CAT Exam Practice Test
1. 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.
2. A female client reports she has not had a bowel movement for 3 days, but now is defecating frequent small amounts of liquid stool. Which action should the nurse implement?
- A. Digitally check the client for a fecal impaction
- B. Increase fluid intake to promote bowel regularity
- C. Provide a high-fiber diet to facilitate bowel movements
- D. Administer a stool softener
Correct answer: A
Rationale: The correct answer is A: Digitally check the client for a fecal impaction. Small, frequent liquid stools following constipation may indicate a fecal impaction. This intervention is crucial to assess and address a potential impaction promptly. Choices B, increasing fluid intake, and C, providing a high-fiber diet, may help with bowel regularity in general cases, but they don't directly address the urgent concern of a possible impaction. Choice D, administering a stool softener, is not appropriate as the first action when a fecal impaction is suspected; it could worsen the condition by causing further liquid stool output without addressing the impaction.
3. An adult client with severe depression was admitted to the psychiatric unit yesterday evening. Although the client used to run a year ago, his spouse states that the client no longer runs but sits and watches television most of the day. Which is most important for the nurse to include in this client’s plan of care for today?
- A. Assist the client in identifying goals for the day
- B. Encourage the client to participate in a team sport for one hour
- C. Schedule the client for a group session that focuses on self-esteem
- D. Help the client develop a list of daily affirmations
Correct answer: A
Rationale: Assisting the client in identifying goals for the day is the most important aspect of the plan of care for a client with severe depression. Setting achievable daily goals helps engage the client in activities and promotes a sense of accomplishment, which can contribute to gradual improvement in their condition. Encouraging participation in team sports may be overwhelming for a client with severe depression as it requires a significant level of energy and motivation that the client may not possess at this time. Group sessions focusing on self-esteem and daily affirmations are beneficial interventions, but they may not have an immediate impact compared to setting achievable daily goals that can provide a sense of purpose and achievement for the client.
4. The healthcare provider believes that a client who frequently requests pain medication may have a substance abuse problem. Which intervention reflects the healthcare provider's value of client autonomy over veracity?
- A. Administer the prescribed analgesic when requested
- B. Refer the client to a substance abuse program
- C. Collaborate with the healthcare provider to provide a placebo
- D. Document the frequency of medication requests
Correct answer: A
Rationale: Administering the prescribed analgesic when requested is the most appropriate intervention that reflects the healthcare provider's value of client autonomy over veracity. This action respects the client's right to manage their pain and avoids deception. Referring the client to a substance abuse program (Choice B) assumes a diagnosis without evidence and does not respect the client's autonomy. Collaborating to provide a placebo (Choice C) would involve deception, which goes against the value of veracity. Documenting the frequency of medication requests (Choice D) is important for the client's care but does not directly address the issue of respecting client autonomy over veracity.
5. The parents of a 6-year-old recently diagnosed with asthma should be taught that the symptom of acute episodes of asthma is due to which physiological response?
- A. Inflammation of the mucous membrane & bronchospasm
- B. Increased mucus production and bronchoconstriction
- C. Allergic reactions and hyperventilation
- D. Airway narrowing and decreased lung capacity
Correct answer: A
Rationale: The correct answer is A: Inflammation of the mucous membrane & bronchospasm. Acute asthma episodes are primarily caused by inflammation of the airways and bronchospasm, which lead to airway obstruction. Increased mucus production and bronchoconstriction (Choice B) are part of the physiological responses in asthma but do not directly cause acute episodes. Allergic reactions and hyperventilation (Choice C) are related to asthma triggers and responses but are not the direct causes of acute episodes. Airway narrowing and decreased lung capacity (Choice D) are consequences of inflammation and bronchospasm but do not explain the physiological response leading to acute asthma episodes.
