ATI PN Comprehensive Predictor 2020 Answers
1. What is the correct way to assess for pitting edema?
- A. Press over the bony area for 5 seconds and release
- B. Press over the skin for 10 seconds and check for discoloration
- C. Press the area and check for the presence of rash
- D. Press the skin and assess for rebound tenderness
Correct answer: A
Rationale: The correct way to assess for pitting edema is to press over a bony area, typically the tibia, for 5 seconds and then release. This allows for the identification of pitting edema, characterized by an indentation that persists for a few seconds. Choice B is incorrect as pitting edema assessment does not involve checking for discoloration. Choice C is incorrect as the presence of a rash is not indicative of pitting edema. Choice D is incorrect as rebound tenderness is a different assessment used for abdominal conditions, not for pitting edema.
2. What is the best dietary recommendation for a patient with chronic kidney disease?
- A. Low-protein diet
- B. High-protein diet
- C. Low-sodium diet
- D. High-sodium diet
Correct answer: A
Rationale: The correct answer is a low-protein diet for a patient with chronic kidney disease. In chronic kidney disease, the kidneys may have difficulty filtering waste products from protein metabolism, leading to a buildup of toxins in the body. Therefore, reducing protein intake can help lessen the workload on the kidneys. Choices B, C, and D are incorrect. A high-protein diet would increase the workload on the kidneys, while a low-sodium diet is beneficial for conditions like hypertension or heart failure but not specifically targeted for chronic kidney disease. A high-sodium diet can worsen fluid retention and hypertension in patients with kidney disease.
3. A healthcare provider is assessing a client who has received a preoperative dose of morphine. Which of the following findings is the priority to report to the provider?
- A. Client reports nausea.
- B. Urinary output of 20 mL/hr.
- C. Oxygen saturation 90%.
- D. Respiratory rate 14/min.
Correct answer: C
Rationale: An oxygen saturation of 90% is below the expected reference range and could indicate respiratory depression, a serious side effect of morphine. This finding requires immediate attention as it may lead to hypoxia. Nausea (choice A) is a common side effect of morphine but does not pose an immediate threat. A urinary output of 20 mL/hr (choice B) may indicate decreased renal perfusion but is not as critical as respiratory compromise. A respiratory rate of 14/min (choice D) is within the normal range and does not suggest immediate danger.
4. How should a healthcare professional respond to a patient with hypokalemia?
- A. Administer potassium supplements and monitor ECG
- B. Restrict fluid intake and provide a high-sodium diet
- C. Monitor sodium levels and provide insulin therapy
- D. Provide calcium supplements and monitor for hyperkalemia
Correct answer: A
Rationale: Hypokalemia is managed by administering potassium supplements to correct the low potassium levels in the body. Monitoring the ECG is essential because low potassium levels can lead to cardiac arrhythmias. Choice B is incorrect as restricting fluid intake and providing a high-sodium diet are not appropriate for managing hypokalemia. Choice C is incorrect because hypokalemia involves low potassium levels, not sodium levels, and insulin therapy does not directly address this issue. Choice D is incorrect as calcium supplements are not indicated for hypokalemia, and monitoring for hyperkalemia is not relevant in this case.
5. What are the key differences between systolic and diastolic heart failure?
- A. Systolic: Reduced ejection fraction; Diastolic: Preserved ejection fraction
- B. Systolic: Preserved ejection fraction; Diastolic: Reduced ejection fraction
- C. Systolic: Right-sided heart failure; Diastolic: Left-sided heart failure
- D. Systolic: Pulmonary congestion; Diastolic: Systemic congestion
Correct answer: A
Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.
