What is the most appropriate method for controlling bleeding at this wound site?
Place a warm pack on the bleeding site.
Apply a tourniquet above the bleeding site.
Direct pressure or sterile pressure dressing and elevation of the extremity.
Place an ice pack on the bleeding site.
The Correct Answer is C
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.

Correct Answer is C
Explanation
Choice A rationale
Administering 1 mg of glucagon intramuscularly is unnecessary for a patient who is awake, alert, and able to swallow. Glucagon is reserved for patients who are unconscious and unable to swallow effectively to prevent choking.
Choice B rationale
Administering 25 g of dextrose IVP is unnecessary in this case because the patient is alert and able to swallow. Oral intake of carbohydrates is the preferred and safer intervention for mild hypoglycemia like 69 mg/dL.
Choice C rationale
Holding the insulin and encouraging the patient to eat provides glucose through dietary means, which is appropriate in a patient who is awake, alert, and hungry. A level of 69 mg/dL, though below normal, can be managed with oral glucose intake safely.
Choice D rationale
Calling the MD is not the immediate priority in managing mild hypoglycemia. Intervening directly to correct the glucose level with oral intake is more appropriate and effective in this situation.
Correct Answer is A
Explanation
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. .
