Blood pressure is commonly measured with a cuff placed around the arm, with the cuff pressure (which is a measure of the arterial blood pressure) indicated with a mercury manometer (see Video 2.2). A typical value for the maximum value of blood pressure (systolic pressure) is 120 mmHg. Why wouldn't it be simpler and less expensive to use water in the manometer rather than mercury? Explain and support your answer with the necessary calculations.

In situations where dissolved oxygen is present at a concentration below the concentration that would be in equilibrium with the atmosphere, net O2 gasliquid transfer will take place across the air:water interface. The "driving force" for this process is the "oxygen deficit" (D), or the difference between equilibrium (saturation) dissolved oxygen concentration and actual dissolved oxygen concentration:= Cs-C (5)D = oxygen deficit (mg/L)Cs = saturation (equilibrium) dissolved oxygen concentration (mg/L).When aeration is the only process that affects dissolved oxygen concentration, the deficit is generally assumed to change according to the following expression:dD/dt = K (6)where, Ka = overall, volumetric aeration rate constant (hr-1). Ka is referred to as an overall mass-transfer coefficient, based on liquid-phase measurements. Using this information, develop expressions to describe D and C as functions of time. For these expressions, you should define D0 and C0 as the initial values of D and C, respectively.

How would the nurse document a drop in blood pressure when a client moves rapidly from a lying to a standing position?Orthostatic hypotension-Orthostatic hypotension specifically refers to an abnormally low blood pressure that occurs when an individual assumes a standing position. Orthostatic hypotension is also known as postural hypotension. It may be a result of internal bleeding, fluid depletion, or loss of neurovascular control preventing vasoconstriction from regulating blood pressure. Malignant hypotension and orthostatic dehydration are inaccurate terms that are not used. Vasomotor instability occurs during menopause and results in hot flashes and night sweats.
