A nurse is teaching a client about foods and beverages that can cause diarrhea.
Which of the following should the nurse include in the teaching?
White rice.
Caffeinated beverages.
Low-fiber cereal.
Ripe bananas.
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A rationale
Placing the client into a right lateral position is not the standard position for administering an enema. The left lateral (Sims') position is commonly used as it facilitates the flow of the
solution into the colon.
Choice B rationale
Warming the enema solution to room temperature helps ensure the client's comfort and can prevent cramping and discomfort. Cold solutions can cause discomfort and cramping,
making the procedure less tolerable for the client.
Choice C rationale
Sterile technique is not required for administering an enema. Clean technique is generally sufficient unless otherwise indicated by the client’s condition or specific medical orders.
Choice D rationale
Lubricating the tubing is essential to ensure smooth insertion and prevent trauma to the rectal mucosa, but an oil-based lubricant is not typically used as it can interfere with the
absorption of the enema solution. Water-soluble lubricants are preferred.
Correct Answer is C
Explanation
Choice A rationale
Toxic levels refer to concentrations of a medication that are high enough to cause harmful effects or poisoning. This is not related to the lowest serum concentration.
Choice B rationale
Peak levels are the highest concentration of a medication in the bloodstream after administration. This occurs after the drug is absorbed and distributed.
Choice C rationale
Trough levels occur when the medication is at its lowest concentration in the bloodstream, typically just before the next dose is due. Monitoring trough levels helps ensure therapeutic effectiveness while avoiding toxicity.
Choice D rationale
Half-life refers to the time it takes for the concentration of a drug in the bloodstream to decrease by half. It is not directly related to the lowest serum concentration at a specific point in time.
