Nursing Elites

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. 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.

3. A client who is postoperative following a cholecystectomy has a urine output of 25 mL/hr. Which of the following findings should the nurse report to the provider?

• A. Abdominal pain radiating to the right shoulder.
• B. Absent bowel sounds.
• C. Brown drainage on the surgical dressing.
• D. Urine output of 25 mL/hr.

Correct answer: D

Rationale: A urine output below 30 mL/hr indicates a potential complication, such as hypovolemia or renal impairment, and should be reported. Abdominal pain radiating to the right shoulder can be common after a cholecystectomy due to referred pain from the diaphragm, whereas absent bowel sounds may be expected temporarily postoperatively. Brown drainage on the surgical dressing is typical in the early postoperative period and may represent old blood or other normal discharge.

4. A nurse is planning care for a client who is at 28 weeks of gestation and has preeclampsia. Which of the following interventions should the nurse include in the plan?

• A. Restrict the client's fluid intake.
• B. Monitor the client's deep-tendon reflexes.
• C. Place the client in the lithotomy position.
• D. Encourage the client to ambulate frequently.

Correct answer: B

Rationale: The correct answer is to monitor the client's deep-tendon reflexes. Monitoring deep-tendon reflexes is crucial in clients with preeclampsia as hyperreflexia can indicate severe complications. Restricting the client's fluid intake is not recommended as hydration is essential. Placing the client in the lithotomy position can worsen preeclampsia by reducing blood flow to the heart, so it should be avoided. Encouraging the client to ambulate frequently may not be suitable for a client with preeclampsia due to the risk of falls and increased stress on the body.

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.
