Chapter 51 Questions
Question 1 of 5
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 Answer: C
Rationale: Lipid pneumonia may occur if the oral mineral oil is accidentally aspirated into the respiratory tract. The other options are incorrect.
Question 2 of 5
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 Answer: C
Rationale: Bulk-forming drugs increase water absorption, which results in greater total volume (bulk) of the intestinal contents. Bulk-forming laxatives tend to produce normal, formed stools. Their action is limited to the gastrointestinal tract, so there are few, if any, systemic effects. However, they need to be taken with liberal amounts of water to prevent esophageal obstruction and/or fecal impaction.
Question 3 of 5
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 Answer: A
Rationale: Taking hypoglycemic drugs with an adsorbent such as bismuth subsalicylate may result in decreased absorption of the hypoglycemic drugs. The other options are incorrect.
Question 4 of 5
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 Answer: D
Rationale: Polyethylene glycol is a very potent laxative that induces total cleansing of the bowel and is most commonly used before diagnostic or surgical bowel procedures. The other options are incorrect.
Question 5 of 5
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 Answer: C
Rationale: Long-term use of laxatives may lead to dependency. Patients need to be taught that daily bowel movements are not necessary for bowel health.
