A nurse is preparing to administer amoxicillin 320 mg PO every 12 hours to an infant. The amount available is amoxicillin suspension 400 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["4.0"]

Step 1: Determine the dosage required. 320 mg

Step 2: Determine the concentration of the suspension. 400 mg per 5 mL

Step 3: Calculate the volume needed. 320 mg ÷ 400 mg per 5 mL = 320 ÷ 400 × 5 = 0.8 × 5 = 4 mL

The nurse should administer 4.0 mL per dose.

Correct Answer is C

Explanation

A: Clostridium difficile infection typically develops after prolonged antibiotic use and is not the most likely cause of diarrhea immediately after starting enteral feeding.

B: Antibiotic therapy can cause diarrhea, but it is not the most likely cause in this scenario where the diarrhea started soon after beginning enteral feeding.

C: Formula intolerance is the most likely cause of diarrhea shortly after starting enteral feeding. The patient’s digestive system may not tolerate the formula well, leading to diarrhea.

D: Bacterial contamination is a possible cause but is less likely to cause immediate diarrhea after starting enteral feeding compared to formula intolerance. Proper handling and preparation of the formula should minimize this risk.

A. Administer the medication and monitor the patient frequently. B. Refuse to give the medication and notify the nurse supervisor. C. Give the patient hydromorphone, as it was meant to be written. D. Call the health care provider to clarify the order.

Correct Answer is D

Explanation

A: Administering the medication and monitoring the patient frequently is not appropriate because phenytoin is not indicated for pain management.

B: Refusing to give the medication and notifying the nurse supervisor is a step in the right direction, but the nurse should also seek clarification from the health care provider.

C: Giving the patient hydromorphone without clarification is not appropriate. The nurse must verify the order with the health care provider.

D: Calling the health care provider to clarify the order is the correct action. This ensures that the correct medication is administered as intended.
