Nursing Elites

1. A patient is being admitted to the ICU with a severe case of encephalitis. Which of these drugs would the nurse not expect to be prescribed for this condition?

• A. Acyclovir (Zovirax)
• B. Mannitol (Osmitrol)
• C. Lactated Ringer's
• D. Phenytoin (Dilantin)

Correct answer: C

Rationale: In the treatment of encephalitis, medications like Acyclovir and Phenytoin are commonly prescribed. Acyclovir is an antiviral medication used to treat viral infections like herpes simplex virus, which can cause encephalitis. Phenytoin is an antiepileptic drug that may be used to manage seizures associated with encephalitis. Mannitol is a diuretic used to reduce intracranial pressure (ICP) by decreasing cerebral edema. Lactated Ringer's solution, on the other hand, is primarily used in fluid replacement therapy and may not be indicated if a patient is at risk for high ICP, as excessive fluid administration could worsen cerebral edema and increase ICP.

2. Which of the following conditions most commonly causes acute glomerulonephritis?

• A. A congenital condition leading to renal dysfunction.
• B. Prior infection with group A Streptococcus within the past 10-14 days.
• C. Viral infection of the glomeruli.
• D. Nephrotic syndrome.

Correct answer: B

Rationale: Acute glomerulonephritis is most commonly caused by the immune response to a prior upper respiratory infection with group A Streptococcus. Glomerular inflammation occurs about 10-14 days after the infection, resulting in scant, dark urine and retention of body fluid. Periorbital edema and hypertension are common signs at diagnosis.

3. A patient has a history of photosensitive reactions to medications. Which of the following drugs is associated with photosensitive reactions? Select one that doesn't apply

• A. Ciprofloxacin (Cipro)
• B. Sulfonamide
• C. Norfloxacin (Noroxin)
• D. Nitro-Dur patch

Correct answer: D

Rationale: Nitro-Dur patch is not associated with photosensitive reactions. It is used to prevent chest pain or angina, and common side effects include headache, lightheadedness, nausea, and flushing. Choices A, B, and C are known to cause photosensitive reactions. Ciprofloxacin (Cipro), Sulfonamides, and Norfloxacin (Noroxin) are drugs that are commonly associated with photosensitivity reactions. Patients taking these medications should be advised to avoid direct sunlight and use sun protection to prevent skin reactions.

4. The health care provider writes an order for bacteriologic testing for a patient who has a positive tuberculosis skin test. Which action should the nurse take?

• A. Teach about the reason for the blood tests.
• B. Schedule an appointment for a chest x-ray.
• C. Teach about the need to get sputum specimens for 2 to 3 consecutive days.
• D. Instruct the patient to expectorate three specimens as soon as possible.

Correct answer: C

Rationale: The correct action for the nurse to take is to teach the patient about the need to collect sputum specimens for 2 to 3 consecutive days for bacteriologic testing for M. tuberculosis. It is important to obtain these specimens on different days rather than all at once. Blood tests are not used for tuberculosis testing, so teaching about blood tests is not relevant. While a chest x-ray is important in tuberculosis diagnosis, it is not a bacteriologic test. The appearance on a chest x-ray alone is not sufficient to diagnose TB as other diseases can have similar findings.

5. Which action will the nurse include in the plan of care for a patient who has been diagnosed with chronic hepatitis B?

• A. Advise limiting alcohol intake to 1 drink daily
• B. Schedule for liver cancer screening every 6 months
• C. Initiate administration of the hepatitis C vaccine series
• D. Monitor anti-hepatitis B surface antigen (anti-HBs) levels annually

Correct answer: B

Rationale: Patients diagnosed with chronic hepatitis B are at a higher risk for developing liver cancer. Therefore, it is essential to schedule them for liver cancer screening every 6 to 12 months to detect any potential malignancies at an early stage. Advising patients to limit alcohol intake is crucial as alcohol can exacerbate liver damage; thus, patients with chronic hepatitis B are advised to completely avoid alcohol. Administering the hepatitis C vaccine is irrelevant for a patient diagnosed with chronic hepatitis B since it is a different virus. Monitoring anti-hepatitis B surface antigen (anti-HBs) levels annually is not necessary as the presence of anti-HBs indicates a past hepatitis B infection or vaccination, and it does not require regular monitoring.
