Which of the following steps is correct when measuring head circumference in an infant?
Measure from the back of the head to the forehead.
Place the measuring tape above the eyebrows and around the widest part of the head.
Measure from the chin to the top of the head.
Wrap the measuring tape tightly around the neck.
The Correct Answer is B
Choice A rationale
Measuring from the back of the head to the forehead is not the correct method for measuring head circumference in an infant. The measurement should be taken around the widest part of the head, which is typically above the eyebrows and ears.
Choice B rationale
Placing the measuring tape above the eyebrows and around the widest part of the head is the correct method for measuring head circumference in an infant. The tape should be wrapped around the head at the points just above the eyebrows, above the ears, and around the back where the head slopes up prominently from the neck.
Choice C rationale
Measuring from the chin to the top of the head is not the correct method for measuring head circumference in an infant. The measurement should be taken around the widest part of the head, which is typically above the eyebrows and ears.
Choice D rationale
Wrapping the measuring tape tightly around the neck is not the correct method for measuring head circumference in an infant. The measurement should be taken around the widest part of the head, which is typically above the eyebrows and ears.

Correct Answer is A
Explanation
Choice A rationale:
Developmental dysplasia of the hip (DDH) is a condition in which the hip joint is not properly formed or is unstable. Asymmetric thigh folds are a common finding in infants with DDH, as the affected hip may be dislocated or subluxated, leading to a difference in thigh fold appearance.
Choice B rationale:
An inwardly turned foot is not a specific indication of DDH. Instead, it may suggest other conditions, such as clubfoot or metatarsus adductus (no reference).
Choice C rationale:
Absent plantar reflexes are not associated with DDH. This finding might indicate a neurological issue or spinal cord injury (no reference).
Choice D rationale:
A lengthened thigh is not a typical finding in DDH. Instead, a shortened thigh on the affected side might be present due to the displacement of the femoral head (no reference).
Correct Answer is ["6"]
Explanation
Step 1 is to set up the equation to solve for the unknown, which is the volume in mL. The equation is (300 mg ÷ 250 mg) × 5 mL.
Step 2 is to perform the calculation: (300 mg ÷ 250 mg) × 5 mL = 6 mL. So, the nurse should administer 6 mL of amoxicillin oral solution.
