A 7-year-old child is brought to the clinic due to fatigue, slowed growth, and constipation. On examination, the child has dry skin, a puffy face, and a hoarse voice. Which of the following conditions should the nurse suspect?

A. Estrogen is incorrect because, while estrogen promotes uterine growth, blood flow, and development of the mammary glands, it does not primarily maintain the uterine lining or prevent contractions. Estrogen actually increases toward the end of pregnancy and can help sensitize the uterus to oxytocin, promoting labor.

B. Progesterone is correct because it maintains the endometrial lining, supporting implantation and early fetal development, and inhibits uterine contractions throughout pregnancy. By relaxing smooth muscle in the uterus, progesterone helps prevent premature labor and miscarriage. Its levels remain high during most of pregnancy and decrease near term to allow labor to begin.

C. Human Chorionic Gonadotropin (hCG) is incorrect because hCG’s primary role is to signal the corpus luteum to continue producing progesterone during early pregnancy. While essential in the first trimester, it does not directly maintain the uterine lining or prevent contractions throughout pregnancy.

D. Relaxin is incorrect because relaxin primarily relaxes the ligaments of the pelvis and softens the cervix to prepare for labor. It does not maintain the endometrium or inhibit uterine contractions.

A. Ensure the weights hang freely and do not touch the floor to maintain proper traction force is correct. Proper skeletal traction depends on continuous, consistent force applied through the weights. If the weights touch the floor or are obstructed, the traction is disrupted, which can result in malalignment, delayed healing, increased pain, or neurovascular compromise. Maintaining correct traction mechanics is the highest priority to prevent serious complications.

B. Remove the traction weights every 6 hours is incorrect because weights should never be removed unless prescribed. Interrupting traction can cause muscle spasm, malalignment, or delayed fracture healing. Skin breakdown is addressed through regular skin care and positioning, not by removing weights.

C. Limit monitoring of pin sites to once every 24 hours is incorrect because pin sites require frequent assessment (at least every 4–8 hours) for signs of infection, inflammation, or loosening. Infrequent monitoring increases the risk of osteomyelitis or local infection.

D. Place the rope knot in contact with the pulley is incorrect because this would interfere with the smooth functioning of the traction system. The rope must move freely through the pulley to maintain proper tension and alignment.
