A nurse is reinforcing teaching about a low-cholesterol diet with a client who had a myocardial infarction. Which of the following meal selections by the client indicates an understanding of the teaching?

Choice A reason: This is the correct finding, because rifampin is an antibiotic that can cause red-orange discoloration of urine, saliva, sweat, tears, and other body fluids. This is a harmless and expected adverse effect of rifampin, and does not indicate any damage to the kidneys or liver. The client should be informed about this effect and advised to wear soft contact lenses, as rifampin can stain them permanently.

Choice B reason: This is an incorrect finding, because increased ecchymosis, or bruising, is not a harmless or expected adverse effect of rifampin, but a sign of bleeding disorder or thrombocytopenia, which is a rare but serious complication of rifampin. Rifampin can interfere with the synthesis of vitamin K, which is essential for blood clotting, and cause bleeding problems. The client should report any signs of bleeding, such as ecchymosis, petechiae, hematuria, or epistaxis, to the provider.

Choice C reason: This is an incorrect finding, because yellow appearance of the sclerae, or jaundice, is not a harmless or expected adverse effect of rifampin, but a sign of liver damage or hepatitis, which is a rare but serious complication of rifampin. Rifampin can cause inflammation and injury to the liver cells, and impair the metabolism and excretion of bilirubin, which is a yellow pigment that accumulates in the skin and eyes when the liver is damaged. The client should report any signs of liver dysfunction, such as jaundice, dark urine, pale stools, or abdominal pain, to the provider.

Choice D reason: This is an incorrect finding, because lack of energy, or fatigue, is not a harmless or expected adverse effect of rifampin, but a sign of anemia or hypothyroidism, which are rare but serious complications of rifampin. Rifampin can cause hemolytic anemia, which is a condition that occurs when the red blood cells are destroyed faster than they are produced, and hypothyroidism, which is a condition that occurs when the thyroid gland produces insufficient thyroid hormone. The client should report any signs of anemia or hypothyroidism, such as fatigue, weakness, pallor, or cold intolerance, to the provider.

Choice A reason: This is an incorrect route, because maternal-fetal transmission of hepatitis A is very rare and occurs only if the mother has acute hepatitis A during the third trimester of pregnancy.

Choice B reason: This is the correct route, because fecal-oral contamination of hepatitis A is the most common mode of transmission. Hepatitis A is a viral infection that affects the liver and is spread through ingestion of contaminated food or water, or contact with infected feces.

Choice C reason: This is an incorrect route, because genital sexual contact of hepatitis A is uncommon and occurs only if there is oral-anal contact with an infected person.

Choice D reason: This is an incorrect route, because blood to blood transmission of hepatitis A is also uncommon and occurs only if there is exposure to infected blood or blood products, such as through needle sharing or transfusion.
