Nursing Elites

1. What is a causative factor of Hirschsprung disease?

• A. Frequent evacuation of solids, liquid, and gases
• B. Excessive peristaltic movement
• C. The absence of parasympathetic ganglion cells in a portion of the colon
• D. One portion of the bowel telescoping into another

Correct answer: C

Rationale: The correct answer is C: The absence of parasympathetic ganglion cells in a portion of the colon is a causative factor of Hirschsprung disease. This absence leads to the inability of the affected segment of the colon to relax, causing a functional obstruction. Choices A, B, and D are incorrect. Frequent evacuation of solids, liquid, and gases, excessive peristaltic movement, and one portion of the bowel telescoping into another are not causative factors of Hirschsprung disease.

2. A client admitted with left-sided heart failure has a heart rate of 110 beats per minute and is becoming increasingly dyspneic. Which additional assessment finding by the nurse supports the client’s admitting diagnosis?

• A. Jugular vein distention.
• B. Crackles in the lung bases.
• C. Peripheral edema.
• D. Bounding peripheral pulses.

Correct answer: B

Rationale: The correct answer is B: Crackles in the lung bases. Crackles in the lung bases are indicative of pulmonary congestion, which is a classic sign of left-sided heart failure. Left-sided heart failure leads to a backup of blood into the lungs, causing fluid leakage into the alveoli and resulting in crackles upon auscultation. Choices A, C, and D are less specific to left-sided heart failure. Jugular vein distention can be seen in right-sided heart failure, peripheral edema can be seen in both right and left-sided heart failure, and bounding peripheral pulses are more indicative of conditions like hyperthyroidism or anemia rather than specifically supporting left-sided heart failure.

3. A client with a history of hypertension is admitted with a blood pressure of 220/120 mm Hg. What is the priority nursing action?

• A. Administer antihypertensive medication as prescribed.
• B. Place the client in a supine position.
• C. Obtain a detailed health history.
• D. Monitor urine output.

Correct answer: A

Rationale: Administering antihypertensive medication is the priority nursing action in this situation. The extremely high blood pressure of 220/120 mm Hg puts the client at risk of severe complications such as stroke, heart attack, or kidney damage. Lowering the blood pressure promptly is crucial to prevent these complications. Placing the client in a supine position or obtaining a detailed health history are not immediate actions needed to address the hypertensive crisis. Monitoring urine output, although important, is not the priority when the client's blood pressure is critically high.

4. The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?

• A. Bilateral crackles in the lung bases.
• B. Low-pressure indicator alarm.
• C. Oxygen saturation of 91%.
• D. Respiratory rate of 18 breaths/minute.

Correct answer: B

Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.

5. The healthcare provider is assessing a client with a chest tube. Which finding indicates that the chest tube is functioning properly?

• A. Continuous bubbling in the water seal chamber
• B. Tidaling in the water seal chamber
• C. Absence of drainage in the collection chamber
• D. Fluid level in the suction control chamber is below the prescribed level

Correct answer: B

Rationale: Tidaling in the water seal chamber indicates proper chest tube function. Tidaling refers to the rise and fall of fluid in the water seal with inhalation and exhalation, demonstrating the patency of the system. Continuous bubbling (Choice A) in the water seal chamber indicates an air leak. Absence of drainage in the collection chamber (Choice C) is not a desired finding as it suggests no drainage is occurring. A fluid level below the prescribed level in the suction control chamber (Choice D) may indicate inadequate suction.
