The registered nurse (RN) observes a licensed practice nurse (LPN) assess a client's vital signs. What action by the LPN warrants intervention by the RN?

Choice A reason: Telling the client that respirations are being counted warrants intervention. Respirations should be assessed unobtrusively because clients may alter their breathing pattern if they know they are being observed. This can lead to inaccurate results. Choice B reason: Assessing axillary temperature instead of oral temperature is acceptable in certain situations, such as when the client cannot safely hold a thermometer in the mouth. While axillary readings may be less accurate, this does not warrant immediate intervention. Choice C reason: Asking the client about their baseline blood pressure is not harmful. It may provide useful information, though it is not a required step in vital sign assessment. This does not warrant intervention. Choice D reason: Listening to the apical pulse at the 5th intercostal space midclavicular line is correct technique. This is the proper anatomical location for auscultating the apical pulse, so no intervention is needed.
