For documenting vital signs, the following documentation made by the nurse indicates an understanding of the teaching:

Pulse 82/min, client sitting in a chair

Temperature 36.9°C (98.4°F)

Respirations auscultated, even at 22/min, client supine

Blood pressure 108/68 mm Hg

Answer and Explanation

The Correct Answer is A

Choice A reason: This documentation is correct as it includes the pulse rate and the client's position when the measurement was taken, which can affect the reading.

Choice B reason: The temperature is documented with the correct unit of measurement, but it does not specify the method of measurement (oral, axillary, tympanic, etc.), which is important for accurate interpretation.

Choice C reason: Respirations should be observed, not auscultated, and the documentation should include the client's position. The term 'even' is unnecessary and could be confusing.

Choice D reason: The blood pressure reading is correctly documented with both systolic and diastolic values. However, it should also include the client's position and the arm in which the measurement was taken for clarity.

Correct Answer is A

Explanation

Choice A reason: The carotid pulse sites should not be checked bilaterally at the same time because palpating both carotid arteries simultaneously can restrict blood flow to the brain and may also stimulate the vagus nerve, potentially causing bradycardia or even syncope.

Choice B reason: The popliteal pulse, located at the back of the knee, can be checked bilaterally without the risk of restricting blood flow to vital organs or stimulating a vagal response.

Choice C reason: The femoral pulse, found in the groin area, can also be checked bilaterally as it does not pose the same risks as the carotid pulse when checked simultaneously.

Choice D reason: The brachial pulse, located on the inside of the arm just above the elbow, is another site that can be checked bilaterally without significant risk.

A. Wrapping the cuff too loosely around the client's arm B. Measuring blood pressure right after the client's mealtime C. Positioning the client's arm above heart level D. Deflating the cuff too slowly

Correct Answer is C

Explanation

The correct answer is: c. Positioning the client’s arm above heart level.

Choice A: Wrapping the cuff too loosely around the client’s arm

Wrapping the cuff too loosely can lead to an inaccurately high blood pressure reading, not a low one. A loose cuff does not compress the artery properly, causing the device to overestimate the pressure needed to occlude the artery.

Choice B: Measuring blood pressure right after the client’s mealtime

Measuring blood pressure right after a meal can cause a slight increase in blood pressure due to the body’s metabolic response to digestion. This is not a common cause of a low blood pressure reading.

Choice C: Positioning the client’s arm above heart level

Positioning the client’s arm above heart level can lead to an inaccurately low blood pressure reading. When the arm is elevated, the hydrostatic pressure decreases, resulting in a lower reading. This is a well-known source of error in blood pressure measurement.

Choice D: Deflating the cuff too slowly

Deflating the cuff too slowly can cause venous congestion, which may lead to an inaccurately high reading rather than a low one. The standard deflation rate is 2-3 mm Hg per second to ensure accurate measurement.
