A nurse is reviewing the lab results of a client with suspected acute pancreatitis.
Which additional lab results would support this diagnosis? Select all that apply.
Elevated WBC count.
Decreased hematocrit.
Decreased serum amylase.
Elevated serum lipase.
Elevated serum triglycerides.
Elevated serum glucose.
Correct Answer : A,D,E,F
Diagnosing acute pancreatitis involves analyzing inflammatory markers, pancreatic enzymes, and metabolic changes. Knowledge of systemic inflammatory response syndrome and the endocrine/exocrine functions of the pancreas is necessary to identify labs indicating tissue necrosis, inflammation, and secondary metabolic disturbances.
Choice A rationale
Pancreatitis triggers a systemic inflammatory response, leading to leukocytosis. An elevated white blood cell count (normal range 5,000 to 10,000 cells/mm) is a common finding indicating active inflammation or secondary infection within the pancreatic tissue.
Choice B rationale
In acute pancreatitis, hematocrit often increases rather than decreases due to hemoconcentration. Fluid shifts from the intravascular space into the peritoneal cavity (third spacing) cause a relative rise in hematocrit, indicating significant volume depletion.
Choice C rationale
Serum amylase (normal range 30 to 110 U/L) typically increases rapidly within hours of symptom onset in pancreatitis. A decreased level is not supportive of this diagnosis; levels usually rise three times the upper limit.
Choice D rationale
Serum lipase (normal range 0 to 160 U/L) is a highly specific marker for pancreatic damage. In acute pancreatitis, lipase levels rise significantly and remain elevated longer than amylase, making it a primary diagnostic indicator.
Choice E rationale
Hypertriglyceridemia is both a cause and a result of acute pancreatitis. Serum triglycerides exceeding 1,000 mg/dL can precipitate an attack. Elevated levels support the diagnosis and help identify the potential underlying metabolic etiology.
Choice F rationale
The pancreas produces insulin via islets of Langerhans. Inflammation impairs endocrine function, leading to hyperglycemia (normal fasting glucose 70 to 99 mg/dL). Elevated glucose is a common secondary finding in acute pancreatic injury.

Correct Answer is B
Explanation
Delegation to unlicensed assistive personnel requires understanding the scope of practice regarding stable vs unstable clients. Knowledge of the nursing process, specifically the difference between assessment or teaching and implementation of standard safety tasks, is required for this decision.
Choice A rationale
Teaching is a core nursing responsibility that requires specialized knowledge and clinical judgment. UAPs cannot perform initial or formal education on therapeutic techniques like the chin tuck, as they are not trained to evaluate the effectiveness of teaching.
Choice B rationale
Positioning a client upright and providing supervision during meals are standard safety tasks within the UAP scope of practice. This intervention supports safe swallowing while allowing the UAP to assist the client in a stable, repetitive manner.
Choice C rationale
Evaluation is the final step of the nursing process and must be performed by a registered nurse. Identifying signs of aspiration requires clinical observation and interpretation of physiological data, which exceeds the training and role of the UAP.
Choice D rationale
Assessment of swallowing ability is a complex task that requires clinical expertise and judgment. The registered nurse must perform the initial and ongoing assessments to determine the client's risk level and the safety of the current feeding plan..
Correct Answer is A
Explanation
Prioritizing interventions for a client on anticoagulant therapy presenting with neurological changes requires recognizing high-risk complications. Knowledge of anticoagulation side effects and the signs of intracranial hemorrhage is essential to ensure rapid stabilization and prevent irreversible neurological damage or death from bleeding.
Choice A rationale: New blurred vision and delayed responses in a client receiving anticoagulants are hallmark signs of potential intracranial hemorrhage. Notifying the provider immediately is the priority action to facilitate urgent diagnostic imaging and potential reversal of anticoagulation therapy.
Choice B rationale: Administering acetaminophen may mask a worsening headache and ignores the underlying life-threatening cause of the neurological changes. Furthermore, some formulations can interfere with coagulation, and clinical focus must remain on identifying the source of the vision changes.
Choice C rationale: Documentation and monitoring are insufficient when a client displays acute neurological decline while on blood thinners. Delaying intervention allows for continued intracranial bleeding and brain herniation, making passive monitoring a dangerous and inappropriate response in this emergency.
Choice D rationale: Waiting one hour to reassess a client with suspected intracranial bleeding is a critical failure in nursing judgment. Neurological status can deteriorate within minutes during a hemorrhagic event, requiring immediate medical evaluation rather than delayed observation and assessment.
