Question 1
Regular
A patient is receiving an aluminum-containing antacid. The nurse will inform the patient to watch for which possible adverse effect?
Correct!
Incorrect
The correct answer is: B
Rationale
Patients using aluminum-containing antacids should be vigilant for constipation. Aluminum compounds can cause slowed gastrointestinal motility, leading to infrequent bowel movements and discomfort, making this an important side effect to monitor.
A: Diarrhea Aluminum-based antacids typically do not induce diarrhea; instead, they often result in the opposite effect due to their constipating properties, which counters this adverse reaction.
C: Nausea The use of aluminum-containing antacids is not commonly associated with nausea, as their primary function is to neutralize stomach acid, which usually alleviates discomfort rather than provoking it.
D: Abdominal cramping While abdominal cramping can occur for various reasons, it is not a typical adverse effect linked to aluminum antacids, whose primary concern is constipation rather than cramping.

Question 2
Regular
When reviewing the health history of a patient who will be receiving antacids, the nurse recalls that antacids containing magnesium need to be used cautiously in patients with which condition?
Correct!
Incorrect
The correct answer is: B
Rationale
Antacids containing magnesium need to be used cautiously in patients with renal failure. This is due to impaired kidney function, which can lead to magnesium accumulation and potential toxicity.
A: Peptic ulcer disease Antacids can help alleviate symptoms of peptic ulcer disease, making their use appropriate in managing this condition, rather than a cause for caution.
C: Hypertension Antacids generally do not have a significant impact on blood pressure, allowing their use in patients with hypertension without considerable risk.
D: Heart failure Heart failure does not specifically contraindicate the use of magnesium-containing antacids, as the primary concern lies with renal function rather than cardiac status.

Question 3
Regular
The nurse is reviewing the medication orders for a patient who will be taking an H2 antagonist. Which drug may have an interaction if taken along with the H2 antagonist?
Correct!
Incorrect
The correct answer is: D
Rationale
Ketoconazole may have an interaction if taken along with the H2 antagonist. H2 antagonists reduce stomach acid, which is essential for the absorption of ketoconazole, potentially leading to decreased effectiveness of the antifungal medication.
A: Ibuprofen Non-steroidal anti-inflammatory drugs like ibuprofen do not significantly interact with H2 antagonists, as their mechanisms of action do not rely on stomach acidity for effectiveness.
B: Cimetidine Cimetidine is itself an H2 antagonist, making it redundant in this context and not presenting any interaction concern when paired with another H2 antagonist.
C: Tetracycline Tetracycline does not have a notable interaction with H2 antagonists; its absorption may be affected by other factors, but H2 antagonists do not significantly impact its effectiveness.
Correct Answer: D

Question 4
Regular
A patient who has been taking cimetidine for hyperacidity calls the clinic to say that the medication has not been effective. The nurse reviews his history and notes that which factor may be influencing the effectiveness of this drug?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Smoking two packs of cigarettes a day can significantly impact the metabolism of cimetidine, reducing its effectiveness. Cigarette smoke contains substances that induce liver enzymes, which can decrease drug concentration in the body, leading to inadequate therapeutic effects.
A: Taking cimetidine with meals may actually enhance absorption. Food does not significantly reduce its effectiveness, and this timing can help optimize the drug's therapeutic impact.
C: Drinking a glass of water with each dose aids in swallowing and absorption but does not influence the medication's effectiveness. Water does not interact negatively with cimetidine.
D: Taking an antacid 3 hours after cimetidine does not affect its absorption significantly. However, if taken simultaneously, antacids can interfere with cimetidine's efficacy, making this timing less problematic.
Correct Answer: B

Question 5
Regular
A patient is taking omeprazole for the treatment of gastroesophageal reflux disease (GERD). The nurse will include which statement in the teaching plan about this medication?
Correct!
Incorrect
The correct answer is: D
Rationale
D: The entire capsule must be taken whole, not crushed, chewed, or opened. This is essential for omeprazole to maintain its protective coating and ensure proper release and absorption in the stomach.
A: Take this medication once a day after breakfast. Although omeprazole is often taken once daily, timing can vary; it should ideally be consumed before meals for optimal efficacy.
B: You will be on this medication for only 2 weeks for treatment of the reflux disease. Long-term treatment may be necessary for some patients, as GERD symptoms can persist beyond two weeks.
C: The medication may be dissolved in a liquid for better absorption. Omeprazole must remain intact in its capsule form to ensure its effectiveness, as altering it compromises its protective properties.
Correct Answer: D

Question 6
Regular
A patient has excessive and painful gas. The nurse checks the patient's medication orders and prepares to administer which drug for this problem?
Correct!
Incorrect
The correct answer is: D
Rationale
Simethicone. This medication effectively reduces gas and bloating by decreasing the surface tension of gas bubbles, allowing them to coalesce and be eliminated more easily, providing relief from discomfort.
A: Famotidine. This drug primarily treats acid-related stomach issues and does not specifically address gas or bloating, making it unsuitable for relieving excessive and painful gas symptoms.
B: Aluminum hydroxide and magnesium hydroxide. These compounds act as antacids to neutralize stomach acid but do not target the underlying causes of gas accumulation or its associated pain.
C: Calcium carbonate. While it serves as an antacid and can relieve heartburn, it does not have a direct effect on alleviating gas-related discomfort, making it less effective for this issue.

