A nurse is about to administer a daily dose of potassium chloride 20 mEq suspension orally.
The available amount is potassium chloride suspension 10 mEq/mL.
How many mL should the nurse administer?
The Correct Answer is ["2"]
Step 1: Determine the amount of medication needed. The order is for 20 mEq of potassium chloride. The available amount is 10 mEq/mL.
Step 2: Calculate the volume of medication to administer. Volume = Ordered dose ÷ Available concentration Volume = 20 mEq ÷ 10 mEq/mL = 2 mL So, the nurse should administer 2 mL of potassium chloride suspension.

Correct Answer is D
Explanation
Choice A rationale
Clamping the patient’s chest tube is not the appropriate action. Clamping the tube can lead to tension pneumothorax, which is a life-threatening condition.
Choice B rationale
Increasing the patient’s wall suction is not the correct action. The sensation of chest burning is not related to the level of suction. Increasing the suction could potentially cause more harm.
Choice C rationale
Stripping the patient’s chest tube is not recommended. This action can cause negative pressure in the chest and can lead to injury of the lung tissue.
Choice D rationale
Repositioning the patient is the correct action. The sensation of chest burning could be due to the position of the chest tube. Repositioning the patient may alleviate the discomfort.
Correct Answer is C
Explanation
Choice A rationale
Streptococcal pharyngitis, also known as strep throat, is a bacterial infection that causes inflammation and pain in the throat. This condition is spread through respiratory droplets, not through the air, and does not require airborne precautions.
Choice B rationale
Scabies is caused by a mite infestation, not an airborne pathogen. It is spread through direct skin-to-skin contact and does not require airborne precautions.
Choice C rationale
Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing, and the measles virus can live for up to two hours in an airspace where the infected person coughed or sneezed. Therefore, a patient with measles requires airborne precautions.
Choice D rationale
Pertussis, also known as whooping cough, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. It spreads through close contact with respiratory droplets when an infected person coughs or sneezes. It is typically managed with droplet precautions, not airborne precautions.
