A pediatric nurse is assessing a 10-year-old girl with signs of anorexia nervosa.
Which physical assessment finding would support the diagnosis?

Choice A rationale

Notifying the healthcare provider immediately and requesting antibiotics is premature. Slight redness around pin sites without drainage or pain, and stable vital signs, does not immediately indicate a significant infection requiring systemic antibiotics. This initial finding warrants a thorough assessment and local care before escalating to medical intervention.

Choice B rationale

Removing crusting around pin sites can be detrimental. Crusting can serve as a protective barrier. Aggressive removal can introduce bacteria into the pin tract, increasing the risk of infection, or cause unnecessary pain and trauma to the delicate healing tissue. Gentle cleansing is preferred over forceful removal of adherent crusts.

Choice C rationale

Cleansing the pin sites using sterile saline and assessing for signs of infection is the best immediate action. Slight redness without drainage is often a normal inflammatory response to the foreign body and movement. Sterile saline effectively cleanses without irritating the tissue, and continued assessment helps monitor for evolving signs like increased redness, purulent drainage, or fever.

Choice D rationale

Documenting findings as normal and continuing routine assessments is insufficient. While slight redness can be normal, it still requires diligent monitoring and appropriate pin site care to prevent potential complications. Assuming normalcy without active intervention like cleansing could allow a minor irritation to progress to a more serious infection. .

Choice A rationale

At the end of the first trimester, around 12-14 weeks gestation, the uterus is still relatively low in the pelvis. The symphysis pubis serves as a reliable anatomical landmark for locating the fundus of the uterus at this stage. Placing the Doppler just above this bony prominence allows for optimal transmission of sound waves to detect the fetal heart tones.

Choice B rationale

The right upper quadrant contains structures like the liver, gallbladder, and part of the colon. At the end of the first trimester, the uterus is not typically high enough to extend into this region. Therefore, attempting to locate fetal heart tones in this area would be ineffective and unlikely to yield a clear signal, as the fetus is not yet positioned there.

Choice C rationale

Just above the umbilicus is the general location for assessing fetal heart tones later in pregnancy, typically during the second and third trimesters when the uterus has significantly enlarged and risen out of the pelvis. At the end of the first trimester, the uterus is still too small and low for the fetal heart tones to be consistently heard at this location.

Choice D rationale

The left upper quadrant contains the stomach, spleen, and part of the colon. Similar to the right upper quadrant, the uterus is not positioned high enough in the first trimester to extend into this area. Therefore, attempting to locate fetal heart tones in the left upper quadrant would be inappropriate and unlikely to be successful.
