A nurse in calculating the estimated date of birth using Nägele's rule for a client who is pregnant and whose last menstrual cycle started june 21. Which of the following is the estimated date of delivery in the next year?

A. Subcutaneous in the left vastus lateralis: Phytonadione is usually administered IM, not subcutaneously. The vastus lateralis muscle in the thigh is a common site for IM injections in newborns.

B. IM in the right deltoid: The deltoid muscle in the upper arm is not typically the recommended site for administering medications to newborns. The vastus lateralis muscle in the thigh is preferred for newborn IM injections due to better muscle development and blood flow.

C. IM in the left vastus lateralis: This is the correct option. Phytonadione, or Vitamin K, is routinely given to newborns to prevent vitamin K deficiency bleeding (VKDB). It's administered as an IM injection into the vastus lateralis muscle in the thigh, which is a standard practice for newborn vitamin K administration.

D. Subcutaneous in the right deltoid: Subcutaneous administration in the deltoid is not typically used for newborns, especially for medications like phytonadione that are commonly administered IM.

A. Fortified soy milk: Fortified soy milk is a good source of vitamin B12, which is important, especially for individuals following a vegan diet. Vitamin B12 is primarily found in animal products, so those on a vegan diet need to obtain it through fortified foods or supplements.

B. Brown rice: Brown rice is not a significant source of vitamin B12. While it contains other B vitamins, it lacks B12, which is vital for neurological health and the production of red blood cells.

C. Raw carrots: Carrots do not contain vitamin B12. They are rich in beta-carotene (a precursor to vitamin A) and provide other vitamins and minerals, but they are not a source of B12.

D. Fresh citrus fruits: Citrus fruits, like oranges and grapefruits, are good sources of vitamin C, but they do not contain vitamin B12. Vitamin C is important for the absorption of non-heme iron, which is found in plant-based foods, but it does not provide B12.
