A nurse is educating a client who is experiencing sleep disturbances and desires to decrease caffeine intake. Which of the following beverages should the nurse recommend?

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) Allow the client to rest for 10 to 15 seconds after each suctioning attempt: Allowing the client to rest between suctioning attempts helps to minimize hypoxemia and reduces the risk of trauma to the airway mucosa. It also allows the client to recover from the physiological stress of suctioning before initiating another attempt.

C) Apply suction for less than 10 seconds: Prolonged suctioning can lead to hypoxemia and tissue trauma. The nurse should limit suctioning to less than 10 seconds per pass to minimize these risks and prevent complications such as mucosal damage and bleeding.

B) Set the suction pressure to 110 mm Hg: The appropriate suction pressure for endotracheal suctioning depends on various factors, including the client's age, condition, and clinical status. While suction pressures of 80 to 120 mm Hg are commonly used for adults, the specific pressure setting should be individualized based on the client's needs and should not exceed the safe range to prevent mucosal injury or hypoxemia.

D) Apply suction when inserting the catheter: Suction should be applied only during withdrawal of the catheter to minimize the risk of mucosal trauma and hypoxemia. Applying suction during catheter insertion can increase the risk of airway trauma and should be avoided.
