A nurse is teaching a client who has stable angina and a new prescription for nitroglycerin transdermal patches 0.8 mg/hr daily. Which of the following statements by the client indicates an understanding of the teaching?

A. Dobutamine: Dobutamine is a sympathomimetic medication used to increase cardiac output in conditions such as heart failure or cardiogenic shock. It is not indicated for the management of severe hypertension.

B. Epinephrine: Epinephrine is a sympathomimetic medication used for the management of severe allergic reactions (anaphylaxis), cardiac arrest, and severe asthma exacerbations. It is not indicated for the management of severe hypertension.
C. Dexamethasone: Dexamethasone is a corticosteroid medication used for a variety of

conditions, including inflammation, allergic reactions, and certain cancers. It is not indicated for the management of severe hypertension.
D. Nitroprusside: Nitroprusside is a potent vasodilator used for the rapid reduction of blood pressure in hypertensive emergencies, such as hypertensive crises or malignant hypertension. It acts quickly to dilate both arterial and venous vessels, leading to a rapid decrease in blood pressure. Therefore, it is the appropriate choice for this client with severe hypertension and a severe headache.

A. The client's liver function test results are within the expected reference range: While monitoring liver function tests is essential for clients taking isoniazid and rifampin due to
potential hepatotoxicity, normal liver function test results do not necessarily indicate adherence to the medication regimen. Adherence is best assessed by the client's response to treatment, such as improvement in symptoms and resolution of the infection.
B. The client has a positive purified protein derivative test: A positive purified protein derivative (PPD) test indicates exposure to Mycobacterium tuberculosis but does not provide information about the client's adherence to the medication regimen for tuberculosis treatment. Adherence to treatment is determined by factors such as medication compliance and therapeutic response.
C. The client tests negative for HIV: The client's HIV status is not directly related to adherence to the tuberculosis medication regimen. While co-infection with HIV can impact the management of tuberculosis, testing negative for HIV does not confirm adherence to tuberculosis treatment.
D. The client has a negative sputum culture: A negative sputum culture indicates the absence of viable Mycobacterium tuberculosis organisms in the sputum sample and suggests effective
treatment and adherence to the medication regimen. Monitoring sputum culture conversion is a key indicator of treatment success in tuberculosis therapy.
