NCLEX RN Exam Review Answers
1. What is a priority problem for a child with severe edema caused by nephrotic syndrome?
- A. Risk for constipation
- B. Risk for skin breakdown
- C. Inability to regulate body temperature
- D. Consuming more calories or nutrients than the body requires
Correct answer: B
Rationale: In nephrotic syndrome, characterized by massive proteinuria, hypoalbuminemia, and edema, a child with severe edema is at high risk for skin breakdown. The priority concern is to prevent skin breakdown by cleaning skin surfaces and ensuring adequate separation with clothing to avoid irritation. The child with nephrotic syndrome is typically anorexic, making consuming more calories or nutrients than necessary not a concern. Risk for constipation and inability to regulate body temperature are not primary issues associated with edema caused by nephrotic syndrome.
2. The clinic nurse is obtaining data about a child with a diagnosis of lactose intolerance. Which data should the nurse expect to obtain on assessment?
- A. Reports of frothy stools and diarrhea
- B. Reports of foul-smelling ribbon stools
- C. Reports of profuse, watery diarrhea and vomiting
- D. Reports of diffuse abdominal pain unrelated to meals or activity
Correct answer: A
Rationale: Lactose intolerance commonly presents with frothy stools and diarrhea due to the inability to digest lactose. Other symptoms include abdominal distension, crampy abdominal pain, and excessive flatus. Foul-smelling ribbon stools are indicative of Hirschsprung's disease, not lactose intolerance. Profuse, watery diarrhea and vomiting are more characteristic of celiac disease. Diffuse abdominal pain unrelated to meals or activity is a typical symptom of irritable bowel syndrome, not lactose intolerance.
3. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?
- A. The bicarbonate level (HCO3) is 31 mEq/L
- B. The arterial oxygen saturation (SaO2) is 92%
- C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
- D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg
Correct answer: D
Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.
4. 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.
5. A 49-year-old female patient with cirrhosis and esophageal varices has a new prescription for propranolol (Inderal). Which finding is the best indicator that the medication has been effective?
- A. The patient reports no chest pain.
- B. Blood pressure is 140/90 mm Hg
- C. Stools test negative for occult blood.
- D. The apical pulse rate is 68 beats/minute.
Correct answer: C
Rationale: The best indicator that propranolol has been effective in a patient with cirrhosis and esophageal varices is when the stools test negative for occult blood. Propranolol is prescribed to decrease the risk of bleeding from esophageal varices. This medication's effectiveness is primarily assessed by the absence of blood in the stools, indicating a reduction in the risk of bleeding from the varices. Monitoring for chest pain, blood pressure control, and a decrease in heart rate are important parameters in other conditions treated with propranolol, such as hypertension, angina, and tachycardia, but in this particular case, the absence of occult blood in the stools is the most relevant indicator of treatment success.
