Which diagnostic assessment method is commonly used for osteoarthritis (O
X-ray.
Lithography.
Ultrasound.
Echocardiogram.
The Correct Answer is A
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. .

Correct Answer is A
Explanation
Choice A rationale
Using a Foley catheter can help prevent skin breakdown caused by prolonged contact with urine in incontinent patients, especially if they are confused or non-ambulatory and unable to use other urinary devices. Maintaining intact skin is crucial to avoiding infections and pressure injuries, making a Foley catheter a suitable intervention in specific cases when prescribed.
Choice B rationale
Foley catheters are not inherently inappropriate but must be prescribed judiciously due to risks like urinary tract infections. While alternative methods may be preferable, this intervention is justified for incontinent, immobile patients with compromised mental status to protect skin integrity. It aligns with clinical guidelines and patient-specific needs.
Correct Answer is C
Explanation
Choice A rationale
Applying a warm pack is inappropriate for controlling active bleeding, as it can exacerbate blood flow to the site, worsening the hemorrhage rather than controlling it effectively.
Choice B rationale
Using a tourniquet above the bleeding site is a last-resort method typically reserved for life-threatening bleeding. It may cause complications such as nerve damage or ischemia, so other measures are prioritized first.
Choice C rationale
Direct pressure or sterile pressure dressing with elevation minimizes blood loss effectively by compressing the damaged vessels, promoting clot formation, and utilizing gravity to reduce the pressure at the wound site. It is the recommended first-line method.
Choice D rationale
Placing an ice pack on the bleeding site may reduce localized blood flow by inducing vasoconstriction but is less effective than direct pressure for stopping active hemorrhage. It is secondary to other control measures.
