Magnesium Sulfate is a(n):
anti-diarrheal
antihistamine
opioid
electrolyte
The Correct Answer is D
A. Anti-diarrheal: Magnesium sulfate is not used to reduce diarrhea; some magnesium salts may actually have a laxative effect. Anti-diarrheal agents act by slowing intestinal motility or absorbing fluid, which is unrelated to magnesium sulfate’s mechanism.
B. Antihistamine: Antihistamines block histamine receptors to reduce allergy symptoms, nausea, or gastric acid secretion. Magnesium sulfate does not interact with histamine pathways and does not treat allergic reactions.
C. Opioid: Opioids act on central nervous system receptors to relieve pain. Magnesium sulfate does not have analgesic or narcotic properties. Its pharmacologic action is unrelated to opioid receptor activity.
D. Electrolyte: Magnesium sulfate provides magnesium ions, an essential electrolyte involved in neuromuscular function, cardiac conduction, and enzymatic reactions. It is used to correct magnesium deficiency, prevent seizures in preeclampsia, and manage certain arrhythmias.

Correct Answer is A
Explanation
A. Patient's room number: Room numbers can change during hospitalization and are not unique identifiers. Using a room number on a medication label could lead to misidentification and medication errors. It is not an appropriate detail for ensuring patient safety.
B. Date and time of preparation: Including the date and time ensures the medication’s stability and helps track expiration for reconstituted drugs. This information is essential for safe administration and adherence to hospital policies.
C. Initials of the nurse who prepared the medication: Documenting the preparer’s initials allows accountability and traceability in case of errors or adverse events. It is a standard requirement for safety and quality assurance.
D. Dose strength of the reconstituted medication: Indicating the concentration or dose of the reconstituted medication is critical to prevent dosing errors. This ensures accurate administration and patient safety.
Correct Answer is D
Explanation
Calculation:
- Identify the total volume and infusion rate
Total Volume: 720 mL
Infusion Rate: 60 mL/hr
- Calculate the time the bag will last
Time (hours) = Total Volume ÷ Infusion Rate
Time = 720 ÷ 60
= 12 hours
