CAT Exam Practice Test
1. A client is admitted to the hospital with a serum sodium level of 128 mEq/L, distended neck veins, and lung crackles. What intervention should the nurse implement?
- A. Increase the intake of salty foods
- B. Administer NaCl supplements
- C. Restrict oral fluid intake
- D. Hold the client's loop diuretic
Correct answer: C
Rationale: In the scenario described, the client presents with signs of fluid overload and hyponatremia. Restricting oral fluid intake is the appropriate intervention to manage fluid overload and correct hyponatremia. Increasing the intake of salty foods (Choice A) and administering NaCl supplements (Choice B) would exacerbate the sodium imbalance. Holding the client's loop diuretic (Choice D) is not directly related to addressing the fluid overload and hyponatremia.
2. Two hours after delivering a 9-pound infant, a client saturates a perineal pad every 15 minutes. Although an IV containing Pitocin is infusing, her uterus remains boggy, even with massage. The healthcare provider prescribes methylergometrine maleate (Methergine) 0.2 mg IM STAT. Which complication should the nurse be alert to this client developing?
- A. Decreased respiratory rate
- B. Increased temperature
- C. Tachycardia
- D. Hypertension
Correct answer: D
Rationale: The correct answer is D: Hypertension. Methylergometrine maleate (Methergine) is a medication used to prevent or control postpartum hemorrhage by causing uterine contractions. One of the potential side effects is hypertension. Therefore, the nurse should closely monitor the client's blood pressure after administering Methergine. Choices A, B, and C are incorrect because Methergine is not known to cause decreased respiratory rate, increased temperature, or tachycardia.
3. A client with leukemia who is receiving myelosuppressive chemotherapy has a platelet count of 25,000/mm3. Which intervention is most important for the nurse to include in this client’s plan of care?
- A. Monitor for signs of activity intolerance
- B. Require visitors to wear respiratory masks
- C. Assess urine and stool for occult blood
- D. Obtain client’s temperature q4 hours
Correct answer: C
Rationale: The correct answer is to assess urine and stool for occult blood. With a low platelet count, there is an increased risk of bleeding. Monitoring for occult blood is essential to detect any signs of internal bleeding. Choices A, B, and D are not the priority interventions in this situation. While monitoring for signs of activity intolerance, requiring visitors to wear respiratory masks, and obtaining the client's temperature are important aspects of care, they are not as critical as assessing for occult blood in a client with a low platelet count.
4. A client is admitted with severe dehydration. What is the most important assessment finding for the nurse to monitor?
- A. Changes in mental status
- B. Urine output and color
- C. Blood pressure and heart rate
- D. Skin turgor
Correct answer: A
Rationale: Changes in mental status are crucial to monitor in a client with severe dehydration. Altered mental status, such as confusion or lethargy, can indicate severe dehydration and potential complications like electrolyte imbalances affecting the brain. Monitoring urine output and color (choice B) is essential but may not provide immediate signs of severe dehydration. While monitoring blood pressure and heart rate (choice C) is important, changes in mental status take precedence as they can indicate more critical conditions. Skin turgor (choice D) is a valuable assessment for dehydration, but changes in mental status take priority due to their direct correlation with severe dehydration.
5. A heparin infusion is prescribed for a client who weighs 220 pounds. After administering a bolus dose of 80 units/kg, the nurse calculates the infusion rate for the heparin sodium at 18 units/kg/hour. The available solution is Heparin Sodium 25,000 units in 5% Dextrose Injection 250 ml. The nurse should program the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: B
Rationale: To calculate the infusion rate, first, find the total dose required per hour, which is the patient's weight (220 pounds) multiplied by the prescribed rate (18 units/kg/hour). This equals 3960 units/hour. Next, determine how many ml of the solution contain 25,000 units; this is 250 ml. Divide the total dose required per hour (3960 units) by the units per ml (25,000 units/250 ml) to find how many ml are needed per hour. This results in 27 ml/hour. Therefore, the nurse should program the infusion pump to deliver 27 ml/hour. Choice A (18) is incorrect as it does not account for the concentration of the heparin solution. Choices C (36) and D (45) are incorrect as they do not reflect the accurate calculations based on the patient's weight and the heparin concentration in the solution.
