Which directional term means more toward the head or above another structure?

Choice A rationale:

The anterior surface of the drape is not the correct choice because it includes the central sterile area, which should never be touched by the nurse. Touching the central sterile area contaminates the field.

Choice B rationale:

The outer 1-inch border of the drape is the correct choice for the nurse to touch. This border is considered non-sterile and can be handled without contaminating the sterile field. It acts as a barrier, preventing contaminants from reaching the central sterile area.

Choice C rationale:

The top inner corners of the drape are part of the central sterile area and should not be touched by the nurse. Touching this area would contaminate the sterile field.

Choice D rationale:

The posterior aspect of the drape is not the correct choice because it is part of the central sterile area. Touching this area would contaminate the sterile field. When preparing a sterile field, it is essential for the nurse to follow strict aseptic techniques to maintain the sterility of the field. This includes touching only the designated non-sterile areas, such as the outer 1-inch border of the sterile drape, to avoid contamination.

Choice A rationale:

Pulse pressure is the difference between systolic and diastolic blood pressure and is not related to changing positions or the symptoms described in the scenario.

Choice B rationale:

Essential hypertension is a chronic medical condition characterized by elevated blood pressure levels persistently exceeding 140/90 mmHg. It is not directly related to positional changes or postural hypotension symptoms.

Choice C rationale:

Postural (orthostatic) hypotension occurs when a person experiences a sudden drop in blood pressure upon standing up from a sitting or lying position. This drop in blood pressure can lead to symptoms such as dizziness, lightheadedness, and fainting. Slowly changing positions is essential in managing postural hypotension because abrupt movements can worsen these symptoms. Educating the client about the importance of gradual position changes is crucial in preventing or minimizing postural hypotension-related symptoms.

Choice D rationale:

Pre-hypertension refers to blood pressure levels that are higher than normal but not high enough to be diagnosed as hypertension. It does not directly relate to the symptoms described in the scenario.
