CAT Exam Practice Test
1. While changing a client’s chest tube dressing, the nurse notes a crackling sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?
- A. Apply a pressure dressing around the chest tube insertion site
- B. Assess the client for allergies to topical cleaning agents
- C. Measure the area of swelling and crackling
- D. Administer an oral antihistamine per PRN protocol
Correct answer: A
Rationale: A crackling sensation indicates subcutaneous emphysema, caused by air trapped under the skin. Applying a pressure dressing around the chest tube insertion site can help manage the issue by preventing further air leakage into the tissues. Choice B is incorrect because the crackling sensation is not related to allergies. Choice C is incorrect as measuring the area does not address the underlying cause. Choice D is incorrect as administering an oral antihistamine is not indicated for subcutaneous emphysema.
2. The unlicensed assistive personnel (UAP) has applied a gown and gloves and secured the tops of the gloves over the gown sleeves. What action should the nurse take?
- A. Confirm that the gown is tied securely at the neck and waist
- B. Remind the UAP to wash hands frequently while in the room
- C. Assist the UAP with application of the face mask or face shield
- D. Help the UAP reposition the gown sleeve over the gloves edges
Correct answer: D
Rationale: Proper application of personal protective equipment (PPE) is crucial to maintain infection control. In this scenario, the nurse should help the UAP reposition the gown sleeve over the gloves' edges. This action ensures that the gown properly covers the gloves, reducing the risk of contamination. Choices A, B, and C are incorrect because the primary concern is to address the improper application of PPE by repositioning the gown sleeves over the gloves, not checking other aspects of PPE or reminding about hand hygiene.
3. Two days after an abdominal hysterectomy, an elderly female with diabetes has a syncopal episode. The nurse determines that her vital signs are within normal limits, but her blood sugar is 325 mg/dL or 18.04 mmol/L (SI). What intervention should the nurse implement first?
- A. Administer regular insulin per sliding scale
- B. Cancel the client's dinner tray
- C. Give the client 4 ounces (120 mL) of orange juice
- D. Administer the next scheduled dose of metformin
Correct answer: A
Rationale: In this case, the nurse should implement the intervention of administering regular insulin per sliding scale. High blood sugar levels, as indicated by a reading of 325 mg/dL, require insulin administration to prevent complications such as hyperglycemia. Canceling the client's dinner tray (choice B) would not address the immediate need to lower the blood sugar level. Giving the client orange juice (choice C) might further increase the blood sugar level as it contains sugar. Administering the next scheduled dose of metformin (choice D) is not appropriate as metformin is not typically used for acute management of high blood sugar levels.
4. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: D
Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.
5. An adult client presents to the clinic with large draining ulcers on both lower legs that are characteristic of Kaposi’s Sarcoma lesions. The client is accompanied by two family members. What action should the nurse take?
- A. Obtain a blood sample to determine if the client is HIV positive
- B. Send the family to the waiting area while conducting a head-to-toe assessment
- C. Complete a head-to-toe assessment to identify other signs of HIV
- D. Ask the family members to wear gloves when touching the client
Correct answer: C
Rationale: In this scenario, the most appropriate action for the nurse to take is to complete a head-to-toe assessment to identify other signs of HIV. Kaposi’s Sarcoma is commonly associated with HIV infection, and conducting a comprehensive assessment can provide crucial information on potential signs and symptoms related to HIV. This information is essential for providing appropriate care and treatment. Option A is not the priority at this moment, as the focus should be on assessing the client comprehensively first. Sending the family members away (Option B) may not be necessary if they are not interfering with the assessment process. While infection control is important, asking the family members to wear gloves (Option D) is not the most critical action to take in this situation.
