Which of the following statements is true?

Which of the following statements is true?

• A. Tachycardia is defined as a heart rate less than 60 bpm.
• B. Bradycardia is defined as a heart rate greater than 100 bpm.
• C. Hypertension is defined as a systolic BP greater than 140 mmHg or diastolic BP greater than 90 mmHg.
• D. Hypoglycemia is defined by high blood glucose.

Answer: (C)

Blood pressure thresholds classify hypertension. Hypertension is defined as a systolic BP greater than 140 mmHg or a diastolic BP greater than 90 mmHg. This makes the statement true. Tachycardia is a heart rate that’s too fast (typically over 100 bpm), bradycardia is a heart rate that’s too slow (typically under 60 bpm), and hypoglycemia is low blood glucose, not high.
