A nurse is teaching a class about using niacin to reduce LDL cholesterol.
The nurse should include in the teaching that which of the following conditions is a contraindication for receiving this medication?

Choice A rationale:

Almonds are not typically associated with latex allergy or cross-sensitivity. Latex cross-reactivity is more commonly seen with certain fruits such as bananas, avocados, kiwis, and chestnuts.

Choice B rationale:

Bananas are known to be cross-reactive with latex allergy. Individuals allergic to latex are more likely to have allergies to certain fruits, including bananas. This cross-sensitivity occurs due to the structural similarity between latex proteins and proteins found in these fruits.

Choice C rationale:

Hazelnuts are not commonly associated with latex cross-reactivity. While some individuals with latex allergy may also be allergic to hazelnuts, it is not a high-risk food in the context of latex cross-sensitivity.

Choice D rationale:

Strawberries are not typically associated with latex allergy or cross-reactivity. Latex cross-reactivity is more commonly seen with fruits like bananas, avocados, kiwis, and chestnuts. Strawberries are not among the high-risk foods for individuals with latex allergy.

Choice A rationale:

The statement, "I will take the medication in the morning," indicates lack of understanding. Metformin is usually taken with large meals, and taking it in the morning is not the best timing.

Choice B rationale:

The statement, "I will expect to gain weight," is incorrect. Weight gain is not an expected side effect of metformin. In fact, metformin is often associated with weight loss or weight maintenance, especially in individuals with diabetes, as it helps improve insulin sensitivity and glucose metabolism.

Choice C rationale:

The statement, "I will take the medication on an empty stomach," is incorrect for extended-release metformin tablets. Unlike immediate-release metformin, extended-release tablets should be taken with meals to reduce the risk of gastrointestinal side effects.

Choice D rationale:

The statement, "I will avoid crushing this medication," is correct. Metformin extended-release tablets should never be crushed or broken, as it can affect the way the medication is released into the body. Crushing or breaking the tablet can lead to a sudden release of a large amount of metformin, potentially causing an overdose.
