ATI Vital Signs Assessment Questions
Question 1 of 5
The nurse is reviewing venous blood flow patterns. Which of these statements best describes the mechanism(s) by which venous blood returns to the heart?
Correct Answer: A
Rationale: The correct answer is A. Intraluminal valves ensure unidirectional flow toward the heart. These valves prevent backflow and promote blood flow towards the heart. Skeletal muscle contractions (choice B) help propel blood towards the heart, but they do not ensure unidirectional flow. The heart is not a high-pressure system (choice C), and venous return relies more on mechanisms outside the heart. Choice D incorrectly suggests that thoracic and abdominal pressure changes facilitate venous return, but the primary mechanism is the presence of one-way valves in veins.
Question 2 of 5
Mrs. R. is a 92-year-old retired teacher who comes to your clinic accompanied by her daughter. You ask Mrs. R. why she came to your clinic today. She looks at her daughter and doesn't say anything in response to your question. This is an example of which type of challenging patient?
Correct Answer: C
Rationale: The correct answer is C: Silent patient. Mrs. R.'s lack of response to the question despite being asked directly indicates she is a silent patient. This type of patient may be non-communicative due to various reasons such as anxiety, cognitive impairment, or being passive in decision-making. In this case, Mrs. R. may be relying on her daughter to communicate for her. The other choices are incorrect because Mrs. R. is not talkative, angry, or necessarily hearing-impaired based on the information provided. It is important for healthcare providers to recognize and adapt their communication strategies to effectively engage with silent patients.
Question 3 of 5
Dakota is a 14-year-old boy who just noticed a rash at his ankles. There is no history of exposure to ill people or other agents in the environment. He has a slight fever in the office. The rash consists of small, bright red marks. When they are pressed, the red colour remains. What should you do?
Correct Answer: B
Rationale: Correct Answer: B (Consider admitting the patient to the hospital) Rationale: 1. Dakota is a 14-year-old boy with a sudden rash, slight fever, and no known exposure. 2. The rash is non-blanching which indicates a serious underlying condition like meningococcal infection. 3. Meningococcal infection can progress rapidly, leading to life-threatening complications. 4. Hospital admission allows for close monitoring, diagnostic tests, and prompt treatment if needed. Summary of other choices: A: Steroid cream is not appropriate as the rash could be a sign of a serious infection, not just inflammation. C: Relying on reassurance without proper evaluation can delay necessary treatment. D: Following up in 3 days may be too late if the condition worsens rapidly.
Question 4 of 5
When teaching a client how to effectively manage their new medication regimen, the nurse recognizes that the best method of communicating therapeutically with the client is to:
Correct Answer: D
Rationale: The correct answer is D because facing the client while leaning slightly forward shows active listening and engagement, conveying respect and attentiveness. This posture encourages open communication and trust-building. Choice A is incorrect as the visitors' lounge may not provide privacy. Choice B may invade personal space and affect rapport. Choice C may not be appropriate as touch should only be used if culturally acceptable and with consent.
Question 5 of 5
If a patient is supine with knees flexed to 90 degrees and feet flat on the table, how will it be determined if the right femur is longer than the left?
Correct Answer: D
Rationale: The correct answer is D because in supine position with knees flexed to 90 degrees and feet flat on the table, the right knee being anterior to the left knee indicates that the right femur is longer. This is due to the natural anatomical alignment of the femurs in relation to the knees. The other choices (A, B, C) do not accurately reflect the correct method of determining femur length discrepancy in this specific position. Choice A and B focus on the height of the knees, which may not be an accurate indicator of femur length. Choice C refers to the anterior positioning of the left knee, which is not a reliable indicator of femur length discrepancy.