Question 7
Regular
A 75-year-old woman comes into the clinic and states she has had muscle twitching, nausea, and headache. She tells the nurse that she has been taking sodium bicarbonate five or six times a day for the past 3 weeks. The nurse will assess for which potential problem that may occur with overuse of sodium bicarbonate?
Correct!
Incorrect
The correct answer is: C
Rationale
Muscle twitching, nausea, and headache suggest potential electrolyte imbalances. Overuse of sodium bicarbonate can lead to metabolic alkalosis, characterized by increased blood pH and bicarbonate levels, resulting in these symptoms.
A: Constipation Excessive sodium bicarbonate intake can actually lead to diarrhea rather than constipation due to its alkalizing effect on the digestive tract and alterations in gastric motility.
B: Metabolic acidosis Sodium bicarbonate is used to treat acidosis, so overuse would not produce this condition. Instead, it raises blood pH, counteracting acidosis rather than contributing to it.
D: Excessive gastric mucus Sodium bicarbonate does not lead to increased gastric mucus production. Its primary role is to neutralize stomach acid, which does not alter mucus secretion in the stomach.

Question 8
Regular
A patient will be taking a 2-week course of combination therapy with omeprazole and another drug for a peptic ulcer caused by Helicobacter pylori. The nurse expects a drug from which class to be ordered with the omeprazole?
Correct!
Incorrect
The correct answer is: A
Rationale
Antibiotic. Combination therapy for a peptic ulcer caused by Helicobacter pylori typically includes an antibiotic alongside a proton pump inhibitor like omeprazole to effectively eradicate the bacteria and promote healing.
B: Nonsteroidal anti-inflammatory drug. This class can exacerbate peptic ulcers by increasing gastric irritation and should not be combined with omeprazole for this specific condition.
C: Antacid. Antacids provide temporary relief from symptoms but do not address the underlying infection caused by Helicobacter pylori, making them unsuitable for this treatment regimen.
D: Antiemetic. While useful for nausea, antiemetics do not target the Helicobacter pylori infection or contribute to the healing of peptic ulcers, making them irrelevant in this context.

Question 9
Regular
A patient is asking advice about which over-the-counter antacid is considered the most safe to use for heartburn. The nurse explains that the reason that calcium antacids are not used as frequently as other antacids is for which of these reasons?
Correct!
Incorrect
The correct answer is: A
Rationale
Calcium antacids are less frequently used due to their potential to lead to kidney stones. This risk arises from the calcium content, which can contribute to the formation of these painful calculi in susceptible individuals.
B: They cause decreased gastric acid production. Calcium antacids do not primarily function by reducing gastric acid levels, but instead neutralize existing acid, thus not significantly impacting acid production.
C: They cause severe diarrhea. Calcium antacids are more associated with constipation rather than diarrhea, which is a common side effect of magnesium-based antacids, not calcium-based ones.
D: Their use may result in fluid retention and edema. Fluid retention and edema are typically linked to sodium-based antacids, not calcium antacids, which do not have this specific side effect profile.

Question 10
Regular
At 0900, the nurse is about to give morning medications, and the patient has asked for a dose of antacid for severe heartburn. Which schedule for the antacid and medications is correct?
Correct!
Incorrect
The correct answer is: C
Rationale
At 0900, the antacid should be administered at 1900, allowing the medications to be given at 0900. This schedule prevents interactions between the antacid and medications, ensuring optimal absorption.
A: Give both the antacid and medications at 0900. This approach risks reducing the efficacy of the medications due to potential interactions with the antacid, compromising treatment effectiveness.
B: Give the antacid at 0900, and then the medications at 0900. Administering both at the same time can lead to interference in medication absorption, undermining the therapeutic outcomes intended.
D: Give the medications at 0900, and then the antacid at 0915. While this separates their administration, the antacid should be given later to avoid diminishing the effects of the medications taken earlier.

