Which type of laxative causes peristalsis by irritating the bowel?

A) Low-back pain:
Low-back pain is not a common manifestation of an allergic reaction to a blood transfusion. It may be associated with other conditions, such as musculoskeletal issues or renal complications, but it is not typically addressed by diphenhydramine administration during transfusion.

B) Fever:
While fever can occur as a manifestation of an adverse reaction to a blood transfusion, it is more commonly associated with non-allergic transfusion reactions such as transfusion-related acute lung injury (TRALI) or bacterial contamination of the blood product. Diphenhydramine is not specifically indicated for the prevention of fever during transfusion.

C) Dyspnea:
Dyspnea, or difficulty breathing, can occur as a manifestation of a severe allergic reaction or anaphylaxis during a blood transfusion. However, diphenhydramine alone may not be sufficient to prevent or treat severe respiratory symptoms associated with anaphylaxis. In such cases, prompt medical intervention and administration of epinephrine may be necessary. Diphenhydramine primarily targets histamine-mediated symptoms such as urticaria and itching.

D) Urticaria.
Urticaria, commonly known as hives, is a skin reaction characterized by raised, itchy welts that can occur as a result of an allergic or hypersensitivity reaction. During a blood transfusion, if the recipient's immune system reacts to foreign proteins in the transfused blood, it can lead to an allergic reaction characterized by symptoms such as urticaria, itching, flushing, and sometimes more severe reactions like anaphylaxis.
Diphenhydramine is an antihistamine medication that works by blocking the effects of histamine, a chemical released by the body during allergic reactions. By administering diphenhydramine before the blood transfusion, the nurse aims to prevent or minimize the occurrence of urticaria and other allergic symptoms.

A) Treatment with PPIs to decrease stomach acid:
Pancreatic insufficiency is not primarily related to excess stomach acid production, so treatment with proton pump inhibitors (PPIs) to decrease stomach acid would not address the underlying cause of the condition.

B) Treatment with stimulant laxatives:
Pancreatic insufficiency is not typically associated with constipation or the need for stimulant laxatives. While malabsorption of fats due to pancreatic insufficiency can lead to loose stools or diarrhea, treatment with laxatives is not indicated for this condition.

C) Replacement therapy with pancreatic enzymes.
Pancreatic insufficiency is a condition where the pancreas does not produce enough digestive enzymes to properly digest food. Replacement therapy with pancreatic enzymes is the mainstay of treatment for pancreatic insufficiency. These pancreatic enzyme supplements help in the digestion and absorption of nutrients from food by compensating for the deficient enzymes produced by the pancreas. By taking pancreatic enzyme supplements with meals, the client can improve digestion and prevent malnutrition associated with pancreatic insufficiency.

D) Decrease food intake:
Decreasing food intake would not address the underlying cause of pancreatic insufficiency, which is the deficiency of pancreatic enzymes needed for proper digestion. In fact, decreasing food intake could exacerbate malnutrition and nutrient deficiencies in individuals with pancreatic insufficiency. The primary goal of treatment is to improve digestion and nutrient absorption by providing supplemental pancreatic enzymes with meals.
