Based on the provided readings and classifications, determine the correct category for high blood pressure, the function of the constriction in a clinical thermometer, and the classification for a BMI

C. Tekanan darah tinggi peringkat 2 The blood pressure reading is SYS (Systolic) = 142 mmHg and DIA (Diastolic) = 91 mmHg. According to standard classifications:

• Normal: SYS < 120 and DIA < 80
• Hypertension Stage 1: SYS 130-139 or DIA 80-89
• Hypertension Stage 2: SYS $\ge$ 140 or DIA $\ge$ 90 Since the systolic pressure is 142 mmHg (which is $\ge$ 140) and the diastolic pressure is 91 mmHg (which is $\ge$ 90), this reading falls into the category of Hypertension Stage 2.

C. Pencerutan Y points to the constriction (kink) in the clinical thermometer, located just above the bulb. This constriction prevents the mercury from falling back into the bulb immediately after the thermometer is removed from the patient, allowing time for an accurate reading.

D. Berlebihan jisim badan The student's Body Mass Index (BMI) is 26.58 kgm$^{-2}$. According to standard BMI classifications:

• Underweight: < 18.5 kgm$^{-2}$
• Normal weight: 18.5 - 24.9 kgm$^{-2}$
• Overweight: 25.0 - 29.9 kgm$^{-2}$
• Obese: $\ge$ 30.0 kgm$^{-2}$ Since 26.58 kgm$^{-2}$ falls between 25.0 and 29.9 kgm$^{-2}$, the student is classified as overweight.
