Nursing Elites

1. A client with a history of myocardial infarction is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. This test provides immediate information about the heart's electrical activity. Choice B, Chest X-ray, is used to visualize the structures of the chest, including the heart and lungs, but it does not directly assess for cardiac ischemia. Choice C, Arterial blood gases (ABGs), measures the oxygen and carbon dioxide levels in the blood and assesses acid-base balance, which is not the primary concern in this scenario. Choice D, Echocardiogram, is an ultrasound of the heart that provides information about the heart's structure and function, but it is not the initial diagnostic test for assessing cardiac ischemia in this situation.

2. A client with cirrhosis is admitted with jaundice and ascites. Which intervention should the nurse implement first?

• A. Administer a diuretic as prescribed.
• B. Administer lactulose as prescribed.
• C. Monitor the client's weight daily.
• D. Assess the client's neurological status.

Correct answer: B

Rationale: Administering lactulose is the first priority in managing a client with cirrhosis to reduce ammonia levels and prevent worsening hepatic encephalopathy. Lactulose helps in decreasing the absorption of ammonia in the intestines and promotes its excretion through the stool. This intervention is crucial in preventing the development or progression of hepatic encephalopathy. Administering a diuretic (Choice A) may be necessary to manage ascites, but it is not the priority over lactulose in this scenario. Monitoring the client's weight (Choice C) is important to assess fluid retention but is not the first intervention required. Assessing the client's neurological status (Choice D) is essential in cirrhosis, but administering lactulose takes precedence to prevent hepatic encephalopathy.

3. The nurse is assessing a client with left-sided heart failure. Which assessment finding requires immediate intervention?

• A. Jugular venous distention
• B. Shortness of breath
• C. Crackles in the lungs
• D. Peripheral edema

Correct answer: C

Rationale: In a client with left-sided heart failure, crackles in the lungs are a critical assessment finding that necessitates immediate intervention. Crackles indicate pulmonary congestion, a sign of worsening heart failure that requires prompt attention to prevent respiratory distress. Jugular venous distention, shortness of breath, and peripheral edema are also common in heart failure, but crackles specifically point to pulmonary involvement and the urgent need for intervention.

4. While auscultating a client's heart sounds, which description should the nurse use to document a swishing sound related to blood turbulence or valvular defect?

• A. S1 S2
• B. S1 S2 S3
• C. Murmur
• D. Pericardial friction rub

Correct answer: C

Rationale: The correct answer is 'C: Murmur.' A murmur is auscultated as a swishing sound associated with blood turbulence caused by the heart or a valvular defect. Choices 'A: S1 S2' and 'B: S1 S2 S3' refer to normal heart sounds, specifically the closure of heart valves. 'D: Pericardial friction rub' is a dry, rubbing or grating sound caused by inflammation of the pericardial sac and is not associated with blood flow or valvular issues.

5. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.
