A nurse is monitoring a client’s oxygen saturation using a pulse oximeter. The client’s oxygen saturation is 88% on 2 L/min of oxygen via nasal cannula.
Which of the following actions should the nurse take?
Reposition the sensor probe.
Apply a cooling blanket to the client.
Place the client in a side-lying position.
Ambulate the client.
The Correct Answer is A
The client’s oxygen saturation is 88% on 2 L/min of oxygen via nasal cannula, which is below the normal range of 95% to 100%.
This could indicate that the client is not receiving enough oxygen or that the pulse oximeter is not working properly.
The nurse should first check the sensor probe for any problems, such as poor attachment, nail polish, cold extremities, or motion artifact.
Repositioning the sensor probe may improve the accuracy of the reading and help the nurse determine the next course of action.
Choice B. Apply a cooling blanket to the client is wrong because a cooling blanket is used to lower the body temperature of a client with fever or hyperthermia.
It has no effect on the oxygen saturation level.
Choice C. Place the client in a side-lying position is wrong because a side-lying position may not improve the oxygenation of the client.
A more appropriate position would be a high Fowler’s position, which allows for maximum lung expansion and gas exchange.
Choice D. Ambulate the client is wrong because ambulating the client may worsen the oxygen saturation level if the client has a respiratory condition that causes hypoxemia.
The nurse should assess the client’s respiratory status and oxygen therapy before ambulating the client.

Correct Answer is D
Explanation
It can also increase the risk of denture stomatitis and pneumonia.
Dentures should be removed overnight and soaked in a denture-cleansing solution.
Choice A is wrong because rinsing dentures after meals can help remove food debris and prevent plaque buildup.
Choice B is wrong because soaking dentures in water after removal can prevent them from drying out and losing their shape.
However, water alone is not enough to disinfect dentures, so a denturecleansing solution should also be used.
Choice C is wrong because applying an adhesive to seal dentures in place can improve the fit and comfort of dentures.
However, adhesive should not be used as a substitute for poorly fitting dentures, and any excess adhesive should be removed by brushing.
Correct Answer is B
Explanation
This type of aphasia is caused by damage to the frontal lobe of the brain, which affects the ability to produce language.
People with expressive aphasia can understand speech and know what they want to say, but they have difficulty saying words or forming sentences.
They may speak in short phrases that require a lot of effort.
Choice A is wrong because receptive aphasia is a type of fluent aphasia that affects the ability to comprehend language.
People with receptive aphasia have difficulty understanding speech and may produce meaningless words or sentences.
Choice C is wrong because global aphasia is the most severe type of aphasia that affects both the production and comprehension of language.
People with global aphasia cannot speak many words and do not understand speech.
They also cannot read or write.
Choice D is wrong because sensory aphasia is not a common term for a type of aphasia.
It may refer to Wernicke’s aphasia, which is another type of fluent aphasia that affects the ability to produce meaningful language.
People with Wernicke’s aphasia can speak fluently but often use incorrect or invented words or phrases.
