What organ is contained in the cranial cavity?

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.

Choice D rationale:

When preparing to open a sterile pack, the nurse must touch only the inner surface of the inner wrapper to maintain sterility. This is a fundamental principle of aseptic technique. Sterile items should be handled with care to prevent contamination. By touching only the inner surface of the inner wrapper, the nurse ensures that the contents of the pack remain sterile and safe for use in medical procedures. Any contact with the outer surface or other non-sterile items can compromise the sterility of the contents.

Choice A rationale:

Placing the sterile pack on a clean surface is a good practice but does not ensure the maintenance of sterility. Sterile items should be placed on a sterile surface or field to prevent contamination. Placing the pack on a clean surface may still expose it to potential contaminants, compromising its sterility.

Choice B rationale:

Turning the pack so that the first flap faces the nurse's body is incorrect. The first flap should be opened away from the nurse to avoid the risk of contamination. By opening the flap away from the nurse, any potential contaminants in the air are less likely to come into contact with the sterile contents.

Choice C rationale:

Opening the right-side flap first is not a standard practice for opening a sterile pack. The choice of which side to open first may vary based on individual preference or the design of the packaging. The key factor is to maintain the sterility of the contents by handling the pack appropriately, as mentioned in choice D.
