PN ATI Comprehensive Predictor
1. A nurse is caring for an infant who is receiving IV fluids for dehydration. Which of the following should the nurse recognize as a positive response to the therapy?
- A. Tachycardia
- B. Hypotension
- C. Increased urine output
- D. Diarrhea
Correct answer: C
Rationale: Increased urine output is a positive sign that the IV fluids are effectively treating dehydration. Tachycardia (choice A) and hypotension (choice B) are signs of dehydration and would not be considered positive responses to therapy. Diarrhea (choice D) can worsen dehydration and is not a positive response to IV fluid therapy.
2. A nurse is caring for a client who has diabetes mellitus and is experiencing hypoglycemia. Which of the following findings should the nurse expect?
- A. Bradycardia
- B. Tachycardia
- C. Hypotension
- D. Diaphoresis
Correct answer: A
Rationale: Corrected Rationale: Bradycardia is a common sign of hypoglycemia due to the body's response to low blood sugar. During hypoglycemia, the body releases epinephrine, leading to sympathetic nervous system activation. This can result in bradycardia as a compensatory mechanism to preserve glucose for vital organs such as the brain. Tachycardia, hypotension, and diaphoresis are more commonly associated with hypoglycemia when it progresses to severe stages and the body's compensatory mechanisms are overwhelmed.
3. A client with chronic renal failure is prescribed epoetin alfa (Epogen). Which outcome indicates that the medication is effective?
- A. Increased urine output.
- B. Decreased blood pressure.
- C. Improved hemoglobin levels.
- D. Stable potassium levels.
Correct answer: C
Rationale: Epoetin alfa is a medication that stimulates red blood cell production. Therefore, in a client with chronic renal failure, an effective outcome of epoetin alfa therapy would be an improvement in hemoglobin levels. This indicates that the medication is working as intended by addressing anemia, a common complication of chronic renal failure. Increased urine output (choice A) is not directly related to the action of epoetin alfa. Decreased blood pressure (choice B) is not a primary expected outcome of epoetin alfa therapy. Stable potassium levels (choice D) are important but not a direct indicator of the effectiveness of epoetin alfa in this context.
4. After returning the client to bed following a cardiac catheterization procedure with the left femoral vessel as the access site, the nurse places a sign above the bed instructing the client to remain on bed rest and in which position?
- A. In semi-Fowler's position
- B. With the head of the bed elevated 45 degrees
- C. With the head of the bed elevated no more than 15 degrees
- D. With the foot of the bed elevated as much as tolerated by the client
Correct answer: C
Rationale: After cardiac catheterization via the femoral vessel, it is crucial to keep the head of the bed elevated no more than 15 degrees to prevent bleeding at the access site. This position helps maintain pressure on the femoral artery, reducing the risk of bleeding and complications post-procedure. Choices A, B, and D are incorrect because they do not provide the necessary pressure on the femoral artery to prevent bleeding, which is essential after a cardiac catheterization procedure with a femoral access site.
5. A client has been taking propranolol. Which of the following findings indicates a need to withhold the medication?
- A. Sodium 130 mEq/L
- B. Blood pressure 156/90 mm Hg
- C. Potassium 5.2 mEq/L
- D. Pulse 54/min
Correct answer: D
Rationale: A pulse of 54/min indicates bradycardia, which is a side effect of propranolol, a beta-blocker. The medication should be withheld if the client's pulse drops below 60/min. The other findings (sodium levels, blood pressure, and potassium levels) are not directly indicative of the need to withhold propranolol.
