1. What is the first step in preparing a blood transfusion?

A. Administer the blood via IV push
B. Verify the client's blood type before starting the transfusion
C. Warm the blood to body temperature before administration
D. Administer diuretics to prevent fluid overload

Correct answer: B

Rationale: The correct first step in preparing a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to ensure compatibility and prevent adverse reactions. Administering the blood via IV push (Choice A) is incorrect as it skips the essential step of verifying the blood type. Warming the blood to body temperature (Choice C) is important but comes after verifying the blood type. Administering diuretics (Choice D) is not part of the preparation process for a blood transfusion.

2. What are the key differences between systolic and diastolic heart failure?

A. Systolic: Reduced ejection fraction; Diastolic: Preserved ejection fraction
B. Systolic: Preserved ejection fraction; Diastolic: Reduced ejection fraction
C. Systolic: Right-sided heart failure; Diastolic: Left-sided heart failure
D. Systolic: Pulmonary congestion; Diastolic: Systemic congestion

Correct answer: A

Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.

3. How should a healthcare professional respond to a patient with diabetic ketoacidosis (DKA)?

A. Administer insulin
B. Administer IV fluids
C. Monitor blood glucose
D. All of the above

Correct answer: D

Rationale: When managing a patient with diabetic ketoacidosis (DKA), it is crucial to administer insulin to lower blood sugar levels, administer IV fluids to correct dehydration and electrolyte imbalances, and monitor blood glucose levels regularly to ensure they are within the target range. Therefore, all of the above options are essential components of the comprehensive treatment plan for DKA. Administering insulin alone may lower blood sugar levels but will not address the fluid and electrolyte imbalances seen in DKA. Similarly, administering IV fluids alone may help with dehydration but will not address the high blood sugar levels or the need for insulin. Monitoring blood glucose alone is not sufficient to treat DKA; it must be accompanied by appropriate interventions to address the underlying causes and complications of the condition.

4. A charge nurse is teaching new staff members about factors that increase a client's risk of becoming violent. Which of the following risk factors should the nurse include as the best predictor of future violence?

A. Experiencing delusions.
B. Male gender.
C. Previous violent behavior.
D. A history of being in prison.

Correct answer: C

Rationale: The correct answer is C: Previous violent behavior. This is considered the best predictor of future violent actions as individuals who have a history of violent behavior are more likely to engage in violent acts again. Option A, experiencing delusions, although it can impact behavior, is not as strong of a predictor as past violent behavior. Option B, male gender, is a demographic factor but not as specific or predictive as a history of violence. Option D, a history of being in prison, may indicate past behavior but is not directly linked to future violent actions as a known history of violence.

5. A client with a tracheostomy is exhibiting signs of respiratory distress. What should the nurse do first?

A. Notify the healthcare provider
B. Suction the tracheostomy
C. Administer a bronchodilator
D. Increase the oxygen flow rate

Correct answer: B

Rationale: When a client with a tracheostomy is experiencing respiratory distress, the priority action is to suction the tracheostomy to clear the airway and improve breathing. This helps remove secretions or blockages that may be causing the distress. Notifying the healthcare provider (Choice A) can be done after ensuring immediate airway clearance. Administering a bronchodilator (Choice C) would not address the primary issue of airway clearance in a tracheostomy patient. Increasing the oxygen flow rate (Choice D) may be necessary but should come after ensuring the airway is clear.
