Exam Cram NCLEX RN Practice Questions

1. Which of the following can cause coup-contrecoup injuries?

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

2. Which of the following diseases is caused by the Bordetella pertussis bacterium?

Correct answer: D

Rationale: Bordetella pertussis is the bacterium responsible for causing Whooping Cough, also known as pertussis. Meningitis can be caused by various bacteria, but not specifically by Bordetella pertussis. German Measles, also known as Rubella, and RSV (Respiratory Syncytial Virus) are viral infections and are not caused by the Bordetella pertussis bacterium. Therefore, the correct answer is Whooping Cough, caused by Bordetella pertussis.

3. A 45-year-old woman is prescribed ropinirole (Requip) for Parkinson's Disease. The patient is living at home with her daughter. The nurse is most concerned about which side effect of ropinirole?

Correct answer: B

Rationale: The correct answer is 'Sudden dizziness.' Dizziness and orthostatic hypotension are serious adverse effects of ropinirole that can lead to an increased risk of falls. Ropinirole belongs to the drug class of dopamine agonists, which mimic dopamine in the brain (Parkinson's Disease is characterized by a lack of dopamine). 'Slurred speech' is not a common side effect of ropinirole. 'Mask-like facial expression' and 'Stooped posture' are more associated with the progression of Parkinson's Disease itself rather than a side effect of ropinirole.

4. A client was recently diagnosed with diverticulosis. What types of foods should the nurse recommend for this client?

Correct answer: A

Rationale: Diverticulosis is a condition characterized by small protrusions in the intestinal tract. To manage diverticulosis, a high-fiber diet is recommended. Foods rich in fiber help prevent constipation and reduce the risk of inflammation in the intestines. Whole grain cereals are an excellent source of fiber and can aid in maintaining bowel regularity. Eggs, cottage cheese, and fish are not high-fiber foods and may not provide the necessary dietary support for a client with diverticulosis. While protein-rich foods like eggs and fish are beneficial for overall health, they are not the primary recommendation for managing diverticulosis.

5. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.
