A nurse is preparing to administer morphine 8 mg IV intermittent bolus to a client. The amount available is morphine 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
To calculate the amount of morphine to administer, we can use the following formula:
Amount of medication (mL) = Desired dose (mg) / Concentration (mg/mL)
In this case, the desired dose is 8 mg and the concentration is 10 mg/mL.
Amount of medication (mL) = 8 mg / 10 mg/mL
Amount of medication (mL) = 0.8 mL
Therefore, the nurse should administer 0.8 mL of morphine.

Correct Answer is C
Explanation
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.
Correct Answer is D
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.
