A nurse is providing education to a client who is reviewing a consent form for a surgical procedure. Which of the following statements by the client indicates an understanding of the consent?

Choice A reason: Measuring the apical pulse (at the heart) simultaneously with the radial pulse (at the wrist) by two nurses accurately detects a pulse deficit, which occurs when heartbeats do not translate to peripheral pulses, often in arrhythmias like atrial fibrillation. This method quantifies the difference, aiding diagnosis and treatment, making it the correct approach.
Choice B reason: Comparing carotid pulses at rest and after standing assesses orthostatic changes, not a pulse deficit. A pulse deficit reflects a discrepancy between central and peripheral pulses, not positional changes. This action is irrelevant to detecting pulse deficits, as it does not compare simultaneous heart and peripheral pulse rates.
Choice C reason: Deflating a blood pressure cuff while palpating the brachial pulse is used to measure blood pressure, not to assess a pulse deficit. This method does not compare central and peripheral pulses simultaneously, which is necessary to identify a deficit, making it an incorrect approach for this assessment.
Choice D reason: Assessing both radial pulses simultaneously evaluates symmetry but not a pulse deficit, which requires comparing the apical (heart) pulse with a peripheral pulse. This method misses the central-peripheral comparison critical for detecting discrepancies caused by arrhythmias, making it inadequate for assessing a pulse deficit.

Choice A reason: Decreasing fluid intake to firm stools is incorrect, as adequate hydration (2-3 L/day) is essential to prevent constipation, especially with opioids like oxycodone, which slow intestinal motility. Low fluid intake hardens stools, exacerbating constipation risk by reducing water content in the colon, indicating a misunderstanding of prevention strategies.
Choice B reason: Increasing dietary fiber intake (25-35 g/day) adds bulk to stools, stimulating peristalsis and counteracting opioid-induced slowed motility. Soluble and insoluble fiber, found in fruits, vegetables, and whole grains, promotes regular bowel movements. This statement reflects correct understanding of dietary measures to prevent constipation during opioid therapy.
Choice C reason: Taking a laxative only when constipated is reactive, not preventive. Opioids like oxycodone commonly cause constipation by reducing peristalsis via mu-opioid receptors in the gut. Prophylactic use of stool softeners or laxatives is recommended to maintain regular bowel movements, making this statement incorrect as it lacks a preventive approach.
Choice D reason: Exercising less to conserve energy worsens constipation, as physical activity stimulates intestinal motility, countering opioid-induced slowing. Regular movement, like walking, promotes bowel function by enhancing peristalsis and blood flow to the gut. This statement indicates a misunderstanding, as reduced activity increases constipation risk.
