1. What is the cause of meningitis that is fatal in half of the infected patients?

• A. Virus
• B. Bacteria
• C. Fungus
• D. Noninfectious agent

Correct answer: Bacteria

Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.

2. A 28-year-old male has been found wandering around in a confusing pattern. The male is sweaty and pale. Which of the following tests is most likely to be performed first?

• A. Blood sugar check
• B. CT scan
• C. Blood cultures
• D. Arterial blood gases

Correct answer: Blood sugar check

Rationale: In a 28-year-old male presenting with confusion, sweating, and pallor, the most likely cause is hypoglycemia, especially with no mention of trauma or infection. Therefore, the initial test to be performed should be a blood sugar check to rule out low blood sugar levels. Checking blood sugar levels is crucial in such a scenario as hypoglycemia can lead to altered mental status. A CT scan (choice B) is not typically the initial test for altered mental status without any focal neurological signs or head trauma. Blood cultures (choice C) are more relevant in cases suspected of infection, which is not a primary concern in this scenario. Arterial blood gases (choice D) may be considered later if there are concerns about respiratory status or acid-base disturbances, but in this case, checking the blood sugar level is the most immediate and appropriate action.

3. The nurse is caring for a 10-year-old upon admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: Urinary output of 30 ml per hour

Rationale: The correct answer is urinary output of 30 ml per hour. In a 10-year-old child, this level of urinary output is indicative of adequate fluid replacement without suggesting overload. Monitoring urinary output is crucial in assessing fluid balance. Choices B, C, and D are incorrect. No complaints of thirst do not provide a direct assessment of fluid status. Increased hematocrit is a sign of dehydration, not adequate fluid replacement. Good skin turgor around the burn is a general assessment but may not directly reflect the child's overall fluid status.

4. To detect possible complications in a patient with severe cirrhosis who has bleeding esophageal varices, it is most important for the nurse to monitor

• A. bilirubin levels.
• B. ammonia levels.
• C. potassium levels.
• D. prothrombin time.

Correct answer: ammonia levels.

Rationale: In a patient with severe cirrhosis and bleeding esophageal varices, monitoring ammonia levels is crucial. Severe liver dysfunction impairs the metabolism of protein in the GI tract, leading to increased ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Monitoring bilirubin levels is important for assessing liver function and jaundice but may not directly reflect the risk of complications from bleeding esophageal varices. Potassium levels are important but not the most critical in this scenario. Prothrombin time is essential for evaluating coagulation status but does not directly relate to the risk of complications from bleeding esophageal varices in this patient.

5. Which of the following patients is at the greatest risk for a stroke?

• A. A 60-year-old male who weighs 270 pounds, has atrial fibrillation, and has had a TIA in the past
• B. A 75-year-old male who has frequent migraines, drinks a glass of wine every day, and is Hispanic
• C. A 40-year-old female who has high cholesterol and uses oral contraceptives
• D. A 65-year-old female who is African American, has sickle cell disease, and smokes cigarettes

Correct answer: A 60-year-old male who weighs 270 pounds, has atrial fibrillation, and has had a TIA in the past

Rationale: The correct answer is the 60-year-old male who has a combination of significant risk factors for stroke, including atrial fibrillation, a history of a transient ischemic attack (TIA), and obesity. These factors greatly increase his risk of stroke. While other choices may have some individual risk factors, they do not collectively pose as high a risk as the patient described in option A. Option B includes migraines and alcohol consumption but lacks other major risk factors seen in option A. Option C mentions high cholesterol and oral contraceptives, which are risk factors but not as significant as atrial fibrillation and a prior TIA. Option D includes smoking and sickle cell disease but lacks the crucial risk factors present in option A.
