Nursing management for a patient with a bowel obstruction includes which of the following interventions?

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.

Choice A rationale

X-rays are commonly used to diagnose osteoarthritis as they effectively visualize joint space narrowing, osteophyte formation, and subchondral sclerosis, which are characteristic of OA. These imaging findings assist in confirming the diagnosis and assessing disease progression.

Choice B rationale

Lithography is not a diagnostic tool used for OA. It primarily refers to a printing method and has no relevance to imaging joints affected by osteoarthritis or diagnosing the condition scientifically.

Choice C rationale

Ultrasound can visualize soft tissues but is not routinely used for OA diagnosis. It does not provide the detailed assessment of joint degeneration seen in X-rays, making it less appropriate for identifying OA-related changes.

Choice D rationale

Echocardiograms are used to assess heart function and have no application in diagnosing osteoarthritis. They are irrelevant in imaging joint structures or evaluating degenerative joint diseases scientifically. .
