1. When collecting data from a client with posttraumatic stress disorder (PTSD), which of the following manifestations should the nurse expect?
- A. Amnesia
- B. Hypervigilance
- C. Hallucinations
- D. Severe agitation
Correct answer: B
Rationale: The correct manifestation to expect when collecting data from a client with PTSD is hypervigilance. Hypervigilance refers to increased alertness, which is a common symptom of PTSD. This heightened state of awareness is characterized by an exaggerated startle response, being easily startled, and constantly scanning the environment for potential threats. Amnesia (choice A) is not typically a primary manifestation of PTSD; it is more commonly associated with dissociative disorders. Hallucinations (choice C) involve perceiving things that are not present and are not typically a hallmark symptom of PTSD. Severe agitation (choice D) may occur in individuals with PTSD, but hypervigilance is a more specific and common manifestation associated with this disorder.
2. What is the most appropriate next step when a client with an NG tube attached to low suctioning becomes nauseated, and the nurse observes a decrease in the flow of gastric secretions?
- A. Increase the suction pressure
- B. Irrigate the NG tube with sterile water
- C. Turn the client on their side
- D. Replace the NG tube with a new one
Correct answer: B
Rationale: The correct answer is to irrigate the NG tube with sterile water. When a client with an NG tube attached to low suctioning becomes nauseated and there is a decrease in the flow of gastric secretions, it indicates a possible blockage in the tube. Irrigating the tube with sterile water can help clear the blockage, allowing for proper suctioning and relieving the client's nausea. Increasing the suction pressure (Choice A) can further worsen the issue by potentially causing harm to the client. Turning the client on their side (Choice C) may not address the underlying problem of tube blockage. Replacing the NG tube with a new one (Choice D) should only be considered if other interventions, like irrigation, fail to clear the blockage.
3. A nurse is reviewing the laboratory results of a client who is undergoing screening for prostate cancer. The nurse should expect an elevation in which of the following laboratory values?
- A. Prostate-specific antigen (PSA)
- B. Human chorionic gonadotropin (hCG)
- C. Alpha-fetoprotein (AFP)
- D. Carcinoembryonic antigen (CEA)
Correct answer: A
Rationale: The correct answer is A: Prostate-specific antigen (PSA). PSA is a marker specifically used for prostate cancer screening. Elevated levels of PSA can indicate prostate cancer or other prostate-related issues, prompting the need for further diagnostic investigations. Choices B, C, and D are not typically associated with prostate cancer screening. Human chorionic gonadotropin (hCG) is related to pregnancy, alpha-fetoprotein (AFP) is associated with liver and germ cell tumors, and carcinoembryonic antigen (CEA) is linked to colorectal cancer.
4. A nurse is caring for a client who is at 41 weeks of gestation and is receiving oxytocin for labor induction. The nurse notes early decelerations on the fetal heart rate monitor. Which of the following nursing actions should the nurse take?
- A. Continue to monitor the fetal heart rate.
- B. Stop the oxytocin infusion.
- C. Perform a vaginal examination.
- D. Initiate an amnioinfusion.
Correct answer: A
Rationale: The correct action for early decelerations, which are caused by fetal head compression and are considered normal during labor, is to continue monitoring the fetal heart rate. Early decelerations mirror contractions and usually do not require any intervention. Stopping the oxytocin infusion (Choice B) is not necessary as early decelerations are not typically a cause for concern related to oxytocin. Performing a vaginal examination (Choice C) or initiating an amnioinfusion (Choice D) are unnecessary and not indicated specifically for early decelerations.
5. A nurse is teaching a client who is taking warfarin about food and medication interactions. Which of the following foods should the nurse instruct the client to avoid?
- A. Tomatoes
- B. Apples
- C. Broccoli
- D. Green leafy vegetables
Correct answer: D
Rationale: Correct Answer: Green leafy vegetables - Green leafy vegetables are high in vitamin K, which can interfere with the effectiveness of warfarin. Tomatoes, apples, and broccoli are not contraindicated with warfarin therapy. While they are healthy choices, they do not have a significant impact on warfarin's effectiveness.
