A nurse at the clinic is involved in disease surveillance. What level of prevention is this?

Choice A rationale
Fatigue is a subjective symptom reported by the client. It is based on the client’s personal experience and cannot be objectively measured or observed by the nurse. Therefore, it is not considered objective data.
Choice B rationale
Dizziness is also a subjective symptom reported by the client. It reflects the client’s personal experience and cannot be directly observed or measured by the nurse. As such, it is not considered objective data.
Choice C rationale
Numbness is another subjective symptom reported by the client. It is based on the client’s personal sensation and cannot be objectively measured or observed by the nurse. Therefore, it is not considered objective data.
Choice D rationale
Physical examination results are objective data. They are obtained through direct observation, measurement, and assessment by the nurse. Examples of objective data include vital signs, physical examination findings, and laboratory results. These data are reproducible and can be verified by other healthcare professionals.

Choice A rationale
Following the order as prescribed without clarification can lead to errors if the order is unclear or incomplete.
Choice B rationale
Administering the medication at a later time without clarification can also lead to errors and may delay necessary treatment.
Choice C rationale
Disregarding the order and seeking approval from another physician is not appropriate. The nurse should seek clarification from the ordering physician.
Choice D rationale
Asking the physician to clarify the dosage and route ensures that the order is accurate and complete, reducing the risk of medication errors.
