HESI CAT Exam

HESI LPN

1. The healthcare provider prescribes lidocaine (Lidoject-1) 100 mg IV push for ventricular tachycardia for an unconscious client. What is the nurse's priority intervention?

A. Measure the client's cardiac output
B. Assess neurological status q15 min
C. Collect a blood specimen for serum potassium
D. Infuse lidocaine (Lidoject-1) at 20 to 50 mg/min

Correct answer: B

Rationale: The priority intervention for the nurse is to assess the client's neurological status q15 min. This is crucial to monitor for potential side effects of lidocaine, especially its neurotoxic effects. While measuring the client's cardiac output and collecting a blood specimen for serum potassium are important assessments, assessing the neurological status is the priority when administering lidocaine. Infusing lidocaine at a specific rate should follow the initial assessment of the client's neurological status to ensure safety.

2. A client has a history of vasovagal attacks resulting in brady-dysrhythmias. Which instruction is most important to include in the teaching plan?

A. Use stool softeners regularly
B. Avoid electromagnetic fields
C. Maintain a low-fat diet
D. Do not use aspirin products

Correct answer: A

Rationale: The correct answer is A: 'Use stool softeners regularly.' Vasovagal attacks can be triggered by straining, and using stool softeners can help prevent such attacks. Choices B, C, and D are not directly related to preventing vasovagal attacks in this context. Avoiding electromagnetic fields, maintaining a low-fat diet, or not using aspirin products are important for various health reasons but not specifically for preventing vasovagal attacks related to brady-dysrhythmias.

3. When admitting a client diagnosed with active tuberculosis to isolation, which infection control measures should the nurse implement?

A. Negative pressure environment
B. Contact precautions
C. Droplet precautions
D. Protective environment

Correct answer: A

Rationale: The correct answer is A: Negative pressure environment. Tuberculosis is transmitted through airborne particles, so a negative pressure room is essential to prevent the spread of the bacteria. Choice B, contact precautions, are used for infections spread by direct or indirect contact, not for tuberculosis. Choice C, droplet precautions, are for infections transmitted through respiratory droplets, not airborne particles like tuberculosis. Choice D, protective environment, is used for protecting immunocompromised patients from outside pathogens, not for preventing the spread of tuberculosis.

4. Following the evacuation of a subdural hematoma, an older adult develops an infection. The client is transferred to the neuro intensive care unit with a temperature of 101.8 F (39.3 C) axillary, pulse of 180 beats/minute, and a blood pressure of 90/60 mmHg. What is the priority intervention to include in this client’s plan of care?

A. Confusion
B. Check neuro vital signs every 4 hours.
C. Maintain intravenous access.
D. Keep the suture line clean and dry.

Correct answer: C

Rationale: The priority intervention for the client in this scenario is to maintain intravenous (IV) access. Given the client's condition with infection, elevated temperature, tachycardia, and hypotension, it is crucial to ensure IV access for administering antibiotics, fluids, and other medications promptly. This can help manage the infection, stabilize hemodynamics, and support the client's hydration and medication needs. Checking neuro vital signs, although important, is secondary to addressing the immediate need for IV access. Keeping the suture line clean and dry is important for wound care but not the priority when dealing with a systemic infection and hemodynamic instability.

5. The nurse is caring for a newborn who arrives in the nursery following a precipitous birth on the way to the hospital. A drug screen of the mother reveals the presence of cocaine metabolites. The infant has a heart rate of 175 beats/minute, cries continuously, is irritable, and is hyperreactive to stimuli. Which intervention is most important for the nurse to include in this infant’s plan of care?

A. Initiate infant sepsis protocol
B. Implement seizure precautions
C. Refer to protective child services
D. Formula feed every 3 hours

Correct answer: B

Rationale: The infant's symptoms, such as a high heart rate, continuous crying, irritability, and hyperreactivity, suggest possible withdrawal effects due to maternal cocaine use. These symptoms can lead to seizures. Therefore, the priority intervention is to implement seizure precautions to ensure the infant's safety. Initiating the infant sepsis protocol is not indicated based on the symptoms presented. Referring to protective child services is important but not the immediate priority. Formula feeding every 3 hours is a routine care measure but does not address the urgent need to prevent potential seizures.
