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 D
Explanation
Choice A rationale
Chewing gum can increase salivary production, and while saliva may neutralize some stomach acid, the act of chewing can stimulate swallowing and possibly exacerbate symptoms by introducing excess air into the stomach. For GERD patients, avoiding gum may help reduce bloating and gas discomfort.
Choice B rationale
Elevating the head of the bed reduces the likelihood of acid reflux during sleep by using gravity to prevent stomach contents from flowing backward into the esophagus. This strategy aligns with GERD management guidelines and reduces nighttime symptoms.
Choice C rationale
Taking antacids between meals and at bedtime helps neutralize stomach acid temporarily, providing short-term relief of GERD symptoms. While effective, long-term use without addressing dietary and lifestyle factors is not ideal for managing GERD.
Choice D rationale
Eating small meals is beneficial for GERD, as it prevents overdistension of the stomach, but having a bedtime snack contradicts GERD management principles. Late-night eating may increase the risk of acid reflux when lying down, thus requiring more teaching.
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.
