Which instruction is most appropriate for a client who is receiving a bulk-forming laxative?

Take with at least two full glasses of water

Increase food intake

Decrease water intake

Exercise more than three times a week

Answer and Explanation

The Correct Answer is A

A. Take with at least two full glasses of water : This is the correct answer. Bulk-forming laxatives require adequate fluid intake to swell in the intestine, forming a gel-like substance that aids in stool formation and bowel movement. Without sufficient water, they can cause or worsen constipation.
B. Increase food intake: This is not specific to the administration of bulk-forming laxatives and may not directly address the proper use of the medication.
C. Decrease water intake: This is incorrect and potentially harmful, as inadequate water intake can lead to impaction or obstruction when taking bulk-forming laxatives.
D. Exercise more than three times a week: While regular exercise is beneficial for bowel health, this instruction does not directly relate to the specific needs of taking bulk-forming laxatives.

Correct Answer is D

Explanation

A. The amount of blood pumped by the heart through the circulatory system in 1 minute. This statement describes cardiac output, which is unrelated to digestion. It refers to the volume of blood the heart pumps per minute.
B. Neutralization by use of bicarbonate from pancreatic and biliary secretions. This statement accurately reflects a component of digestion. Bicarbonate from the pancreas and biliary secretions neutralizes stomach acid in the small intestine, creating an optimal pH for digestive enzymes.
C. Smooth muscle movement of the GI tract by way of contractions. This statement describes peristalsis, the wave-like contractions that move food through the digestive tract. While peristalsis is essential for digestion, it does not explain the process of breaking down food into absorbable molecules.
D. It is the process when food is broken down into molecules that can be absorbed. This statement accurately defines digestion. It describes the process by which food is broken down into smaller molecules that can be absorbed into the bloodstream and used by the body.

A. Stimulates secretions B. Suppresses the urge to cough C. Reduces inflammation D. Dries mucous membranes

Correct Answer is A

Explanation

A. Stimulates secretions: Expectorants work by thinning and loosening mucus in the airways, making it easier to cough up and clear out. This mechanism helps to reduce cough by facilitating the removal of mucus.
B. Suppresses the urge to cough: Cough suppressants, or antitussives, work by suppressing the cough reflex, not by stimulating secretions. This choice describes a different type of medication used for dry, unproductive coughs.
C. Reduces inflammation: Anti-inflammatory medications reduce inflammation, but they do not specifically target mucus production or the cough reflex. Expectorants do not primarily work by reducing inflammation.
D. Dries mucous membranes: Drying mucous membranes would typically be the action of antihistamines or decongestants, which are not the primary mechanism of action for expectorants. Expectorants aim to keep mucus hydrated to facilitate its removal.
