The symptoms mentioned—mottled skin, a large fontanel (soft spot on the baby's head), a large tongue, lethargy, and difficulty feeding—are characteristic of hypothyroidism inneonates.
Mottled skin can occur due to decreased circulation and low body temperature associated with hypothyroidism. A large fontanel and tongue are common physical features seen in infants with hypothyroidism. Lethargy and poor feeding are also typical signs of this condition.

Correct Answer is A
Explanation
The most appropriate statement by the nurse to a 15-year-old whose friend has mentioned suicide is option A. The statement acknowledges the seriousness of the situation and emphasizes the importance of taking the friend's threat seriously. It also highlights the need for immediate help and intervention. Suicide threats should never be dismissed or taken lightly, and it is crucial to involve professionals who can provide appropriate support and assistance.
"Tell your friend to come to the clinic immediately," in option B is incorrect because places the responsibility solely on the 15-year-old to relay the message to their friend, which may not be the most effective or timely approach.
"If your friend mentions suicide again, get your friend some help," in (option C) is incorrect because it does not address the urgency of the situation. Waiting for the friend to mention suicide again before acting may lead to potential harm.
"You need to gather details about your friend's suicide plan," is incorrect because places the responsibility on the 15-year-old to gather information about the friend's suicidal intentions. While understanding the situation and obtaining relevant details is important, the immediate priority is ensuring the friend's safety and seeking professional help.
Correct Answer is C
Explanation
Infants and children have open growth plates, also known as epiphyseal plates, at the ends of
their long bones. These plates are responsible for bone growth and are not fully fused until
the child reach skeletal maturity. Due to the presence of open growth plates, infants and
children are more prone to fractures because their bones are still developing and are less
dense than those of adults.
Their bones have less blood flow in (Option A) is incorrect because cchildren’s bones
actually have a greater blood flow compared to adults. This increased blood flow supports the
rapid growth and development of bones in children.
Growth occurs in children as a result of an increase in the number of muscle fibers in (option
B) is incorrect because ggrowth in children occurs primarily due to the elongation and
thickening of existing muscle fibres, not an increase in their number. This option inaccurately
suggests that children's muscles increase in fibber count to facilitate growth.
Because soft tissues are resilient in children, dislocations and spirals are less common than in
adults in (Option D is) incorrect. While soft tissues may be more resilient in children, it does
not mean that dislocations and sprains are less common than in adults. In fact, children's
ligaments and joint structures are still developing and may be more susceptible to injuries
such as sprains and dislocations compared to adults.
