A client receives a prescription for vancomycin 500 mg IV every 8 hours. The medication is provided in "500 mg per 100 mL of dextrose 5% in water." To administer the medication over an hour, the nurse should set the infusion pump to deliver how many mL/hr? (Enter numerical value only.)
The Correct Answer is ["100"]
Vancomycin dosage: 500 mg
Concentration of vancomycin solution: 500 mg per 100 mL
Total volume of solution for each dose: 100 mL (since the concentration is 500 mg per 100 mL) To administer 500 mg of vancomycin, we need 100 mL of the solution.
To administer the medication over 1 hour, we need to deliver the entire 100 mL over 1 hour. Therefore, the infusion rate (in mL/hr) would be 100 mL/hr.

Correct Answer is A
Explanation
A Hematemesis refers to vomiting blood, which can occur when esophageal varices rupture and bleed into the gastrointestinal tract. It is a hallmark sign of upper gastrointestinal bleeding and requires immediate medical attention. Monitoring for hematemesis allows for early detection of variceal bleeding and prompt intervention to prevent further complications.
B Brown, foamy urine may indicate the presence of blood or protein in the urine, which can occur in various kidney and urinary tract disorders.
C Clay-colored stool may indicate a lack of bile in the stool, which can occur in conditions affecting the liver or bile ducts, such as obstructive jaundice.
D Anorexia, or loss of appetite, is a common symptom in clients with chronic liver disease, including cirrhosis. However, while anorexia may impact nutritional status and overall health, it is not directly related to the complications of esophageal varices.

Yellow sclera is a concerning sign that should be reported promptly to the healthcare provider as it indicates potential bile duct obstruction and impaired liver function
