A nurse is discussing informatics with a newly licensed nurse.
The nurse identifies that informatics is defined as the use of information and technology for which of the following?

Choice A rationale

Client administered nitroglycerin is objective data because it is a documented action performed by the client and can be verified. Subjective data, on the other hand, comes from the client's perspective.

Choice B rationale

Client reports chest pain after mowing the lawn this morning is subjective data because it is a statement made by the client about their experience. It describes their feelings and circumstances as they perceive them.

Choice C rationale

Client's blood pressure is 182/98 mmHg is objective data because it is a measurable physiological parameter obtained through assessment. It is a factual finding that can be directly observed and recorded.

Choice D rationale

Client's skin is pale and diaphoretic is objective data because these are observable physical signs noted by the nurse during assessment. They are factual descriptions of the client's physical condition.

Choice A rationale

Providing additional written instructions is a helpful teaching strategy but does not directly demonstrate the patient's ability to self-administer the injection correctly. It addresses the teaching method, not the outcome of the teaching.

Choice B rationale

The patient denying concerns does not necessarily indicate successful learning. The patient might have unexpressed concerns or may not fully understand the procedure despite verbalizing otherwise. This statement reflects the patient's verbalization, not their demonstrated skill.

Choice C rationale

The patient correctly self-administering their next scheduled dose of insulin is the most direct and reliable evidence that the teaching was successful. It demonstrates that the patient has acquired the necessary knowledge and skills to perform the injection safely and accurately in a real-life situation.

Choice D rationale

Identifying the steps and equipment used indicates that the patient has some understanding of the procedure. However, it does not guarantee that they can perform the injection correctly. Practical demonstration is required to confirm successful learning of a psychomotor skill.
