A patient is receiving total parenteral nutrition (TPN). Which complication should the nurse monitor for most closely during the first hour of administration?
Answer: Hyperglycemia
Hyperglycemia is the most common metabolic complication of TPN and requires close blood glucose monitoring, especially during initiation.
Which sign is a late indicator of increased intracranial pressure?
Answer: Cushing's triad (hypertension, bradycardia, irregular respirations)
Cushing's triad is an ominous late sign of severely elevated ICP indicating brainstem herniation is imminent.
A nurse is caring for a patient post-thyroidectomy. Which assessment finding requires the most immediate intervention?
Answer: Positive Chvostek's sign
A positive Chvostek's sign (facial muscle twitching when tapping the facial nerve) indicates hypocalcemia from accidental parathyroid removal, risking tetany.
Which type of isolation precaution is required for a patient with active pulmonary tuberculosis?
Answer: Airborne precautions
Tuberculosis is transmitted via airborne particles and requires a negative pressure room, N95 respirator, and airborne precautions.
A patient with type 1 diabetes presents with Kussmaul respirations, fruity breath, and blood glucose of 480 mg/dL. Which condition does the nurse suspect?
Answer: Diabetic ketoacidosis
Kussmaul respirations and fruity breath are classic signs of DKA, caused by ketone accumulation in type 1 diabetes.
Which assessment technique is used to detect ascites in a patient with liver failure?
Answer: Shifting dullness on percussion
Shifting dullness on percussion detects ascites because fluid shifts to dependent areas when the patient changes position.
A patient's arterial blood gas shows: pH 7.28, PaCO2 28 mmHg, HCO3 13 mEq/L. How should the nurse interpret this result?
Answer: Metabolic acidosis with respiratory compensation
A low pH with low HCO3 indicates metabolic acidosis; the low PaCO2 reflects respiratory compensation by hyperventilation.
