Correct Answer: A

Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.

Correct Answer: D

Rationale: The correct answer is D. Metformin does not require additional doses for hyperglycemia, and sliding scale insulin is not typically used with metformin. It is important for the client to recognize signs and symptoms of hypoglycemia, report persistent polyuria to the healthcare provider, and take the medication with meals. Teaching the client to use sliding scale insulin for finger stick glucose elevation is not appropriate in this case because metformin is the prescribed medication, and its mechanism of action differs from insulin therapy. The client should be educated on the importance of taking metformin with meals to reduce gastrointestinal side effects and to report any persistent polyuria, which could indicate poor blood sugar control.

Correct Answer: C

Rationale: After rectal surgery, a stool softener is the most appropriate medication to help prevent pain and straining during defecation. Stool softeners work by increasing the water content of the stool, making it easier to pass without discomfort. Bulk-forming agents (Choice A) help add mass to the stool but may not address the immediate post-operative discomfort. Antianxiety agents (Choice B) would address the anxiety but not the physical discomfort. Stimulant cathartics (Choice D) are not recommended after rectal surgery as they can cause cramping and increased bowel movements, potentially exacerbating pain.

Correct Answer: A

Rationale: During the preicteric phase of hepatitis A, the nurse should expect to find RUQ (right upper quadrant) abdominal pain. This pain is common in the early phase of hepatitis A and is associated with liver inflammation. Clay-colored stools (Choice B) are typically seen in the icteric phase when there is a lack of bile flow. Icteric sclera (Choice C) refers to yellowing of the eyes, which is a characteristic of the icteric phase. Pruritus (Choice D), which is itching of the skin, is also more commonly associated with the icteric phase when bile salts accumulate in the skin.

Correct Answer: A

Rationale: Dependent edema in both lower legs is a sign of fluid overload, which can exacerbate dyspnea in patients with COPD. Restricting daily fluid intake can help reduce the edema and alleviate breathing difficulties. A low-protein diet is not necessary unless there are specific renal concerns. Eating meals at the same time daily or limiting high-calorie foods is not directly associated with addressing fluid overload and dyspnea in COPD patients.
