NCLEX RN Exam Review Answers
1. During an assessment of a child admitted to the hospital with a probable diagnosis of nephrotic syndrome, what assessment findings should the nurse expect to observe? Select one that applies.
- A. Proteinuria
- B. Weight gain
- C. Decreased serum lipids
- D. Hematuria
Correct answer: A
Rationale: In nephrotic syndrome, the hallmark finding is massive proteinuria due to increased glomerular permeability. This leads to hypoalbuminemia, resulting in generalized edema. Weight gain, not weight loss, is typically seen due to fluid retention. Serum lipids are elevated, not decreased, in nephrotic syndrome. Hematuria, the presence of blood in the urine, is not a typical finding in nephrotic syndrome.
2. Which of the following clients is most appropriate for receiving telemetry?
- A. A client with syncope potentially related to cardiac dysrhythmia
- B. A client with unstable angina
- C. A client with sinus rhythm and PVCs
- D. A client who had a myocardial infarction 6 hours ago
Correct answer: A
Rationale: Telemetry is used to monitor the cardiac rhythms of clients with potentially unstable conditions or those rhythms that affect activities. Clients with syncope potentially related to cardiac dysrhythmia require continuous monitoring to detect any potential life-threatening dysrhythmias. Unstable angina can be monitored in a telemetry unit, but syncope with potential cardiac causes takes precedence. Clients with sinus rhythm and PVCs may not necessitate telemetry unless there are further indications of instability. A client who had a myocardial infarction 6 hours ago is typically monitored in an intensive care unit rather than a telemetry unit.
3. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:
- A. Urinary output of 30 ml per hour
- B. No complaints of thirst
- C. Increased hematocrit
- D. Good skin turgor around burn
Correct answer: A
Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.
4. What drives respiration in a patient with advanced chronic respiratory failure?
- A. Hypoxemia
- B. Hypocapnia
- C. Hypercapnia
- D. None of the above
Correct answer: A
Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
5. A client is found unresponsive in his room by a nurse. The client is not breathing and does not have a pulse. After calling for help, what is the next action the nurse should take?
- A. Administer 2 ventilations
- B. Perform a head-tilt, chin lift to open the airway
- C. Begin chest compressions
- D. Perform a jaw thrust to open the airway
Correct answer: C
Rationale: After finding an unresponsive client who is not breathing and has no pulse, the nurse's immediate action should be to call for help and start chest compressions. Chest compressions should be initiated at a rate of at least 100 per minute and a depth of at least 2 inches. Choice A, administering ventilations, is not the initial step as compressions take priority. Choice B, performing a head-tilt, chin lift, is also not the first step; chest compressions are crucial before airway management. Choice D, performing a jaw thrust, is typically used in cases of suspected cervical spine injury and is not the immediate action in this scenario.
