The nurse preceptor is teaching a newly licensed nurse about blood flow through the heart.
The nurse preceptor knows teaching has been effective when the newly licensed nurse states that the upper chambers of the heart are:.

Choice A rationale:

Obtaining the number of the client’s provider is not the immediate action to take. The client is showing signs of a possible stroke (right-sided weakness and slurred speech), which is a medical emergency.

Choice B rationale:

Finding a location for the client to sit is not the immediate action to take. The client needs medical attention immediately due to the signs of a possible stroke.

Choice C rationale:

Driving the client to the nearest emergency room is not the best action to take. It would be faster and safer to call emergency medical services who are trained to handle such situations.

Choice D rationale:

Calling emergency medical services is the correct action. The client is showing signs of a possible stroke, which requires immediate medical attention.

Choice A rationale:

Hyperventilation is a compensatory mechanism for metabolic acidosis, not a cause. It helps to eliminate carbon dioxide, a weak acid, to balance the pH.

Choice B rationale:

Diarrhea causes loss of bicarbonate, a base, from the body. This can lead to metabolic acidosis as there is an excess of acids.

Choice C rationale:

Salicylate intoxication can cause both respiratory alkalosis and metabolic acidosis. However, it is not the most common cause of metabolic acidosis.

Choice D rationale:

Vomiting leads to loss of gastric acid, a strong acid. This usually results in metabolic alkalosis, not acidosis.
