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 24-year-old female is admitted to the ER for confusion. This patient has a history of a myeloma diagnosis, constipation, intense abdominal pain, and polyuria. Based on the presenting signs and symptoms, which of the following would you most likely suspect?

• A. Diverticulosis
• B. Hypercalcemia
• C. Hypocalcemia
• D. Irritable bowel syndrome

Correct answer: B

Rationale: The correct answer is Hypercalcemia. In this case, the patient's history of myeloma, constipation, intense abdominal pain, and polyuria suggests hypercalcemia. Elevated calcium levels can lead to polyuria, severe abdominal pain, and confusion. Diverticulosis (Choice A), characterized by small pouches in the colon wall, typically does not present with confusion and polyuria. Hypocalcemia (Choice C) is unlikely given the symptoms described. Irritable bowel syndrome (Choice D) does not typically cause confusion and polyuria as seen in hypercalcemia.

3. To prepare a 56-year-old male patient with ascites for paracentesis, the nurse should?

• A. place the patient on NPO status.
• B. assist the patient to lie flat in bed.
• C. ask the patient to empty the bladder.
• D. position the patient on the right side.

Correct answer: C

Rationale: To prepare a patient with ascites for paracentesis, the nurse should ask the patient to empty the bladder. This is important to decrease the risk of bladder perforation during the procedure. The patient should be positioned in Fowler's position to facilitate the procedure, not lie flat in bed, which can compromise breathing. Placing the patient on NPO status is unnecessary as sedation is not typically required for paracentesis. Positioning the patient on the right side is not a standard preparatory measure for paracentesis.

4. How does shock typically progress?

• A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
• B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
• C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
• D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours

Correct answer: A

Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

5. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?

• A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
• B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
• C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
• D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%

Correct answer: D

Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.
