ATI Comprehensive Exit Exam 2023 With NGN Quizlet
1. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?
- A. First-degree AV block.
- B. Premature ventricular contraction.
- C. Sinus bradycardia.
- D. Atrial fibrillation.
Correct answer: A
Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.
2. A client with preeclampsia and postpartum hemorrhage is being cared for by a nurse. The nurse should recognize that which of the following medications is contraindicated?
- A. Methylergonovine
- B. Misoprostol
- C. Dinoprostone
- D. Oxytocin
Correct answer: A
Rationale: The correct answer is A, Methylergonovine. Methylergonovine is contraindicated in clients with preeclampsia due to the risk of hypertension. Misoprostol (choice B), Dinoprostone (choice C), and Oxytocin (choice D) are appropriate medications for managing postpartum hemorrhage and are not contraindicated in clients with preeclampsia.
3. A nurse is preparing to administer a dose of digoxin to a client who has heart failure. Which of the following actions should the nurse take prior to administering the medication?
- A. Monitor the client's respiratory rate.
- B. Assess the client's apical pulse.
- C. Review the client's potassium level.
- D. Monitor the client's fluid intake.
Correct answer: B
Rationale: The correct action the nurse should take prior to administering digoxin is to assess the client's apical pulse. Digoxin is known to affect the heart rate, potentially causing bradycardia. Monitoring the client's respiratory rate (Choice A) is not directly related to administering digoxin. Reviewing the client's potassium level (Choice C) is important but not a direct prerequisite for administering digoxin. Monitoring the client's fluid intake (Choice D) is also important but not a specific action to take just before administering digoxin.
4. A nurse is assessing a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the nurse report to the provider?
- A. Blood glucose of 110 mg/dL.
- B. Weight loss of 0.5 kg (1.1 lb) in 24 hours.
- C. WBC count of 6,500/mm3.
- D. Temperature of 37.3°C (99.1°F).
Correct answer: B
Rationale: A weight loss of 0.5 kg (1.1 lb) in 24 hours may indicate dehydration or malnutrition, which are critical concerns for a client receiving total parenteral nutrition (TPN). Therefore, the nurse should report this finding to the provider. Elevated blood glucose levels (Choice A) can be managed by adjusting TPN components, WBC count (Choice C) and a slightly elevated temperature (Choice D) are not directly related to TPN administration and may not require immediate intervention.
5. A healthcare professional is reviewing the laboratory findings of a client who has diabetes mellitus. Which of the following findings indicates a need to revise the client's plan of care?
- A. Serum sodium 144 mEq/L.
- B. HbA1c 10%.
- C. Random serum glucose 190 mg/dL.
- D. Creatinine 1.2 mg/dL.
Correct answer: C
Rationale: Elevated random serum glucose levels of 190 mg/dL indicate hyperglycemia and poor blood sugar control, requiring a revised plan of care. HbA1c levels above 7% also indicate long-term poor control of blood sugar. Serum sodium of 144 mEq/L and creatinine of 1.2 mg/dL are within normal ranges and do not directly indicate a need for a plan of care revision.
