A patient develops constipation after taking a daily iron supplement prescribed by the physician. Which term best describes the patient’s reaction to the supplement?
Side effect
Therapeutic effect
Adverse reaction
Toxicity
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A rationale:
Stage 1 pressure injury:
Non-blanchable erythema of intact skin: This means that when you press on the area, the redness does not disappear. It is persistent and remains even after pressure is relieved, unlike other types of skin redness that may blanch temporarily.
Intact skin: This is a crucial characteristic of Stage 1. The skin is not broken or open, differentiating it from more advanced stages.
Commonly over bony prominences: The malleolus, or ankle bone, is a bony prominence that is susceptible to pressure injuries due to its location and potential for prolonged pressure.
Explanation:
Non-blanchable erythema: The description of the redness as "non-blanchable" is the key indicator of a Stage 1 pressure injury. Blanchable erythema, which disappears when pressure is applied, can be due to other causes like inflammation or skin irritation, but non-blanchable erythema signals a deeper issue with the tissue.
Intact skin: The fact that the skin is intact rules out Stages 2, 3, and 4, which all involve some degree of skin breakdown.
Location on a bony prominence: The malleolus is a common site for pressure injuries because it's a bony area that often bears weight, especially in those with limited mobility or those confined to beds or chairs.
Additional Information:
Pressure injuries, also known as pressure ulcers or bed sores, are areas of damage to the skin and underlying tissue caused by prolonged pressure.
They are a common problem in healthcare settings, particularly among patients with limited mobility. Early identification and intervention are crucial to prevent progression to more severe stages.
