1.25ml

6.25ml

6.3mg

6 mg

Answer and Explanation

The Correct Answer is B

A. 1.25ml: The dosage of 20mg/5ml means 1ml contains 4mg. To get 25mg, you need more than 1.25ml.

B. 6.25ml: Since 20 mg is in 5ml, to administer 25mg, you can use the following calculation:

25mg * = 6.25ml

C. 6.3mg: This is incorrect because the dosage needed is 25mg, not 6.3mg.

D. 6mg: The prescribed dose is 25mg, not 6mg.

Correct Answer is C

Explanation

A. Bisacodyl: A stimulant laxative that promotes bowel movements but may not be effective in refractory opioid-induced constipation.

B. Mineral oil: A lubricant that softens stools but does not address the opioid-specific cause of constipation.

C. Methylnaltrexone: A peripherally acting opioid antagonist that specifically targets opioid-induced constipation without affecting pain relief, making it the best option for refractory cases.

D. Docusate: A stool softener that is typically ineffective alone for severe opioid-induced constipation.

A. Perforation B. Obstruction C. Infection D. Constipation

Correct Answer is A

Explanation

A. Perforation: A temperature of 102.4° F and abdominal rigidity are suggestive of peritonitis, which is a potential complication of diverticulosis. Perforation of a diverticulum can lead to leakage of intestinal contents into the abdominal cavity, causing infection and inflammation.

B. Obstruction: Although obstruction can occur in diverticulosis, it typically causes symptoms such as bloating, abdominal distention, and pain, not fever and rigidity.

C. Infection: While infection can occur with diverticulosis, fever and rigidity in this scenario are more likely due to perforation leading to peritonitis, which is a more severe condition.

D. Constipation: While constipation can exacerbate diverticulosis, it would not typically cause fever or abdominal rigidity.
