Which among the following can affect/influence vital signs?

Vital signs, which include temperature, pulse, respiration rate, and blood pressure, can be influenced by a variety of factors. Stress is known to elevate heart rate and blood pressure due to the body's response to anxiety or pressure, as it triggers the release of stress hormones. Age is another critical factor, as vital signs can vary significantly through different life stages; for example, infants typically have higher heart rates than older children and adults. Lastly, sex can also play a role, as physiological differences between males and females can lead to variations in baseline vital signs, including heart rate and blood pressure.

Given that stress, age, and sex all individually impact vital signs, the correct answer encompasses all of these factors, affirming that they collectively contribute to variations observed in vital signs. Understanding these influences is essential for caregivers to accurately assess and respond to the health and well-being of individuals under their care.
