The nurse is caring for a pregnant client at 24 weeks. The client voids before the nurse measures the fundal height. Which finding by the nurse would be expected in assessment of this client?

  1. a fundal height of 22 to 26 cm
  2. a fundal height of 27 to 30 cm
  3. a fundal height of 29 to 33 cm
  4. a fundal height of 31 to 34 cm
Number 1 is correct.
Rationale: From gestational weeks (GW) 18 to 30, the height of the fundus in centimeters is approximately the same as the number of weeks of gestation ±2 GW if the client’s bladder is empty. With a full bladder, as much as a 3 cm variation is possible.
