CAT Exam Practice Test
1. Following a gunshot wound, an adult client has a hemoglobin level of 4 grams/dl (40 mmol/L SI). The nurse prepares to administer a unit of blood for an emergency transfusion. The client has AB negative blood type and the blood bank sends a unit of type A Rh negative, reporting that there is not type AB negative blood currently available. Which intervention should the nurse implement?
- A. Transfuse Type A negative blood until type AB negative is available.
- B. Recheck the client’s hemoglobin, blood type, and Rh factor.
- C. Administer normal saline solution until type AB negative is available.
- D. Obtain additional consent for the administration of type A negative blood.
Correct answer: A
Rationale: In emergency situations where AB negative blood is unavailable, type A negative blood can be transfused to a patient with AB negative blood type. Type A negative blood is compatible with AB negative blood, making it a suitable option until the correct blood type becomes available. Transfusion of Type A negative blood is crucial to address the severe anemia promptly. Rechecking the client’s hemoglobin, blood type, and Rh factor (Choice B) may delay necessary treatment. Administering normal saline solution (Choice C) is not a substitute for blood transfusion in cases of severe anemia. Obtaining additional consent for the administration of type A negative blood (Choice D) is unnecessary as the situation is emergent and the blood type is compatible.
2. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled, “Amoxicillin (Amoxil) suspension 200 mg/5 ml.” How many ml should the nurse administer every 8 hours? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
- A. 12.5
- B. 7.5
- C. 10.0
- D. 15.0
Correct answer: A
Rationale: To calculate the amount in ml that the nurse should administer every 8 hours, first, determine the amount of amoxicillin needed per dose. 1.5 grams daily divided by 3 doses equals 0.5 grams per dose. Since 0.5 grams is equivalent to 500 mg (1 gram = 1000 mg), and each 5 ml of the suspension contains 200 mg of amoxicillin, the nurse needs to administer (500 mg / 200 mg) * 5 ml = 12.5 ml every 8 hours. Therefore, the correct answer is 12.5 ml. Choices B, C, and D are incorrect because they do not reflect the accurate calculation based on the provided information.
3. A client with a peripherally inserted central catheter (PICC) line has a fever. What client assessment is most important for the nurse to perform?
- A. Observe the PICC line site for inflammation.
- B. Encourage increasing fluid intake.
- C. Monitor blood pressure regularly.
- D. Assess skin turgor for dehydration.
Correct answer: A
Rationale: The correct answer is to observe the PICC line site for inflammation. When a client with a PICC line develops a fever, it could indicate an infection related to the catheter. Assessing the PICC line site for signs of inflammation, such as redness, warmth, swelling, or drainage, is crucial in identifying a potential infection early. Choice B is incorrect because increasing fluid intake is not directly related to assessing a PICC line for infection. Choice C is not the most appropriate assessment in this situation as monitoring blood pressure may not directly help in identifying the cause of the fever. Choice D is unrelated to the assessment of a fever in a client with a PICC line.
4. A client with metastatic breast cancer refuses to participate in a clinical trial and further treatments. Her children ask the nurse to convince their mother to reconsider. How should the nurse respond?
- A. Ask the client if she fully understands the decision she has made with her children present.
- B. Discuss the success of clinical trials and ask the client to consider participating for one month.
- C. Explain to the family that they must accept their mother’s decision.
- D. Explore the client’s decision to refuse treatment and offer support.
Correct answer: D
Rationale: The correct response is to explore the client's decision to refuse treatment and offer support. In this situation, it is crucial for the nurse to respect the client's autonomy and decisions regarding her own health. By exploring the client's reasons for refusal, the nurse can better understand her perspective and provide appropriate support. Option A is incorrect as it focuses on questioning the client in front of her children, potentially pressuring her. Option B is inappropriate as it disregards the client's autonomy and tries to persuade her to participate. Option C is also incorrect as it dismisses the client's decision and fails to address the family's concerns in a supportive manner.
5. Identify the placement of the stapes footplate into the bony labyrinth.
- A. Fenestra vestibuli
- B. Fenestra cochleae
- C. Tympanic membrane
- D. Round window
Correct answer: A
Rationale: The correct answer is A: Fenestra vestibuli. The stapes footplate is placed into the fenestra vestibuli of the bony labyrinth. This structure is also known as the oval window and is located at the junction of the middle ear and inner ear. Choice B, Fenestra cochleae, is incorrect as this opening is also known as the round window and is located near the base of the cochlea. Choice C, Tympanic membrane, is incorrect as it is also known as the eardrum and separates the external ear from the middle ear. Choice D, Round window, is incorrect as it is the opening covered by the secondary tympanic membrane and is important for the dissipation of sound waves in the cochlea.
