Objective data are measurable and observable by the nurse. A recorded
temperature is objective, while pain, nausea, and dizziness are subjective
symptoms reported by the patient.
Question 2
Which vital sign is considered normal for a healthy adult?
A. Heart rate of 40 beats/min
B. Respiratory rate of 16 breaths/min
C. Blood pressure of 180/100 mmHg

Rationale:
A normal adult respiratory rate is 12–20 breaths per minute. The other values are
outside normal limits.
