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 D

Explanation

A. Cetirizine (Zyrtec): Cetirizine is an antihistamine used to treat mild allergic reactions, such as seasonal allergies or mild hives. It is not the treatment of choice for severe allergic reactions like anaphylaxis, which this patient may be experiencing given the symptoms and history of peanut allergy.
B. Diphenhydramine (Benadryl): Diphenhydramine is an antihistamine that can be used for mild to moderate allergic reactions, including urticaria and mild anaphylaxis. While it may be part of anaphylactic treatment, it is not the primary treatment for severe symptoms like difficulty breathing.
C. Guaifenesin: Guaifenesin is an expectorant used to relieve chest congestion and make coughs more productive. It is not appropriate for treating allergic reactions or respiratory distress related to anaphylaxis.
D. Epinephrine: Epinephrine is the first-line treatment for anaphylaxis, which is a severe and potentially life-threatening allergic reaction. It works by rapidly reducing airway swelling, improving breathing, and stabilizing blood pressure. Given the patient's symptoms and history of peanut allergy, epinephrine is the most appropriate medication.

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.
