What is the primary use of a cathartic in patient care?

1. Inhibit coughing

2. Promote elimination of urine

3. Stimulate defecation

4. Induce vomiting

The correct answer is: Stimulate defecation

The primary use of a cathartic in patient care is to stimulate defecation. Cathartics are substances that are specifically designed to promote bowel movements and are commonly utilized to relieve constipation or prepare a patient for medical procedures involving the gastrointestinal tract, such as imaging studies or surgeries. By enhancing the peristaltic activity of the intestines, cathartics help ensure that the bowels are cleared effectively and that the patient does not experience complications during procedures. In the context of patient care, ensuring that a patient has regular bowel movements is crucial for comfort and may be necessary for certain medical evaluations. While some medications may address other bodily functions, such as promoting urination or inhibiting coughing, the specific action of a cathartic focuses solely on facilitating the elimination of fecal matter from the digestive system.
