Question 1
Regular
The nurse is giving oral mineral oil as an ordered laxative dose. The nurse will take measures to prevent which potential problem that may occur with mineral oil?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Lipid pneumonia. Mineral oil can enter the lungs if aspirated, leading to lipid pneumonia, a serious condition characterized by inflammation and infection in the lungs due to fat accumulation.
A: Fecal impaction. Mineral oil acts as a lubricant laxative, helping to soften stools and prevent fecal impaction, making this option irrelevant in the context of mineral oil use.
B: Electrolyte imbalances. While laxatives can affect electrolytes, mineral oil primarily lubricates, and does not typically disrupt electrolyte balance, which is more associated with stimulant laxatives.
D: Esophageal blockage. Mineral oil is intended to facilitate easier stool passage and does not create blockages in the esophagus; rather, it helps prevent complications related to hard stool.

Question 2
Regular
When administering a bulk-forming laxative, the nurse instructs the patient to drink the medication mixed in a full 8-ounce glass of water. Which statement best explains the rationale for this instruction?
Correct!
Incorrect
The correct answer is: C
Rationale
C: These laxatives may cause esophageal obstruction if taken with insufficient water. Adequate hydration is crucial as it allows the bulk-forming laxative to expand and function effectively, preventing potential complications like obstruction.
A: The water acts to stimulate bowel movements. While hydration is vital, the primary action of bulk-forming laxatives relies on their ability to absorb water and increase stool bulk, not just stimulation.
B: The water will help to reduce the bulk of the intestinal contents. This statement misrepresents the function; water actually increases the bulk of the intestinal contents, aiding in easier passage.
D: The water acts as a lubricant to produce bowel movements. Though lubrication can aid bowel movements, bulk-forming laxatives primarily work by expanding with water, not by providing lubrication.

Question 3
Regular
A patient will be taking bismuth subsalicylate to control diarrhea. When reviewing the patient's other ordered medications, the nurse recognizes that which medication or medication class will interact significantly with this drug?
Correct!
Incorrect
The correct answer is: A
Rationale
Hypoglycemic drugs will interact significantly with bismuth subsalicylate. This medication can reduce the absorption of hypoglycemic agents, potentially leading to altered blood glucose levels and ineffective management of diabetes in patients taking these medications.
B: Antibiotics may have some interactions, but they typically do not affect the absorption or efficacy of bismuth subsalicylate as significantly as hypoglycemic drugs do.
C: Acetaminophen does not interact notably with bismuth subsalicylate, allowing both medications to work effectively without significantly altering each other's metabolism or therapeutic effects.
D: Antidepressants generally do not pose a significant interaction risk with bismuth subsalicylate, and their effectiveness remains largely intact without major concerns when taken together.

Question 4
Regular
A patient is about to undergo a diagnostic bowel procedure. The nurse expects which drug to be used to induce total cleansing of the bowel?
Correct!
Incorrect
The correct answer is: D
Rationale
Polyethylene glycol 3350 is the drug expected to induce total cleansing of the bowel. This osmotic agent effectively draws water into the intestines, promoting thorough elimination of fecal matter, which is essential for clear visualization during diagnostic procedures.
A: Docusate sodium A stool softener, docusate sodium primarily aids in preventing constipation rather than inducing bowel cleansing, making it unsuitable for procedures requiring complete bowel clearance.
B: Lactulose While lactulose facilitates bowel movements by increasing osmotic pressure, it does not achieve the total cleansing necessary for diagnostic bowel procedures, rendering it ineffective for this purpose.
C: Mineral oil Although mineral oil can lubricate the intestines, it does not provide the comprehensive cleansing effect needed for a diagnostic bowel procedure, limiting its utility in this context.

Question 5
Regular
While recovering from surgery, an elderly woman started taking a stimulant laxative, senna, to relieve constipation caused by the pain medications. Two weeks later, at her follow-up appointment, she tells the nurse that she likes how 'regular her bowel movements are now that she is taking the laxative.' Which teaching principle is appropriate for this patient?
Correct!
Incorrect
The correct answer is: C
Rationale
Long-term use of laxatives often results in decreased bowel tone and may lead to dependency. This principle highlights the potential risks associated with prolonged stimulant laxative use, which may ultimately exacerbate bowel issues rather than alleviate them.
A: She needs to be sure to take this medication with plenty of fluids. While hydration is vital, the primary concern here is the potential for laxative dependency.
B: It is important to have a daily bowel movement to promote bowel health. Daily bowel movements can be beneficial, but this doesn't address the risks of long-term laxative use.
D: She needs to switch to glycerin suppositories to continue having daily bowel movements. Switching methods doesn't resolve the issue of laxative dependency and may not be necessary for her situation.

Question 6
Regular
A patient asks the nurse about the difference between diphenoxylate with atropine and the over-the-counter drug loperamide (Imodium). Which response by the nurse is correct?
Correct!
Incorrect
The correct answer is: B
Rationale
Loperamide (Imodium) does not cause physical dependence. This differentiates it from diphenoxylate with atropine (Lomotil), which has the potential for misuse due to its opioid-like effects and can lead to dependence.
A: Lomotil acts faster than Imodium. The onset of action for both medications varies, but Lomotil is often noted for its slower onset compared to Imodium.
C: Lomotil is available in suppository form. Lomotil is primarily offered in oral formulations, whereas other medications may be available as suppositories but not Lomotil.
D: Imodium is a natural antidiarrheal drug. Imodium is a synthetic medication that works by slowing intestinal movement, not derived from natural sources, which limits its classification as a natural remedy.

