NCLEX RN Exam Review Answers

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

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 patient asks the nurse whether he is a good candidate to use a CPAP machine. The nurse reviews the client's history. Which condition would contraindicate the use of a CPAP machine?

Correct answer: A

Rationale: The correct answer is that the patient is in the late stage of dementia. In late-stage dementia, individuals may have an inability to follow commands and understand instructions independently, which are essential for proper installation and use of a CPAP machine. This makes using a CPAP machine challenging and potentially ineffective for patients in this condition. Choice B, having a history of bronchitis, does not contraindicate the use of a CPAP machine. In fact, CPAP therapy can be beneficial for patients with respiratory conditions like bronchitis. Choice C, a history of suicidal gestures/attempts, while concerning for the patient's mental health, does not directly contraindicate the use of a CPAP machine. Choice D, being on beta-blockers, is not a contraindication for CPAP machine use. Beta-blockers are commonly used medications for various conditions and do not interfere with the use of a CPAP machine.

3. When assessing a patient suspected to have Hepatitis, a nurse notes the patient's eyes are yellow-tinged. Which of the following diagnostic results would further assist in confirming this diagnosis?

Correct answer: B

Rationale: Elevated serum ALT levels would further confirm the diagnosis of Hepatitis. ALT is a liver enzyme, and hepatitis is a liver disease. Elevated liver enzymes, such as ALT, often indicate liver damage. Choice A, 'Decreased serum Bilirubin,' is incorrect as elevated bilirubin levels are typically seen in hepatitis due to impaired bilirubin metabolism. Choices C and D are unrelated to confirming a diagnosis of hepatitis as they describe findings not specific to liver function or hepatitis. Low RBC and Hemoglobin with increased WBCs (Choice C) suggest a different condition like anemia or infection, not specific to liver disease. Increased Blood Urea Nitrogen level (Choice D) is more indicative of kidney function rather than liver function, thus not helpful in confirming hepatitis.

4. A patient with acute shortness of breath is admitted to the hospital. Which action should the nurse take during the initial assessment of the patient?

Correct answer: B

Rationale: When a patient presents with acute shortness of breath, the initial assessment should focus on gathering specific information relevant to the current episode of respiratory distress. A comprehensive health history or full physical examination can be deferred until the acute distress has been addressed. Asking specific questions helps determine the cause of the distress and guides appropriate treatment. While checking for allergies is important, completing the entire admission database is not a priority during the initial assessment. Likewise, delaying the physical assessment for pulmonary function tests is not recommended as the immediate focus should be on addressing the acute respiratory distress before ordering further diagnostic tests or interventions.

5. The mother of a child with hepatitis A tells the home care nurse that she is concerned because the child's jaundice seems worse. What is the nurse's best response?

Correct answer: C

Rationale: The best response for the nurse in this situation is to explain to the mother that jaundice may seem to worsen before it eventually gets better. This is a common occurrence in hepatitis A. Option A about changing the child's diet is irrelevant to the concern raised by the mother and not supported by evidence. Option B suggesting the child is infectious again is incorrect and may cause unnecessary alarm as jaundice does not indicate reinfection. Option D, advising the mother to call the primary health care provider, is premature as the nurse can first provide education and reassurance regarding the expected course of jaundice in hepatitis A.
