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 D
Explanation
Rationale:
A. Tachycardia may occur secondary to hypotension, but it is a secondary concern, not the primary pharmacological issue.
B. Paracentesis does not directly affect blood glucose levels.
C. While changes in bowel habits may occur with fluid shifts, they are not the primary concern after paracentesis.
D. Removal of large volumes of ascitic fluid can lead to intravascular volume depletion, resulting in hypotension. Monitoring blood pressure before, during, and after the procedure is essential, and volume replacement may be required to maintain hemodynamic stability.
Correct Answer is B
Explanation
Rationale:
A. The color change of stool is not the purpose of the laxative.
B. A laxative is necessary to help eliminate barium from the gastrointestinal tract, preventing constipation or impaction.
C. The laxative is not used to prevent magnesium absorption; this is unrelated to a barium study.
D. While facilities have protocols, the explanation should focus on patient safety and the purpose of the intervention, not just policy.
