A nurse is preparing to administer vitamin K 1mg IM to a newborn.

The available vitamin K injection is 1 mg/0.5 mL. How many mL should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale

While facial paralysis is a serious condition, it is not typically associated with a cleft palate.

Choice B rationale

Ear infections are a common complication of a cleft palate, but they are not typically a sign of an immediate, serious problem.

Choice C rationale

Increased intracranial pressure is not a common complication of a cleft palate, but it is a serious condition that requires immediate medical attention.

Choice D rationale

Drooling is common in children with a cleft palate and is not typically a sign of a serious problem.

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).