Question 7
Regular
A patient wants to prevent problems with constipation and asks the nurse for advice about which type of laxative is safe to use for this purpose. Which class of laxative is considered safe to use on a long-term basis?
Correct!
Incorrect
The correct answer is: B
Rationale
Bulk-forming laxatives are considered safe to use on a long-term basis.
These laxatives work by absorbing water and increasing stool bulk, promoting natural bowel movements without causing dependency, making them suitable for ongoing use to prevent constipation.
A: Emollient laxatives facilitate stool passage but do not effectively prevent constipation long-term and may not provide adequate bulk for regular bowel movements.
C: Hyperosmotic laxatives draw water into the bowel, offering relief but can lead to dependency if used continually, making them unsuitable for long-term management.
D: Stimulant laxatives trigger bowel contractions and may cause reliance on their action, thus not recommended for chronic use due to potential adverse effects on bowel health.

Question 8
Regular
When administering mineral oil, the nurse recognizes that it can interfere with the absorption of which substance?
Correct!
Incorrect
The correct answer is: A
Rationale
Fat-soluble vitamins. Mineral oil can hinder the absorption of fat-soluble vitamins such as A, D, E, and K, as it can bind to these vitamins and prevent their uptake in the intestines.
B: Water-soluble vitamins. These vitamins, such as B and C, are absorbed differently and are not affected by mineral oil, which primarily interacts with fat-soluble substances.
C: Minerals. Mineral oil does not significantly impact mineral absorption, as these substances follow different absorption pathways that are not influenced by the presence of oil.
D: Electrolytes. The absorption of electrolytes like sodium and potassium occurs independently of fat-soluble interactions and remains unaffected by the administration of mineral oil.

Question 9
Regular
The nurse is reviewing the mechanism of action of antidiarrheal drugs. Which type of antidiarrheal medication works by decreasing the intestinal muscle tone and peristalsis of the intestines?
Correct!
Incorrect
The correct answer is: B
Rationale
Anticholinergics decrease the intestinal muscle tone and peristalsis of the intestines, effectively slowing down bowel movements and reducing diarrhea symptoms. This mechanism allows for increased absorption of fluids and electrolytes in the intestines.
A: Adsorbents bind to toxins and irritants in the gastrointestinal tract, helping to solidify stool but do not influence muscle tone or peristalsis directly.
C: Probiotics restore the natural balance of gut bacteria, promoting digestive health and regularity, but they do not directly affect intestinal muscle tone or peristalsis.
D: Lubricants facilitate the passage of stool through the intestines by providing a slippery coating, but they do not alter muscle tone or peristalsis in any way.

Question 10
Regular
The nurse is discussing the use of adsorbents such as bismuth subsalicylate with a patient who has diarrhea. The nurse will warn the patient about which possible adverse effects?
Correct!
Incorrect
The correct answer is: A
Rationale
Dark stools and blue gums. Bismuth subsalicylate can cause temporary discoloration of stools and may lead to a bluish tint in the gums due to its bismuth content, which is important for patients to know.
B: Urinary hesitancy. This side effect is not associated with adsorbents like bismuth subsalicylate, which primarily affects the gastrointestinal tract rather than urinary function.
C: Drowsiness and dizziness. These symptoms are typically linked to medications that affect the central nervous system, not to adsorbents that serve to alleviate gastrointestinal distress.
D: Blurred vision and headache. These issues are more commonly associated with other drug classes and do not reflect the side effects typically attributed to bismuth subsalicylate usage.

Question 14
Regular
A patient is severely constipated and needs immediate relief. The nurse knows that which class of laxative will provide the most rapid results?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Magnesium hydroxide provides the most rapid results as it acts quickly to draw water into the intestines, promoting bowel movements. This osmotic effect makes it an effective choice for immediate relief from severe constipation.
A: Bulk-forming laxative, such as psyllium, works gradually by increasing stool bulk and requires time to be effective, making it unsuitable for urgent relief from constipation.
B: Stool softener, such as docusate salts, promotes softer stools but does not stimulate immediate bowel movements; its action is slower and may not provide the necessary quick relief.
D: Magnesium oxide tablets are less effective for immediate constipation relief, as they primarily serve as a supplement rather than a rapid-acting osmotic laxative like magnesium hydroxide.

Question 20
Calculation(ans only)
A patient will be receiving docusate sodium, 120 mg/day PO, divided into 3 doses. Identify how many milligrams will this patient receive per dose.
Correct!
Incorrect
The correct answer is: 40 MG
Rationale
40 mg. Each dose of docusate sodium is calculated by dividing the total daily dosage of 120 mg by the number of doses, which is 3. Thus, 120 mg ÷ 3 = 40 mg per dose, ensuring the patient receives the intended therapeutic amount effectively throughout the day.
A: 20 mg. Dividing 120 mg by 6 doses would lead to 20 mg, which does not align with the prescribed regimen of 3 doses daily.
B: 30 mg. Allocating 30 mg per dose would total only 90 mg daily, failing to meet the prescribed 120 mg dosage essential for the patient's treatment.
C: 50 mg. A dosage of 50 mg per dose would result in a total of 150 mg daily, exceeding the intended daily limit and potentially causing adverse effects.
