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 A
Explanation
Rationale:
A. The pH of 7.3 indicates acidemia (normal range 7.35–7.45). The PaCO2 of 50 mm Hg is elevated (normal 35–45 mm Hg), indicating a respiratory cause. This combination is consistent with respiratory acidosis.
B. Respiratory alkalosis would present with a high pH and low PaCO2.
C. Metabolic acidosis would show a low pH and low HCO3-.
D. Metabolic alkalosis would show a high pH and elevated HCO3-.
Correct Answer is C
Explanation
Rationale:
A. Hepatotoxic medications can cause toxic or drug-induced liver injury, but they are not the primary cause of biliary cirrhosis.
B. Excessive alcohol consumption is a major cause of alcoholic cirrhosis, not biliary cirrhosis.
C. Obstruction of the bile duct—whether from gallstones, strictures, or autoimmune disorders—leads to cholestasis. Over time, the retained bile damages liver cells, causing inflammation, fibrosis, and ultimately biliary cirrhosis.
D. Hepatitis C primarily causes viral hepatitis-related cirrhosis, not biliary cirrhosis.
