The nurse is assessing a client with hypocalcemia.
What clinical manifestation would the nurse expect to note in this client?
Positive Trousseau's sign.
Hyperactive deep tendon reflexes.
Hyperactive bowel sounds.
Muscle twitching.
The Correct Answer is A
Trousseau’s sign is a test for hypocalcemia that involves inflating a blood pressure cuff on the arm and observing for carpal spasm. A positive sign indicates low calcium levels in the blood, which can cause neuromuscular irritability.
Choice B is wrong because hyperactive deep tendon reflexes are a sign of hypomagnesemia, which is a low level of magnesium in the blood.
Choice C is wrong because hyperactive bowel sounds are a sign of hyperkalemia, which is a high level of potassium in the blood.
Choice D is wrong because muscle twitching can be caused by many factors, such as anxiety, caffeine, or electrolyte imbalance, and is not specific to hypocalcemia.

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
This is a priority nursing intervention for a client with acute kidney injury (AKI) because it helps to assess the renal function and fluid status of the client. Urine output is also an indicator of the response to treatment and the need for further interventions.
Choice A is wrong because pain medication is not a priority intervention for AKI unless the client has other conditions that cause pain.
Pain medication may also have adverse effects on the kidney function and should be used with caution.
Choice C is wrong because ambulation is not a priority intervention for AKI and may not be appropriate for a client who is fluid overloaded or hypotensive.
Ambulation may also increase the risk of falls and injury in a client who is confused or fatigued.
Choice D is wrong because assisting with meals is not a priority intervention for AKI and may not be necessary for a client who has adequate oral intake.
A client with AKI may also have dietary restrictions such as low protein, low potassium, low sodium, and low phosphorus, which should be considered when providing meals.
