerous, especially for confused or mobility-impaired clients. Beds should be kept in the lowest position when unattended to minimize injury risk, making this an incorrect strategy for fall prevention in healthcare settings.

Choice E reason: Providing under-bed lighting at night improves visibility, reducing fall risk by helping clients see obstacles or orient themselves in low-light conditions. Adequate lighting mitigates disorientation, particularly for elderly clients or those with visual impairments, supporting safe ambulation and transfers, making it an effective component of fall prevention strategies.
