A nurse is evaluating a patient’s sensory function.
Which of the following sensory stimuli is primarily associated with the tactile system?
Detecting the scent of a rose
Observing the color of a flower
Feeling the texture of a fabric
Hearing the sound of a bell
The Correct Answer is C
Choice A rationale
Detecting the scent of a rose is primarily associated with the olfactory system, not the tactile system.
Choice B rationale
Observing the color of a flower is primarily associated with the visual system, not the tactile system.
Choice C rationale
Feeling the texture of a fabric is primarily associated with the tactile system. The tactile system, part of the somatosensory system, allows us to perceive touch, pressure, temperature, pain, and vibration.

Correct Answer is B
Explanation
Choice A rationale
Chilling the irrigant prior to the procedure is not recommended. Cold irrigant can cause discomfort and potentially lead to vasoconstriction, which can impede the healing process.
Choice B rationale
Irrigating the wound until the solution that is draining is clean is a standard practice in wound care. This helps to ensure that all debris and potential contaminants are removed from the wound.
Choice C rationale
Holding the tip of the syringe at least 13 cm (0.5 in) above the wound while irrigating is not a standard practice. The syringe should be held close to the wound to ensure effective irrigation.
Choice D rationale
Flushing the wound from the most contaminated area to the cleanest area is not a standard practice. The wound should be irrigated from the cleanest to the dirtiest area to prevent the spread of contamination.
