A nurse is reviewing medications for a client who has just been diagnosed with a small bowel obstruction. The nurse should withhold senna prescribed orally based on understanding of which of the following?

Laxatives are contraindicated in clients who have a small bowel obstruction.

An osmotic laxative, such as magnesium citrate, should be substituted in this client

The prescribed medication should be administered via NG route rather than the oral route for this client.

Bulk-forming laxatives such as psyllium should be substituted for this client

Answer and Explanation

The Correct Answer is A

A. Laxatives are contraindicated in clients who have a small bowel obstruction: This is the correct answer. Laxatives like senna are contraindicated in the presence of a bowel obstruction as they can increase peristalsis and pressure in the bowel, leading to complications such as perforation.
B. An osmotic laxative, such as magnesium citrate, should be substituted in this client: This is incorrect. Osmotic laxatives are also contraindicated in bowel obstruction because they can draw water into the bowel and worsen the obstruction or cause severe complications.
C. The prescribed medication should be administered via NG route rather than the oral route for this client: This is incorrect. Administering any form of laxative via the NG route does not address the contraindication in bowel obstruction and is not a safe practice in this context.
D. Bulk-forming laxatives such as psyllium should be substituted for this client: This is incorrect. Bulk-forming laxatives are also contraindicated in bowel obstruction due to the risk of worsening the obstruction and causing complications.

Correct Answer is A

Explanation

A. Replacement therapy with pancreatic enzymes: Pancreatic insufficiency results in a lack of digestive enzymes, leading to malabsorption of nutrients. Enzyme replacement therapy is essential to aid in digestion and nutrient absorption.
B. Treatment with stimulant laxatives: Stimulant laxatives are used to treat constipation by increasing bowel motility. They do not address the underlying enzyme deficiency in pancreatic insufficiency and can potentially cause further nutrient loss.
C. Treatment with PPIs to decrease stomach acid: Proton pump inhibitors (PPIs) reduce stomach acid production and are used for conditions like GERD. They do not address the enzyme deficiency caused by pancreatic insufficiency.
D. Decrease food intake: Reducing food intake does not treat pancreatic insufficiency and can lead to malnutrition. The goal is to support normal digestion and nutrient absorption through enzyme replacement.

A. The nose and paranasal sinuses B. The nose, nasal cavity, pharynx, and the lungs C. The nose, nasal cavity, pharynx, and paranasal sinuses D. The lungs and associated structures

Correct Answer is C

Explanation

A. The nose and paranasal sinuses: This is partially correct, but it does not include all the structures of the upper respiratory tract. It misses the nasal cavity and the pharynx.
B. The nose, nasal cavity, pharynx, and the lungs: This is incorrect because the lungs are part of the lower respiratory tract, not the upper respiratory tract.
C. The nose, nasal cavity, pharynx, and paranasal sinuses: This is the correct answer. The upper respiratory tract includes the nose, nasal cavity, pharynx, and paranasal sinuses. These structures are involved in air conduction, filtration, humidification, and protection.
D. The lungs and associated structures: This is incorrect as the lungs are part of the lower respiratory tract, which also includes the bronchi and bronchioles.
