Which of the following are effects of shock?

The correct choice highlights a primary concern in cases of shock: the reduced delivery of oxygen to body tissues and organs. When someone is in shock, their circulatory system is unable to effectively pump blood, which results in inadequate oxygen supply. This can lead to cellular dysfunction and, if untreated, may result in organ failure or even death.

Shock can be caused by various factors, including trauma, severe dehydration, or allergic reactions, and its effects often manifest in a range of symptoms such as weakness, confusion, and rapid breathing. Understanding that shock compromises oxygen delivery is critical for prompt recognition and intervention.

The other options do not accurately describe the physiological changes that occur during shock. While the body may initially respond to shock with increased heart rate in an attempt to maintain blood flow, the correct effects involve a decline in perfusion to critical areas, rather than increasing blood flow to the extremities or presenting with high blood pressure or fever.
