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.

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
Furosemide, a loop diuretic, is known to cause orthostatic hypotension as an adverse effect. It works by increasing urine output and reducing fluid volume, which can lead to a decrease in blood pressure when standing up, causing dizziness or lightheadedness.
Dabigatran (A) is an anticoagulant used to prevent blood clots and does not typically cause orthostatic hypotension as a side effect.
Levothyroxine (B) is a thyroid hormone replacement medication used to treat hypothyroidism. It does not usually cause orthostatic hypotension.
Isoproterenol (C) is a non-selective beta-adrenergic agonist that is primarily used for cardiac stimulation. It can cause tachycardia and palpitations, but orthostatic hypotension is not a common side effect.
