Which of the following sets of vital signs represents normal values for a healthy adult at rest?

Rationale: A. Blood pressure of 130/85 mmHg is slightly above normal, and a respiratory rate of 22 breaths/min is at the upper limit of normal, which may indicate mild tachypnea. Temperature of 100°F is slightly elevated. These values are not considered fully normal for a healthy adult at rest. B. Heart rate of 55 bpm is slightly below normal, and respiratory rate of 10 breaths/min is at the lower limit, which may be bradycardic or hypoventilating depending on the context. Temperature of 97°F is slightly below average. While some healthy adults may have these values, they are borderline and not considered standard normal ranges. C. Blood pressure 120/80 mmHg, heart rate 72 bpm, respiratory rate 16 breaths/min, and temperature 98.6°F all fall within the accepted normal range for a healthy adult at rest. This set accurately represents normal adult vital signs. D. Blood pressure 140/90 mmHg is considered elevated (stage 2 hypertension), and heart rate 100 bpm is at the upper limit of normal. Temperature 99.5°F is slightly elevated. Overall, these values indicate borderline or mildly abnormal vital signs rather than fully normal values.
