A nurse is caring for a client who has tuberculosis and is taking isoniazid and rifampin.
Which of the following outcomes indicates that the client is adhering to the medication regimen?
The client tests negative for HIV.
The client has a negative sputum culture.
The client’s liver function test results are within the expected reference range.
The client has a positive purified protein derivative test.
The Correct Answer is B
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.

Correct Answer is C
Explanation
Taking a high-ceiling diuretic predisposes this client to developing digoxin toxicity because it can cause hypokalemia (low blood potassium level), which increases the sensitivity of the heart to digoxin. Digoxin is a medicine that is used to treat heart failure or arrhythmias (abnormal heart rhythms) by increasing cardiac contractility and controlling the heart rate. Digoxin toxicity happens when there is too much digoxin in the body and it becomes harmful, causing symptoms such as nausea, vomiting, headache, confusion, vision disturbance, and irregular heartbeat.
Choice A is wrong because taking an HMG CoA reductase inhibitor (also called a statin) does not increase the risk of digoxin toxicity.
Statins are lipid-lowering medications used to prevent coronary heart disease by blocking an enzyme involved in cholesterol synthesis.
Statins do not affect the blood potassium level or the sensitivity of the heart to digoxin.
Choice B is wrong because having a 10-year history of COPD (chronic obstructive pulmonary disease) does not increase the risk of digoxin toxicity. COPD is a lung condition that causes breathing difficulties and chronic inflammation.
COPD does not affect the blood potassium level or the sensitivity of the heart to digoxin.
Choice D is wrong because having a prolapsed mitral valve does not increase the risk of digoxin toxicity.
A prolapsed mitral valve is a condition where the valve between the left atrium and left ventricle of the heart does not close properly, allowing some blood to leak back into the atrium.
A prolapsed mitral valve does not affect the blood potassium level or the sensitivity of the heart to digoxin.
Correct Answer is A
Explanation
The nurse should advise the client to avoid taking St. John’s Wort with sertraline because it can increase the risk of a rare but serious condition called serotonin syndrome. Serotonin syndrome can cause symptoms such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, blurred vision, muscle spasm or stiffness, tremor, incoordination, stomach cramp, nausea, vomiting, and diarrhoea.
Choice B. Black cohosh is wrong because it is a herbal supplement that is used to treat menopausal symptoms and has no known interaction with sertraline.
Choice C. Coenzyme Q is wrong because it is a natural substance that is involved in energy production and has no known interaction with sertraline.
Choice D. Ginger root is wrong because it is a spice that is used to treat nausea and has no known interaction with sertraline.
