NCLEX RN Exam Review Answers

1. Which of the following patients is at the greatest risk for a stroke?

A. A 60-year-old male who weighs 270 pounds, has atrial fibrillation, and has had a TIA in the past
B. A 75-year-old male who has frequent migraines, drinks a glass of wine every day, and is Hispanic
C. A 40-year-old female who has high cholesterol and uses oral contraceptives
D. A 65-year-old female who is African American, has sickle cell disease, and smokes cigarettes

Correct answer: A

Rationale: The correct answer is the 60-year-old male who has a combination of significant risk factors for stroke, including atrial fibrillation, a history of a transient ischemic attack (TIA), and obesity. These factors greatly increase his risk of stroke. While other choices may have some individual risk factors, they do not collectively pose as high a risk as the patient described in option A. Option B includes migraines and alcohol consumption but lacks other major risk factors seen in option A. Option C mentions high cholesterol and oral contraceptives, which are risk factors but not as significant as atrial fibrillation and a prior TIA. Option D includes smoking and sickle cell disease but lacks the crucial risk factors present in option A.

2. The nurse is caring for a patient in the ICU who has had a spinal cord injury. She observes that his last blood pressure was 100/55, and his pulse is 48. These have both trended downwards from the baseline. What should the nurse expect to be the next course of action ordered by the physician?

A. Assess the patient for decreased level of consciousness
B. Administer Normal Saline
C. Insert an NG Tube
D. Connect and read an EKG

Correct answer: B

Rationale: The patient is entering neurogenic shock due to the spinal cord injury, leading to hypotension and bradycardia. Administering Normal Saline is essential to replace fluid volume, which can help in treating the hypotension and bradycardia symptomatically. This intervention aims to stabilize the patient's cardiovascular status. Assessing for decreased level of consciousness (Choice A) may be important but addressing the hemodynamic instability takes precedence. Inserting an NG Tube (Choice C) and connecting and reading an EKG (Choice D) are not the immediate actions required for the presenting symptoms of hypotension and bradycardia.

3. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

A. Diarrhea and Vomiting
B. Dizziness and Drowsiness
C. Metallic taste
D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.

4. A 4-year-old hospitalized child begins to have a seizure while playing with hard plastic toys in the hallway. Of the following nursing actions, which one should the nurse do first?

A. Place the child in the nearest bed
B. Administer IV medication to slow down the seizure
C. Place a padded tongue blade in the child's mouth
D. Remove the child's toys from the immediate area

Correct answer: D

Rationale: During a seizure, the priority nursing actions are to ensure the safety of the child and maintain airway patency. Placing objects in the child's mouth, like a padded tongue blade, is not recommended as it can lead to injury or obstruction of the airway. Moving the child to a bed is also not the immediate priority during a seizure. Administering IV medication to slow down the seizure is not typically done as the initial action. Therefore, the correct first nursing action is to remove any potential hazards, such as the hard plastic toys, from the immediate area to prevent injury during the seizure.

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.
