Which statement represents the advantage of prescribing Ondansetron rather than Promethazine for a client with nausea?

A. A client with acute, non-infectious diarrhea.: Loperamide is safe and effective for treating acute, non-infectious diarrhea by slowing intestinal motility. It allows increased absorption of water and electrolytes, helping to reduce stool frequency and improve consistency.

B. A client with traveler’s diarrhea.: Loperamide can be used short-term in traveler’s diarrhea when symptoms are not caused by invasive bacteria. It provides symptomatic relief by decreasing bowel movements while the underlying infection is being treated.

C. A client with an E. coli infection.: Loperamide should be avoided in clients with infectious diarrhea caused by organisms such as E. coli, Salmonella, or Shigella. Slowing intestinal motility can trap bacteria and toxins in the gut, worsening the infection and increasing the risk of toxic megacolon.

D. A client who has hyperactive bowel sounds.: Hyperactive bowel sounds alone are not a contraindication to loperamide use. They are expected with diarrhea and may actually improve as the medication reduces peristaltic activity and stool frequency.

A. Administer the vancomycin as ordered.: Administering vancomycin without clarifying the prescription could be unsafe because the patient’s history of VRE indicates resistance to this antibiotic. Giving the drug despite known resistance would be ineffective and delay appropriate treatment.

B. Notify the HCP about the patient's VRE history.: The nurse should first notify the healthcare provider, as vancomycin is ineffective against vancomycin-resistant Enterococcus. The provider may need to prescribe an alternative antibiotic, such as linezolid or daptomycin, based on culture and sensitivity results.

C. Monitor the patient for signs of an allergic reaction.: Although monitoring for allergic reactions is always important, this action is secondary in this case. The priority is to ensure the medication chosen will be effective for the patient’s specific infection.

D. Obtain a baseline renal function test.: Vancomycin can cause nephrotoxicity, so assessing renal function is standard before therapy. However, since the infection is resistant to vancomycin, evaluating kidney function is not the first or most urgent action.
