Final answer:
The recommended blood pressure reading for a patient with chronic kidney disease and hypertension is below 130/80 mm Hg.
Step-by-step explanation:
The new guidelines from the American College of Cardiology and American Heart Association recommend that blood pressure (BP) readings for a patient with chronic kidney disease and hypertension should be below 130/80 mm Hg to be within a healthy range. This indicates that option c, below 130/80 mm Hg, is the correct answer. Systolic pressure represents the pressure on the blood vessels when the heart beats, and diastolic pressure represents the pressure when the heart is resting between beats.
