During a well-baby visit, Liza asks the nurse when she should start giving her infant solid foods. The nurse should instruct her to introduce which solid food first?
- A. Applesauce
- B. Egg whites
- C. Rice cereal
- D. Yogurt
Correct Answer: C
Rationale: When introducing solid foods to an infant for the first time, rice cereal is generally recommended as it is mild, easy to digest, and less likely to cause food allergies compared to other foods. It is a good source of iron and a suitable first food for most infants. Introducing rice cereal as the first solid food also helps the baby get accustomed to a different texture and aids in their transition from a milk-only diet to solid foods. It is important to follow the guidance of healthcare professionals regarding the introduction of solid foods to infants to ensure they receive appropriate nutrition and avoid any potential digestive issues.

After being in remission from Hodgkin's disease for 18 months, a client develops a fever of unknown origin. The physician orders a blind liver biopsy to rule out advancing Hodgkin'sdisease and infection. Twenty-four hours after the biopsy, the client has a fever, complains of severe abdominal pain, and seems increasingly confused. The nurse suspects that these finding result from:
- A. Bleeding in the liver caused by the liver biopsy.
- B. Perforation of the colon caused by the liver biopsy.
- C. An allergic reaction to the contrast media used during liver biopsy.
- D. Normal post procedural pain, with a change in the level of consciousness resulting from the preexisting fever.
Correct Answer: A
Rationale: The symptoms of fever, severe abdominal pain, and increasing confusion following a liver biopsy are indicative of a potential complication such as bleeding in the liver caused by the biopsy. Hepatic bleeding can lead to abdominal pain and can cause a change in the level of consciousness. These symptoms should prompt immediate medical attention to address the bleeding and prevent further complications. Perforation of the colon, an allergic reaction to contrast media, or normal post-procedural pain would not typically present with these specific symptoms in this context.
