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. To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:
- A. Assist the client in using the bedside commode
- B. Administer stool softeners daily as prescribed
- C. Administer antidysrhythmics PRN as prescribed
- D. Maintain the client on strict bed rest
Correct answer: B
Rationale: Administering stool softeners daily as prescribed is essential to prevent straining during defecation, which can lead to a Valsalva maneuver. Straining can increase intra-abdominal pressure, hinder venous return, and elevate blood pressure, risking cardiac complications in a client recovering from a heart attack. Using a bedside commode might be useful to minimize exertion during toileting but does not directly address the risk of a Valsalva maneuver. Administering antidysrhythmics PRN is not the primary intervention for preventing a Valsalva maneuver; these medications are used to manage dysrhythmias if they occur. Keeping the client on strict bed rest is not the best option as early mobilization is encouraged in post-myocardial infarction recovery to prevent complications such as deep vein thrombosis and muscle weakness.
3. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?
- A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
- B. The ventilator coordinates delivered breaths with the client's respiratory efforts
- C. The ventilator provides a supplemental breath for every third breath of the client
- D. The ventilator provides breaths during the expiratory phase of the client's respirations
Correct answer: B
Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.
4. 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.
5. A client is brought into the emergency room where the physician suspects that he has cardiac tamponade. Based on this diagnosis, the nurse would expect to see which of the following signs or symptoms in this client?
- A. Fever, fatigue, malaise
- B. Hypotension and distended neck veins
- C. Cough and hemoptysis
- D. Numbness and tingling in the extremities
Correct answer: B
Rationale: Cardiac tamponade occurs when fluid or blood accumulates in the pericardium, preventing the heart from contracting properly. This leads to decreased cardiac output and is considered a medical emergency. Classic signs of cardiac tamponade include hypotension (low blood pressure) and distended neck veins due to the increased pressure around the heart. These signs result from the compromised ability of the heart to pump effectively. Choices A, C, and D are not typically associated with cardiac tamponade. Fever, fatigue, and malaise are non-specific symptoms that can be seen in various conditions. Cough and hemoptysis are more commonly associated with respiratory conditions, while numbness and tingling in the extremities are neurological symptoms not typically seen in cardiac tamponade.
