A school-age child is admitted to the hospital with acute glomerulonephritis and oliguria. Which dietary menu items should be allowed for this child? (Select all that apply.)
- A. Apples
- B. Bananas
- C. Cheese
- D. Carrot sticks
Correct Answer: A
Rationale: Apples, bananas, and strawberries are all suitable choices for a child with acute glomerulonephritis and oliguria. These fruits are high in water content and are not typically restricted in the diet of a child with this condition. It is important to provide hydration through food sources for a child experiencing oliguria. However, foods high in sodium, potassium, and protein (such as cheese) may need to be limited or modified based on the child's condition and the doctor's recommendations. Carrot sticks, although generally a healthy choice, may have high potassium content which could be restricted based on the child's individual dietary requirements.
An elderly patient, Mr. Cruz is being cared for by nurse Bennie because of pulmonary embolism. Nurse Bennie would anticipate an order for immediate administration of:
- A. warfarin
- B. heparin
- C. dexamethazone
- D. protamine sulfate
Correct Answer: B
Rationale: In the scenario of an elderly patient like Mr. Cruz with suspected pulmonary embolism, the nurse would anticipate an order for the immediate administration of heparin. Heparin is an anticoagulant medication that works quickly to prevent the further development of blood clots. It is often used as the initial treatment for pulmonary embolism to prevent existing blood clots from getting larger and reduce the risk of new clots forming. Heparin is preferred over warfarin initially because it has a more rapid onset of action. Warfarin, which is a commonly used anticoagulant for longer-term management, takes several days to reach its full effect and requires monitoring of the prothrombin time (INR). Therefore, in Mr. Cruz's acute situation, heparin would be the most appropriate choice for immediate intervention to address the pulmonary embolism.
