- A. New parents need time to learn how to hold the newborn.
- B. The umbilical cord needs time to separate.
- C. Newborn skin is easily traumatized by washing.
- D. The chance of chilling the newborn outweighs the benefits of bathing.

- C. Clean the commode after each bowel movement.
- D. Boil water prior to drinking and place open containers in the refrigerator.

- B. Dresses in extra layers of clothing
- C. Applies a heating pad to her feet

Goal setting for a client with Meniere's disease should include which of the following?
- A. Frequent ambulation
- B. Prevention of a fall injury
- C. Consumption of three meals per day
- D. Prevention of infection
Correct Answer: B
Rationale: Although not contraindicated, initially ambulation may be difficult because of vertigo and is recommended only with assistance. Vertigo resulting in balance problems is one of the most common manifestations of Meniere's disease. Adequate nutrition is important, but the emphasis in Meniere's disease is not the number of meals per day but a decrease in intake of sodium. Infection is not an anticipated problem.
