What assessment finding would be most unexpected and require immediate attention in a patient presenting for a shoulder injury with visible deformity?
Swelling and bruising across the shoulder joint.
Pulse deficit to radial artery of the unaffected arm.
Inability to abduct the injured arm.
Pain rating of 5/10 with visible deformity.
The Correct Answer is B
Choice A reason: Swelling (edema) and bruising (ecchymosis) are expected physiological responses to tissue trauma, vascular rupture, and inflammatory infiltration following a shoulder injury or dislocation. These findings are consistent with the diagnosis of a traumatic injury and generally do not indicate a life-threatening or systemic complication requiring immediate emergency intervention.
Choice B reason: A pulse deficit in the unaffected limb is a highly unexpected and concerning clinical finding. In a patient with a shoulder injury, one would expect vascular integrity to be intact on the contralateral side. A pulse deficit on the opposite side suggests a systemic issue, such as an aortic dissection or a thrombus, which requires urgent diagnostic investigation.
Choice C reason: The inability to abduct the arm is a common functional deficit following shoulder trauma, such as rotator cuff tears, glenohumeral dislocation, or fractures of the humeral head. While this finding necessitates orthopedic evaluation and immobilization, it is an expected physical limitation given the mechanism of injury and the anatomy involved.
Choice D reason: A pain rating of 5/10 is a subjective finding that corresponds with the injury severity. A visible deformity is also a hallmark of joint dislocation or fracture. These findings are expected in a patient presenting with an acute traumatic shoulder injury and are not considered outliers that would necessitate immediate, non-orthopedic emergency management.

Correct Answer is C
Explanation
Choice A reason: Standing for 5 seconds is a more advanced task within a mobility assessment, requiring the client to maintain balance and bear full weight against gravity. Performing this before ensuring the client can tolerate the upright position without experiencing orthostatic hypotension would be clinically unsafe.
Choice B reason: Marching in place is a complex mobility task that tests coordination, balance, and unilateral weight-bearing. This activity is performed only after the client has demonstrated stability in sitting and standing positions, as it represents a significantly higher risk for falls if the client is not stable.
Choice C reason: Assessing a client's ability to sit on the edge of the bed for 2 minutes is the initial step in a mobility assessment to screen for orthostatic intolerance, dizziness, or syncope. This position allows the nurse to observe for signs of cardiovascular instability before progressing to more demanding upright activities like standing.
Choice D reason: Asking the client to place their feet on the floor is a component of the transition from supine to sitting. However, sitting on the edge of the bed is the comprehensive assessment action that incorporates placing the feet on the floor and allows for an observation period to determine safety.
Correct Answer is A
Explanation
Choice A reason: Serum lipase and amylase are digestive enzymes produced and secreted by the exocrine pancreas. Elevated levels of these enzymes in the blood are the hallmark diagnostic criteria for acute pancreatitis, reflecting glandular inflammation and damage, which allows the leakage of these intracellular enzymes into the systemic circulation.
Choice B reason: While the small intestine is involved in the final stages of chemical digestion using pancreatic enzymes, it does not synthesize these enzymes. Elevated levels of amylase or lipase would not typically originate from intestinal pathology, as these enzymes are produced in the pancreatic acinar cells and secreted into the duodenum.
Choice C reason: The liver is primarily responsible for bile production, detoxification, and metabolic processing. While liver enzyme elevation is common in hepatobiliary diseases, it does not involve the specific elevation of lipase or amylase, which are specifically reflective of pancreatic inflammatory processes rather than hepatocellular or biliary obstruction.
Choice D reason: The stomach secretes hydrochloric acid and pepsinogen to initiate protein digestion. Although gastric pathologies such as peptic ulcer disease can cause severe abdominal pain and nausea, they do not result in the elevated lipase and amylase levels seen in inflammatory pancreatic conditions or obstruction of the pancreatic duct.
