NCLEX RN Exam Review Answers
1. The healthcare provider is reviewing the lab results of a patient who has presented in the Emergency Room. The lab results show that the troponin T value is at 5.3 ng/mL. Which of these interventions, if not already completed, would take priority over the others?
- A. Place the patient in a 90-degree position
- B. Assess whether the patient is taking diuretics
- C. Obtain and attach defibrillator leads
- D. Assess the patient's last ejection fraction
Correct answer: C
Rationale: In this scenario, the elevated Troponin T level indicates cardiac damage, possibly due to a myocardial infarction. A Troponin T value of 5.3 ng/mL is significantly elevated (normal levels are below 0.2 ng/mL), suggesting acute cardiac injury. Given the setting of an Emergency Room and the critical nature of the situation, the priority intervention should be to obtain and attach defibrillator leads. Elevated Troponin T levels can indicate a higher risk of arrhythmias, including ventricular fibrillation, which can lead to sudden cardiac arrest. Defibrillator leads are essential for monitoring the patient's cardiac rhythm and readiness for immediate defibrillation if necessary. Placing the patient in a 90-degree position (Choice A) or assessing diuretic use (Choice B) are not immediate priorities in this critical situation. Additionally, assessing the patient's last ejection fraction (Choice D) is important but not as urgent as preparing for potential life-threatening arrhythmias requiring defibrillation.
2. When caring for a patient hospitalized with active tuberculosis (TB), the nurse observes a student nurse who is assigned to take care of the patient. Which action, if performed by the student nurse, would require an intervention by the nurse?
- A. The patient is offered a tissue from the box at the bedside.
- B. A surgical face mask is applied before visiting the patient.
- C. A snack is brought to the patient from the unit refrigerator.
- D. Hand washing is performed before entering the patient's room.
Correct answer: B
Rationale: When caring for a patient with active tuberculosis (TB), it is crucial to use a high-efficiency particulate-absorbing (HEPA) mask instead of a standard surgical mask when entering the patient's room, as a HEPA mask can filter out 100% of small airborne particles, reducing the risk of transmission. Therefore, if the student nurse applies only a surgical face mask before visiting the patient, this action would require intervention by the nurse to ensure the appropriate protective equipment is used. Hand washing before entering the patient's room is essential to prevent the spread of infection and is a correct action. Bringing a snack to the patient from the unit refrigerator is appropriate and helps address potential issues with anorexia and weight loss in patients with TB. While hand washing after handling a tissue used by the patient is necessary, no special precautions are required when offering the patient an unused tissue.
3. While planning care for a 2-year-old hospitalized child, which situation would the nurse expect to most likely affect the behavior?
- A. Strange bed and surroundings
- B. Separation from parents
- C. Presence of other toddlers
- D. Unfamiliar toys and games
Correct answer: B
Rationale: The correct answer is 'Separation from parents.' Separation anxiety is most evident from 6 months to 30 months of age and is the greatest stress imposed on a toddler by hospitalization. If separation is avoided, young children have a tremendous capacity to withstand other stress. The other choices, such as 'Strange bed and surroundings,' 'Presence of other toddlers,' and 'Unfamiliar toys and games,' may also have an impact on the child, but separation from parents is typically the most significant factor affecting behavior in a hospitalized 2-year-old.
4. A 53-year-old patient is being treated for bleeding esophageal varices with balloon tamponade. Which nursing action will be included in the plan of care?
- A. Instruct the patient to cough every hour
- B. Monitor the patient for shortness of breath
- C. Verify the position of the balloon every 4 hours
- D. Deflate the gastric balloon if the patient reports nausea
Correct answer: B
Rationale: The correct nursing action for a patient with balloon tamponade for bleeding esophageal varices is to monitor the patient for shortness of breath. The most common complication of balloon tamponade is aspiration pneumonia. Additionally, if the gastric balloon ruptures, the esophageal balloon may slip upward and occlude the airway. Instructing the patient to cough every hour is incorrect as coughing increases the pressure on the varices and raises the risk of bleeding. Verifying the position of the balloon every 4 hours is unnecessary as it is typically done after insertion. Deflating the gastric balloon if the patient reports nausea is incorrect because deflating it may cause the esophageal balloon to occlude the airway, leading to complications. Therefore, monitoring for signs of respiratory distress is crucial in this situation.
5. The nurse administers prescribed therapies for a patient with cor pulmonale and right-sided heart failure. Which assessment would best evaluate the effectiveness of the therapies?
- A. Observe for distended neck veins.
- B. Auscultate for crackles in the lungs.
- C. Palpate for heaves or thrills over the heart.
- D. Review hemoglobin and hematocrit values.
Correct answer: A
Rationale: To evaluate the effectiveness of therapies for cor pulmonale and right-sided heart failure, observing for distended neck veins would be the most appropriate assessment. Cor pulmonale is characterized by right ventricular failure due to pulmonary hypertension, leading to clinical manifestations such as peripheral edema, jugular venous distention, and right upper-quadrant abdominal tenderness. These signs indicate increased central venous pressure and right heart strain, which can be assessed by observing for distended neck veins. Auscultating for crackles in the lungs is more indicative of left-sided heart failure rather than right-sided heart failure. Heaves or thrills over the heart are not typically associated with cor pulmonale. Reviewing hemoglobin and hematocrit values may show elevations due to chronic hypoxemia and polycythemia in cor pulmonale, but these values alone do not directly evaluate the immediate effectiveness of the prescribed therapies on the patient's condition.
