A nurse is admitting a client who has pertussis. Which of the following types of transmission-based precautions should the nurse initiate?

A) Hydrochlorothiazide: Hydrochlorothiazide is a thiazide diuretic that promotes sodium and water excretion, leading to decreased blood volume and decreased potassium excretion. While it can cause hypokalemia due to increased potassium excretion, it does not typically lead to hyperkalemia.

B) Spironolactone: Spironolactone is a potassium-sparing diuretic that inhibits aldosterone, leading to decreased sodium reabsorption and increased potassium retention. This mechanism of action can predispose clients to hyperkalemia due to potassium retention. Additionally, spironolactone can cause hyponatremia by promoting the excretion of sodium and water. Therefore, clients receiving spironolactone are at risk for both hyperkalemia and hyponatremia.

C) Furosemide: Furosemide is a loop diuretic that inhibits sodium and chloride reabsorption in the loop of Henle, promoting sodium, chloride, potassium, and water excretion. While it can cause hypokalemia due to increased potassium excretion, it does not typically lead to hyperkalemia.

D) Metolazone: Metolazone is a thiazide-like diuretic that acts similarly to hydrochlorothiazide by promoting sodium and water excretion. Like hydrochlorothiazide, it can cause hypokalemia due to increased potassium excretion but does not typically lead to hyperkalemia.

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.
