The nurse observes that there are reddened areas on the cheekbones of a client receiving oxygen per nasal cannula at 3 L/minute, and the client's oxygen saturation level is 92%. Which intervention would the nurse implement?

Choice A reason: This is the correct action to take when the nurse hears loud Korotkoff sounds immediately after releasing the air valve. This indicates that the cuff was not inflated high enough to occlude the arterial blood flow and the initial systolic reading was inaccurate. The nurse should release the air, wait for 15 to 30 seconds, and then reinflate the cuff to 30 mm Hg above the first systolic sound. This will ensure a more accurate measurement of the blood pressure.

Choice B reason: This is not the correct action to take when the nurse hears loud Korotkoff sounds immediately after releasing the air valve. Continuing the blood pressure assessment until the last Korotkoff sound is heard will result in a lower systolic reading and a higher diastolic reading than the actual blood pressure of the client. The nurse should release the air and reinflate the cuff to 30 mm Hg above the first systolic sound.

Choice C reason: This is not the correct action to take when the nurse hears loud Korotkoff sounds immediately after releasing the air valve. Repositioning the stethoscope in the antecubital fossa over the palpable brachial pulse point will not change the fact that the cuff was not inflated high enough to occlude the arterial blood flow. The nurse should release the air and reinflate the cuff to 30 mm Hg above the first systolic sound.

Choice D reason: This is not the correct action to take when the nurse hears loud Korotkoff sounds immediately after releasing the air valve. Inflating the cuff quickly to a higher mm Hg reading than the previously auscultated systolic sound will cause discomfort and pain to the client and may damage the blood vessels. The nurse should release the air and reinflate the cuff to 30 mm Hg above the first systolic sound.

Choice A Reason: This is incorrect because palpating the suprapubic region for distention can be inaccurate and unreliable, as it can be affected by factors such as obesity, abdominal muscle tone, and bowel gas.

Choice B Reason: This is correct because scanning the client's bladder after voiding can measure the post-void residual urine volume, which indicates the amount of urine left in the bladder after urination. A high post-void residual urine volume can indicate urinary retention.

Choice C Reason: This is incorrect because reviewing the chart for number of voids over last 24 hours can provide information about the frequency of urination, but not the amount or completeness of urination.

Choice D Reason: This is incorrect because evaluating the client for urinary incontinence can assess the involuntary loss of urine, but not the ability to empty the bladder completely.
