A client who has chronic bronchial asthma has had a mast cell stabilizer prescribed.
What drug would the provider prescribe?

The correct answer is c. The importance of consuming adequate amounts of water.

Rationale for Choice A:

• Statement:The need to monitor for systemic side effects.
• Rationale:It's not accurate to prioritize monitoring for systemic side effects when teaching a patient about psyllium (Metamucil).Psyllium is a bulk-forming laxative that primarily acts within the gastrointestinal tract,and systemic side effects are rare.While it's essential to be aware of potential side effects,focusing on them during initial teaching might cause unnecessary anxiety.

Rationale for Choice B:

• Statement:The need to use the dry form of Metamucil to prevent cramping.
• Rationale:This statement is incorrect.It's generally recommended to mix psyllium with water or another liquid before ingestion.Consuming the dry form can increase the risk of choking and might not adequately hydrate stool.

Rationale for Choice C:

• Statement:The importance of consuming adequate amounts of water.
• Rationale:This is the most crucial information to emphasize when teaching about psyllium.Psyllium works by absorbing water and forming a bulky gel that softens stool and promotes bowel movements.Without sufficient water intake,psyllium can cause constipation to worsen or lead to intestinal obstruction.

Rationale for Choice D:

• Statement:The onset of action of 30 to 60 minutes after administration.
• Rationale:This statement is inaccurate.Psyllium is not a fast-acting laxative.It typically takes 12-72 hours to produce a bowel movement.Informing patients about the expected time frame for results is essential to manage expectations and prevent unnecessary medication overuse.

This is because antiemetics should be given to prevent motion sickness rather than after nausea or vomiting develop. Taking the medication 30 minutes before departing allows enough time for the drug to be absorbed and reach its peak effect.

Choice A is wrong because avoiding eating or drinking for 6 hours before the trip may cause dehydration and low blood sugar, which can worsen nausea and vomiting.

It is better to eat a light meal or snack before the trip and avoid spicy, greasy, or acidic foods.

Choice C is wrong because taking two doses if relief is not achieved may cause overdose and adverse effects.

Antiemetics should be taken as prescribed and not exceeded without consulting a doctor.

Choice D is wrong because increasing fluid intake to prevent urinary retention is not relevant for motion sickness.

Urinary retention is a possible side effect of some antiemetics, such as anticholinergics, but it is not a common problem for most people.

Fluid intake should be moderate and not excessive to avoid stomach distension.
