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. The nurse provides discharge teaching to a client who was recently diagnosed with diabetes mellitus (DM). After receiving the instructions, the client expresses understanding about when, how, and why to take his prescribed medications at home. Which intervention is most important for the nurse to implement?
- A. Review the purpose of medications prescribed for the client to take home with him
- B. Provide the client with a printed list of medications and a schedule for administration
- C. Send a list of medications taken while hospitalized to the client’s healthcare provider
- D. Offer to consult with the pharmacist about resources for reduced-price medications
Correct answer: B
Rationale: Providing the client with a printed list of medications and a schedule for administration is crucial to ensure adherence and understanding of the medication regimen at home. This intervention helps the client follow the prescribed treatment plan accurately. Choice A is not as essential since the client already understands when, how, and why to take the medications. Choice C is not a priority at this point as the client needs information for home medication management. Choice D, while helpful, is not the most important intervention compared to providing a clear list and schedule for medication administration.
3. The nurse is admitting a client from the post-anesthesia unit to the postoperative surgical care unit. Which intervention should the nurse implement first?
- A. Advance to clear liquids as tolerated
- B. Straight catheterization if unable to void
- C. Administer Cefazolin 1 gram IVPQ q6 hours
- D. Obtain a complete blood cell count (CBC) in the morning
Correct answer: B
Rationale: The correct answer is to perform straight catheterization if the client is unable to void. This action is essential to prevent urinary retention and its potential complications following anesthesia. Option A, advancing to clear liquids, is not the priority upon admission as the focus should be on urinary function first. Option C involves administering an antibiotic, which is important but not the immediate priority. Option D, obtaining a CBC, can be done later and is not as crucial as ensuring proper urinary function postoperatively.
4. After an unsuccessful resuscitation attempt, the nurse calls the family of the deceased. The family wishes to see the body before it is taken to the funeral home. Which interventions should the nurse take to prepare the body before the family enters the room? (Select all that apply)
- A. Take out dentures and place them in a labeled cup
- B. Apply a body shroud
- C. Place a small pillow under the head
- D. Gently close the eyes
Correct answer: A
Rationale: The correct interventions for the nurse to prepare the body before the family enters the room include taking out dentures and placing them in a labeled cup. This is essential to ensure the dignity of the deceased and maintain their appearance. Applying a body shroud is not typically done before the family views the body, as it may be more appropriate during preparation for transportation to the funeral home. Placing a small pillow under the head and gently closing the eyes are actions that can be comforting but are not essential preparations for the family viewing.
5. A nurse is preparing to administer an intramuscular (IM) injection to a client. What is the most appropriate site to use for an IM injection in an adult?
- A. Dorsal gluteal muscle
- B. Vastus lateralis muscle
- C. Rectus femoris muscle
- D. Deltoid muscle
Correct answer: B
Rationale: The correct answer is B: Vastus lateralis muscle. The vastus lateralis muscle is a recommended site for IM injections in adults due to its size and accessibility. The dorsal gluteal muscle is not recommended for IM injections in adults due to the proximity to major nerves and blood vessels, increasing the risk of injury. The rectus femoris muscle is not a common site for IM injections in adults. The deltoid muscle is typically used for IM injections in small-volume medications or vaccines, especially in adults.
