Nursing Elites

1. What is the main symptom of left-sided heart failure?

• A. Shortness of breath
• B. Edema
• C. Increased heart rate
• D. Decreased urine output

Correct answer: A

Rationale: Shortness of breath is the main symptom of left-sided heart failure because it results from pulmonary congestion due to fluid buildup in the lungs. Edema, increased heart rate, and decreased urine output are associated with right-sided heart failure rather than left-sided heart failure.

2. A nurse is caring for a client who is experiencing post-traumatic stress disorder (PTSD). Which of the following manifestations should the nurse expect?

• A. Hyperactivity
• B. Hypervigilance
• C. Restlessness
• D. Avoidance of social situations

Correct answer: B

Rationale: The correct answer is B: Hypervigilance. Individuals with PTSD often experience hypervigilance, which involves being overly alert, easily startled, and constantly scanning their environment for potential threats. This heightened state of awareness is a common response to the trauma experienced. Choices A, C, and D are incorrect. Hyperactivity is not typically a primary manifestation of PTSD; restlessness may occur but is not as characteristic as hypervigilance, and although avoidance of social situations can be a symptom of PTSD, hypervigilance is more directly associated with the disorder.

3. How should a healthcare provider manage a patient with hyperkalemia?

• A. Administer insulin and glucose
• B. Restrict potassium intake
• C. Monitor ECG
• D. All of the above

Correct answer: D

Rationale: In managing hyperkalemia, it is essential to administer insulin and glucose to shift potassium into the cells, restrict potassium intake to prevent further elevation of serum levels, and monitor the ECG for signs of potassium-induced cardiac effects. Therefore, the correct answer is D, as all of the provided actions are important in the management of hyperkalemia. Choice A alone is not sufficient as it only addresses shifting potassium intracellularly without preventing further elevation. Choice B alone is not enough as it does not address the immediate need to lower serum potassium levels. Choice C alone is insufficient as it only monitors for cardiac effects without addressing potassium levels or shifting mechanisms.

4. What is the proper technique for measuring blood pressure manually?

• A. Use a stethoscope to listen for the Korotkoff sounds
• B. Ensure the patient is seated with the arm supported
• C. Use a manual sphygmomanometer
• D. Deflate the cuff slowly while listening to the heartbeat

Correct answer: A

Rationale: The correct technique for measuring blood pressure manually involves using a stethoscope to listen for the Korotkoff sounds. Choice B, ensuring the patient is seated with the arm supported, is important but not the specific technique for measuring blood pressure. Choice C, using a manual sphygmomanometer, is a necessary tool but not the technique itself. Choice D, deflating the cuff slowly while listening to the heartbeat, is not the correct technique as the deflation should be done while listening for the Korotkoff sounds to determine the systolic and diastolic blood pressure readings.

5. What is an early sign that suctioning is needed for a client with a tracheostomy?

• A. Bradycardia
• B. Irritability
• C. Hypotension
• D. Decreased oxygen saturation

Correct answer: B

Rationale: Irritability is an early sign that suctioning is needed for a client with a tracheostomy. When secretions accumulate in the airway, it can lead to discomfort and irritability in the client. Bradycardia, hypotension, and decreased oxygen saturation are usually later signs of inadequate airway clearance and oxygenation. Bradycardia may indicate severe hypoxia, while hypotension and decreased oxygen saturation are consequences of prolonged airway obstruction.
