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.

Answer and Explanation

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 B

Explanation

This is because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so a central venous catheter is usually required. TPN should only be used when the intestine is unavailable or unable to absorb nutrients.

Choice A is wrong because a midline catheter is a type of peripheral catheter that can only be used for solutions with low or moderate osmolarity, not for TPN.

Choice C is wrong because subcutaneous administration is not a route for delivering TPN, which requires intravenous infusion.

Choice D is wrong because intraosseous administration is an emergency route for delivering fluids and drugs when intravenous access is not available, not for TPN.

A. Tinnitus. B. Hypotension. C. Hypokalemia. D. Bradycardia.

Correct Answer is B

Explanation

Lisinopril is an angiotensin converting enzyme (ACE) inhibitor that is used to treat high blood pressure and heart failure. It works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart. However, one of the common side effects of lisinopril is hypotension, which means low blood pressure. Hypotension can cause dizziness, faintness, or lightheadedness when getting up suddenly from a lying or sitting position. Therefore, the nurse should monitor the client’s blood pressure when administering lisinopril and report any signs of hypotension to the doctor.

Choice A is wrong because tinnitus, which means ringing or buzzing in the ears, is not a common or serious side effect of lisinopril.

Tinnitus can be caused by other factors such as ear infections, loud noises, or medications such as aspirin or antibiotics.

Choice C is wrong because hypokalemia, which means low potassium levels in the blood, is not a common or serious side effect of lisinopril. In fact, lisinopril can cause hyperkalemia, which means high potassium levels in the blood, especially in patients with kidney problems or diabetes. Hyperkalemia can cause irregular heartbeats, muscle weakness, or numbness. Therefore, the nurse should monitor the client’s potassium levels when administering lisinopril and avoid giving potassium supplements or salt substitutes that contain potassium.

Choice D is wrong because bradycardia, which means slow heart rate, is not a common or serious side effect of lisinopril.

Lisinopril does not affect the heart rate directly, but it can lower the blood pressure and improve the heart function.

Bradycardia can be caused by other factors such as heart block, sinus node dysfunction, or medications such as beta blockers or calcium channel blockers.
