A nurse is caring for a client who is receiving diazepam as sedation for an endoscopy, Which of the following antidotes should the nurse have on hand during the procedure?
Naloxone
Atropine
Flumazenil
Neostigmine
The Correct Answer is C
Flumazenil is the antidote for diazepam, which is a benzodiazepine. Flumazenil is a selective antagonist that can reverse the sedative effects of benzodiazepines and is commonly used in cases of benzodiazepine overdose or to reverse sedation after procedures.
Naloxone (A) is the antidote for opioid overdose and would not be appropriate for reversing the effects of diazepam.
Atropine (B) is an anticholinergic medication used to increase heart rate and is not specific to the reversal of diazepam sedation.
Neostigmine (D) is a cholinesterase inhibitor used to reverse the effects of non-depolarizing neuromuscular blocking agents and is not indicated for reversing the effects of diazepam.

Explanation
When providing discharge teaching to a client with a prescription for enoxaparin, the nurse should include the instruction to expel the air bubble prior to injecting the medication. Enoxaparin is a type of anticoagulant medication that is administered as a subcutaneous injection.
Here's why the other options are incorrect:
A. Insert the needle at a 45 angle: Enoxaparin is typically administered as a subcutaneous injection, where the needle is inserted at a 90-degree angle (straight into the skin). A 45-degree angle is used for intramuscular injections, but it is not appropriate for enoxaparin administration.
B. Inject the medication into a muscle: Enoxaparin is not intended to be injected into a muscle. It is a low-molecular-weight heparin designed for subcutaneous administration, meaning it is injected just below the skin into the fatty tissue.
C. Rub the injection site following administration: Rubbing the injection site after administering enoxaparin or any other subcutaneous medication is not recommended. Rubbing the site can cause irritation and bruising. Instead, the nurse should apply gentle pressure with a cotton ball or gauze pad for a few seconds after the injection to help minimize bleeding.
Correct Answer is ["18.8"]
Explanation
To calculate the rate at which the IV pump should deliver dopamine, we can follow these steps:
Step 1: Convert the weight of the client from pounds to kilograms.
220 lb ÷ 2.2 = 100 kg (rounded to the nearest whole number)
Step 2: Calculate the total dose of dopamine per minute.
5 mcg/kg/min × 100 kg = 500 mcg/min
Step 3: Convert the dose from micrograms (mcg) to milligrams (mg).
500 mcg/min ÷ 1000 = 0.5 mg/min
Step 4: Determine the infusion rate in milliliters per hour (mL/hr).
The total volume of the solution is 250 mL.
The total dose of dopamine is 400 mg.
So, the infusion rate is (0.5 mg/min ÷ 400 mg) × 250 mL = 0.3125 mL/min.
Step 5: Convert the infusion rate from mL/min to mL/hr.
0.3125 mL/min × 60 min/hr = 18.75 mL/hr (rounded to the nearest tenth).
Therefore, the nurse should set the IV pump to deliver 18.8 mL/hr (rounded to the nearest tenth).
