A client has been prescribed isoniazid (INI) for tuberculosis. Which foods should the client avoid while taking this medication, as they are high in tyramine? (Select All that Apply.)

Chocolate

Aged cheese

Bananas

Red meat

White wine

Answer and Explanation

Correct Answer : A,B,C,E

A. Chocolate:

Chocolate contains tyramine, a substance that can interact with certain medications like monoamine oxidase inhibitors (MAOIs) to increase blood pressure. While isoniazid itself does not directly interact with tyramine, it is often recommended to avoid tyramine-rich foods to prevent potential interactions with other medications or to minimize potential risks. Therefore, clients taking isoniazid are advised to avoid consuming chocolate to reduce the risk of adverse effects.

B. Aged cheese:

Aged cheeses, such as cheddar, Swiss, and blue cheeses, are high in tyramine. Tyramine levels increase as cheeses age, and consuming aged cheeses can lead to tyramine buildup in the body, potentially causing hypertensive crisis when combined with certain medications like MAOIs. While isoniazid is not an MAOI, the cautionary advice to avoid tyramine-rich foods is often extended to individuals taking isoniazid to minimize potential risks.

C. Bananas:

Bananas contain tyramine, although in lower amounts compared to some other foods. However, it is still advisable for individuals taking isoniazid to avoid consuming bananas and other tyramine-rich foods to reduce the risk of potential interactions or adverse effects.

D. Red meat:

Red meat is not typically high in tyramine compared to other foods like aged cheeses, certain processed meats, and fermented foods. While some sources suggest limiting consumption of aged or fermented meats, fresh red meat is generally considered safe to consume while taking isoniazid.

E. White wine:

While red wine is more commonly associated with tyramine content, white wine can also contain tyramine and other biogenic amines. Like other tyramine-rich foods, white wine consumption should be limited or avoided by individuals taking isoniazid to minimize the risk of tyramine-related interactions or adverse effects.

Correct Answer is A

Explanation

A. Permanent, inheritable changes to DNA:

Mutations are alterations or changes in the DNA sequence of an organism's genome. These changes can be permanent and heritable, meaning they are passed on to offspring during reproduction. Mutations can occur spontaneously or be induced by various factors such as environmental agents, radiation, or errors in DNA replication or repair mechanisms. These changes can lead to variations in traits among individuals within a population and are essential for the process of evolution.

B. An organism that is capable of causing disease:

This definition refers to the term "pathogen." Pathogens are organisms, such as bacteria, viruses, fungi, or parasites, that are capable of causing disease in their hosts. Pathogens can infect humans, animals, plants, or other organisms and can lead to a wide range of diseases, from mild infections to life-threatening illnesses.

C. The severity of a disease that an organism is able to cause:

This definition refers to the term "virulence." Virulence is a measure of the severity or harmfulness of a pathogen, indicating its ability to cause disease in a host organism. Highly virulent pathogens are more likely to cause severe illness or death, while less virulent pathogens may cause milder symptoms or asymptomatic infections. Virulence factors, such as toxins, adhesion molecules, or evasion mechanisms, contribute to the pathogen's ability to cause disease.

D. A substance that can inhibit the growth of bacteria:

This definition refers to the term "antibiotic." Antibiotics are chemical substances produced by microorganisms, fungi, or synthesized in the laboratory that can inhibit the growth of or kill bacteria. Antibiotics are commonly used to treat bacterial infections and work by targeting specific bacterial structures or metabolic processes, thereby disrupting bacterial growth and survival. However, antibiotics are not mutations; instead, they are therapeutic agents used to combat bacterial infections.

Correct Answer is ["0.6"]

Explanation

To calculate the volume of diazepam solution needed, we can use the formula:

Volume (mL) = Total dose (mg) / Concentration (mg/mL)

Given:

Total dose = 3 mg

Concentration = 5 mg/mL

Plugging the values into the formula:

Volume (mL) = 3 mg / 5 mg/mL

Volume (mL) = 0.6 mL

The nurse should administer: 0.6 mL
