Nursing Elites

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 diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

3. The nurse is collecting data on a child recently diagnosed with glomerulonephritis. Which question to the mother should elicit data associated with the cause of this disease?

• A. ''Has your child had any nausea or diarrhea?''
• B. ''Have you noticed any rashes on your child?''
• C. ''Did your child recently complain of a sore throat?''
• D. ''Did your child sustain any injuries to the kidney area?''

Correct answer: C

Rationale: The correct answer is 'Did your child recently complain of a sore throat?' Group A beta-hemolytic streptococcal infection is a known cause of glomerulonephritis. In this condition, the child typically becomes ill with streptococcal infection of the upper respiratory tract, and then after 1 to 2 weeks, symptoms of acute poststreptococcal glomerulonephritis can develop. This question aims to gather crucial information related to a potential trigger for glomerulonephritis. Choices A, B, and D are incorrect because they do not pertain to a common cause or associated symptom of glomerulonephritis.

4. Which goal has the highest priority in the plan of care for a 26-year-old homeless patient admitted with viral hepatitis who has severe anorexia and fatigue?

• A. Increase activity level.
• B. Maintain adequate nutrition
• C. Establish a stable environment
• D. Identify sources of hepatitis exposure

Correct answer: B

Rationale: The highest priority outcome is to maintain adequate nutrition because it is essential for hepatocyte regeneration. In viral hepatitis, the liver is affected, and proper nutrition supports the liver's function and regeneration. While increasing activity level and establishing a stable environment are important, they are not as urgent as ensuring the patient receives proper nutrition. Identifying sources of hepatitis exposure can help prevent future infections, but in the acute phase, the immediate focus should be on providing adequate nutrition to support the patient's recovery.

5. A 53-year-old patient is being treated for bleeding esophageal varices with balloon tamponade. Which nursing action will be included in the plan of care?

• A. Instruct the patient to cough every hour
• B. Monitor the patient for shortness of breath
• C. Verify the position of the balloon every 4 hours
• D. Deflate the gastric balloon if the patient reports nausea

Correct answer: B

Rationale: The correct nursing action for a patient with balloon tamponade for bleeding esophageal varices is to monitor the patient for shortness of breath. The most common complication of balloon tamponade is aspiration pneumonia. Additionally, if the gastric balloon ruptures, the esophageal balloon may slip upward and occlude the airway. Instructing the patient to cough every hour is incorrect as coughing increases the pressure on the varices and raises the risk of bleeding. Verifying the position of the balloon every 4 hours is unnecessary as it is typically done after insertion. Deflating the gastric balloon if the patient reports nausea is incorrect because deflating it may cause the esophageal balloon to occlude the airway, leading to complications. Therefore, monitoring for signs of respiratory distress is crucial in this situation.
