A nurse is teaching a class about nonpharmacological therapies to decrease stress. The nurse should include which of the following therapies?

(Select All that Apply)

A) Viral infection:
Chronic stress can suppress the immune system, making individuals more susceptible to infections, including viral infections. Prolonged stress can dysregulate the immune response, leading to increased vulnerability to various illnesses.

B) Increased cognitive awareness:
Chronic stress often impairs cognitive function rather than enhancing it. It can lead to difficulties with concentration, memory problems, and cognitive fatigue due to the continuous activation of the body's stress response system.

C) Hypotension:
Chronic stress typically leads to increased blood pressure rather than hypotension. Stress activates the sympathetic nervous system, resulting in the release of stress hormones like cortisol and adrenaline, which can elevate blood pressure over time.

D) Increased energy:
While acute stress can trigger a temporary surge in energy due to the release of stress hormones, chronic stress often leads to fatigue and exhaustion. Prolonged activation of the stress response system can deplete energy reserves and disrupt sleep patterns, resulting in feelings of fatigue and lethargy.

A. Increased blood pressure:
In hypovolemia, the body experiences a significant loss of blood volume, which leads to a reduction in the amount of blood available to circulate through the vessels. This causes a drop in blood pressure, known as hypotension, rather than an increase. The body tries to compensate for the lower blood volume by constricting blood vessels and increasing heart rate, but this typically isn't sufficient to increase blood pressure to normal levels.

B. Decreased heart rate:
The body's natural response to hypovolemia includes an increase in heart rate, known as tachycardia, as the heart attempts to pump the remaining blood more efficiently to vital organs. This compensatory mechanism aims to maintain cardiac output despite the decreased blood volume.

C. Dyspnea:
Dyspnea, or difficulty breathing, can occur in many medical conditions, including heart failure and respiratory issues. While it can be seen in severe cases of hypovolemia, particularly if the condition leads to shock and subsequent multi-organ failure, it is not a primary or specific sign of hypovolemia.

D. Weak pulse:
A weak pulse is a primary and direct manifestation of hypovolemia. Due to the reduced volume of circulating blood, the heart has less blood to pump with each contraction, leading to a weaker pulse. This symptom indicates a decreased perfusion pressure, which is characteristic of hypovolemia. The body's compensatory mechanisms include vasoconstriction and an increased heart rate, but these measures often result in a pulse that is rapid but weak.
