NCLEX RN Exam Questions
1. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?
- A. Hemoglobin of 11 g/dl
- B. Platelet count of 150,000
- C. INR of 2.5
- D. Potassium of 2.7 mEq/L
Correct answer: D
Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.
2. Based on Mr. C's assessment, which of the following nursing interventions is most appropriate?
- A. Elevate the lower extremities to 45 degrees to promote venous return
- B. Place Mr. C in the Trendelenburg position
- C. Administer total parenteral nutrition
- D. Monitor urine output
Correct answer: D
Rationale: In the context of Mr. C's assessment, the most appropriate nursing intervention is to monitor urine output. A client in hypovolemic shock may experience decreased urine output due to poor kidney perfusion. By monitoring urine output, the nurse can assess renal function and fluid status. Administering total parenteral nutrition (Choice C) is not indicated based on the information provided, as the priority is to stabilize the client's condition. Elevating the lower extremities (Choice A) may be helpful in some cases but is not the priority in this situation. Placing Mr. C in the Trendelenburg position (Choice B) is contraindicated in hypovolemic shock as it can worsen venous return and compromise cardiac output.
3. A child presents to the emergency department with colicky abdominal pain in the lower right quadrant. What disorder is suspected based on these symptoms?
- A. Peritonitis
- B. Appendicitis
- C. Intussusception
- D. Hirschsprung's disease
Correct answer: B
Rationale: The child's presentation of colicky abdominal pain in the lower right quadrant is classic for appendicitis. Appendicitis typically presents with localized pain that starts near the umbilicus and then shifts to the right lower quadrant. Peritonitis, on the other hand, is characterized by diffuse abdominal pain, tenderness, and guarding, usually resulting from organ perforation or intestinal obstruction. Intussusception is associated with acute, severe abdominal pain and currant jelly-like stools due to intestinal telescoping. Hirschsprung's disease, which lacks ganglion cells in the colon, manifests with symptoms like constipation, abdominal distension, and foul-smelling, ribbon-like stools.
4. Mr. B is recovering from a surgical procedure that was performed four days ago. The nurse's assessment finds this client coughing up rust-colored sputum; his respiratory rate is 28/minute with expiratory grunting, and his lung sounds have coarse crackles on auscultation. Which of the following conditions is the most likely cause of these symptoms?
- A. Tuberculosis
- B. Pulmonary edema
- C. Pneumonia
- D. Histoplasmosis
Correct answer: C
Rationale: In this scenario, the client's presentation of coughing up rust-colored sputum, increased respiratory rate, expiratory grunting, and coarse crackles on lung auscultation suggests the development of pneumonia. Pneumonia is characterized by lung tissue inflammation or infection, often caused by various organisms. Symptoms may include productive cough, dyspnea, and abnormal breath sounds. Tuberculosis (Choice A) typically presents with a chronic cough, weight loss, and night sweats and is less likely in this acute post-operative setting. Pulmonary edema (Choice B) is characterized by pink, frothy sputum, crackles throughout the lungs, and typically occurs in the context of heart failure. Histoplasmosis (Choice D) is a fungal infection that usually presents with flu-like symptoms and is less likely to manifest with the specific respiratory findings described in this case.
5. The nurse reviews the record of a newborn infant and notes that a diagnosis of esophageal atresia with tracheoesophageal fistula is suspected. The nurse expects to note which most likely sign of this condition documented in the record?
- A. Incessant crying
- B. Coughing at nighttime
- C. Choking with feedings
- D. Severe projectile vomiting
Correct answer: C
Rationale: In esophageal atresia and tracheoesophageal fistula, the esophagus ends before it reaches the stomach, forming a blind pouch, and there is an abnormal connection (fistula) with the trachea. Any child who exhibits the '3 Cs'"?coughing and choking with feedings and unexplained cyanosis"?should be suspected to have tracheoesophageal fistula. Option A, 'Incessant crying,' is not a typical sign of esophageal atresia with tracheoesophageal fistula. Option B, 'Coughing at nighttime,' is not a specific sign associated with this condition. Option D, 'Severe projectile vomiting,' is not a common sign of esophageal atresia with tracheoesophageal fistula.
