Nursing Elites

1. Which of the following is the most common type of malignant brain tumor in the United States?

• A. Meningioma
• B. Glioblastoma multiforme
• C. Acoustic neuroma
• D. Pituitary adenoma

Correct answer: B

Rationale: Glioblastoma multiforme is the most common malignant brain tumor in the United States, accounting for a significant portion of cases. It is known for its aggressive nature and poor prognosis. Surgical resection, followed by radiation and chemotherapy, is the standard treatment approach for glioblastoma multiforme. Meningioma, acoustic neuroma, and pituitary adenoma are also types of brain tumors but are not as common as glioblastoma multiforme in the United States.

2. A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should

• A. Expose the cast to air and turn the child frequently
• B. Use a heat lamp to reduce the drying time
• C. Handle the cast with the abductor bar
• D. Turn the child as little as possible

Correct answer: A

Rationale: After applying a hip spica cast, it is important to facilitate drying by exposing the cast to air and turning the child frequently. This helps promote even drying and prevents complications such as skin breakdown. Using a heat lamp can cause burns and is not recommended. Handling the cast with the abductor bar does not aid in drying the cast. Turning the child as little as possible is incorrect as regular turning is crucial to prevent complications.

3. Following surgery to correct cryptorchidism, what is the priority action that the nurse should include in the plan of care?

• A. Prevent tension on the suture.
• B. Monitor urine for glucose and acetone.
• C. Encourage oral fluids, and monitor intake and output.
• D. Encourage coughing and deep breathing every hour.

Correct answer: A

Rationale: The correct answer is to prevent tension on the suture. After surgery for cryptorchidism, the testicle is held in position by an internal suture that should not be dislodged. Immobilization of the area for a week is crucial to prevent complications like bleeding and infection. Monitoring urine for glucose and acetone is unrelated to this surgery. While maintaining hydration is important, forcing fluids is not necessary. Encouraging coughing and deep breathing every hour may be a postoperative consideration, but it is not the priority for this specific surgery.

4. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

5. 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.
