A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which of the following statements should the nurse make?

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: Starting work in a parking garage while on warfarin does not inherently indicate a need for referral unless specific risks (e.g., injury prone to bleeding) are present. Without additional concerns, this situation is routine, making it incorrect for requiring further care.
Choice B reason: Increased urinary frequency with bumetanide, a diuretic, is an expected side effect, not requiring referral unless severe or accompanied by electrolyte imbalances. This is a normal response, so it does not warrant further care, making it incorrect.
Choice C reason: An induration 48 hours after a Mantoux test suggests a positive tuberculosis result, requiring referral for chest X-ray and further evaluation. This finding indicates potential latent or active TB, a significant health concern, making it the correct choice for referral.
Choice D reason: Being 1 day postoperative after knee replacement is expected, with routine monitoring for complications like infection or thrombosis. Without specific issues, this does not require referral beyond standard postoperative care, making it incorrect.
