Which herbal supplement is likely to exacerbate symptoms for a patient with rheumatoid arthritis?

Choice A rationale:

Irrigating with sterile saline before swabbing can dilute the wound specimen and reduce the accuracy of the culture results. This is because the saline can wash away some of the bacteria that are present in the wound, making it more difficult to identify the specific bacteria that are causing the infection.

Additionally, swabbing the center of the wound may not collect a representative sample of the bacteria present, as bacteria can often be found in higher concentrations at the edges of the wound. This is because the edges of the wound are often where the tissue is most damaged and where the bacteria are able to enter the body more easily.

Choice B rationale:

Obtaining a sample of the drainage from the dressing on the wound may not be as accurate as collecting a sample directly from the wound. This is because the drainage may contain bacteria from the surrounding skin or environment, which could contaminate the culture results.

Additionally, the drainage may not contain a representative sample of the bacteria present in the wound, as some bacteria may not be able to drain out of the wound.

Choice D rationale:

Collecting a tissue sample from the wound during a surgical procedure is the most accurate way to obtain a culture. However, this is not always feasible or necessary.

It is often possible to obtain an accurate culture by collecting a sample from the wound using a sterile swab. This is a less invasive procedure and can be done at the bedside.

Choice A rationale:

Side effect: A side effect is an effect of a drug that is secondary to the main intended effect. It is usually predictable and may be either beneficial or harmful. However, constipation is not a common or expected side effect of iron supplements. It is more likely to be an adverse reaction.

Choice B rationale:

Therapeutic effect: The therapeutic effect is the intended effect of a drug, the one that is desired to treat the condition. In this case, the therapeutic effect of the iron supplement would be to increase the patient's iron levels. Constipation is not the desired effect of the iron supplement, so it is not a therapeutic effect.

Choice C rationale:

Adverse reaction: An adverse reaction is an unwanted or harmful reaction to a drug that is not necessarily predictable. It can range from mild to severe. Constipation is a common adverse reaction to iron supplements. It is thought to be caused by the iron binding to undigested food in the intestines, making it harder to pass stool.

Choice D rationale:

Toxicity: Toxicity refers to a poisonous or harmful effect of a drug. It is usually caused by taking too much of a drug or by a drug interacting with another drug or substance. Constipation is not a sign of iron toxicity. Iron toxicity can cause symptoms such as nausea, vomiting, abdominal pain, and diarrhea.
