A nurse is preparing to administer metoclopramide 15 mg PO QID before meals and at bedtime for a client who has GERD. The amount available is metoclopramide 5 mg/5mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["15"]
Rationale:
Desired dose = 15 mg
Available concentration = 5 mg per 5 mL = 1 mg/mL
Volume needed = Desired dose ÷ Concentration = 15 mg ÷ 1 mg/mL = 15 mL
Rounded to nearest whole number = 15 mL
Final Answer: 15 mL

Correct Answer is B
Explanation
Rationale:
A. RBC count is not typically affected by acute pancreatitis unless there is bleeding, which is uncommon.
B. Serum amylase is elevated in acute pancreatitis because pancreatic inflammation leads to the release of digestive enzymes into the bloodstream. Amylase levels usually rise within 6–12 hours of symptom onset and remain elevated for 3–5 days.
C. Calcium levels often decrease in acute pancreatitis due to fat saponification, not increase.
D. Magnesium levels are usually normal or decreased, but elevation is not a typical finding in pancreatitis.
Correct Answer is D
Explanation
Rationale:
A. Serum calcium levels are often decreased in acute pancreatitis due to fat saponification, not increased.
B. Serum lipase is typically elevated, not decreased, in acute pancreatitis, and is often more specific than amylase for pancreatic injury.
C. WBC count usually increases due to inflammation and possible infection; a decreased WBC is not expected.
D. Increased serum amylase is a hallmark laboratory finding in acute pancreatitis. Amylase is released from damaged pancreatic cells into the bloodstream. Levels typically rise within 6–12 hours of onset of symptoms and remain elevated for 3–5 days. Monitoring amylase, along with lipase (which remains elevated longer), helps confirm the diagnosis and assess the severity of pancreatic inflammation. Elevated amylase, in the context of abdominal pain radiating to the back, nausea, and vomiting, supports the provider’s suspicion of acute pancreatitis.
