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

Understanding the cause of illness is a complex cognitive task that typically develops later in childhood. Preschool-aged children are still developing their understanding of cause and effect, and their thinking is often more concrete than abstract.

Choice B rationale

Describing manifestations of illness is also a complex task that requires a certain level of cognitive and language development. While preschool-aged children are developing their language skills rapidly, their ability to describe complex phenomena such as the manifestations of illness is still developing.

Choice C rationale

Awareness of body functioning is a concept that typically develops later in childhood. Preschool-aged children are still learning about their bodies and how they work. Their understanding of body functioning is often concrete and based on what they can see and feel.

Choice D rationale

Relating fears to magical thinking is a characteristic of preschool-aged children’s cognitive development. At this age, children’s thinking is often dominated by fantasy and magic. They may attribute events or experiences to magical causes, and their fears may be related to these magical beliefs.

Choice A rationale

The American Academy of Pediatrics and the Dietary Guidelines for Americans recommend that children be introduced to foods other than breast milk or infant formula when they are about 6 months old. The first foods to be introduced should be single-ingredient foods that contain no sugar or salt. Among the first foods to be introduced are infant cereals. Iron-fortified cereals are particularly important because iron is a crucial nutrient in the second half of a baby’s first year.

Choice B rationale

While strained fruits are a common food to introduce early on, they are typically not the first food to be introduced. The first food is usually an iron-fortified cereal due to the importance of iron in a baby’s diet.

Choice C rationale

Pureed meats are also a good source of iron and can be introduced early on. However, they are not typically the first food to be introduced.

Choice D rationale

Cooked egg whites are not typically one of the first foods introduced to infants. There is also a risk of allergic reactions with egg whites, so they should be introduced with caution and not as the first food.
