A nurse is assessing a client who reports feeling dizzy while getting out of bed. The nurse suspects orthostatic hypotension related to a medication the client is taking Which of the following medications should the nurse identify as likely causing this adverse effect?
Dabigatran
Levothyroxine
Isoproterenol
Furosemide
The Correct Answer is D
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.

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 ["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).
