The nurse administers loperamide to a client. The nurse expects to decrease the client's number and liquidity of stool by what mechanism?

decreasing intestinal motility

absorbing toxins

binding with fecal material to increase bulk

blocking the chemoreceptor trigger zone (CTZ)

Answer and Explanation

The Correct Answer is A

A. decreasing intestinal motility: Loperamide is an opioid-receptor agonist that works primarily by slowing peristalsis in the intestines. This prolongs transit time, allowing more water and electrolytes to be absorbed, which leads to firmer stools and reduced frequency.

B. absorbing toxins: Loperamide does not have the ability to bind or neutralize intestinal toxins. Medications such as activated charcoal or specific antibiotics are used in cases where toxin absorption or elimination is necessary, not loperamide.

C. binding with fecal material to increase bulk: Bulk-forming agents like psyllium work by increasing stool mass to stimulate bowel movement. Loperamide has the opposite effect, reducing motility rather than promoting it, and does not act by bulking the stool.

D. blocking the chemoreceptor trigger zone (CTZ): The CTZ is involved in nausea and vomiting, not diarrhea. Drugs that block the CTZ, such as ondansetron or metoclopramide, are used as antiemetics, not antidiarrheals like loperamide.

Correct Answer is B

Explanation

A. decrease the amount of wastes excreted: Laxatives do not reduce waste excretion; rather, they stimulate bowel movements to promote elimination. Their purpose is to relieve constipation by encouraging the evacuation of feces, not to decrease waste output.

B. improve and speed up the passage of the intestinal contents: Laxatives act by softening stool, stimulating peristalsis, or increasing water in the bowel to ease and hasten stool passage. This supports their use in treating constipation or preparing the bowel for procedures.

C. increase the digestion of stomach contents: Laxatives do not influence gastric digestion. Digestion involves enzymatic breakdown in the stomach and small intestine, while laxatives act primarily in the colon to facilitate stool movement and excretion.

D. increase absorption of the contents of the intestines: Many laxatives actually decrease absorption by accelerating transit through the intestines. The faster movement leaves less time for water and nutrients to be absorbed, often leading to looser stools.

A. The client's random blood glucose is 120 mg/dL (6.7 mmol/L). B. The client's creatinine clearance of 1.75 mL/s/m2 is within reference ranges. C. The client's glycosylated hemoglobin (HbA1c) level is 6.1% (0.06). D. The client's fasting blood glucose level is 80 mg/dL (4.4 mmol/L).

Correct Answer is C

Explanation

A. The client's random blood glucose is 120 mg/dL (6.7 mmol/L): A normal random glucose is encouraging, but it reflects only a momentary snapshot. Glucose levels can fluctuate throughout the day, so this test does not provide a reliable indicator of long-term diabetes control.

B. The client's creatinine clearance of 1.75 mL/s/m² is within reference ranges: While renal function is important in diabetic clients, especially due to the risk of nephropathy, creatinine clearance does not assess how well blood glucose levels are being managed specifically.

C. The client's glycosylated hemoglobin (HbA1c) level is 6.1% (0.06): HbA1c reflects the client’s average blood glucose control over the past 2 to 3 months. A value of 6.1% suggests effective long-term management of type 1 diabetes and is the best indicator of glucose control.

D. The client's fasting blood glucose level is 80 mg/dL (4.4 mmol/L): This is a normal fasting value and suggests good short-term control. However, like random glucose, it only represents glucose levels at one point in time and does not assess cumulative management.
