Drew, Steven, Jen, and Lina are all college friends who are shopping at the local discount store. As they walk through the pharm
acy department they notice the free automated blood pressure machine. For fun they all decide to take their blood pressure to see what their readings are. Drew's reading was 122/88 mm Hg, Steven's reading was 132/92 mm Hg, Jen's reading was 110/70 mm Hg, and Lina's reading was 100/60 mm Hg. While in the pharmacy section they also look through the vast array of supplements available. Jen has a family history of osteoporosis and is of Asian descent. She has a small bone frame and is also lactose intolerant. She looks at the calcium supplements but isn't sure what to buy. In the past Lina has been diagnosed as having iron-deficiency anemia and is currently not taking any dietary supplements. She shops in the iron supplement section but is also confused on what to buy. Drew and Steven decide to purchase a large bottle of multi-vitamin/multi-mineral supplements to share. Neither Drew nor Steven consistently consumes vegetables or fruits, and they think that taking a supplement would be good for their health. Refer to Case Study 23-1. Which of the four friends has a blood pressure reading that would be considered pre-hypertension?

It will make the heart beat faster to get the blood oxygenated.
