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. In a pediatric clinic, a nurse is assessing a child recently diagnosed with cystic fibrosis. Which of the following later findings of this disease would the nurse not expect to see at this time?

• A. Positive sweat test
• B. Bulky greasy stools
• C. Moist, productive cough
• D. Meconium ileus

Correct answer: C

Rationale: In a child newly diagnosed with cystic fibrosis (CF), noisy respirations and a dry, non-productive cough are typically the first respiratory signs to appear. The other options, including a positive sweat test, bulky greasy stools, and meconium ileus, are among the earliest findings of CF. CF is a genetic condition that affects the production of mucus, sweat, saliva, and digestive juices. Due to a defective gene, these secretions become thick and sticky instead of thin and slippery, leading to blockages in various passageways, especially in the pancreas and lungs. Respiratory failure is a severe consequence of CF, making it crucial to monitor respiratory symptoms closely in affected individuals. Therefore, a moist, productive cough would not be an expected finding in a newly diagnosed child with CF.

3. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?

• A. The patient is allergic to shellfish.
• B. The patient has a pacemaker.
• C. The patient suffers from claustrophobia.
• D. The patient takes antipsychotic medication.

Correct answer: B

Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.

4. The nurse is taking the health history of a patient being treated for Emphysema and Chronic Bronchitis. After being told the patient has been smoking cigarettes for 30 years, the nurse expects to note which assessment finding?

• A. Increase in Forced Vital Capacity (FVC)
• B. A widened chest cavity
• C. Clubbed fingers
• D. An increased risk of cardiac failure

Correct answer: C

Rationale: 1. Increase in Forced Vital Capacity (FVC): Forced Vital Capacity is the volume of air exhaled from full inhalation to full exhalation. A patient with COPD would have a decrease in FVC. Therefore, this choice is incorrect. 2. A widened chest cavity: A patient with COPD often presents with a 'barrel chest,' which is seen as a widened chest cavity. Hence, a narrowed chest cavity is not an expected finding. 3. Clubbed fingers - CORRECT: Clubbed fingers are a sign of a long-term, or chronic, decrease in oxygen levels, which is commonly seen in patients with chronic respiratory conditions like Emphysema and Chronic Bronchitis. 4. An increased risk of cardiac failure: Although a patient with these conditions would indeed be at an increased risk for cardiac failure, this is a potential complication and not an assessment finding, making it an incorrect choice.

5. A patient with right lower-lobe pneumonia has been treated with IV antibiotics for 3 days. Which assessment data obtained by the nurse indicates that the treatment has been effective?

• A. Bronchial breath sounds are heard at the right base.
• B. The patient coughs up small amounts of green mucus.
• C. The patients white blood cell (WBC) count is 9000/L
• D. Increased tactile fremitus is palpable over the right chest

Correct answer: C

Rationale: The normal WBC count indicates that the antibiotics have been effective. All the other data suggest that a change in treatment is needed.
