NCLEX RN Exam Review Answers
1. The nurse assesses a patient suspected of having meningitis. Which of the following is a common clinical manifestation of this condition?
- A. A high WBC count and decreased level of consciousness
- B. A high WBC count and manic activity
- C. A low WBC count and manic activity
- D. A low WBC count and decreased level of consciousness
Correct answer: A
Rationale: The correct answer is 'A high WBC count and decreased level of consciousness.' Meningitis is often caused by an infectious organism, leading to an increase in Intracranial Pressure (ICP), which can result in decreased level of consciousness. While meningitis can trigger an inflammatory response, it typically presents with an elevated white blood cell (WBC) count rather than a low WBC count. Manic activity is not a common clinical manifestation of meningitis; instead, patients may exhibit altered mental status, confusion, or lethargy.
2. The patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving epoprostenol (Flolan). Which assessment information requires the most immediate action by the nurse?
- A. The oxygen saturation is 94%.
- B. The blood pressure is 98/56 mm Hg.
- C. The patient's central IV line is disconnected.
- D. The international normalized ratio (INR) is prolonged.
Correct answer: C
Rationale: The most immediate action required by the nurse is to address the disconnected central IV line delivering epoprostenol (Flolan). Epoprostenol has a short half-life of 6 minutes, necessitating immediate reconnection to prevent rapid clinical deterioration. While oxygen saturation, blood pressure, and INR are important parameters requiring monitoring and intervention, the priority lies in ensuring the continuous delivery of the critical medication to stabilize the patient's condition.
3. Which factors will the nurse consider when calculating the CURB-65 score for a patient with pneumonia? (Select one that does not apply)
- A. Age
- B. Blood pressure
- C. Respiratory rate
- D. Oxygen saturation
Correct answer: D
Rationale: The correct answer is 'Oxygen saturation.' When calculating the CURB-65 score for a patient with pneumonia, the factors considered include mental status (confusion), BUN (elevated), blood pressure (decreased), respiratory rate (increased), and age (65 and older). Oxygen saturation is not used in the CURB-65 scoring system. While blood pressure, respiratory rate, and age are factors that are used in the calculation of the CURB-65 score, oxygen saturation is not part of the scoring criteria. Therefore, oxygen saturation is the factor that does not apply when calculating the CURB-65 score.
4. An older patient is receiving standard multidrug therapy for tuberculosis (TB). The nurse should notify the health care provider if the patient exhibits which finding?
- A. Yellow-tinged skin
- B. Orange-colored sputum
- C. Thickening of the fingernails
- D. Difficulty hearing high-pitched voices
Correct answer: A
Rationale: The correct answer is 'Yellow-tinged skin.' Yellow-tinged skin is indicative of noninfectious hepatitis, a toxic effect of isoniazid (INH), rifampin, and pyrazinamide. If a patient on TB therapy develops hepatotoxicity, alternative medications will be necessary. Thickening of fingernails and difficulty hearing high-pitched voices are not typical side effects of the medications used in standard TB therapy. Presbycusis, age-related hearing loss, is common in older adults and not a cause for immediate concern. Orange-colored sputum is an expected side effect of rifampin and does not warrant immediate notification to the healthcare provider.
5. What is the cause of meningitis that is fatal in half of the infected patients?
- A. Virus
- B. Bacteria
- C. Fungus
- D. Noninfectious agent
Correct answer: B
Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.
