HESI CAT Exam Quizlet
1. A client who sustained a pellet gun injury with a resulting comminuted skull fracture is admitted overnight for observation. Which assessment finding obtained two hours after admission necessitates immediate intervention?
- A. The client complains of a throbbing headache rated 10 (on a scale of 1 to 10)
- B. The client repeatedly falls asleep while talking with the nurse
- C. The entry site has a slow trickle of bright red blood
- D. The entry site appears reddened and edematous
Correct answer: B
Rationale: In a client with a pellet gun injury and a comminuted skull fracture, repeatedly falling asleep while talking with the nurse is a concerning sign. It can indicate increased intracranial pressure or a deteriorating condition, requiring immediate intervention. The other options, such as a throbbing headache (choice A), slow trickle of bright red blood at the entry site (choice C), or reddened and edematous entry site (choice D), while important to monitor, do not directly indicate a need for immediate intervention as much as the client falling asleep repeatedly while talking does.
2. A client with a large pleural effusion undergoes a thoracentesis. Following the procedure, which assessment finding warrants immediate intervention by the nurse?
- A. The client has asymmetrical chest wall expansion
- B. The client complains of pain at the insertion site
- C. The client's chest x-ray indicates decreased pleural effusion
- D. The client's arterial blood gases show pH 7.35, PaO2 85, PaCO2 35, HCO3 26
Correct answer: A
Rationale: Asymmetrical chest wall expansion is a critical finding post-thoracentesis as it may suggest a pneumothorax, requiring immediate intervention to prevent further complications. The other options, such as pain at the insertion site (Choice B), decreased pleural effusion on chest x-ray (Choice C), and normal arterial blood gases within acceptable ranges (Choice D) do not indicate an immediate need for intervention like asymmetrical chest wall expansion does.
3. While caring for a client with bilateral chest tubes, the bubbling in the water-seal chamber of the right chest tube stops. What action is most important for the nurse to take?
- A. Check the chest tube connections to the water-seal container
- B. Replace the water-seal collection container
- C. Increase the amount of wall suction connected to the right chest tube
- D. Milk the tubing connected to the right chest tube
Correct answer: A
Rationale: The most important action for the nurse to take when the bubbling in the water-seal chamber of the right chest tube stops is to check the chest tube connections to the water-seal container. This is crucial to ensure there are no disconnections or leaks affecting the bubbling. Replacing the water-seal collection container (choice B) is not necessary unless there is a malfunction; increasing suction (choice C) without assessing the connections can be harmful, and 'milking' the tubing (choice D) is an inappropriate action that can cause damage to the system.
4. After assessing an older adult with a suspected cerebrovascular accident (CVA), the nurse documents the client's right upper arm weakness and slurred speech. When the client complains of a severe headache and nausea, and the neurological assessment remains unchanged, which action should the nurse implement first?
- A. Administer an oral analgesic with antiemetic
- B. Collect blood for coagulation times
- C. Send the client for a computed tomography scan of the brain
- D. Obtain a history of medication use, recent surgery, or injury
Correct answer: C
Rationale: In this scenario, the priority action for the nurse is to send the client for a computed tomography (CT) scan of the brain. A CT scan is crucial in assessing acute changes or bleeding that could influence treatment decisions in a suspected cerebrovascular accident (CVA). While addressing symptoms like headache and nausea is important, ruling out acute changes in the brain with a CT scan takes precedence in this situation. Collecting blood for coagulation times may be necessary but is not the initial priority. Obtaining a history of medication use, recent surgery, or injury is also important but not the first action to take when a CVA is suspected.
5. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.
