A patient has been experiencing acute diarrhea. In order to control this condition, the healthcare provider initially orders Lomotil 10 ml (2 teaspoons), four times a day. Every 5 mL (1 teaspoon) contains 2.5 mg of medication. How many milligrams of medication will the patient receive a day?

15 mg

20 mg

10 mg

2.5 mg

Answer and Explanation

The Correct Answer is B

A. 15 mg: This calculation is incorrect because it underestimates the total daily dosage.
B. 20 mg: This calculation is correct. Here’s the breakdown: Each dose is 10 mL (which contains 5 mg), given four times a day. Thus, 5 mg per dose × 4 doses = 20 mg daily.
C. 10 mg: This calculation is incorrect as it only accounts for two doses rather than four daily doses.
D. 2.5 mg: This calculation is incorrect because it represents the dosage per 5 mL (1 teaspoon), not the total daily dosage.

Correct Answer is A

Explanation

A. Take albuterol first. Albuterol is a short-acting beta-agonist (SABA) that acts quickly to dilate the airways. It should be taken first to open the airways, making it easier for the long-acting beta-agonist (LABA), salmeterol, to penetrate deeper into the lungs and provide prolonged bronchodilation.
B. The order of administration does not matter. This is incorrect because the sequence does matter. Taking albuterol first helps to maximize the effectiveness of the subsequent medication by improving airway openness.
C. They should not be taken together: This is incorrect. Albuterol and salmeterol can be used together as part of asthma management. They work through different mechanisms, and using them together can provide both quick relief and long-term control.
D. Take salmeterol first: Taking salmeterol first is not recommended because it is a long-acting bronchodilator that works slowly. The immediate relief provided by albuterol helps to open the airways first, making the use of salmeterol more effective.

A. Laxatives are contraindicated in clients who have a small bowel obstruction. B. An osmotic laxative, such as magnesium citrate, should be substituted in this client C. The prescribed medication should be administered via NG route rather than the oral route for this client. D. Bulk-forming laxatives such as psyllium should be substituted for this client

Correct Answer is A

Explanation

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.
