The nurse is instructing a parent of a newborn on the foods that are to be started based on age. The nurse instructs the parent that the first food given to a newborn is rice cereal. What statement by the parent suggests appropriate understanding of the next food that can be introduced?

Correct Answer: C

Rationale: The correct answer is C: Fruits should be given next. This is because after introducing rice cereal, the next recommended food for infants is usually fruits. Fruits are easily digestible and provide essential nutrients. Chicken and eggs are common allergenic foods and are usually introduced later. Whole milk is not recommended until after the first year of life due to its high protein and mineral content, which can strain the infant's kidneys. Thus, choosing fruits as the next food to introduce shows an appropriate understanding of the recommended feeding progression for infants.

Correct Answer: D

Rationale: Correct Answer: D - Increased calories Rationale: 1. Infants with CHF have increased metabolic demands due to their heart working harder. 2. Increased caloric intake helps meet the energy needs for the heart and body. 3. Adequate calories promote growth and development in infants with CHF. Summary of other choices: A. Decreased fat: Fat provides essential fatty acids and energy, important for growth and development. Decreasing fat may lead to inadequate energy intake. B. Increased fluids: While fluid restriction may be necessary in some cases of CHF, it is not a primary need. Fluid management is crucial but not the main focus in this scenario. C. Decreased protein: Protein is essential for growth, repair, and immune function. Decreasing protein may lead to muscle wasting and compromised immune function.

Correct Answer: B

Rationale: The correct initial intervention is to notify the practitioner of the child's increased apprehension, tachycardia, and increased chest tube drainage. This is important because these signs could indicate a potential complication post-heart surgery that requires immediate medical attention. Applying warming blankets (choice A) may not address the underlying issue, giving additional pain medication (choice C) without practitioner approval could mask symptoms, and encouraging coughing and deep breathing (choice D) may not be appropriate in this situation. It is crucial to involve the practitioner promptly for further evaluation and management.

Correct Answer: A

Rationale: The correct answer is A: Osteoporosis. Immobility leads to decreased weight-bearing stress on bones, causing bone demineralization and increased risk of osteoporosis. Osteoporosis is characterized by decreased bone density and increased fracture risk. Pooling of blood (B) is more related to circulatory issues. Urinary retention (C) is a result of bladder dysfunction. Susceptibility to infection (D) is not directly related to bone demineralization from immobility.

Correct Answer: B

Rationale: Correct Answer: B (erythroid progenitor: megakaryocyte) Rationale: Erythroid progenitors differentiate into red blood cells, not megakaryocytes. Megakaryocytes arise from megakaryocyte-erythroid progenitors. The mismatch lies in the differentiation pathway. Summary: A: Monocyte progenitor differentiates into macrophages. C: Myeloid progenitor gives rise to neutrophils. D: Lymphoid progenitor differentiates into natural killer cells.
