1. 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?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/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.

2. A 67-year-old male patient with acute pancreatitis has a nasogastric (NG) tube to suction and is NPO. Which information obtained by the nurse indicates that these therapies have been effective?

• A. Bowel sounds are present.
• B. Grey Turner sign resolves.
• C. Electrolyte levels are normal.
• D. Abdominal pain is decreased.

Correct answer: D

Rationale: The correct answer is 'Abdominal pain is decreased.' In a patient with acute pancreatitis, the goal of using an NG tube for suction and keeping the patient NPO is to decrease the release of pancreatic enzymes and alleviate pain. Therefore, a decrease in abdominal pain would indicate the effectiveness of these therapies. Bowel sounds being present do not necessarily indicate treatment effectiveness, as they can still be present even if the therapies are not fully effective. Normal electrolyte levels are important but do not directly reflect the efficacy of NG suction and NPO status. The resolution of Grey Turner sign, a bruising over the flanks associated with pancreatitis, is a late and non-specific finding and waiting for it to resolve is not a reliable indicator of treatment effectiveness.

3. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client

• A. Has increased airway obstruction
• B. Has improved airway obstruction
• C. Needs to be suctioned
• D. Exhibits hyperventilation

Correct answer: B

Rationale: The higher pitched a sound is, the more narrow the airway. Therefore, the obstruction has increased or worsened. With no evidence of secretions, there is no support to indicate the need for suctioning. Wheezes changing from low-pitched to high-pitched and extending throughout exhalation suggest a progression in airway constriction, indicating an increase in airway obstruction. Option B is incorrect because the change in wheezes from low to high pitch does not suggest an improvement in airway obstruction. Option C is incorrect as there is no indication of secretions requiring suctioning. Option D is incorrect as hyperventilation is not typically associated with the described change in wheezes.

4. A child is diagnosed with a Greenstick Fracture. Which of the following most accurately describes the broken bone?

• A. compound fracture of the fibula
• B. a partial break in a long bone
• C. fracture of the growth plate of the ulna near the wrist
• D. Colles fracture of the tibia

Correct answer: B

Rationale: A Greenstick Fracture is commonly found in children due to their bones being more flexible. This type of fracture occurs when a bone bends and partially breaks, resembling what happens when a green stick from a tree is bent in half. Therefore, the most accurate description of a Greenstick Fracture is 'a partial break in a long bone.' Choice A, 'compound fracture of the fibula,' is incorrect as a Greenstick Fracture is not a compound fracture. Choice C, 'fracture of the growth plate of the ulna near the wrist,' is incorrect as it describes a different type of fracture. Choice D, 'Colles fracture of the tibia,' is incorrect as it refers to a specific type of fracture in a different bone.

5. When caring for a patient hospitalized with active tuberculosis (TB), the nurse observes a student nurse who is assigned to take care of the patient. Which action, if performed by the student nurse, would require an intervention by the nurse?

• A. The patient is offered a tissue from the box at the bedside.
• B. A surgical face mask is applied before visiting the patient.
• C. A snack is brought to the patient from the unit refrigerator.
• D. Hand washing is performed before entering the patient's room.

Correct answer: B

Rationale: When caring for a patient with active tuberculosis (TB), it is crucial to use a high-efficiency particulate-absorbing (HEPA) mask instead of a standard surgical mask when entering the patient's room, as a HEPA mask can filter out 100% of small airborne particles, reducing the risk of transmission. Therefore, if the student nurse applies only a surgical face mask before visiting the patient, this action would require intervention by the nurse to ensure the appropriate protective equipment is used. Hand washing before entering the patient's room is essential to prevent the spread of infection and is a correct action. Bringing a snack to the patient from the unit refrigerator is appropriate and helps address potential issues with anorexia and weight loss in patients with TB. While hand washing after handling a tissue used by the patient is necessary, no special precautions are required when offering the patient an unused tissue.
