What is the evaluation of medication e昀昀ectiveness of senna?

Correct Answer: C

Rationale: Senna is a natural laxative commonly used to relieve constipation. Its primary mechanism of action is to stimulate the muscles in the intestines, leading to increased contractions and bowel movements. The evaluation of medication effectiveness for senna would typically focus on its ability to promote bowel movements and alleviate constipation. This would manifest as patients experiencing solid, formed bowel movements after taking senna. The options of decreased GI pain and irritation, healing of ulcers, and prevention of nausea and vomiting are not the primary expected outcomes when evaluating the effectiveness of senna as a medication for constipation.

Correct Answer: B

Rationale: "Analgesic, Antipyretic" describes the pharmacologic class of the drug, indicating that it has pain-relieving (analgesic) and fever-reducing (antipyretic) properties. Pharmacologic class refers to the category or group of medications that have similar pharmacological effects or act on the body in a similar way. In this case, the drug is categorized as an analgesic and antipyretic, which defines its primary therapeutic actions.

Correct Answer: D

Rationale: A concentrated solution of sugar in water is known as a syrup. Syrup is commonly used in cooking and baking to add sweetness and moisture to various dishes. It is created by dissolving sugar in water over heat until a thick, sweet liquid is formed. Syrups are often used in beverages, desserts, and even as a sweetener for certain medications.

Correct Answer: D

Rationale: Phenylbutazone is a nonsteroidal anti-inflammatory drug (NSAID) known for its potential to cause bone marrow depression. Bone marrow depression is a serious side effect that can lead to decreased production of blood cells, including white blood cells, red blood cells, and platelets. This can result in an increased risk of infections, anemia, and bleeding disorders. Therefore, phenylbutazone should be used cautiously and under close monitoring to avoid this complication. Aspirin, Colchicine, Ibuprofen, and Acetaminophen are not typically associated with causing bone marrow depression as a side effect.

Correct Answer: C

Rationale: Mucositis, inflammation of the mucous membranes, is a common side effect of chemotherapy. Using alcohol-based mouthwash can exacerbate mucositis by causing further irritation and dryness. The patient should be taught to use gentle, non-alcoholic mouth rinses, such as saline or baking soda solutions, to soothe the mucosa. Ice pops, ice chips, and a soft toothbrush are appropriate measures to manage mucositis. The nurse should provide additional teaching to correct the misconception about alcohol-based mouthwash and emphasize the importance of gentle oral care.
