1.
2.
3.

The Correct Answer is B
The nurse should administer 2 tablets.
Since each tablet contains 1.5 mg of dexamethasone, to administer a dose of 3 mg, the nurse should give 3 mg / 1.5 mg/tablet = 2 tablets.
Choice A is incorrect because 1 tablet would only provide a dose of 1.5 mg.
Choice C is incorrect because 3 tablets would provide a dose of 4.5 mg.
Choice D is incorrect because 4 tablets would provide a dose of 6 mg.

Explanation
The nurse should set the IV flow rate to deliver 100 gtt/min.
To calculate the flow rate in gtt/min, you can use the formula: (Volume to be infused (mL) x Drop factor (gtt/mL)) ÷ Time (min) = Flow rate (gtt/min).
Plugging in the values from the question: (100 mL x 60 gtt/mL) ÷ 60 min = 100 gtt/min.
Correct Answer is ["B","C","D"]
Explanation
Albuterol is an inhaled medication that can quickly relieve the symptoms of asthma.
Classified as a short-acting beta-agonist (SABA) and bronchodilator, albuterol relaxes the muscles in your airways that tighten during an asthma attack.
This causes the airways in the lung to increase in size, which allows air to move more freely through them1.
This can help prevent wheezing, open airways and decrease coughing.

Choice A: The medication will increase the amount of mucus is not a correct answer because albuterol does not increase the amount of mucus.
