NCLEX RN Exam Review Answers
1. A nurse is caring for a client who was recently diagnosed with breast cancer. The oncologist uses the TNM staging system to classify this case as T2, N2, M0. The nurse understands that TNM stands for:
- A. Tumor, Necrosis, Metastasis
- B. Tumor, Node Involvement, Mastectomy
- C. Tumor, Node Involvement, Metastasis
- D. Therapy, Necrosis, Metastasis
Correct answer: B
Rationale: The TNM staging system is a classification system for determining the size and extent of cancerous tissue. The TNM system helps providers to identify the most accurate forms of treatment. The T stands for tumor, the N stands for node involvement, and the M stands for metastasis. Choice A, 'Tumor, Necrosis, Metastasis,' is incorrect because it does not include the node involvement component. Choice B, 'Tumor, Node Involvement, Mastectomy,' is incorrect as it erroneously includes the treatment approach 'Mastectomy' instead of 'Metastasis.' Choice D, 'Therapy, Necrosis, Metastasis,' is incorrect because it includes 'Therapy' instead of the correct component 'Node Involvement.'
2. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?
- A. Administer bicarbonate.
- B. Complete a head-to-toe assessment.
- C. Place the patient on high-flow oxygen.
- D. Obtain repeat arterial blood gases (ABGs).
Correct answer: C
Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.
3. Which individual is at greatest risk for developing hypertension?
- A. 45-year-old African-American attorney
- B. 60-year-old Asian-American shop owner
- C. 40-year-old Caucasian nurse
- D. 55-year-old Hispanic teacher
Correct answer: A
Rationale: African-Americans have a higher risk of developing hypertension compared to other ethnic groups. They tend to develop high blood pressure at younger ages and are more sensitive to salt, which increases their risk of hypertension. Additionally, studies have shown that African-Americans may respond differently to hypertensive drugs. Therefore, the 45-year-old African-American attorney is at the greatest risk for developing hypertension. The other choices do not specify factors that put them at a higher risk for hypertension compared to African-Americans.
4. A patient has been diagnosed with acute gastritis in a clinic. Which of the following medications would be contraindicated for this patient?
- A. Naproxen sodium (Naprosyn)
- B. Calcium carbonate
- C. Clarithromycin (Biaxin)
- D. Furosemide (Lasix)
Correct answer: A
Rationale: Naproxen sodium is a nonsteroidal anti-inflammatory drug that can cause inflammation of the upper GI tract. For this reason, it is contraindicated in a patient with gastritis. Gastritis involves inflammation of the stomach lining, and medications like Naproxen can exacerbate this condition. Calcium carbonate is an antacid that can help neutralize stomach acid and may actually provide relief for gastritis symptoms. Clarithromycin is an antibiotic used to treat H. pylori infection, a common cause of gastritis. Furosemide is a loop diuretic used to treat conditions like edema and hypertension, not directly contraindicated in gastritis.
5. The child with hemolytic-uremic syndrome is anuric and will undergo peritoneal dialysis. Which measure should the nurse implement?
- A. Restrict fluids as prescribed.
- B. Care for the arteriovenous fistula.
- C. Encourage foods high in potassium.
- D. Administer analgesics as prescribed.
Correct answer: A
Rationale: In hemolytic-uremic syndrome, often associated with bacterial toxins and viruses, acute kidney injury occurs in children, leading to symptoms like anemia, thrombocytopenia, renal injury, and CNS symptoms. For an anuric child with hemolytic-uremic syndrome undergoing peritoneal dialysis, fluid restriction is vital to prevent fluid overload. Pain management is not directly related to hemolytic-uremic syndrome. Foods high in potassium should be limited, not encouraged, due to impaired kidney function. Peritoneal dialysis does not involve an arteriovenous fistula, which is specific to hemodialysis.
