A nurse is caring for a client who is taking sertraline and reports a desire to begin taking supplements.
Which of the following supplements should the nurse advise the client to avoid?

Hyponatremia is a condition where the sodium level in the blood is too low, which can cause confusion, lethargy, seizures, and coma. A hypertonic solution is a fluid that has a higher concentration of solutes than the blood, which can help raise the sodium level and reduce the brain swelling caused by hyponatremia. Therefore, improved cognition indicates that the treatment is effective.

Choice B. Cardiac arrhythmias absent.

Cardiac arrhythmias are not a common symptom of hyponatremia unless it is severe or rapid in onset.

Therefore, their absence does not necessarily indicate that the treatment is effective.

Choice C. Decreased vomiting.

Vomiting can be a cause or a consequence of hyponatremia, depending on the underlying condition.

Decreased vomiting may indicate that the patient is less nauseated, but it does not reflect the sodium level or the brain status.

Choice D. Absent Chvostek’s sign.

Chvostek’s sign is a facial twitching that occurs when tapping on the cheek, which indicates hypocalcemia (low calcium level).

It is not related to hyponatremia or hypertonic solution.

Normal ranges for sodium are 135 to 145 mEq/L and for calcium are 8.5 to 10.5 mg/dL.

The client has a negative sputum culture. This indicates that the client is adhering to the medication regimen because a negative sputum culture means that the client is no longer infectious and has cleared the tuberculosis bacteria from their lungs.

Choice A is wrong because testing negative for HIV does not indicate that the client is adhering to the medication regimen for tuberculosis. HIV testing is not related to tuberculosis treatment.

Choice C is wrong because having a positive purified protein derivative test does not indicate that the client is adhering to the medication regimen for tuberculosis.

A positive PPD test means that the client has been exposed to tuberculosis, but it does not indicate whether the client has an active or latent infection. Choice D is wrong because having liver function test results within the expected reference range does not indicate that the client is adhering to the medication regimen for tuberculosis.

Liver function tests are used to monitor for possible adverse effects of isoniazid and rifampin, which can cause hepatotoxicity, but they do not reflect the effectiveness of the treatment.
