A nurse is evaluating the effectiveness of interventions for four clients with unexpected vital signs. Which finding requires follow up?

• A. 8 mm Hg difference in systolic BP when moving from sitting to standing
• B. Radial pulse strength +4 bilaterally
• C. Tympanic temperature 35.9 C (96.6 F)
• D. Newborn respiratory rate 56/min while sleeping

Answer: (B)

A rhythm you can’t ignore is an unusually strong, bounding pulse that is the same on both wrists. When pulse strength is graded, normal is typically 2+, with a wide difference between sides or a pulse that is markedly stronger (like +4) suggesting something beyond a momentary variation. A bounding pulse can reflect a high stroke volume or changes in vascular tone and may accompany conditions such as fever, anemia, hyperthyroidism, dehydration, or fluid overload. Because this finding points to a systemic alteration in cardiovascular dynamics rather than a local issue, it deserves closer assessment and possibly further testing to identify an underlying cause.

The other findings are less alarming in this context: an orthostatic BP difference of 8 mm Hg between sitting and standing can be within normal variation for many people; a tympanic temperature of 35.9 C is below normal but could be due to measurement factors or environment and may not indicate an acute problem by itself; and a newborn respiratory rate of 56/min while sleeping falls within the typical neonatal range.
