NCLEX RN Exam Review Answers

1. A patient is suspected to have sustained a spinal cord injury. What best describes the overarching principles used to guide the care for this type of condition?

A. Immobilize the cervical area to prevent further injury
B. Monitor the patient's level of consciousness to prevent neurologic deterioration
C. Help the patient with activities of daily living and provide emotional and physical support to help them adjust to their injury
D. Facilitate tissue perfusion to the spinal cord while maintaining airway and breathing

Correct answer: D

Rationale: The correct answer is to facilitate tissue perfusion to the spinal cord while maintaining airway and breathing. In the acute phase of a spinal cord injury, ensuring proper tissue perfusion to the spinal cord is crucial to prevent further damage. Maintaining airway, breathing, and circulation is essential in guiding the overall care for a patient with a spinal cord injury. Choices A, B, and C, while important in certain aspects of care, are not the overarching principles that guide the immediate management of a suspected spinal cord injury.

2. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

A. 60 microdrops/minute
B. 20 microdrops/minute
C. 30 microdrops/minute
D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

3. 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.

4. Which topic is most important to include in patient teaching for a 41-year-old patient diagnosed with early alcoholic cirrhosis?

A. Maintaining good nutrition
B. Avoiding alcohol ingestion
C. Taking lactulose (Cephulac)
D. Using vitamin B supplements

Correct answer: B

Rationale: The most important topic to include in patient teaching for a 41-year-old patient diagnosed with early alcoholic cirrhosis is avoiding alcohol ingestion. Alcohol abstinence is crucial in stopping or reversing the progression of the disease. While maintaining good nutrition, taking lactulose (Cephulac), and using vitamin B supplements are important interventions in managing cirrhosis, abstaining from alcohol is the priority for this patient to prevent further damage to the liver and halt disease progression.

5. The clinic nurse reviews the record of an infant and notes that the primary healthcare provider has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek healthcare for the infant?

A. Diarrhea
B. Projectile vomiting
C. Regurgitation of feedings
D. Foul-smelling, ribbon-like stools

Correct answer: D

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is a congenital anomaly characterized by an absence of ganglion cells in the rectum and other areas of the affected intestine. A key clinical manifestation of Hirschsprung's disease is chronic constipation that starts in the first month of life, leading to pellet-like or ribbon-like stools that have a foul smell. Another sign is the delayed passage or absence of meconium stool in the neonatal period. In addition to foul-smelling, ribbon-like stools, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive are also common clinical manifestations of this disorder. Options A, B, and C are not typically associated with Hirschsprung's disease, making them incorrect choices in this scenario.
