A client is experiencing metabolic acidosis.
The nurse anticipates that the client’s respiratory rate will be:
Increased.
Decreased.
Normal.
Irregular.
The Correct Answer is A
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.

Correct Answer is A
Explanation
Clearance = urine flow rate x urine concentration / plasma concentration. This is the formula for calculating the renal clearance of a substance that is neither reabsorbed nor secreted by the tubules. Renal clearance is the volume of plasma that would have to be filtered by the glomeruli each minute to account for the amount of that substance appearing in the urine each minute.
Choice B is wrong because it has the urine concentration and plasma concentration inverted.
This would give an incorrect value for renal clearance.
Choice C is wrong because it has the plasma flow rate instead of the urine flow rate.
Plasma flow rate is not directly related to renal clearance.
Choice D is wrong because it has both the plasma flow rate and the urine concentration and plasma concentration inverted.
This would give an incorrect value for renal clearance.
Normal ranges for renal clearance vary depending on the substance, age, sex, and body size.
For example, the normal range for creatinine clearance is 85-125 mL/min for males and 75-115 mL/min for females.
Correct Answer is B
Explanation
Hyponatremia is a condition where the serum sodium level is below 135 mEq/L, which can affect the normal functioning of cells, muscles, and organs.
Administering intravenous fluids with a high sodium content can help restore the sodium balance and prevent complications such as confusion, seizures, and coma.
Choice A is wrong because encouraging the patient to consume a low-sodium diet would worsen the hyponatremia and increase the risk of electrolyte imbalance.
Choice C is wrong because administering a diuretic medication to increase urine output would cause further fluid and sodium loss and exacerbate the hyponatremia.
Choice D is wrong because encouraging the patient to increase fluid intake would dilute the sodium concentration and lower the serum sodium level.
