Which of the ff is the characteristic of a ketogenic diet that is suggested for children with seizures?
- A. High carbohydrate diet
- B. High fat diet
- C. High protein diet
- D. Low fat diet
Correct Answer: B
Rationale: The characteristic of a ketogenic diet that is suggested for children with seizures is a high-fat diet. Ketogenic diet is a specialized high-fat, low-carbohydrate diet that helps to control seizures in some children with epilepsy, especially those who do not respond well to medication. The high fat content in the diet leads to the production of ketones, which are believed to reduce seizure activity in the brain. Therefore, a high-fat diet is a key aspect of the ketogenic diet for managing seizures in children.
Which of the following would be the most appropriate nursing intervention when caring for a client with a fractured rib?
- A. Apply immobilization device after examination by physician
- B. Discourage taking deep breaths if breathing is painful
- C. Advise against using analgesics and regional nerve blocks
- D. Encouraged increased fluid intake if pulmonary contusion exists
Correct Answer: A
Rationale: Applying an immobilization device, such as a rib belt or rib binder, is a common nursing intervention for a client with a fractured rib. However, it is essential to first ensure that the client is examined by a physician to confirm the diagnosis and assess the severity of the fracture. Immobilizing the area helps reduce pain, support the chest wall, and promote healing by limiting movement that can further irritate the injured rib. Additionally, the physician's assessment is crucial for determining the appropriate treatment plan and ruling out any complications that may require further medical intervention.

The clinical manifestations of Parkinson's disease (bradykinesia rigidity and tremors) is directly related to a decreased level of:
- A. Acetylcholine
- B. Serotonin
- C. Dopamine
- D. Phenylalanine
Correct Answer: C
Rationale: The clinical manifestations of Parkinson's disease, including bradykinesia, rigidity, and tremors, are directly related to a decreased level of dopamine in the brain. Dopamine is a neurotransmitter that plays a crucial role in regulating movement and coordination. A decrease in dopamine levels results in the characteristic motor symptoms observed in Parkinson's disease. The treatment for Parkinson's disease often involves medications that help increase dopamine levels in the brain, such as levodopa, to alleviate these symptoms.
A patient, who had a hysterectomy 2 days ago, reports tenderness in her left calf. The nursing assessment reveals the following: left calf 17.5", right calf 14", left thigh 32", right thigh 28", and a shiny, warm, and reddened left leg. Which of the following interventions should be given priority in the patient's plan of care? i. Maintain bedrest ii. Encourage ambulation TID iii. Apply bilateral antiembolism v. Apply right antiembolism stockings stockings vi. Apply warm moist heat as ordered iv. Encourage bilateral leg exercises
- A. 3 and 4 c.2, 3 , 4 and 5
- B. 1, 5 and 6
- C. 1, 2, 3, 5 and 6
Correct Answer: A
Rationale: The patient's symptoms and assessment findings suggest the presence of deep vein thrombosis (DVT), which is a potential complication following surgery such as a hysterectomy. The priority interventions in this case should focus on preventing the progression of DVT and reducing the risk of pulmonary embolism.
