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. When administering a-interferon and ribavirin (Rebetol) to a patient with chronic hepatitis C, the nurse should monitor for which complication?
- A. Leukopenia.
- B. Hypokalemia.
- C. Polycythemia.
- D. Hypoglycemia.
Correct answer: B
Rationale: When administering a-interferon and ribavirin (Rebetol) for chronic hepatitis C, the nurse should monitor for hypokalemia. This combination therapy is known to cause leukopenia, not polycythemia or hypoglycemia. Hypokalemia is a common electrolyte imbalance that can occur with these medications, making it the correct answer to monitor for in this case.
3. Which of these clients is likely to receive sublingual morphine?
- A. A 75-year-old woman in a hospice program
- B. A 40-year-old man who just had throat surgery
- C. A 20-year-old woman with trigeminal neuralgia
- D. A 60-year-old man who has a painful incision
Correct answer: A
Rationale: The correct answer is a 75-year-old woman in a hospice program. Sublingual morphine is commonly used in hospice care because patients may have difficulty swallowing, and intravenous access can be uncomfortable and not ideal for palliative care. Choice B, a 40-year-old man who just had throat surgery, is less likely to receive sublingual morphine as he may be able to swallow, and other pain management options may be more suitable. Choice C, a 20-year-old woman with trigeminal neuralgia, would typically require specific medications targeting neuropathic pain rather than sublingual morphine. Choice D, a 60-year-old man with a painful incision, may benefit from localized pain relief or other systemic pain management options, but sublingual morphine is not usually the first choice for this type of pain.
4. During an assessment of a client with cardiomyopathy, the nurse finds that the systolic blood pressure has decreased from 145 to 110 mm Hg and the heart rate has risen from 72 to 96 beats per minute, and the client complains of periodic dizzy spells. The nurse instructs the client to:
- A. Increase fluids that are high in protein
- B. Restrict fluids
- C. Force fluids and reassess blood pressure
- D. Limit fluids to non-caffeine beverages
Correct answer: D
Rationale: In this scenario, the client with cardiomyopathy is exhibiting signs of orthostatic hypotension, which is characterized by a significant drop in systolic blood pressure (>15 mm Hg) and an increase in heart rate (>15%), along with dizziness. These symptoms suggest volume depletion, inadequate vasoconstrictor mechanisms, and autonomic insufficiency. The appropriate nursing intervention in this case is to force fluids and reassess blood pressure to address the underlying issue of volume depletion and improve hemodynamic stability. Choices A, B, and D are incorrect because increasing fluids high in protein, restricting fluids, or limiting fluids to non-caffeine beverages are not appropriate actions for a client experiencing orthostatic hypotension and signs of volume depletion.
5. A patient who was admitted the previous day with pneumonia complains of a sharp pain of 7 (based on a 0 to 10 scale) whenever taking a deep breath. Which action will the nurse take next?
- A. Auscultate breath sounds.
- B. Administer PRN morphine.
- C. Have the patient cough forcefully.
- D. Notify the patient's healthcare provider.
Correct answer: A
Rationale: The patient's complaint of sharp pain when taking a deep breath is concerning for pleurisy or pleural effusion. The nurse should auscultate breath sounds to assess for a pleural friction rub or decreased breath sounds, which could indicate these conditions. It is crucial to gather assessment data before initiating any pain medications. Asking the patient to cough forcefully may exacerbate the pain and should be avoided until further assessment. Contacting the healthcare provider should be based on the assessment findings; therefore, it is premature to notify the provider without conducting a thorough assessment first.