Question 11
Regular
During an admission assessment, the patient tells the nurse that he has been self-treating his heartburn for 1 year with over-the-counter Prilosec OTC (omeprazole, a proton pump inhibitor). The nurse is aware that this self-treatment may have which result?
Correct!
Incorrect
The correct answer is: D
Rationale
Self-treatment with Prilosec OTC may mask symptoms of serious underlying diseases. Prolonged use of proton pump inhibitors can lead to reduced gastric acidity, obscuring critical indications of conditions such as gastroesophageal reflux disease or gastric cancer.
A: No serious consequences Over-the-counter medications can lead to overlooked health issues, making this assumption misleading as serious conditions may develop undetected.
B: Prevention of more serious problems, such as an ulcer Prolonged use of proton pump inhibitors can mask symptoms rather than prevent issues, potentially allowing conditions to worsen unnoticed.
C: Chronic constipation Chronic constipation is not a known direct effect of proton pump inhibitors, as they primarily impact gastric acid production rather than bowel function.

Question 12
Regular
An older adult patient had gastric surgery due to a gastrointestinal bleed 3 days ago, and he has been stable since the surgery. This evening, his daughter tells the nurse, 'He seems to be more confused this afternoon. He's never been like this.' What could be the problem? The nurse reviews the patient's medication record and suspects that which drug could be the cause of the patient's confusion?
Correct!
Incorrect
The correct answer is: A
Rationale
Cimetidine. This medication is known to cross the blood-brain barrier and can lead to confusion, especially in older adults, due to its potential central nervous system side effects.
B: Pantoprazole. This proton pump inhibitor primarily acts in the gastrointestinal tract and is less likely to cause neurological symptoms such as confusion.
C: Clarithromycin. While this antibiotic can have side effects, confusion is not commonly associated with its use in older adults, making it an unlikely cause in this scenario.
D: Sucralfate. This medication acts locally in the gastrointestinal tract to protect the mucosa and does not typically cause central nervous system effects, thus unlikely to lead to confusion.

Question 13
Regular
The nurse is teaching a patient who will be taking a proton pump inhibitor as long-term therapy about potential adverse effects. Which statement is correct?
Correct!
Incorrect
The correct answer is: D
Rationale
Long-term use of these drugs may contribute to osteoporosis. This statement is accurate as proton pump inhibitors can interfere with calcium absorption, leading to decreased bone density and increasing fracture risk over time.
A: Proton pump inhibitors can cause diarrhea. While gastrointestinal side effects may occur, diarrhea is not a primary concern associated with long-term use of these medications.
B: These drugs can cause nausea and anorexia. Although some patients may experience these symptoms, they are not common or significant adverse effects of long-term proton pump inhibitor therapy.
C: Proton pump inhibitors cause drowsiness. Drowsiness is not a typical side effect linked to proton pump inhibitors, making this statement misleading regarding the potential effects of these medications.
Correct Answer: D

Question 14
Regular
A patient in the intensive care unit has a nasogastric tube and is also receiving a proton pump inhibitor (PPI). The nurse recognizes that the purpose of the PPI is which effect?
Correct!
Incorrect
The correct answer is: A
Rationale
Prevent stress ulcers.
Proton pump inhibitors (PPIs) are utilized in critical care settings primarily to decrease gastric acid secretion, thereby safeguarding the gastric mucosa from the detrimental effects of stress-induced ulcers, which can develop in patients under severe physiological stress.
B: Reduce bacteria levels in the stomach. PPIs primarily focus on acid suppression rather than directly targeting bacterial populations, making this option not applicable in the context of ulcer prevention.
C: Reduce gastric gas formation (flatulence). The action of PPIs does not address gas production in the gastrointestinal tract; their main role is to inhibit acid secretion, unrelated to flatulence issues.
D: Promote gastric motility. PPIs do not influence gastric motility; their function centers on reducing acid output, which does not enhance the movement of the stomach contents.

Question 16
Calculation(ans only)
A patient will be receiving pantoprazole, 20 mg IV daily every morning. The medication, once reconstituted, has a strength of 40 mg/10 mL. Identify how many milliliters the nurse will draw up for this dose.
Correct!
Incorrect
The correct answer is: 5 ML
Rationale
5 mL
To administer a 20 mg dose of pantoprazole, the nurse calculates the volume needed from the reconstituted solution of 40 mg/10 mL. This results in a calculation of 5 mL to achieve the desired dosage accurately.
A: 10 mL
Drawing up 10 mL corresponds to a 40 mg dose, which exceeds the prescribed 20 mg dosage, thereby providing an insufficient therapeutic effect for the patient’s needs.
B: 2.5 mL
Using 2.5 mL would provide only 10 mg of pantoprazole, falling short of the required 20 mg dose and potentially compromising the patient's treatment effectiveness.
C: 1 mL
1 mL delivers only 4 mg of pantoprazole, significantly below the necessary 20 mg, rendering it inadequate to meet the therapeutic requirement for the patient.
