A nurse is teaching a client who has an ileostomy about the care of their stoma. Which of the following statements by the client indicates an understanding of the teaching?

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: Washing hands for 10 seconds with hot water is insufficient; at least 20 seconds with soap and warm water is recommended to remove pathogens post-gardening. Hot water alone is ineffective, so this statement reflects incomplete understanding, making it incorrect.
Choice B reason: Visiting a nephew with chickenpox 5 days after sores crust indicates understanding, as the virus is no longer contagious then. This aligns with CDC guidelines for varicella, protecting the pregnant client and fetus, making it the correct statement.
Choice C reason: Cleaning a cat’s litter box during pregnancy risks toxoplasmosis, which can harm the fetus. Pregnant women should avoid this task, so this statement shows a lack of understanding, making it incorrect for infection prevention.
Choice D reason: Avoiding anyone with a cold sore is overly restrictive, as herpes simplex transmission requires direct contact. General avoidance without context reflects misunderstanding, as precautions like avoiding kissing suffice, making this incorrect.
