A nurse is teaching participants at a community center about advance directives. Which of the following information should the nurse include in the teaching?

Choice A reason: Keeping the drainage bag above waist level promotes urine backflow, increasing infection risk. Bags must be below bladder level to ensure proper urine flow, so this action is incorrect and unsafe, requiring nurse intervention.
Choice B reason: Disconnecting the catheter to empty the bag breaks the closed system, increasing infection risk. The bag should be emptied via the drainage port, so this action is incorrect and requires correction by the nurse.
Choice C reason: Emptying the drainage bag when three-quarters full prevents overfilling, reducing backflow and infection risk. This aligns with proper catheter care protocols, ensuring safety for a fall-risk client, making it the correct technique.
Choice D reason: Using sterile gloves for emptying the drainage bag is unnecessary, as clean gloves suffice for this non-sterile procedure. Sterile gloves are for catheter insertion, so this action is incorrect and inefficient, requiring guidance.

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.
