A nurse is teaching a newly licensed nurse about adverse effects of medications.
The nurse should include that which of the following medications can cause constipation?
Anticholinergics/antispasmodics.
Opioid narcotics.
Iron supplements.
Magnesium-containing antacids.
Correct Answer : A,B,C
Choice A rationale
Anticholinergics/antispasmodics can cause constipation by reducing the muscle contractions of the gastrointestinal tract, leading to slower movement of contents and resulting in constipation.
Choice B rationale
Opioid narcotics cause constipation by binding to opioid receptors in the gastrointestinal tract, which decreases intestinal motility and inhibits the secretion of fluids, leading to hard and dry stools.
Choice C rationale
Iron supplements can cause constipation as a common side effect due to their effect on the gastrointestinal tract. They can make stools harder and more difficult to pass.
Choice D rationale
Magnesium-containing antacids typically do not cause constipation. In fact, they are more likely to have a laxative effect due to the presence of magnesium, which can increase water in the intestines and soften stools.

Correct Answer is D
Explanation
Choice D rationale
Intravenous (IV) administration has the fastest rate of absorption because the medication is delivered directly into the bloodstream, bypassing the absorption barriers of the digestive
system or muscle tissue. This ensures rapid onset of action.
Choice A rationale
Enteral administration involves the gastrointestinal tract, including oral and feeding tube methods. Absorption is slower as the medication passes through the digestive system before
entering the bloodstream.
Choice B rationale
Intramuscular (IM) administration involves injecting the medication into muscle tissue, where it is absorbed into the bloodstream. Absorption is quicker than enteral routes but slower
compared to IV administration.
Choice C rationale
Topical administration involves applying medication to the skin or mucous membranes. Absorption is generally slower and is intended for local or systemic effects, depending on the medication.
Correct Answer is B
Explanation
Choice A rationale
White rice is a low-fiber food that is usually recommended to help manage diarrhea, as it can help firm up stools.
Choice B rationale
Caffeinated beverages can increase intestinal motility and secretions, leading to diarrhea. They can also be irritating to the gastrointestinal tract.
Choice C rationale
Low-fiber cereals are less likely to cause diarrhea and are often recommended for those with diarrhea because they are easy to digest.
Choice D rationale
Ripe bananas are low in fiber and high in potassium, which is beneficial for those with diarrhea as they help in firming up the stool.
