Exam 2 connection check and chapter review questions

A 58-year-old female with a history of diabetes presents for a routine physical examination. A urinalysis is obtained and evaluated. The results indicate the presence of glucose in the urine. The nurse recognizes that this indicates which of the following? A. Serum glucose of 150 mg/dl B. Serum glucose of 250 mg/dl C. Serum BUN of 12 mg/dl D. Serum BUN of 35 mg/dl - Answer: B Rationale: The presence of glucose in the urine occurs when the renal threshold for glucose (220 mg/dL) is exceeded. Serum BUN does not affect the presence of glucose in the urine. A patient has been admitted to the critical unit with a serum magnesium level of 0.9 mEq/L. The nurse closely monitors the patient for which potential complication of this magnesium level? A. Agitation and restlessness B. Hypotension and bradycardia C. Deep, rapid respirations D. Seizure and ventricular fibrillation - Answer: D Rationale: Patients with low magnesium levels are at risk for seizure and ventricular fibrillation. Agitation and restlessness are seen with hypernatremia. Hypotension and bradycardia are associated with high magnesium levels, and deep, rapid respirations are observed with patients with hypochloremia. A patient is admitted with osteomyelitis and is going to require 3 to 4 weeks of IV antibiotics. Which IVAD is most appropriate for this patient? A. 16-gauge central venous B. 18-gauge over-the-needle IVAD C. 20-gauge midline catheter D. 22-gauge steel-winged device - Answer: B Rationale: Midline catheters are inserted in a peripheral vein in the upper extremities with tips that terminate distal to the shoulder in either the basilica, cephalic or brachial vein. Midlines are appropriate for therapies expected to last between 1 to 4 weeks. Steel-winged
