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

• A. German Measles
• B. RSV
• C. Meningitis
• D. Whooping Cough

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. Which of the following patients is at the greatest risk for a stroke?

• A. A 60-year-old male who weighs 270 pounds, has atrial fibrillation, and has had a TIA in the past
• B. A 75-year-old male who has frequent migraines, drinks a glass of wine every day, and is Hispanic
• C. A 40-year-old female who has high cholesterol and uses oral contraceptives
• D. A 65-year-old female who is African American, has sickle cell disease, and smokes cigarettes

Correct answer: A

Rationale: The correct answer is the 60-year-old male who has a combination of significant risk factors for stroke, including atrial fibrillation, a history of a transient ischemic attack (TIA), and obesity. These factors greatly increase his risk of stroke. While other choices may have some individual risk factors, they do not collectively pose as high a risk as the patient described in option A. Option B includes migraines and alcohol consumption but lacks other major risk factors seen in option A. Option C mentions high cholesterol and oral contraceptives, which are risk factors but not as significant as atrial fibrillation and a prior TIA. Option D includes smoking and sickle cell disease but lacks the crucial risk factors present in option A.

4. After performing an assessment of an infant with bladder exstrophy, the nurse prepares a plan of care. The nurse identifies which problem as the priority for the infant?

• A. Urinary incontinence
• B. Impaired tissue integrity
• C. Inability to suck and swallow
• D. Lack of knowledge about the disease (parents)

Correct answer: B

Rationale: In bladder exstrophy, the bladder is exposed and external to the body, leading to impaired tissue integrity related to the exposed bladder mucosa as the priority problem. Urinary incontinence is not a concern as the infant is not yet toilet trained. Inability to suck and swallow is unrelated to the disorder. While educating the parents about the condition is important, it is not the priority over addressing the immediate risk of impaired tissue integrity in the infant.

5. A 16-month-old child has just been admitted to the hospital. As the nurse assigned to this child enters the hospital room for the first time, the toddler runs to the mother, clings to her, and begins to cry. What would be the initial action by the nurse?

• A. Arrange to change client care assignments
• B. Explain that this behavior is expected
• C. Discuss the appropriate use of 'time-out'
• D. Explain that the child needs extra attention

Correct answer: B

Rationale: When encountering a 16-month-old child exhibiting fear of strangers by clinging to the parent and crying, it is essential for the nurse to explain that this behavior is expected. Fear of strangers typically emerges around 6-8 months of age and can continue into the toddler years and beyond. This behavior is a normal part of development as the child is displaying attachment and trust in familiar caregivers. Changing client care assignments, discussing 'time-out,' or suggesting the child needs extra attention are not appropriate initial actions in this situation. Changing care assignments is unnecessary and does not address the child's emotional needs. Discussing 'time-out' is not relevant as it pertains to discipline strategies for older children. Suggesting the child needs extra attention may misinterpret the situation; the child's behavior is a normal response to a new environment and does not necessarily indicate a need for additional attention.
