ATI PN Comprehensive Predictor 2020
1. A nurse is reviewing the laboratory results for a client who has Cushing's disease. The nurse should expect the client to have an increase in which of the following laboratory values?
- A. Serum glucose level.
- B. Serum calcium level.
- C. Lymphocyte count.
- D. Serum potassium level.
Correct answer: A
Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, there is an excess production of cortisol, leading to hyperglycemia. This results in an increase in serum glucose levels. Choices B, C, and D are incorrect because Cushing's disease does not directly affect serum calcium levels, lymphocyte count, or serum potassium levels.
2. How should a healthcare professional care for a patient with a central venous catheter?
- A. Monitor for infection and change the dressing regularly
- B. Ensure the catheter is patent and flush as needed
- C. Educate the patient on self-care and proper hygiene
- D. Monitor blood glucose levels and administer IV fluids
Correct answer: A
Rationale: Corrected Rationale: Regular monitoring for infection and dressing changes are essential aspects of caring for a patient with a central venous catheter. Infections are a significant risk with these catheters, so vigilant monitoring and timely dressing changes help prevent complications. Choice B is important too, but ensuring catheter patency and flushing are more focused on maintaining the functionality of the catheter rather than infection prevention. Choice C is also important for patient education, but the immediate concern for a healthcare professional is monitoring and preventing infections related to the catheter. Choice D is not directly related to the care of a central venous catheter.
3. A healthcare professional is collecting data from a client who has hypokalemia. Which of the following findings should the healthcare professional expect?
- A. Muscle stiffness
- B. Bradycardia
- C. Hyperreflexia
- D. Muscle weakness
Correct answer: D
Rationale: The correct answer is 'Muscle weakness.' Hypokalemia is characterized by low potassium levels, which can lead to muscle weakness due to impaired muscle function. Choices A, B, and C are incorrect findings associated with other medical conditions and not typically expected in hypokalemia. Muscle stiffness is more commonly associated with conditions like tetany or muscle cramps, bradycardia is more commonly associated with issues like heart block or hypothyroidism, and hyperreflexia is more commonly seen in conditions like hyperthyroidism or spinal cord injuries.
4. Which assessment finding is expected with myxedema?
- A. Increased pulse rate
- B. Decreased temperature
- C. Fine tremors
- D. Weight loss
Correct answer: B
Rationale: Myxedema is characterized by a decreased metabolic rate, leading to manifestations such as decreased temperature. Therefore, the correct assessment finding expected with myxedema is a decreased temperature. Choices A, C, and D are incorrect because myxedema typically presents with a decreased pulse rate, not an increased pulse rate, absence of fine tremors (which are more common in hyperthyroidism), and weight gain rather than weight loss.
5. A nurse is assessing a client who has a calcium level of 8.0 mg/dL. Which of the following findings should the nurse expect?
- A. Constipation
- B. Absent deep-tendon reflexes
- C. Nausea and vomiting
- D. Tingling of the extremities
Correct answer: D
Rationale: Correct! A calcium level of 8.0 mg/dL indicates hypocalcemia. Hypocalcemia can lead to increased neuromuscular excitability, manifesting as tingling of the extremities. Choices A, B, and C are incorrect findings associated with other electrolyte imbalances or conditions and are not typically related to hypocalcemia. Constipation is commonly seen in hypokalemia, absent deep-tendon reflexes are associated with hypermagnesemia, and nausea and vomiting are more indicative of hypercalcemia.
