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.

What is the most common complication of chest wall injury?
- A. Hemothorax
- B. Atelectasis
- C. Pneumonia
- D. Pneumothorax
Correct Answer: C
Rationale: Pneumonia is the most common complication of chest wall injury. Chest wall trauma can lead to impaired lung function, making patients more susceptible to pneumonia due to reduced ability to clear secretions and impaired breathing. While hemothorax and pneumothorax are potential complications of chest wall injury, pneumonia is more commonly encountered. Atelectasis, although a common pulmonary complication, is not typically the most common complication seen in chest wall injuries.
What nursing intervention demonstrates that the nurse understands the priority nursing diagnosis when caring for oral cancer patients with extensive tumor involvement and/or a high amount of secretions?
- A. The nurse uses a pen pad to communicate with the patient
- B. The nurse provides oral care every 2 hours
- C. The nurse listens for bowel sounds every 4 hours
- D. The nurse suctions as needed and elevates the head of the bed
Correct Answer: D
Rationale: The correct answer is to suction as needed and elevate the head of the bed. This intervention is crucial for managing Ineffective Airway Clearance, which is the priority nursing diagnosis in oral cancer patients with extensive tumor involvement and/or a high amount of secretions. Suctioning helps clear secretions that may obstruct the airway, while elevating the head of the bed promotes optimal respiratory function. Providing oral care every 2 hours may be important for overall oral health but is not directly related to addressing the priority diagnosis. Listening for bowel sounds every 4 hours is more relevant to gastrointestinal assessment and not specific to managing airway clearance issues in oral cancer patients.
A healthcare professional has just received a medication order that is not legible. Which statement best reflects assertive communication?
- A. I cannot give this medication as it is written. I have no idea what you mean.
- B. Would you please clarify what you have written so I am sure I am reading it correctly?
- C. I am having difficulty reading your handwriting. It would save me time if you would be more careful.
- D. Please print in the future so I do not have to spend extra time attempting to read your writing.
Correct Answer: B
Rationale: Assertive communication respects the rights and responsibilities of both parties. Choice B is the best example of assertive communication in this scenario. It addresses the issue directly by requesting clarification without blaming or devaluing the prescriber. This approach shows concern for safe practice and acknowledges the importance of clear communication in healthcare. Choices A, C, and D either involve self-depreciation, blaming the prescriber, or making demands without a respectful request for clarification, making them less effective in promoting effective communication and safe patient care.
While working with an obese adolescent, it is important for the nurse to recognize that obesity in adolescents is most often associated with what other behavior?
- A. Sexual promiscuity
- B. Poor body image
- C. Dropping out of school
- D. Drug experimentation
Correct Answer: B
Rationale: When addressing obesity in adolescents, it is crucial to consider that poor body image is a common behavior associated with obesity. As adolescents gain weight, they may experience a decrease in self-esteem and a negative perception of their body. This can contribute to a cycle of unhealthy behaviors and impact their overall well-being. The other choices are less commonly associated with obesity in adolescents. Sexual promiscuity may be influenced by various factors unrelated to obesity, dropping out of school is more often linked to academic challenges or social issues, and drug experimentation can stem from a range of influences but is not directly correlated with obesity.
A nurse is caring for a 2-year-old child after corrective surgery for Tetralogy of Fallot. The mother reports that the child has suddenly begun seizing. The nurse recognizes this problem is probably due to
- A. A cerebral vascular accident
- B. Postoperative meningitis
- C. Medication reaction
- D. Metabolic alkalosis
Correct Answer: A
Rationale: The correct answer is a cerebral vascular accident. Polycythemia occurs as a physiological reaction to chronic hypoxemia, which commonly occurs in clients with Tetralogy of Fallot. Polycythemia and the resultant increased viscosity of the blood increase the risk of thromboembolic events, including cerebrovascular accidents. Signs and symptoms of a cerebral vascular accident include sudden paralysis, altered speech, extreme irritability or fatigue, and seizures. Postoperative meningitis (choice B) is less likely in this scenario as the sudden onset of seizing is more indicative of a vascular event rather than an infection. Medication reaction (choice C) is not the most probable cause given the history provided. Metabolic alkalosis (choice D) is not associated with sudden seizing in this context.
