Which of the following is NOT a characteristic of a pulse?

Correct Answer: D

Rationale: Pulse characteristics include rate (speed), rhythm (regularity), and volume (strength), per clinical assessment standards. Humidity (D) relates to environment or skin, not pulse. Rate (A) counts beats per minute, rhythm (B) assesses pattern, and volume (C) gauges force all measurable via palpation. Humidity's irrelevance to pulse properties, which focus on arterial pulsation, makes D the correct answer as the non-characteristic, aligning with physiological definitions.

Correct Answer: A

Rationale: Negligence is failure to act as a reasonable person would (A), per legal definition e.g., missing care standards. It's unintentional (B), causes harm (C), not all (D). A captures negligence's essence, making it true.
