week 10 Flashcards
The nurse will teach patients that antacids are effective in the treatment of hyperacidity based on what mechanism of action?
a. Decreases gastric pH
b. Neutralizes gastric acid
c. decrease duodenal pH
neutralizies gastric acid
The nurse will monitor a patient taking an aluminum-containing antacid, such as aluminum hydroxide, for what adverse effect?
a. Diarrhea
b. Constipation
c. fluid retention
d. GI upset
constipation
For a patient diagnosed with chronic renal failure, the nurse will question a prescription for what type of antacid?
a. Calcium-containing antacids
b. Sodium-containing antacids
c. Aluminum-containing antacids
d. Magnesium-containing antacids
Magnesium-containing antacids
What condition will the nurse monitor for with a patient using sodium bicarbonate to treat gastric hyperacidity?
a. Hyperkalemia
b. Hypercalcemia
c. Metabolic acidosis
d. Metabolic alkalosis
metabolic alkalosis
What nursing diagnosis is appropriate for a patient receiving famotidine?
a. Risk for infection related to immunosuppression
b. Risk for injury related to thrombocytopenia
c. Impaired urinary elimination related to retention
d. Ineffective peripheral tissue perfusion related to hypertension
Risk for injury related to thrombocytopenia
What is the mechanism of action for famotidine?
a. A decrease in stomach pH, reducing stomach acidity
b. Competes with histamine for binding sites on the parietal cells
c. Forms a protective coating against gastric acid, pepsin, and bile salts
d. Irreversibly binds to the hydrogen–potassium–adenosine triphosphatase (ATPase) pump
Competes with histamine for binding sites on the parietal cells
What patient statement demonstrates understanding of teaching by the nurse regarding the use of histamine2-receptor antagonists?
a. “I should increase bulk and fluids in my diet to prevent constipation.”
b. “Because I am taking this medication, it is OK for me to eat spicy foods.”
c “Smoking decreases the effects of this medication, so I should look into cessation programs.”
“I should take this medication 1 hour after each meal to maximally decrease gastric acidity
“Smoking decreases the effects of this medication, so I should look into cessation programs.”
How will the nurse describe the action of proton pump inhibitors (PPIs)?
a. They compete with histamine for binding sites on the parietal cells.
b. They form a protective barrier that can be thought of as a liquid bandage. Incorrect
c. They irreversibly bind to the hydrogen–potassium–ATPase pump.
d. They help to neutralize acid secretions to promote gastric mucosal defensive mechanisms
They irreversibly bind to the hydrogen–potassium–ATPase pump.
PPIs have the ability to almost inhibit gastric acid secretion totally. Because of this possibility, the use of the medication can lead to what condition?
a. Achlorhydria
b. Diverticulosis
c. Gastric ulcer formation
d. Gastroesophageal reflux disease (GERD)
Achlorhydria
The nurse will question an order for misoprostol in what patient?
a. A 21-year-old man with Zollinger–Ellison syndrome I
b. A 64-year-old man with hypertension
c. A 32-year-old pregnant woman with a urinary tract infection
d. A 45-year-old woman with GERD
A 32-year-old pregnant woman with a urinary tract infection
The nurse would teach a patient prescribed simethicone to avoid what substance?
a. Carbonated beverages
b. Milk and dairy products
c. Over-the-counter (OTC) antacids
Carbonated beverages
