The nurse is caring for a patient with hyperkalemia.
Which of the following interventions would be appropriate?
Encouraging the patient to consume a high-potassium diet.
Administering intravenous insulin and glucose.
Administering a potassium-sparing diuretic.
Encouraging the patient to limit fluid intake.
The Correct Answer is B
This is because hyperkalemia is a condition where the blood potassium level is too high.
This can cause cardiac arrhythmias, muscle weakness, and paralysis. Therefore, the nurse should administer intravenous insulin and glucose to lower the blood potassium level by shifting it into the cells.
Choice A is wrong because encouraging the patient to consume a high- potassium diet would increase the blood potassium level and worsen the condition.
Choice C is wrong because administering a potassium-sparing diuretic would prevent the excretion of excess potassium and aggravate the hyperkalemia.
Choice D is wrong because encouraging the patient to limit fluid intake is not relevant to the management of hyperkalemia and may cause dehydration.

Correct Answer is B
Explanation
An isotonic solution has the same concentration of solutes as the blood plasma. 0.9% sodium chloride solution is an example of an isotonic solution.
It is used to supply water and salt to the body and to prevent hypotension induced by spinal anaesthesia.
Choice A is wrong because a hypotonic solution has a lower concentration of solutes than the blood plasma.
It can cause water to move into the cells and cause them to swell.
Choice C is wrong because a hypertonic solution has a higher concentration of solutes than the blood plasma.
It can cause water to move out of the cells and cause them to shrink.
Choice D is wrong because a colloid solution contains large molecules that do not pass through the capillary walls.
It is used to increase the blood volume and pressure in cases of shock or severe blood loss.
Correct Answer is A
Explanation
Metabolic acidosis is a condition in which there is excess acid in the body fluids.
It causes rapid breathing, confusion, tiredness, headache, and increased heart rate.
Rapid breathing is a compensatory mechanism that helps to lower the carbon dioxide levels and increase the pH of the blood.
Choice B is wrong because decreased respiratory rate would worsen the acidosis by retaining more carbon dioxide and lowering the pH of the blood.
Choice C is wrong because normal respiratory rate would not be adequate to compensate for the metabolic acidosis and would result in acidemia (low blood pH).
Choice D is wrong because irregular respiratory rate is not a typical response to metabolic acidosis and could indicate other problems such as brain injury or drug overdose.
