The psychomotor domain includes physical movement, coordination, and use of the motor- skill areas. Development of these skills requires practice and is measured in terms of speed, precision, distance, procedures, or techniques in execution. Thus, when a patient is able to perform a return demonstration, such as changing their surgical dressing, it is the psychomotor domain that has been demonstrated.
Correct Answer is D
Explanation
Choice A rationale
Subjective documentation cannot be quantified. It is based on the patient’s personal experiences and perceptions, which can vary greatly among individuals.
Choice B rationale
A patient’s description is an example of subjective data, not objective data. Subjective data is information that comes directly from the patient and includes their feelings, perceptions, and reported symptoms.
Choice C rationale
Subjective data can incorporate a patient’s emotions. Emotions can provide valuable insights into a patient’s mental and emotional health, which is an important aspect of overall health.
Choice D rationale
A 2-centimeter red wound with exudate is an example of objective data. Objective data is measurable, observable, and can be verified by more than one person.
