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: B

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. After 2 months of tuberculosis (TB) treatment with isoniazid (INH), rifampin (Rifadin), pyrazinamide (PZA), and ethambutol, a patient continues to have positive sputum smears for acid-fast bacilli (AFB). Which action should the nurse take next?

• A. Teach about drug-resistant TB treatment
• B. Ask the patient whether medications have been taken as directed
• C. Schedule the patient for directly observed therapy three times weekly
• D. Discuss with the healthcare provider the need for the patient to use an injectable antibiotic

Correct answer: B

Rationale: The first action should be to determine whether the patient has been compliant with drug therapy because negative sputum smears would be expected if the TB bacillus is susceptible to the medications and if the medications have been taken correctly. Assessment is the first step in the nursing process. Depending on whether the patient has been compliant or not, different medications or directly observed therapy may be indicated. The other options are interventions based on assumptions until an assessment has been completed. Teaching about drug-resistant TB treatment (Choice A) is premature without knowing the current medication compliance status. Scheduling directly observed therapy (Choice C) assumes non-compliance without confirming it first. Discussing the need for an injectable antibiotic (Choice D) is premature and not necessarily indicated without assessing the current medication adherence.

3. A patient has come into the emergency room after an injury at work in which their upper body was pinned between two pieces of equipment. The nurse notes bruising in the upper abdomen and chest. The patient is complaining of sharp chest pain, having difficulty breathing, and their trachea is deviated to the left side. Which of the following conditions are these symptoms most closely associated with?

• A. Left-sided pneumothorax
• B. Pleural effusion
• C. Atelectasis
• D. Right-sided pneumothorax

Correct answer: D

Rationale: The patient is most likely suffering from a right-sided pneumothorax. Symptoms of a pneumothorax include sharp chest pain, difficulties with breathing, decreased vocal fremitus, absent breath sounds, and tracheal shift to the opposite of the affected side. In this case, the patient's trachea is deviated to the left side, indicating a right-sided pneumothorax. Choices A, B, and C can be eliminated as they do not present with the specific symptoms described in the scenario. Left-sided pneumothorax would not cause tracheal deviation to the left side. Pleural effusion typically presents with dull chest pain and decreased breath sounds, not sharp chest pain and tracheal deviation. Atelectasis would not cause tracheal deviation and is more associated with lung collapse rather than air accumulation in the pleural space.

4. A serum potassium level of 3.2 mEq/L (3.2 mmol/L) is reported for a patient with cirrhosis who has scheduled doses of spironolactone (Aldactone) and furosemide (Lasix) due. Which action should the nurse take?

• A. Administer both drugs.
• B. Administer the spironolactone.
• C. Withhold the spironolactone and administer the furosemide.
• D. Withhold both drugs until discussed with the healthcare provider.

Correct answer: B

Rationale: A serum potassium level of 3.2 mEq/L is low (hypokalemia), which can be concerning in a patient with cirrhosis who is already at risk for electrolyte imbalances. Spironolactone is a potassium-sparing diuretic that can help increase the patient's potassium level and correct the hypokalemia. Therefore, the appropriate action for the nurse to take in this scenario is to administer the spironolactone. Withholding the spironolactone could further lower the potassium level. Furosemide, on the other hand, is a loop diuretic that can lead to potassium loss and worsen hypokalemia; hence, it should be withheld until the nurse discusses the situation with the healthcare provider. While the healthcare provider should be informed about the low potassium value, immediate administration of spironolactone is necessary to address the hypokalemia in this patient population.

5. A patient comes to the emergency department with abdominal pain. Work-up reveals the presence of a rapidly enlarging abdominal aortic aneurysm. Which of the following actions should the nurse expect?

• A. The patient will be admitted to the medicine unit for observation and medication.
• B. The patient will be admitted to the day surgery unit for sclerotherapy.
• C. The patient will be admitted to the surgical unit and resection will be scheduled.
• D. The patient will be discharged home to follow-up with his cardiologist in 24 hours.

Correct answer: C

Rationale: A rapidly enlarging abdominal aortic aneurysm is at significant risk of rupture, which can be life-threatening. The standard treatment for a rapidly enlarging abdominal aortic aneurysm is surgical intervention to prevent rupture. Therefore, the appropriate action for the nurse to expect is that the patient will be admitted to the surgical unit, and resection will be scheduled. Observation and medication (Choice A) are not sufficient for a rapidly enlarging aneurysm, and sclerotherapy (Choice B) is not typically used for aortic aneurysms. Discharging the patient home (Choice D) would be inappropriate and dangerous given the risk of rupture.
