The physician orders strict I & O for a critically ill patient with CHF on a furosemide drip.
The RN knows that it would be appropriate to ask the physician for an order to place a Foley catheter for this patient.
True.
False.
The Correct Answer is A
Choice A rationale
Strict monitoring of intake and output in CHF patients with furosemide therapy prevents fluid overload and underhydration. Foley catheter placement accurately quantifies urine output, crucial in critically ill patients with diuretic-induced fluid shifts. This ensures precise fluid balance adjustments, improving patient outcomes.
Choice B rationale
Omitting Foley catheter placement in CHF patients risks inaccurate fluid balance monitoring. Furosemide causes frequent, unpredictable urination, complicating intake-output tracking without direct measurement. This approach undermines effective management of diuretic therapy and fluid overload prevention in critical settings. .

Correct Answer is A
Explanation
Choice A rationale
Contact isolation prevents the transmission of Clostridium difficile spores, a significant source of nosocomial infections. Private rooms reduce cross-contamination risks.
Choice B rationale
Antidiarrheal use is contraindicated in Clostridium difficile infection as it may worsen colitis by retaining toxins. Prompt stool elimination is vital.
Choice C rationale
Antibiotics are used to treat Clostridium difficile but educating the patient about antibiotic cessation is inappropriate as their use is essential for infection control.
Choice D rationale
Stool softeners are unnecessary since diarrhea is already present, and further softening may exacerbate fluid and electrolyte loss.
Correct Answer is B
Explanation
Choice A rationale
Mixing insulin glargine and lispro in the same syringe is contraindicated due to their incompatible chemical formulations. Glargine’s acidic pH alters lispro’s effectiveness when mixed, impairing glycemic control. Separate administration preserves their individual pharmacokinetics and therapeutic actions.
Choice B rationale
Separate injections ensure each insulin maintains its unique action profile. Glargine provides basal control, while lispro manages rapid postprandial spikes. Their chemical incompatibility mandates separate administration, optimizing glycemic management and reducing potential adverse effects from mixed formulations.
