The nurse prepares to assess a client's temperature.
Which should the nurse keep in mind that can falsely lower the body temperature? (Select all that apply.)
Drinking something cold.
Exercising.
An outdoor temperature of 99°F.
A cold climate.
Physical inactivity.
Correct Answer : A,B,E
Choice A rationale:
Drinking something cold can lower the oral temperature temporarily. When a person consumes something cold, the blood vessels in the mouth can constrict, leading to a lower temperature reading. However, it's important to note that this effect is temporary.
Choice B rationale:
Exercising can increase blood circulation and raise body temperature. However, immediately after intense physical activity, the body might start sweating, leading to a temporary drop in temperature. Prolonged or moderate exercise, on the other hand, generally increases body temperature.
Choice C rationale:
An outdoor temperature of 99°F does not directly affect body temperature. Body temperature is regulated internally and does not fluctuate based on external temperatures unless the person is exposed to extreme conditions for a prolonged period.
Choice D rationale:
A cold climate might lower skin temperature, but it does not necessarily reduce the body's core temperature significantly. The body has mechanisms to conserve heat in colder environments.
Choice E rationale:
Physical inactivity can lower body temperature, especially in situations where the person is sedentary for an extended period. Reduced physical activity can slow down metabolic processes, leading to a lower body temperature.

Correct Answer is B
Explanation
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.
Correct Answer is A
Explanation
Choice A rationale:
Superior means more toward the head or above another structure. In anatomical terms, superior refers to a structure being closer to the head or higher than another structure in the body. For example, the head is superior to the neck because it is above the neck.
Choice B rationale:
Medial refers to the middle or near the middle of the body. It is used to describe structures that are closer to the midline of the body. For example, the nose is medial to the eyes because it is closer to the midline of the face.
Choice C rationale:
Ventral refers to the front or belly side of the body. It is opposite to dorsal, which refers to the back side of the body. Ventral structures are those that are located on the front side of the body, like the chest and abdomen.
Choice D rationale:
Caudal means toward the tail or inferior end of the body. It is opposite to superior and refers to structures that are located below or toward the tail end of the body. For example, the feet are caudal to the head because they are below the head.
