Which of these diseases can be prevented with a vaccine for humans?
- A. eastern equine encephalitis
- B. western equine encephalitis
- C. West Nile encephalitis
- D. Japanese encephalitis
Correct Answer: D
Rationale: Step 1: Identify the disease - Japanese encephalitis is caused by a virus transmitted by mosquitoes.
Step 2: Understand the role of a vaccine - a vaccine stimulates the immune system to produce antibodies to fight the virus.
Step 3: Vaccines prevent future infections - by administering a vaccine for Japanese encephalitis, individuals can develop immunity and prevent the disease.
Step 4: Therefore, the correct answer is D because a vaccine is available to prevent Japanese encephalitis.
Summary: A, B, and C are incorrect because there are no vaccines available for eastern equine encephalitis, western equine encephalitis, and West Nile encephalitis, respectively.
Laboratory findings that the nurse would expect to be present in the patient with RA include
- A. polycythemia.
- B. increased immunoglobulin G (IgG).
- C. decreased white blood cell (WBC) count.
- D. anti-citrullinated protein antibody (ACPA).
Correct Answer: D
Rationale: ACPA is specific to RA.
Dopamine is an important neurotransmitter. Which disease or disorder results when the neurons in the brain that produce dopamine die?
- A. Multiple sclerosis
- B. Lou Gehrig disease (amyotrophic lateral sclerosis)
- C. Parkinson disease
- D. Seizure disorder
Correct Answer: C
Rationale: Parkinson disease is caused by the degeneration of dopamine-producing neurons in the brain, leading to motor symptoms such as tremors and rigidity. Multiple sclerosis and ALS involve different neurological mechanisms, while seizure disorders are related to abnormal electrical activity in the brain. Dopamine's role in motor control is critical to understanding Parkinson disease.
KL is a 34-year-old male admitted to the hospital (large trauma center) after suffering a traumatic brain injury (TBI) secondary to a serious motor vehicle accident. He was in excellent health prior to the accident. HT: 6'2" WT: 190 pounds (86 kg) What level of energy intake per day is the most appropriate for KL?
- A. 1,800 kcal
- B. 2,100 kcal
- C. 2,400 kcal
- D. 2,700 kcal
Correct Answer: C
Rationale: For a patient with traumatic brain injury (TBI), an energy intake of approximately 2,400 kcal/day is often appropriate to meet increased metabolic demands while avoiding overfeeding, which can exacerbate complications like hyperglycemia or respiratory issues.
A 30-year-old female presents with muscle weakness in the lower extremities and palpitations. Her symptoms have been progressively worse over the course of a 2 weeks. She reports to be in great health, but had a period of abdominal pain and diarrhea approximately 5 weeks ago. Her temperature is 98.9 deg F (37.2 deg C), blood pressure 117/82 mmHg, pulse is 102/min, and respirations are 16/min. On physical exam, there is 4-/5 muscle strength throughout the lower extremities. Bilateral patellar reflexes are 1+ and ankle reflexes are absent. Lumbar puncture was performed, and results are pending. Part 2: What is the most appropriate initial treatment?
- A. High dose corticosteroids
- B. Intravenous immunoglobulin
- C. Potassium chloride
- D. Pyridostigmine
Correct Answer: B
Rationale: Intravenous immunoglobulin (IVIG) is the first-line treatment for Guillain-Barre syndrome (GBS). It works by modulating the immune response and reducing the severity of the disease. High-dose corticosteroids are not effective in GBS, and potassium chloride and pyridostigmine are not indicated for this condition.
