A nurse is assisting with the care of a middle-aged adult client who is being admitted to the medical-surgical unit from the emergency department. The nurse is reviewing the client's medical records. Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

Rationale for correct condition Hyperglycemia is the presence of excess glucose in the bloodstream, typically defined by a random plasma glucose level exceeding 200 mg/dL. This client presents with a blood glucose of 235 mg/dL and an elevated HbA1c of 8.4 percent. The elevated HbA1c confirms chronic poor glycemic control over the past 90 days. Random blood glucose of 235 mg/dL exceeds the normal range of 74 to 106 mg/dL. Fatigue, blurred vision, and headache are classic clinical manifestations of elevated serum glucose. The client has stopped taking regular insulin, leading to insulin deficiency and subsequent glucose elevation. Normal vital signs and clear urinalysis rule out acute infection or cardiovascular decompensation. Rationale for correct actions Education and physical assessment are critical for managing chronic hyperglycemia and preventing long-term microvascular complications. Checking for sensation identifies peripheral neuropathy, while education empowers the client to recognize early signs of metabolic instability. Client education regarding hyperglycemia symptoms like polyuria and polydipsia prevents future emergency admissions. Lack of insulin strips suggests a need for identifying symptoms when monitoring technology is unavailable. Assessing foot sensation using a monofilament identifies loss of protective sensation due to glycosylation of nerve fibers. Hyperglycemia causes damage to small vessels and nerves, increasing the risk of diabetic foot ulcers. Early detection of neuropathy allows for specialized podiatric interventions to prevent infection or amputation. Identifying financial barriers ensures the client receives resources for medication and supplies like insulin strips. Rationale for correct parameters Monitoring blood glucose and urinary output provides direct evidence of the effectiveness of insulin therapy and the resolution of osmotic diuresis. These metrics track the physiological response to the new insulin glargine dosage. Fingerstick blood glucose monitoring is essential to titrate sliding scale regular insulin and evaluate glargine efficacy. Target ranges are usually 140 to 180 mg/dL for hospitalized non-critically ill patients to avoid hypoglycemia. Monitoring urination is vital because glucose acts as an osmotic diuretic when levels exceed 180 mg/dL. As blood glucose levels normalize, the frequency and volume of urination should decrease to baseline. Polyuria leads to fluid volume deficit and electrolyte imbalances like hypokalemia or hyponatremia. Precise intake and output measurement ensures the client maintains adequate hydration during the transition to higher insulin doses. Rationale for incorrect conditions Anemia, heart failure, and urinary tract infection are excluded based on normal laboratory values and stable physical findings. Diagnostic results confirm that physiological systems related to these conditions are within normal limits. Anemia is ruled out because the hemoglobin is 14.2 g/dL and hematocrit is 42.6 percent. These values are within the normal reference range of 12 to 18 g/dL and 37 percent to 52 percent. Clear lungs on x-ray and a normal BNP of 52 pg/mL exclude acute heart failure. Heart failure typically presents with BNP levels greater than 100 pg/mL and evidence of pulmonary congestion or edema. Urinary tract infection is unlikely due to negative nitrates, negative leukocyte esterase, and clear urine appearance. Normal white blood cell count of 6000/mm³ further suggests the absence of an active infectious process. Type 1 diabetes is a chronic diagnosis, whereas the current acute problem is specifically the state of hyperglycemia. Rationale for incorrect actions Elevating the head of the bed, low-sodium diets, and iron-rich foods address conditions the client does not currently manifest. These interventions do not target the primary issue of elevated blood glucose levels. Elevating the head of the bed is an intervention for respiratory distress or heart failure. A low-sodium diet is indicated for fluid volume overload or hypertension, not acute hyperglycemia. Iron-rich foods are used to treat iron-deficiency anemia, which is not present in this client. These actions do not lower serum glucose or address the lack of insulin therapy. They are irrelevant to the immediate metabolic needs of a client with a blood glucose of 235 mg/dL. Using these interventions would ignore the primary risk of diabetic ketoacidosis or hyperosmolar state. Rationale for incorrect parameters Blood pressure, white blood cell count, and hemoglobin are stable and do not provide data on glycemic control. Monitoring these would fail to capture the client's progress toward metabolic stabilization. The client's blood pressure is 120/72 mm Hg, which is within a healthy range and stable. White blood cell count is 6000/mm³, indicating no infection, and does not change based on insulin administration. Hemoglobin is normal at 14.2 g/dL and is not affected by short-term fluctuations in blood glucose. These parameters are relevant to urinary tract infection, sepsis, or anemia, rather than hyperglycemia. Monitoring them would not help the nurse determine if the insulin glargine dose is effective. Only blood glucose and urine output directly reflect the pathophysiological process of glucose metabolism and osmotic balance. Test-taking strategy Identify the core issue: Review labs for abnormalities. The only significant deviations are blood glucose (235 mg/dL) and HbA1c (8.4 percent). Rule out negatives: Urinalysis, WBC, and chest x-ray are normal, eliminating infection and heart failure. Assess history: The client ran out of insulin, which directly causes hyperglycemia. Prioritize actions based on condition: Choose interventions that directly treat or assess the effects of high glucose. Check feet: Hyperglycemia causes neuropathy; this is a standard diabetic assessment. Education: The client's history shows a lack of resources and knowledge about managing glucose levels. Select monitoring parameters: Focus on the "downstream" effects of the primary problem. Glucose monitoring: Necessary to evaluate the new insulin dose. Urination: High glucose causes osmotic diuresis; monitoring output assesses for resolution of this symptom. Take home points Hyperglycemia is defined by blood glucose levels above normal ranges and is confirmed as a chronic issue by an HbA1c greater than 7 percent. Diabetic foot assessments are essential for clients with poor glycemic control to detect peripheral neuropathy and prevent ulceration. Osmotic diuresis occurs when blood glucose exceeds the renal threshold of approximately 180 mg/dL, necessitating monitoring of urine output. Social determinants of health, such as financial instability, significantly impact medication adherence and require nursing assessment and referral to social services.
