1. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. A nurse is collecting data from a newly-admitted infant who is 3 months old and has diarrhea. Which of the following findings should the nurse report to the provider?

• A. Weight gain
• B. Poor appetite
• C. Irritability
• D. Decreased urination

Correct answer: C

Rationale: Irritability in infants can indicate worsening dehydration, which needs to be reported. Weight gain (Choice A) would be a positive finding, indicating adequate fluid intake. Poor appetite (Choice B) is common with diarrhea but not as concerning as irritability. Decreased urination (Choice D) can also be a sign of dehydration, but irritability is more specific to worsening dehydration in this case.

3. What are the signs of an acute myocardial infarction?

• A. Chest pain radiating to the arm and shortness of breath
• B. Nausea, vomiting, and high fever
• C. Headache, confusion, and low blood pressure
• D. Increased heart rate and bradycardia

Correct answer: A

Rationale: The correct answer is A: Chest pain radiating to the arm and shortness of breath. These are classic signs of an acute myocardial infarction. Choice B is incorrect because nausea, vomiting, and high fever are not typical signs of a heart attack. Choice C is incorrect as headache, confusion, and low blood pressure are not specific to myocardial infarction. Choice D is incorrect because an acute myocardial infarction typically presents with an increased heart rate, not bradycardia.

4. A client with an acute myocardial infarction is concerned about extreme fatigue. What is the best strategy to promote independence in self-care?

• A. Instruct the client to limit all activity until fully rested
• B. Encourage the client to gradually resume self-care tasks with rest periods
• C. Assign assistive personnel to complete self-care tasks
• D. Ask the client's family to assist with self-care

Correct answer: B

Rationale: Encouraging the client to gradually resume self-care tasks with rest periods is the best strategy to promote independence in self-care for a client with acute myocardial infarction. This approach allows the client to regain independence while considering the need for rest to prevent overexertion. Instructing the client to limit all activity until fully rested (Choice A) may hinder independence by promoting inactivity. Assigning assistive personnel to complete self-care tasks (Choice C) does not promote the client's independence. Asking the client's family to assist with self-care (Choice D) may not foster the client's self-reliance and may not always be feasible.

5. Which of the following is an early indication that a tracheostomy client requires suctioning?

• A. Bradycardia
• B. Irritability
• C. Hypotension
• D. Decreased respiratory rate

Correct answer: B

Rationale: Irritability is indeed an early sign that a tracheostomy client may require suctioning. When a tracheostomy client becomes irritable, it can indicate that there is a need for suctioning to clear the airway. Bradycardia (choice A) refers to a slow heart rate and is not typically a direct indication for suctioning. Hypotension (choice C) indicates low blood pressure and is not specifically related to the need for suctioning. Decreased respiratory rate (choice D) can be a sign of respiratory distress, but irritability is a more direct and early indication of the need for suctioning in a tracheostomy client.
