A nurse is reinforcing teaching to a patient undergoing a biopsy for a possible cancer diagnosis. The patient asks, "Why do I need this test?" What is the best response by the nurse?
"A biopsy is the only definitive way to diagnose cancer."
"It will determine if you have an infection instead of cancer."
"It will confirm the presence of metastasis."
"A biopsy can detect genetic mutations associated with cancer."
The Correct Answer is A
A. A biopsy involves obtaining a tissue sample for microscopic examination, which is the gold standard for confirming the presence and type of cancer.
B. While a biopsy may incidentally detect infection, it is not primarily used to differentiate infection from cancer.
C. While biopsies can identify cancer in a specific tissue, imaging studies and additional biopsies are typically needed to confirm metastasis.
D. Although molecular testing on biopsy samples can be done later to detect mutations, the primary purpose of a biopsy is to diagnose whether cancer is present.

Correct Answer is B
Explanation
A. Ketoacidosis typically presents with symptoms like nausea, vomiting, abdominal pain, fruity breath, and Kussmaul respirations—not acute shakiness or sweating.
B. The signs of sweating, tachycardia, light-headedness, and shakiness are classic early symptoms of hypoglycemia, a common complication in type 1 diabetes, especially when insulin or food intake is imbalanced.
C. Nephropathy is a chronic complication of diabetes affecting the kidneys and does not present with acute symptoms like those described.
D. Hyperglycemia usually causes polyuria, polydipsia, and fatigue but not the adrenergic (fight-or-flight) symptoms described here.
Correct Answer is C
Explanation
A. While monitoring is important, it is not the priority when the patient is symptomatic with hypotension and dizziness.
B. IV fluids may be necessary to treat hypotension, but positioning the patient safely and notifying the provider comes first to prevent falls or further deterioration.
C. The patient is showing signs of orthostatic hypotension and compensatory tachycardia. Placing the patient in a supine position helps restore cerebral perfusion and stabilize blood pressure. Immediate notification of the provider allows for prompt medical intervention.
D. Documentation and monitoring are important, but intervention is needed immediately due to symptomatic hypotension.
