Which is the best method to begin teaching the adult patient how to self-administer tube feeding through a new gastrostomy tube?

A. Cognitive learning involves knowledge acquisition, understanding, and mental skills such as remembering and problem-solving. It does not involve physical skill demonstration.
B. Perceptive is not one of the commonly defined domains of learning used in nursing education.
C. Psychomotor learning involves the development of physical or manual skills. Demonstrating the correct technique for self-injection is a clear example of a psychomotor skill.
D. Affective learning focuses on emotions, attitudes, values, and feelings. It would apply more to how a patient feels about self-injecting rather than the physical act itself.

A. Constriction of the pupils is the correct response. When testing for accommodation, the pupils constrict as the patient focuses on a near object, demonstrating normal accommodation.
B. Disconjugate movement of the eyes (where the eyes do not move together) is an abnormal finding. The eyes should move symmetrically and conjugately (together).
C. Consensual light reflex refers to the pupillary response to light in one eye causing a constriction in both eyes, but this is not part of the accommodation test.
D. Dilation of the pupils is the opposite of what should occur during accommodation. The pupils should constrict when focusing on a near object.
