An elderly client presents to the Emergency room with sepsis. The provider immediately starts the client on a broad-spectrum antibiotic but then changes the antibiotic when the culture and sensitivity results come back. The new antibiotic would be considered what type of antibiotic therapy?

A. "Why were you prescribed a sulfa drug?": Knowing the indication for the sulfa drug may provide some medical background but does not help determine the severity or nature of the allergic reaction, which is the nurse’s immediate concern for patient safety.

B. "What was your reaction when you took the sulfa drug?": This is the priority question because it identifies whether the response was a true allergic reaction (such as rash, hives, anaphylaxis) or a non-allergic side effect. Understanding the specific reaction guides safe medication administration and helps avoid cross-reactive drugs.

C. "Who is the provider that ordered it for you?": The prescriber’s identity is not relevant to determining the allergy type or its severity. The nurse’s immediate focus should be on assessing potential risks and ensuring accurate allergy documentation.

D. "When did you have a reaction?": The timing of the reaction can be useful, but it is secondary to identifying the symptoms and severity. Knowing the nature of the reaction allows the healthcare team to evaluate risk more effectively and implement precautions.

A. A client who has been complaining of frequent stools.: This medication is often prescribed to manage mild to moderate diarrhea, so frequent stools alone are not a contraindication. Instead, it may help decrease stool frequency and improve consistency.

B. A client with an intestinal obstruction.: Bismuth subsalicylate should be avoided in clients with bowel obstruction because it can worsen abdominal distention and delay gastric emptying. It may mask symptoms of a more serious underlying condition, such as perforation or ischemia.

C. An adult who is dehydrated.: While dehydration should be corrected, bismuth subsalicylate itself is not contraindicated. It may be used safely once rehydration is initiated to manage diarrhea and prevent further fluid loss.

D. A child with diarrhea associated with the flu.: Bismuth subsalicylate contains salicylate, which poses a risk for Reye’s syndrome when given to children or adolescents recovering from viral infections like influenza or varicella. This condition can lead to acute encephalopathy and liver damage.

E. A client with an allergy to aspirin.: Since bismuth subsalicylate is chemically related to salicylates, it can trigger hypersensitivity reactions in individuals allergic to aspirin. Symptoms may include rash, bronchospasm, or anaphylaxis, making it contraindicated.
