Which may cause hyperkalemia?
Renal failure
Diarrhea
Blood transfusion
Diaphoresis
The Correct Answer is A
Choice A reason: Renal failure can cause hyperkalemia because the kidneys are unable to excrete excess potassium from the body. This can lead to high levels of potassium in the blood, which can affect the heart and muscles.
Choice B reason: Diarrhea can cause hypokalemia, not hyperkalemia, because it can lead to loss of potassium from the gastrointestinal tract. This can result in low levels of potassium in the blood, which can also affect the heart and muscles.
Choice C reason: Blood transfusion can cause hyperkalemia if the blood is old or hemolyzed, meaning that the red blood cells have broken down and released potassium into the plasma. This can increase the potassium levels in the recipient's blood.
Choice D reason: Diaphoresis, or sweating, can cause hypokalemia, not hyperkalemia, because it can lead to loss of potassium from the skin. This can also lower the potassium levels in the blood.

Correct Answer is B
Explanation
Choice A reason: This is incorrect because bradypnea is a term for slow breathing, usually less than 12 breaths per minute. The client is breathing rapidly, not slowly.
Choice B reason: This is correct because Kussmaul's respirations are a type of breathing pattern that is deep, regular, and rapid, usually more than 20 breaths per minute. Kussmaul's respirations are a sign of metabolic acidosis, which occurs in diabetic ketoacidosis due to the accumulation of ketones in the blood. The client is trying to exhale the excess carbon dioxide and lower the acidity of the blood.
Choice C reason: This is incorrect because Cheyne-Stokes respirations are a type of breathing pattern that is irregular, with periods of apnea (no breathing) alternating with periods of rapid breathing. Cheyne-Stokes respirations are a sign of cerebral dysfunction, such as stroke, brain injury, or coma.
Choice D reason: This is incorrect because Biot's respirations are a type of breathing pattern that is irregular, with periods of apnea (no breathing) interspersed with periods of normal breathing. Biot's respirations are a sign of brainstem damage, such as meningitis, encephalitis, or head trauma.
Correct Answer is {"dropdown-group-1":"A"}
Explanation
Choice A reason: Diffusion is the process by which small ions such as glucose, oxygen, and carbon dioxide redistribute themselves through semipermeable membranes from areas of higher concentration to areas of lower concentration. This is how these molecules move across the cell membrane and the capillary wall.
Choice B reason: Osmosis is the process by which water moves through semipermeable membranes from areas of lower solute concentration to areas of higher solute concentration. This is how water balance is maintained across the cell membrane and the capillary wall.
Choice C reason: Blood pressure is the force exerted by the blood on the walls of the blood vessels. It is not a process by which small ions redistribute themselves through semipermeable membranes, but rather a factor that influences the movement of fluids and solutes across the capillary wall.
Choice D reason: Rehydration is the process of restoring the fluid balance in the body by drinking fluids or receiving intravenous fluids. It is not a process by which small ions redistribute themselves through semipermeable membranes, but rather a treatment for dehydration.
