NCLEX RN Exam Review Answers
1. A patient is undergoing a stress test on a treadmill and turns to talk to the nurse. Which of these statements would require the most immediate intervention?
- A. I'm feeling extremely thirsty and will get some water after this.
- B. I can feel my heart racing.
- C. My shoulder and arm are hurting.
- D. My blood pressure reading is 158/80
Correct answer: C
Rationale: The correct answer is 'C: My shoulder and arm are hurting.' Unilateral arm and shoulder pain are classic symptoms of myocardial ischemia, indicating possible heart issues. In this scenario, immediate intervention is required, and the stress test should be halted. Choice A about feeling thirsty does not indicate an acute medical issue. Choice B mentioning heart racing is expected during a stress test. Choice D, a blood pressure reading of 158/80, while slightly elevated, does not present an immediate concern compared to the symptoms of arm and shoulder pain suggesting cardiac distress.
2. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?
- A. Start an IV so contrast media may be given
- B. Ensure that the patient has been NPO for at least 6 hours.
- C. Inform radiology that a radioactive glucose preparation is needed
- D. Instruct the patient to undress to the waist and remove any metal objects
Correct answer: A
Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.
3. When assessing the respiratory system of an older patient, which finding indicates that the nurse should take immediate action?
- A. Weak cough effort
- B. Barrel-shaped chest
- C. Dry mucous membranes
- D. Bilateral crackles at lung bases
Correct answer: D
Rationale: Bilateral crackles at lung bases indicate a potential acute issue like heart failure. Immediate action is necessary in this situation. The nurse should conduct further assessments such as oxygen saturation and inform the healthcare provider promptly. A barrel-shaped chest and hyperresonance to percussion are typical signs of aging and do not require immediate action. A weak cough effort is common in older patients due to age-related changes, and dry mucous membranes are also expected in older individuals. While these findings may warrant further evaluation, they do not demand immediate action like bilateral crackles at lung bases.
4. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?
- A. The bicarbonate level (HCO3) is 31 mEq/L
- B. The arterial oxygen saturation (SaO2) is 92%
- C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
- D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg
Correct answer: D
Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.
5. A patient is being treated in the Neurology Unit for Meningitis. Which of these is a priority assessment for the nurse to make?
- A. Assess the patient for nuchal rigidity
- B. Determine the patient's past exposure to infectious organisms
- C. Check the patient's WBC lab values
- D. Monitor for increased lethargy and drowsiness
Correct answer: D
Rationale: Monitoring for increased lethargy and drowsiness is crucial as these symptoms indicate a decreased level of consciousness, which is the cardinal sign of increased Intracranial Pressure (ICP). Elevated ICP can lead to serious complications and requires immediate intervention. Assessing for nuchal rigidity is important in suspected cases of meningitis but monitoring lethargy and drowsiness takes precedence due to its direct correlation with ICP. Determining past exposure to infectious organisms and checking WBC lab values are important for diagnosing and treating meningitis but do not directly address the immediate concern of increased ICP.
