HESI 799 RN Exit Exam Quizlet
1. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding requires immediate intervention?
- A. Peaked T waves on the ECG
- B. Bradycardia
- C. Decreased deep tendon reflexes
- D. Muscle weakness
Correct answer: A
Rationale: Peaked T waves on the ECG are a critical finding in hyperkalemia as they indicate potential life-threatening cardiac arrhythmias. Immediate intervention is necessary to prevent cardiac complications such as ventricular tachycardia or fibrillation. Bradycardia, decreased deep tendon reflexes, and muscle weakness are not typically associated with hyperkalemia and do not pose the same level of immediate risk to the client's life.
2. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which intervention is most important?
- A. Administer insulin as prescribed.
- B. Monitor the client's urine output.
- C. Assess the client's level of consciousness.
- D. Obtain an arterial blood gas (ABG) sample.
Correct answer: A
Rationale: Administering insulin is the most crucial intervention in managing diabetic ketoacidosis. Insulin helps reduce blood glucose levels and correct metabolic acidosis, which are the primary issues in DKA. Monitoring urine output (Choice B) is important but not as critical as administering insulin. Assessing the client's level of consciousness (Choice C) is essential but does not directly address the underlying cause of DKA. Obtaining an arterial blood gas sample (Choice D) can provide valuable information but is not as urgent as administering insulin to address the immediate metabolic imbalance.
3. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?
- A. International Normalized Ratio (INR)
- B. Prothrombin time (PT)
- C. Serum sodium level
- D. Hemoglobin level of 12 g/dl
Correct answer: A
Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.
4. While caring for a toddler receiving oxygen (02) via face mask, the nurse observes that the child's lips and nares are dry and cracked. Which intervention should the nurse implement?
- A. Ask the mother what she usually uses on the child's lips and nose.
- B. Apply a petroleum jelly (Vaseline) to the child's nose and lips.
- C. Use a topical lidocaine (Zylocaine viscous) analgesic for cracked lips.
- D. Use a water-soluble lubricant on affected oral and nasal mucosa.
Correct answer: D
Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.
5. A nurse is caring for a client with Diabetes Insipidus. Which assessment finding warrants immediate intervention by the nurse?
- A. Hypernatremia
- B. Excessive thirst
- C. Elevated heart rate
- D. Poor skin turgor
Correct answer: A
Rationale: The correct answer is A: Hypernatremia. In a client with Diabetes Insipidus, hypernatremia, an elevated sodium level in the blood, can lead to neurological symptoms such as confusion, seizures, or coma. Immediate intervention is necessary to prevent these serious complications. Excessive thirst (choice B) is a common symptom of Diabetes Insipidus but does not require immediate intervention. Elevated heart rate (choice C) and poor skin turgor (choice D) are important assessments but are not as critical as hypernatremia in this context.
