NCLEX RN Exam Review Answers
1. A patient is found unconscious in their room with rhythmic jerking of all four extremities and heavy foaming at the mouth. The patient was on seizure precautions with bedrails up and padded. What is the priority action for the nurse to take?
- A. Administer Lorazepam (Ativan)
- B. Turn the patient to his/her side
- C. Call the physician
- D. Suction the patient
Correct answer: B
Rationale: The nurse's priority action should be to turn the patient to his/her side. This position helps maintain an open airway and prevents aspiration of secretions or vomitus. Administering Lorazepam (Ativan) without ensuring a clear airway could lead to further complications. Calling the physician is important, but immediate interventions to protect the airway take precedence. Suctioning the patient may be necessary but should not be the initial action; positioning for airway protection is the priority.
2. 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.
3. Renal failure is broadly divided into specific categories. Which type is the type II diabetic patient most likely to experience secondary to diabetes?
- A. Acute renal failure (ARF)
- B. Intermittent renal failure (IRF)
- C. Chronic renal failure (CRF)
- D. Reversible renal failure (RRF)
Correct answer: C
Rationale: Diabetic nephropathy is a common complication in type II diabetic patients, leading to chronic renal failure (CRF). Chronic renal failure (CRF) and acute renal failure (ARF) are the two main categories of renal failure. CRF can result from various conditions including diabetic nephropathy, chronic glomerulonephritis, chronic pyelonephritis, polycystic kidney disease, connective tissue disorders, and amyloidosis. Unlike acute renal failure, chronic renal failure is irreversible. Timely treatment of ARF can often lead to reversibility, but CRF may require renal replacement therapy (RRT) or kidney transplant. Therefore, the correct answer is chronic renal failure (CRF). Intermittent renal failure (IRF) and reversible renal failure (RRF) are not recognized medical terms for distinct types of renal failure, making choices B and D incorrect.
4. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?
- A. The medication will reduce the risk of aspiration.
- B. The medication will inhibit the development of gastric ulcers.
- C. The medication will prevent irritation of the enlarged veins.
- D. The medication will decrease nausea and improve appetite.
Correct answer: C
Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.
5. 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.
