Report black tarry stools, coffee-ground emesis, or worsening pain that may signal ongoing GI bleed.

Test yourself first: 5 questions
Question 1 of 5
A client is prescribed omeprazole for gastroesophageal reflux disease. When should the nurse instruct the client to take this medication for best effect?
Answer: B. Proton pump inhibitors such as omeprazole are most effective when taken 30 to 60 minutes before the first meal of the day, because they work best on actively secreting proton pumps that are stimulated by food. Taking it at bedtime, with antacids, or only when symptoms occur reduces effectiveness. Antacids should be separated from many drugs but timing the PPI before breakfast is the priority teaching point.
Question 2 of 5
A nurse programs an infusion pump to deliver 1000 mL of normal saline over 8 hours. What rate in milliliters per hour should the nurse set?
Answer: C. An electronic pump is programmed in mL/hr: 1000 mL / 8 hr = 125 mL/hr. The drop factor is not needed when a volumetric pump controls the rate.
Question 3 of 5
A medication is supplied as 1 g in 250 mL. The order is to infuse 500 mg over 30 minutes. How many milliliters per hour should the nurse set on the pump?
Answer: B. 500 mg is half of 1 g, so it is contained in 125 mL. To give 125 mL in 30 minutes the hourly rate is 250 mL/hr. Convert the dose to its volume first, then scale to one hour.
Question 4 of 5
A nurse is calculating an IV infusion and obtains a rate of 250 mL/hr to deliver a routine maintenance fluid over a full shift. Before programming the pump, what should the nurse do?
Answer: B. An unusually high maintenance rate is a red flag. The nurse should recheck the calculation and verify the order rather than program a potentially harmful rate. Independently lowering the rate, ignoring the discrepancy, or proceeding without verification are unsafe. Stopping to double-check abnormal results is core medication-safety practice.
Question 5 of 5
A client takes a proton pump inhibitor (PPI, e.g., omeprazole). The nurse teaches to:
Answer: B. Take PPIs before the first meal of the day for best acid suppression, use for the prescribed duration, and report long-term concerns (B12, magnesium, fracture risk) — not to take it 'as needed' for instant relief like an antacid.
Keep the streak going with more questions like these, each with a full rationale.
What is proton pump inhibitors?
They are used for GERD, peptic ulcer disease, H. pylori eradication, and stress-ulcer prophylaxis. Memory aid: the -prazole suffix (omeprazole, pantoprazole, esomeprazole, lansoprazole).
Key points to remember
- Suppress gastric acid more completely than H2 blockers by shutting down the final common step of acid secretion.
- Most effective when taken 30 to 60 minutes before the first meal of the day.
- Delayed-release capsule contents may be sprinkled on applesauce but must not be crushed or chewed.
- Long-term use is linked to low magnesium, low calcium absorption with osteoporosis/fractures, vitamin B12 deficiency, and increased C. difficile and pneumonia risk.
- Omeprazole and esomeprazole can reduce activation of clopidogrel, lowering its antiplatelet effect.
- IV pantoprazole is commonly used for active GI bleeding and stress-ulcer prophylaxis in critically ill patients.
Signs & symptoms
- Long-term: ↓ Mg, ↓ B12, ↓ Ca
- ↑ fracture & C. diff risk
Nursing priorities
- Administer 30 to 60 minutes before breakfast for maximum effect.
- Assess for relief of heartburn/epigastric pain and monitor stool for occult or frank blood.
- Monitor magnesium, calcium, and B12 levels with prolonged therapy.
- Review the medication list for clopidogrel and other interacting drugs before giving omeprazole.
- Reinforce that PPIs are for short-term courses unless a provider directs long-term use.
Labs & values
Patient teaching
- Take before eating, not after, for best acid control.
- Do not stop abruptly after long-term use; taper as directed to avoid rebound acid hypersecretion.
- Avoid alcohol, NSAIDs, caffeine, and smoking, which worsen acid-related disease.
- Tell your provider if symptoms persist beyond 14 days of over-the-counter use.
Red flags: report now
- Report black tarry stools, coffee-ground emesis, or worsening pain that may signal ongoing GI bleed.
- Report muscle cramps, tremors, palpitations, or seizures that may indicate hypomagnesemia.
- Never crush or chew delayed-release/enteric-coated forms.
- Report new persistent watery diarrhea, which may signal C. difficile infection.
