PN Exit Exam 2023 Quizlet
1. After a hip replacement surgery, a client is instructed to use an abduction pillow while in bed. What is the primary purpose of this device?
- A. To reduce the risk of blood clots.
- B. To prevent hip dislocation.
- C. To improve circulation in the legs.
- D. To alleviate pain and discomfort.
Correct answer: B
Rationale: The primary purpose of using an abduction pillow after hip replacement surgery is to prevent hip dislocation. The abduction pillow keeps the legs separated, which reduces the risk of hip dislocation by preventing excessive internal rotation and adduction of the hip joint. Choices A, C, and D are incorrect as the main goal of using the abduction pillow is to maintain proper positioning and stability of the hip joint to prevent dislocation, rather than addressing blood clots, circulation, or pain relief.
2. Which laboratory value is most important to monitor for a patient receiving heparin therapy?
- A. Platelet count
- B. Prothrombin time (PT)
- C. Partial thromboplastin time (PTT)
- D. International normalized ratio (INR)
Correct answer: C
Rationale: The correct answer is C, Partial thromboplastin time (PTT). PTT is monitored to assess the therapeutic effect of heparin therapy. It helps ensure that the heparin levels are within the desired range to prevent either clotting or excessive bleeding. Platelet count (A) is important but does not directly assess heparin's therapeutic effect. Prothrombin time (PT) (B) and International normalized ratio (INR) (D) are used to monitor patients on warfarin, not heparin therapy.
3. While turning and positioning a bedfast client, the PN observes that the client is dyspneic. Which action should the PN take first?
- A. Apply a pulse oximeter
- B. Measure blood pressure
- C. Notify the charge nurse
- D. Observe pressure areas
Correct answer: C
Rationale: Notifying the charge nurse promptly is the priority when a bedfast client is dyspneic. Dyspnea can indicate a serious problem that requires immediate assessment and intervention. Contacting the charge nurse ensures timely assistance and appropriate actions to address the client's condition. Applying a pulse oximeter or measuring blood pressure may provide valuable data, but the priority is prompt communication with the charge nurse to ensure quick intervention. Observing pressure areas, while important for overall client care, is not the most immediate action needed when a client is experiencing dyspnea.
4. The PN is caring for a laboring client whose last sterile vaginal examination revealed the cervix was 3 cm dilated, 50% effaced, and the presenting part was at 0 station. An hour later, the client tells the PN that she wants to go to the bathroom. Which action is most important for the PN to implement?
- A. Review the fetal heart rate and contraction pattern
- B. Check the perineum for an increase in bloody show
- C. Request a nurse to check the client's cervical dilation
- D. Palpate the client's bladder for distention
Correct answer: C
Rationale: The sudden urge to use the bathroom may indicate that labor is progressing quickly. Checking the cervical dilation will help determine if the client is in the transition phase of labor and if it is appropriate to allow her to get up. Reviewing the fetal heart rate and contraction pattern (Choice A) is important but not the most immediate action in this scenario. Checking the perineum for an increase in bloody show (Choice B) is relevant but not as crucial as assessing cervical dilation. Palpating the client's bladder for distention (Choice D) is not the priority when the client wants to go to the bathroom during labor.
5. What is the primary function of hemoglobin in red blood cells?
- A. Oxygen transport
- B. Immunity
- C. Blood clotting
- D. Carbon dioxide transport
Correct answer: A
Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.
