PN ATI Capstone Proctored Comprehensive Assessment B Quizlet
1. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following assessment findings requires immediate intervention by the nurse?
- A. Prealbumin level of 20 mg/dL
- B. Weight increase of 2 kg/day
- C. Temperature of 37.6°C
- D. Blood glucose level of 120 mg/dL
Correct answer: B
Rationale: A rapid weight gain of 2 kg/day suggests fluid overload, a possible complication of TPN. This requires immediate intervention to prevent further complications such as pulmonary edema. The other options are not indicative of immediate complications related to TPN. A low prealbumin level may indicate malnutrition but does not require immediate intervention. A slightly elevated temperature and blood glucose level are within normal ranges and do not warrant immediate action.
2. A nurse in the telemetry unit is receiving the laboratory findings for an adult male client who is being treated for a myocardial infarction. Which of the following is an expected finding for the client?
- A. Troponin I (TnI) 8 ng/mL
- B. Brain natriuretic peptide (BNP) 10 ng/L
- C. Alanine aminotransferase (ALT) 45 units/L
- D. High-density lipoprotein (HDL) 75 mg/dL
Correct answer: A
Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.
3. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results 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: A PaCO2 level of 55 mm Hg indicates hypercapnia, which is common in clients with emphysema but may require further treatment if it leads to respiratory acidosis or distress. Elevated PaCO2 levels can indicate inadequate ventilation and impaired gas exchange, potentially leading to respiratory acidosis. The other results fall within normal ranges or compensated values for a client with chronic emphysema and do not necessarily indicate the need for immediate intervention.
4. A client is being educated by a nurse on nutritional intake. Which of the following should the nurse include in the teaching?
- A. Carbohydrates should be at least 45% of your caloric intake
- B. Protein should be at least 55% of your caloric intake
- C. Carbohydrates should be at least 30% of your caloric intake
- D. Protein should be at least 60% of your caloric intake
Correct answer: A
Rationale: Carbohydrates should make up 45-65% of daily caloric intake as they are the body’s main source of energy. This aligns with general dietary recommendations. Choice B is incorrect as protein should typically make up about 10-35% of daily caloric intake, not 55%. Choice C is also incorrect, as carbohydrates should ideally be between 45-65%, not 30%. Choice D is incorrect because protein should generally account for around 10-35% of total caloric intake, not 60%.
5. A nurse is caring for a client who has a prescription for vancomycin 1 g IV every 12 hours. The client is scheduled to have the morning dose at 0700. The nurse should schedule the trough level to be drawn at which of the following times?
- A. 2100
- B. 900
- C. 1300
- D. 1800
Correct answer: D
Rationale: The trough level of vancomycin should be drawn just before the next dose is administered, typically about 30 minutes before the scheduled dose. Since the morning dose is at 0700, the trough level should be drawn at 1800. This timing ensures an accurate measurement of the lowest concentration of the drug in the client's system before the next dose is given. Choice A (2100) is too close to the next dose, choice B (900) is too early, and choice C (1300) is also too far from the next dose.
