NCLEX RN Practice Questions Quizlet

1. 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.

2. The healthcare provider is managing a 20 lbs (9 kg) 6-month-old with a 3-day history of diarrhea, occasional vomiting, and fever. Peripheral intravenous therapy has been initiated, with 5% dextrose in 0.33% normal saline with 20 mEq of potassium per liter infusing at 35 ml/hr. Which finding should be immediately reported to the healthcare provider?

A. 3 episodes of vomiting in 1 hour.
B. Periodic crying and irritability.
C. Vigorous sucking on a pacifier.
D. No measurable voiding in 4 hours.

Correct answer: D

Rationale: The critical finding that should be reported immediately to the healthcare provider is 'No measurable voiding in 4 hours.' This finding raises concerns about possible hyperkalemia, which can result from continued potassium administration and a decrease in urinary output. Hyperkalemia can lead to serious complications, including cardiac arrhythmias. The management of acute hyperkalemia involves interventions such as administering calcium to protect the heart, shifting potassium into cells, and enhancing potassium elimination from the body. The other choices do not indicate an urgent issue that requires immediate attention. Three episodes of vomiting in 1 hour can be concerning but may not be as immediately critical as the risk of hyperkalemia. Periodic crying and irritability are common in infants and may not indicate a severe complication. Vigorous sucking on a pacifier is a normal behavior in infants and does not signal a medical emergency.

3. How does shock typically progress?

A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours

Correct answer: A

Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

4. Which patient is at risk for developing oral candidiasis, a type of stomatitis?

A. A 77-year-old woman in a long-term care facility taking an antibiotic
B. A 35-year-old man who has had HIV for 6 years
C. A 40-year-old man who is undergoing chemotherapy
D. An 80-year-old woman with dentures

Correct answer: A

Rationale: The correct answer is a 77-year-old woman in a long-term care facility taking an antibiotic. This patient has multiple risk factors for developing oral candidiasis, including older age, being in a long-term care facility, and taking antibiotics. Candidiasis can be caused by long-term antibiotic therapy, immunosuppressive therapy (such as chemotherapy), older age, living in a long-term care facility, diabetes, having dentures, and poor oral hygiene. Choices B, C, and D are less likely to be at high risk for oral candidiasis compared to the correct answer.

5. A client has no pulse or respirations. After calling for help, what should the nurse's first action be?

A. Start a peripheral IV
B. Initiate high-quality chest compressions
C. Establish an airway
D. Obtain the crash cart

Correct answer: B

Rationale: In a situation where a client has no pulse or respirations, the initial action recommended by the American Heart Association is to start high-quality chest compressions. This action helps maintain blood flow to vital organs such as the brain until normal heart rhythm is restored. Starting CPR with chest compressions before checking the airway and providing rescue breaths is crucial to improve outcomes. While establishing an airway and obtaining a crash cart are important steps in resuscitation, initiating chest compressions takes precedence to ensure oxygenated blood circulation. Starting with chest compressions applies to adults, children, and infants but not newborns.
