CAT Exam Practice
1. Which medication should the nurse anticipate administering to a client who is diagnosed with myxedema coma?
- A. Intravenous administration of thyroid hormones
- B. Oral administration of hypnotic agents
- C. Intravenous bolus of hydrocortisone
- D. Subcutaneous administration of vitamin K
Correct answer: A
Rationale: The correct answer is A: Intravenous administration of thyroid hormones. Myxedema coma is a severe form of hypothyroidism that necessitates immediate replacement of thyroid hormones. Administering thyroid hormones intravenously ensures rapid absorption and effectiveness in managing the condition. Choice B, oral administration of hypnotic agents, is incorrect as it does not address the primary issue of thyroid hormone deficiency in myxedema coma. Choice C, intravenous bolus of hydrocortisone, is not the appropriate treatment for myxedema coma as adrenal insufficiency is not the primary concern in this condition. Choice D, subcutaneous administration of vitamin K, is unrelated to the management of myxedema coma and does not address the underlying thyroid hormone deficiency that characterizes this condition.
2. An adult male is admitted to the intensive care unit because he experienced a sudden onset of sharp chest pain and shortness of breath earlier today. Following an emergent pulmonary angiogram, the client is diagnosed with a pulmonary embolism. Which intervention is most important for the nurse to include in this client’s plan of care?
- A. Monitor signs of increased bleeding
- B. Instruct on the use of incentive spirometry
- C. Observe for confusion and restlessness
- D. Administer intravenous opioids for severe pain
Correct answer: A
Rationale: In a patient diagnosed with a pulmonary embolism, the most critical intervention is to monitor for signs of increased bleeding. Pulmonary embolism treatment often involves anticoagulation therapy, which increases the risk of bleeding. Monitoring for signs of bleeding such as bruising, petechiae, hematuria, or gastrointestinal bleeding is essential to prevent complications. Instructing on the use of incentive spirometry can be beneficial for preventing pulmonary complications but is not as urgent as monitoring for bleeding. Observing for confusion and restlessness may indicate hypoxia but is not the most crucial intervention in this scenario. Administering intravenous opioids for severe pain might be necessary but is not the priority compared to monitoring for bleeding, which is directly related to the treatment for pulmonary embolism.
3. A client with bipolar disorder is prescribed valproic acid (Depakote). What is the most important laboratory test for the LPN/LVN to monitor?
- A. Liver function tests.
- B. Kidney function tests.
- C. Thyroid function tests.
- D. Complete blood count.
Correct answer: A
Rationale: The correct answer is A: Liver function tests. Monitoring liver function tests is crucial for clients prescribed valproic acid (Depakote) due to the medication's potential to affect liver function and increase the risk of liver toxicity. While kidney function tests (choice B), thyroid function tests (choice C), and complete blood count (choice D) are important in various clinical scenarios, the priority when administering valproic acid is to monitor liver function to prevent adverse effects associated with this medication.
4. During an integumentary assessment for a group of clients, a healthcare professional notes various skin findings. Which of the following findings should the professional recognize as requiring immediate intervention?
- A. Pallor
- B. Cyanosis
- C. Jaundice
- D. Erythema
Correct answer: B
Rationale: Cyanosis, a bluish discoloration of the skin, indicates inadequate oxygenation and requires immediate intervention. It suggests a severe lack of oxygen in the blood, which can be life-threatening. Pallor and jaundice are concerning findings but may not indicate an immediate life-threatening situation. Pallor can be a sign of anemia or low blood pressure, while jaundice may indicate liver dysfunction. Erythema, which is redness of the skin, is typically not an emergency and can be caused by various factors such as inflammation or increased blood flow to the area.
5. The nurse is caring for a client who is 4 hours post-operative from abdominal surgery. The client is complaining of severe pain. What is the nurse's first action?
- A. Reassess the pain and its characteristics
- B. Administer prescribed pain medication
- C. Notify the surgeon
- D. Encourage the use of relaxation techniques
Correct answer: A
Rationale: The correct first action for the nurse to take when a post-operative client complains of severe pain is to reassess the pain and its characteristics. Reassessment is crucial to understand the nature and intensity of the pain, which will guide the nurse in providing appropriate interventions. Administering pain medication may be necessary but should only be done after reassessment to ensure the right medication and dose are given. Notifying the surgeon may be required in certain situations, but reassessment of pain should precede this action. Encouraging relaxation techniques is not the priority when a client is experiencing severe pain post-operatively.
