A nurse is reinforcing teaching with a client who has iron-deficiency anemia. The nurse should instruct the client that which of the following foods has the highest iron content?
3 oz chicken breast
3 oz canned tuna
3 oz pork roast
3 oz ground beef
The Correct Answer is D
Choice A Reason:
3 oz chicken breast is incorrect. Chicken breast contains iron, but its iron content is generally lower compared to red meats like beef. It contains less heme iron, which is more readily absorbed by the body, compared to the iron in red meats.
Choice B Reason:
3 oz canned tuna is incorrect. Tuna is a good source of protein but doesn't contain as much iron as red meats. While it does have some iron content, it's generally lower compared to red meats like ground beef.
Choice C Reason:
3 oz pork roast is incorrect. Pork contains iron, but its iron content might not be as high as that found in red meats like ground beef. The specific cut and preparation method can also affect the iron content, but generally, pork might not provide as much iron as beef.
Choice D Reason:
3 oz ground beef is correct. Red meat, like ground beef, generally contains higher amounts of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources. This makes ground beef a good source of iron for individuals with iron-deficiency anemia.

Correct Answer is A
Explanation
Choice A Reason:
"The organism that causes TB becomes resistant to antituberculotic medications when you only take one medication." This statement is appropriate.
Tuberculosis bacteria tend to develop resistance to single medications when used alone. Using multiple medications simultaneously helps prevent the bacteria from becoming resistant to any single drug. This strategy, known as combination therapy, is crucial in treating TB effectively and reducing the risk of drug resistance.
When TB bacteria are exposed to just one medication, they can mutate and become resistant to that specific drug. However, using a combination of medications helps ensure that if one medication fails to eliminate some bacteria due to resistance, the other drugs can still work against the resistant strains.
Preventing drug resistance is essential for successful TB treatment and to avoid the need for more complex and less effective medications if resistance develops.
Choice B Reason:
"Taking several antituberculotic medications will protect your liver from toxic effects." This statement is incorrect. While it's true that some antituberculotic medications can have hepatotoxic effects (adverse effects on the liver), the primary reason for using multiple medications in TB treatment isn't solely to protect the liver. The main goal of using multiple medications is to prevent the development of drug-resistant strains of TB bacteria. Protecting the liver is an important consideration in medication selection and monitoring but isn't the primary rationale for multiple medications.
Choice C Reason:
"People who have a severe form of TB need several antituberculotic medications, but those who have less severe TB need just one medication." This statement is incorrect. The severity of TB doesn't determine the number of medications required. The standard treatment approach for TB involves multiple medications, regardless of the severity. This approach aims to prevent the development of drug resistance, ensure effective treatment, and reduce the risk of treatment failure. Using a combination of medications is a fundamental strategy to combat TB effectively.
Choice D Reason:
"Adverse effects occur more often and are more severe when you take only one antituberculotic medication." This statement is incorrect. While it's true that adverse effects can occur with antituberculotic medications, the primary reason for using multiple medications isn't solely to reduce adverse effects. The main concern addressed by using multiple drugs is preventing the development of drug-resistant TB strains. Using a combination of medications reduces the likelihood of resistance developing and increases the effectiveness of treatment, rather than solely minimizing adverse effects.
Correct Answer is B
Explanation
Choice A Reason:
LDL (Low-Density Lipoprotein) is incorrect. This is a type of cholesterol and is not specifically monitored in relation to warfarin therapy.
Choice B Reason:
INR (International Normalized Ratio) is correct. Warfarin is an anticoagulant medication, and its dosage needs to be adjusted based on the INR levels. INR monitoring helps assess the clotting tendency of the blood and ensures that the dosage of warfarin is within the therapeutic range to prevent blood clots without causing excessive bleeding.
Choice C Reason:
BUN (Blood Urea Nitrogen) is incorrect. This value is primarily used to assess kidney function and is not directly related to monitoring warfarin therapy.
Choice D Reason:
Hct (Hematocrit) is incorrect. This measures the percentage of red blood cells in the blood and is not directly related to monitoring warfarin therapy for atrial fibrillation.
