PN ATI Capstone Proctored Comprehensive Assessment Form A
1. A nurse is reviewing the ABG results of a client with chronic emphysema. Which result suggests the need for further treatment?
- A. PaO2 level of 89 mm Hg
- B. PaCO2 level of 55 mm Hg
- C. HCO3 level of 25 mEq/L
- D. pH level of 7.37
Correct answer: B
Rationale: The correct answer is B. A PaCO2 level of 55 mm Hg is elevated, indicating carbon dioxide retention, a common complication of emphysema that necessitates intervention. Elevated PaCO2 can lead to respiratory acidosis, reflecting inadequate ventilation. Choices A, C, and D are within normal ranges. A PaO2 level of 89 mm Hg is acceptable. An HCO3 level of 25 mEq/L falls within the normal range, suggesting adequate compensation. A pH level of 7.37 is also within the normal range, indicating the client's acid-base balance is maintained.
2. A nurse is caring for a client with a history of heroin use who is intoxicated. Which finding should the nurse expect?
- A. Constricted pupils
- B. Dilated pupils
- C. Increased reflexes
- D. Elevated blood pressure
Correct answer: A
Rationale: The correct answer is A: Constricted pupils. Constricted pupils are a classic sign of opioid intoxication, including heroin. Opioids like heroin cause the pupils to constrict due to their effect on the autonomic nervous system. Dilated pupils, increased reflexes, and elevated blood pressure are not typically associated with opioid intoxication but may be seen with other substances or conditions.
3. A nurse is caring for a 7-month-old infant being treated for severe dehydration. Which finding indicates treatment has been effective?
- A. Skin turgor displays tenting
- B. Flat anterior fontanel
- C. Cool, mottled skin
- D. Hyperpnea
Correct answer: B
Rationale: A flat anterior fontanel indicates improved hydration in infants, as dehydration typically causes sunken fontanels.
4. A nurse is caring for a client with deep vein thrombosis (DVT). Which action should the nurse take?
- A. Position the client with the affected extremity lower than the heart
- B. Administer acetaminophen for pain
- C. Massage the affected extremity every 4 hours
- D. Withhold heparin IV infusion
Correct answer: D
Rationale: Withholding heparin IV infusion is the priority if there is a risk of complications such as bleeding, which must be evaluated before continuing treatment.
5. A client receiving oxytocin IV for labor augmentation is experiencing contractions every 45 seconds. What action should the nurse take?
- A. Discontinue the oxytocin infusion
- B. Increase the oxytocin infusion
- C. Decrease the oxytocin infusion
- D. Maintain the oxytocin infusion
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to discontinue the oxytocin infusion. Contractions occurring every 45 seconds indicate uterine hyperstimulation, which can pose risks to both the client and the fetus. By stopping the oxytocin infusion, the nurse can help prevent further complications. Choices B, C, and D are incorrect because increasing, decreasing, or maintaining the oxytocin infusion can exacerbate the uterine hyperstimulation and increase the risks associated with it.
