A nurse is measuring the head circumference of a preterm infant.
Which of the following methods should the nurse use to ensure accuracy?
Place a tape measure around the widest part of the head.
Place a tape measure around the forehead and occiput.
Place a tape measure around the forehead and ears.
Place a tape measure around the forehead and chin.
The Correct Answer is A
This is the recommended method for measuring the head circumference of a preterm infant.
It ensures accuracy by capturing the largest dimension of the head, which reflects the growth of the brain.
Choice B is wrong because it does not measure the widest part of the head, which may be above or below the occiput.
Choice C is wrong because it does not measure the widest part of the head, which may be above or below the ears.
Choice D is wrong because it does not measure the widest part of the head, which may be above or below the chin.
The normal range for head circumference at birth for preterm infants born between 32 and 42 weeks gestation is about 25 to 36 cm. Head circumference should be measured and plotted regularly until two years of age for preterm infants.

Correct Answer is A
Explanation
ROP is a condition that affects the blood vessels of the retina in premature infants.
It can cause vision loss or blindness if not treated.
The main treatment for ROP is laser therapy or cryotherapy to stop abnormal blood vessel growth.
However, these treatments do not restore normal vision and may have complications.
Therefore, regular eye exams are needed to monitor the condition and detect any changes or problems.
Choice B is wrong because surgery is not a common treatment for ROP.
Surgery may be done in some cases to reattach the retina if it detaches from the eye wall, but this is a rare and serious complication of ROP.
Choice C is wrong because oxygen therapy can actually worsen ROP.
High levels of oxygen can stimulate the abnormal blood vessel growth in the retina.
Oxygen therapy should be used with caution and only when necessary for premature infants.
Choice D is wrong because glasses do not improve vision in ROP.
Glasses can correct refractive errors such as nearsightedness or farsightedness, but they cannot fix the damage to the retina caused by ROP.
