While suctioning a client's nasopharynx, the nurse observes that the client's oxygen saturation remains at 94%, which is the same reading obtained prior to starting the procedure. Which action should the nurse take in response to this finding?

Complete the intermittent suction of the nasopharynx.

Apply an oxygen mask over the client's nose and mouth.

Reposition the pulse oximeter clip to obtain a new reading.

Stop suctioning until the pulse oximeter reading is above 95%.

Answer and Explanation

The Correct Answer is A

Choice A reason: If the oxygen saturation remains stable during the procedure, it indicates that the suctioning is not adversely affecting the client's oxygenation, and the nurse can safely continue.

Choice B reason: Applying an oxygen mask is not necessary if the oxygen saturation is stable and within a safe range.

Choice C reason: Repositioning the pulse oximeter clip is only necessary if there is a concern about the accuracy of the reading, not when the reading is stable.

Choice D reason: There is no need to stop suctioning if the oxygen saturation is stable at 94%, as this is within the acceptable range for most clients.

Correct Answer is B

Explanation

Choice A reason: Observing the color and amount of urine is important for assessing kidney function and hydration status but is not the most critical intervention for hypokalemia, which can have immediate life-threatening cardiac effects.

Choice B reason: Determining the apical pulse rate and rhythm is the most important intervention. Hypokalemia can lead to serious cardiac arrhythmias, and the apical pulse is the most accurate non-invasive way to assess cardiac rhythm and rate.

Choice C reason: Comparing muscle strength bilaterally is important for assessing the impact of hypokalemia on muscle function, but it is not as immediately life-threatening as cardiac effects.

Choice D reason: Assessing the strength of deep tendon reflexes can help evaluate neuromuscular involvement in hypokalemia but is less critical than monitoring for cardiac arrhythmias.

A. Skin turgor. B. Weight. C. Blood pressure. D. Lung sounds.

Correct Answer is B

Explanation

Choice A reason: Skin turgor is a method to assess hydration status, but it is not the most accurate indicator of fluid balance in a patient with fluid volume overload.

Choice B reason: Monitoring weight is the most accurate method to assess fluid balance. A sudden increase or decrease in weight is indicative of fluid changes.

Choice C reason: Blood pressure can be affected by fluid volume changes, but it does not provide a direct measure of fluid balance.

Choice D reason: Lung sounds can indicate fluid overload in the lungs but do not give a complete picture of overall fluid balance.
