A nurse is preparing to administer cefaclor 500 mg PO every 12 hours.
If the available cefaclor oral suspension is 250 mg/5 mL, how many mL should the nurse administer per dose?
The Correct Answer is ["10 "]
Step 1: We need to find out how many mL of cefaclor oral suspension the nurse should administer per dose.
Given:
The doctor’s order is 500 mg of cefaclor.
The available cefaclor oral suspension is 250 mg/5 mL.
Step 2: We set up a proportion to find out the volume of the oral suspension that contains 500 mg of cefaclor.
Let’s denote the volume we are looking for as X mL. So, we have:
250 mg : 5 mL = 500 mg : X mL
Step 3: We cross-multiply and solve for X. 250 mg × X mL = 500 mg × 5 mL
Step 4: We divide both sides by 250 mg. X mL = (500 mg × 5 mL) ÷ 250 mg
Step 5: We calculate X.
X = (500 mg × 5 mL) ÷ 250 mg = 10 mL
So, the nurse should administer 10 mL of the cefaclor oral suspension per dose.

Correct Answer is ["14 "]
Explanation
The medication should be discarded 14 days after reconstitution. This is a standard guideline for most reconstituted medications to ensure potency and prevent bacterial growth.
Correct Answer is D
Explanation
The correct answer is choice D. Regular insulin 35 units subcutaneously 30 minutes before meals.
Choice A rationale:
Desvenlafaxine 50 mg PO daily is a standard dosage for this antidepressant medication and does not typically require clarification unless there are specific patient concerns or contraindications.
Choice B rationale:
Ketorolac nasal spray, one spray in each nostril every 6 hours as needed for moderate pain, is an appropriate prescription. However, it is important to monitor for potential side effects, especially with prolonged use.
Choice C rationale:
Oxycodone 10 mg PO every 4 hours as needed for severe pain is a common prescription for managing severe pain. The nurse should ensure the patient is monitored for signs of opioid misuse or adverse effects.
Choice D rationale:
Regular insulin 35 units subcutaneously 30 minutes before meals is an unusually high dose and could lead to hypoglycemia. This prescription should be clarified with the provider to ensure it is accurate and safe for the patient.
