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. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

3. A patient with a cast on the right leg is being cared for by a nurse. Which of the following assessment findings would be most concerning for the nurse?

• A. The capillary refill time is 2 seconds
• B. The patient complains of itching and discomfort
• C. The cast has a foul-smelling odor
• D. The patient is on antibiotics

Correct answer: C

Rationale: A foul-smelling odor emanating from the cast is a concerning finding as it indicates the possibility of infection or the presence of a pressure ulcer. These conditions can lead to serious complications if not promptly addressed. It is crucial for the nurse to investigate further and take appropriate actions to prevent potential harm to the patient. The other options do not directly indicate a risk of infection or complications associated with the cast. Itching and discomfort are common complaints due to wearing a cast, and the patient being on antibiotics may be part of their treatment plan for an unrelated condition. Capillary refill time of 2 seconds is within the normal range and would not be a cause for immediate concern in this scenario.

4. An 80-year-old patient is admitted with dyspnea, dependent edema, rales, and distended neck veins. As the nurse monitors the patient, he becomes increasingly short of breath and begins to have cardiac dysrhythmias. The most critical intervention for this patient is to:

• A. Ensure his airway is open and unobstructed.
• B. Apply oxygen to maintain his oxygen saturation above 94%.
• C. Administer Dobutamine to increase cardiac output.
• D. Start an IV for monitoring fluid intake.

Correct answer: A

Rationale: In a patient presenting with dyspnea, dependent edema, rales, distended neck veins, and developing cardiac dysrhythmias, the priority intervention is to ensure the airway is open and unobstructed. Maintaining an open airway is crucial for adequate ventilation and oxygenation, especially in a patient showing signs of impending respiratory distress and cardiac compromise. While applying oxygen to maintain oxygen saturation is important, ensuring airway patency takes precedence as it directly impacts the patient's ability to breathe. Administering Dobutamine may be necessary to improve cardiac output; however, addressing the airway first is essential to prevent further respiratory distress and worsening dysrhythmias. Starting an IV for monitoring fluid intake is not the most critical intervention in this scenario compared to ensuring airway patency and oxygenation.

5. The nurse is caring for a newborn infant after surgical intervention for imperforate anus. The nurse should place the infant in which position in the postoperative period?

• A. Supine with no head elevation
• B. Side-lying with the legs flexed
• C. Side-lying with the legs extended
• D. Supine with the head elevated 30 degrees

Correct answer: B

Rationale: After surgical intervention for imperforate anus, the infant should be placed in a side-lying position with the legs flexed. This position helps reduce edema and pressure on the surgical site, preventing strain and promoting comfort. Placing the infant supine with no head elevation (Choice A) doesn't offer adequate support and may increase pressure on the area. Side-lying with the legs extended (Choice C) doesn't help reduce edema and pressure effectively. Placing the infant supine with the head elevated 30 degrees (Choice D) isn't recommended as it may not provide adequate support and comfort needed for recovery.
