A lumbar puncture is performed on a client with suspected bacterial meningitis, and cerebrospinal fluid (CSF) is obtained for analysis. The nurse determines that the diagnosis is confirmed if which findings are noted?

Choice A Reason: Irrigating the fistula with 3 mL of normal saline solution is not a correct way to assess the patency of the fistula, as it may cause bleeding, infection, or dislodgement of the fistula.

Choice B Reason: Flushing the fistula with 1 mL of heparin solution once per shift is not a correct way to assess the patency of the fistula, as it may cause clotting, infection, or allergic reaction.

Choice C Reason: Infusing 50 mL of normal saline once per 24 hours is not a correct way to assess the patency of the fistula, as it may cause fluid overload, hypertension, or edema.

Choice D Reason: Palpating for a vibrating sensation at the fistula site is a correct way to assess the patency of the fistula, as it indicates that there is adequate blood flow through the fistula. This sensation is also known as a thrill.

Choice A Reason: Determining the client's calcium level is the appropriate action for the nurse to take, as it may indicate hypocalcemia, which is a possible complication of thyroidectomy due to accidental removal or damage of the parathyroid glands. Hypocalcemia can cause muscle spasms, tingling, numbness, or tetany.

Choice B Reason: Monitoring the client's peripheral pulses is not the appropriate action for the nurse to take, as it does not address the cause of muscle spasms or provide any relief.

Choice C Reason: Administering IV normal saline solution is not the appropriate action for the nurse to take, as it does not correct hypocalcemia or prevent further complications.

Choice D Reason: Giving the client an oral potassium supplement is not the appropriate action for the nurse to take, as it may worsen hypocalcemia or cause hyperkalemia, which can affect cardiac function and muscle contraction.
