The nurse is planning care for a family expecting their newborn to die. The nurse's interventions should be based on which statement?
- A. Tangible remembrances of the newborn (e.g., lock of hair, picture) prolong grief.
- B. Photographs of newborns should not be taken after the death has occurred.
- C. Funerals are not recommended because mother is still recovering from childbirth.
- D. Parents should be encouraged to name their newborn if they have not done so already.
Correct Answer: D
Rationale: Parents should be encouraged to name their newborn if they have not done so already because giving the baby a name can help the parents acknowledge their baby as a unique individual. It can also provide a sense of connection and identity, which can be important for the grieving process and coping with the loss. Naming the baby allows the parents to honor their child's existence and memory, and it can be a meaningful part of their healing journey.
Blood cells are formed in the:
- A. Arterioles
- B. Lymphoid tissue
- C. Bone marrow
- D. Muscle tissue
Correct Answer: C
Rationale: Blood cells are formed in the bone marrow, which is a soft tissue found in the center of most bones in the body. The process of blood cell formation is known as hematopoiesis. Bone marrow contains stem cells that can develop into different types of blood cells, including red blood cells, white blood cells, and platelets. These blood cells play essential roles in carrying oxygen, fighting infections, and assisting in blood clotting. While the other choices listed (arterioles, lymphoid tissue, and muscle tissue) have important functions in the body, blood cell formation specifically occurs primarily in the bone marrow.
The nurse is working on the pediatric floor, caring for an infant who is very fussy and has a diagnosis of DI. Which parameter should the nurse monitor while the infant is on fluid restrictions?
- A. Oral intake.
- B. Urine output.
- C. Appearance of the mucous membranes.
- D. Pulse and temperature. 116
Correct Answer: B
Rationale: In a patient with diabetes insipidus (DI) who is on fluid restrictions, monitoring urine output is crucial to assess the effectiveness of the treatment regimen. DI is a condition characterized by excessive urination and thirst due to a deficiency of antidiuretic hormone (ADH). By monitoring urine output, the nurse can determine if the restrictions are achieving the goal of decreasing urine volume and preventing dehydration. Changes in urine output can also indicate the need for adjustments in the treatment plan. Monitoring oral intake, appearance of mucous membranes, and pulse and temperature are important aspects of pediatric care but are not as directly related to managing fluid restrictions in a patient with DI.
