Final answer:
For a low-risk primigravida at 28-weeks gestation, a pulse increase of 10 beats per minute is a normal physiological change and should be considered within normal limits. Proteinuria, glucosuria, and a fundal height of 22 centimeters are not within normal limits and could indicate potential complications.
Step-by-step explanation:
The assessment finding that should be considered within normal limits for a low-risk primigravida at 28-weeks gestation is A. Pulse increase of 10 beats/minute. During pregnancy, it is common for a woman's pulse rate to increase to compensate for the additional blood volume needed to support the placenta and fetus. A slight increase in pulse is a normal physiological change. Option B, Proteinuria, and option C, Glucosuria, are not typically considered within normal limits as they can indicate possible complications such as pre-eclampsia or gestational diabetes, respectively. Regarding option D, Fundal height 0f 22 centimeters, the fundal height in centimeters typically approximates the number of weeks of gestation, so at 28-weeks gestation, a fundal height of 28 centimeters would be within normal limits. A measurement of 22 centimeters might be concerning for potential intrauterine growth restriction (IUGR). Therefore, the pulse increase is the most appropriate choice.
