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.

The nurse should administer 10 mL of amoxicillin oral suspension 125 mg/5 mL to give the client a total dose of 250 mg.

Choice B is not the best answer because administering 5 mL of amoxicillin oral suspension 125 mg/5 mL would only give the client a total dose of 125 mg, which is not enough.
Choice C is not the best answer because administering 8 mL of amoxicillin oral suspension 125 mg/5 mL would give the client a total dose of 200 mg, which is not enough.
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.
