The nurse is providing preoperative teaching to a patient to have an operation on their colon for cancer. The nurse should take which of the following actions regarding informed consent?

Choice A reason: Donning sterile gloves is unnecessary for abdominal assessment, as it requires clean gloves to prevent infection. Sterile gloves are used for invasive procedures, not palpation or auscultation. This action is irrelevant to preparing for palpation and wastes resources, per infection control and assessment protocols.

Choice B reason: Elevating the patient’s head may relax abdominal muscles but is not required before palpation. Auscultation precedes palpation to avoid altering bowel sounds by pressure. Elevating the head does not address the need for accurate bowel sound assessment, making it less critical, per abdominal examination sequence.

Choice C reason: Percussing all four quadrants follows auscultation and inspection, not precedes palpation. Percussion assesses organ size or fluid but may disrupt bowel sounds if done before auscultation. Auscultation is prioritized to capture unaltered sounds, ensuring a systematic abdominal assessment, per clinical examination guidelines.

Choice D reason: Auscultating bowel sounds before palpation is essential, as palpation may alter peristalsis, leading to inaccurate findings. Listening for hypoactive or hyperactive sounds identifies abnormalities like obstruction, guiding further assessment. This sequence preserves diagnostic accuracy, aligning with systematic abdominal examination protocols.

Choice A reason: Assessing blood pressure is important but does not directly confirm an irregular pulse. An irregular radial pulse may indicate arrhythmias like atrial fibrillation, affecting cardiac output. Blood pressure measurement assesses hemodynamic status but cannot verify pulse rhythm accuracy, as it relies on arterial pressure, not direct cardiac electrical activity, making it a secondary step.

Choice B reason: Checking the apical pulse, auscultated at the heart’s apex, directly assesses cardiac rhythm and rate, confirming an irregular radial pulse. Irregular rhythms, like atrial fibrillation, disrupt normal atrial-ventricular conduction, detectable via auscultation. This step ensures accurate assessment of cardiac electrical activity and stroke volume, critical for identifying arrhythmias and guiding further interventions.

Choice C reason: Obtaining the pulse in the other arm may detect peripheral inconsistencies but does not confirm cardiac rhythm. An irregular radial pulse likely reflects a cardiac arrhythmia, not a localized vascular issue. Apical pulse assessment directly evaluates heart activity, making it more relevant than bilateral radial checks for verifying rhythm disturbances and planning appropriate interventions.

Choice D reason: Notifying the healthcare provider is premature without confirming the irregular rhythm. An irregular pulse may indicate an arrhythmia, requiring validation via apical pulse to assess cardiac electrical activity. Immediate notification bypasses critical assessment steps, potentially leading to misdiagnosis or delayed care, as the nurse must first gather accurate data to inform the provider.
