Answer to Question 1
B
Hypotension is a systolic blood pressure (SBP) less than 90 mm Hg or a diastolic blood pressure (DBP) less than 60 mm Hg. The most common alteration in blood pressure is hypertension, an often asymptomatic disorder characterized by persistently elevated blood pressure. Hypertension is defined as SBP greater than 140 mm Hg, DBP greater than 90 mm Hg. Orthostatic hypotension, also referred to as postural hypotension, is a reduction of SBP of at least 20 mm Hg or reduction of DBP of at least 10 mm Hg within 3 minutes of quiet standing. It occurs when patients with normal blood pressure experience a drop in blood pressure upon rising to an upright position and is associated with symptoms of lightheadedness or dizziness.
Answer to Question 2
D
Ethics of care suggest that health care workers resolve ethical dilemmas by paying attention to relationships and stories of the participants and by promoting a fundamental act of caring. Attention to relationships distinguishes the ethics of care from other ethical viewpoints because it does not necessarily apply universal principles that are intellectual or analytical. Deontology defines actions as right or wrong based on right-making characteristics such as truth and justice. You use utilitarian ethics when determining the value of something based primarily on its usefulness and effects or consequences. Feminist ethics proposes that we routinely ask how ethical decisions will affect women as a way to repair a history of inequality.
