CAT Exam Practice
1. A continuous infusion of nitroglycerin is prescribed for an adult male admitted with an acute myocardial infarction. The client is experiencing active chest pain that he describes as 8 out of 10. Which intervention is most important for the nurse to implement?
- A. Administer the infusion via an infusion pump
- B. Obtain the current serum potassium level
- C. Continuously monitor blood pressure
- D. Teach guided imagery to decrease pain
Correct answer: C
Rationale: Continuously monitoring blood pressure is crucial in this case because nitroglycerin can cause hypotension as a side effect. Monitoring blood pressure allows the nurse to assess the client's response to the medication and detect any signs of hypotension promptly. This intervention is essential to ensure the effectiveness of nitroglycerin therapy and prevent potential complications. Administering the infusion via an infusion pump is important for accurate dosing but not the most critical at this moment. Obtaining the current serum potassium level is important but not the most immediate concern when the client is experiencing active chest pain. Teaching guided imagery may be beneficial for pain management, but in this scenario, monitoring blood pressure takes precedence due to the potential side effects of nitroglycerin.
2. The nurse is obtaining the medical histories of new clients at a community-based primary care clinic. Which individual has the highest risk for experiencing elder abuse?
- A. A 69-year-old widowed female who lives alone and volunteers at a school
- B. A 95-year-old ambulatory male who resides in a nursing home in a small town
- C. A 78-year-old female on a fixed income who lives with her relatives
- D. An 81-year-old male with diabetes who lives with his wife of 52 years
Correct answer: C
Rationale: Elder abuse risk is higher in individuals who live with relatives and are on a fixed income as these factors can contribute to vulnerability. Living with relatives may expose the individual to potential abusive situations within the family dynamics. Additionally, being on a fixed income may limit financial independence and increase dependency on others, potentially leading to financial abuse. The other options, such as living alone and volunteering, residing in a nursing home, or living with a long-term spouse, do not inherently pose the same level of risk factors for elder abuse as living with relatives on a fixed income.
3. A client receives a prescription for acetylcysteine (Mucomyst) 1.4 grams per nasogastric tube q4 hours. Acetylcysteine is available as a 10% solution (10 grams/100ml). How many ml of the 10% solution should the nurse administer per dose?
- A. 7
- B. 10
- C. 14
- D. 1.4 grams of acetylcysteine is equivalent to 14 ml of a 10% solution.
Correct answer: D
Rationale: To determine the amount of the 10% acetylcysteine solution to administer, convert the 1.4 grams to milligrams (1.4 grams = 1400 mg). Then, as the 10% solution contains 10 grams (10,000 mg) per 100 ml, it means there are 1000 mg of acetylcysteine in every 10 ml of the solution (10,000 mg / 100 ml = 100 mg/ml). Therefore, to administer 1400 mg (1.4 grams) of acetylcysteine, the nurse should give 14 ml of the 10% solution. Choices A, B, and C are incorrect as they do not accurately convert the amount of acetylcysteine to the corresponding volume of the 10% solution.
4. When attempting to establish risk reduction strategies in a community, the nurse notes that regional studies indicate a high number of persons with growth stunting and irreversible mental deficiencies caused by hypothyroidism (cretinism). The nurse should seek funding to implement which screening measure?
- A. T3 levels in school-aged children
- B. T4 levels in newborns
- C. TSH levels in women over 45
- D. Iodine levels in all persons over 60
Correct answer: B
Rationale: Screening T4 levels in newborns is crucial as it helps in the early detection of hypothyroidism, which can prevent conditions like cretinism. Checking T3 levels in school-aged children (Choice A) is not the most appropriate measure for early detection of hypothyroidism in newborns. Monitoring TSH levels in women over 45 (Choice C) is not directly related to detecting hypothyroidism in newborns. Additionally, monitoring iodine levels in all persons over 60 (Choice D) is not specifically aimed at early detection of hypothyroidism in newborns, which is crucial to prevent cretinism.
5. In a client in her third trimester of pregnancy, an S3 heart sound is auscultated. What intervention should the nurse take?
- A. Notify the healthcare provider
- B. Limit the client’s fluids
- C. Prepare the client for an echocardiogram
- D. Document in the client’s record
Correct answer: D
Rationale: An S3 heart sound can be a normal finding in pregnancy due to increased blood volume and flow. In this scenario, there is no immediate need for further interventions. Documenting this finding in the client's record is essential for tracking the client's health status and ensuring proper follow-up if needed. Notifying the healthcare provider, limiting fluids, or preparing for an echocardiogram is unnecessary as it is likely a physiological finding in pregnancy. These interventions should only be considered if other symptoms suggestive of a cardiac issue are present.
