The nurse is teaching a client about how to use crutches. Which action performed by the client demonstrates to the nurse a correct understanding of how to use the crutches?

Choice A reason: This is not the most important assessment because abdominal girth is not a reliable indicator of fecal impaction. Abdominal girth can vary depending on the client's body type, fluid status, and other factors.

Choice B reason: This is also not the most important assessment because breath sounds are not directly related to fecal impaction. Breath sounds can be affected by respiratory conditions, smoking, allergies, and other factors.

Choice C reason: This is another incorrect choice because bowel sounds are not the most important assessment either. Bowel sounds can be diminished or absent in clients with fecal impaction, but they can also be altered by other gastrointestinal disorders, medications, and dietary factors.

Choice D reason: This is the correct choice because vital signs are the most important assessment prior to initiating digital removal of a fecal impaction. Vital signs can indicate the client's hemodynamic status, pain level, and risk of complications such as vagal stimulation, perforation, or infection. The nurse should monitor the client's blood pressure, pulse, respirations, and temperature before, during, and after the procedure.

Choice A reason: Continuing the blood pressure assessment until the last Korotkoff sound is heard is not the best action to implement next. It may result in an inaccurate measurement of the diastolic pressure, as the cuff pressure may be too low to detect the sound.

Choice B reason: Repositioning the stethoscope in the antecubital fossa over the palpable brachial pulse point is not a necessary action to implement next. It may not affect the accuracy of the blood pressure measurement, as the nurse already hears the Korotkoff sounds clearly.

Choice C reason: Inflating the cuff quickly to a higher mm Hg reading than the previously auscultated systolic sound is not a safe action to implement next. It may cause discomfort and injury to the client, as the cuff pressure may be too high and occlude the blood flow.

Choice D reason: Releasing the air and reinflating the cuff to 30 mm Hg above the client's previous systolic reading is the best action to implement next. It helps to avoid the auscultatory gap, which is a period of silence between the systolic and diastolic pressures. It also ensures that the cuff pressure is high enough to detect the true systolic and diastolic pressures.
