1. An older female client has normal saline infusing at 45 mL/hour. She complains of pain at the insertion site of the IV catheter. There is no redness or edema around the IV site. Which action should the nurse take?
- A. Determine which IV medications have recently been administered.
- B. Explain that without redness or edema, there is no need to re-start the IV.
- C. Consult with the healthcare provider about the best location to start a new IV.
- D. Convert the IV to a saline lock and continue to monitor the site.
Correct answer: D
Rationale: Converting the IV to a saline lock and continuing to monitor the site is the correct action in this scenario. When a client complains of pain at the IV insertion site without redness or edema, it may indicate phlebitis or irritation. Replacing the IV may not be necessary if there are no signs of infection or infiltration. Determining the IV medications administered or consulting with the healthcare provider to start a new IV are not immediate actions required for pain management at the insertion site. Therefore, the most appropriate intervention is to convert the IV to a saline lock and closely observe for any changes or complications.
2. A patient is diagnosed with Mycoplasma pneumonia. Which antibiotic will the nurse expect the provider to order to treat this infection?
- A. Azithromycin (Zithromax)
- B. Clarithromycin (Biaxin)
- C. Erythromycin (E-Mycin)
- D. Fidaxomicin (Dificid)
Correct answer: C
Rationale: Erythromycin is the drug of choice for treating Mycoplasma pneumonia. Mycoplasma pneumonia is typically sensitive to macrolide antibiotics, with erythromycin being one of the first-line agents. Azithromycin and clarithromycin are also effective in treating Mycoplasma pneumonia, but erythromycin is specifically mentioned as the drug of choice in this context. Fidaxomicin, on the other hand, is not indicated for the treatment of Mycoplasma pneumonia and is primarily used to treat Clostridium difficile infections.
3. Which of the following is most important for assessing when evaluating the effects of peritoneal dialysis?
- A. Serum potassium levels
- B. Blood pressure
- C. Daily weight
- D. Serum sodium levels
Correct answer: C
Rationale: Daily weight is the most crucial parameter to assess when evaluating the effects of peritoneal dialysis because it directly reflects fluid balance. Peritoneal dialysis involves the removal of excess fluid and waste products from the body. Monitoring daily weight enables the healthcare provider to track changes in fluid status, ensuring that the dialysis treatment is effective. While serum potassium levels, blood pressure, and serum sodium levels are important parameters to monitor in patients undergoing dialysis, they are not as directly indicative of the immediate effects of peritoneal dialysis on fluid balance as daily weight.
4. What should the nurse do before an echocardiogram for a client who has had a myocardial infarction?
- A. Ensuring no food or drink for 4 hours before the procedure
- B. Obtaining informed consent from the client
- C. Assessing for any history of iodine or shellfish allergies
- D. Informing the client about the painless nature and duration of the procedure
Correct answer: D
Rationale: The correct answer is to inform the client that the echocardiogram is a painless procedure that usually takes 30 to 60 minutes to complete. Echocardiography is a noninvasive, risk-free, and pain-free test that uses ultrasound to evaluate the heart's structure and motion. There is no need for special preparation before the procedure. Choices A, B, and C are incorrect because imposing nothing-by-mouth status, obtaining informed consent, and assessing for allergies to iodine or shellfish are not necessary steps before an echocardiogram.
5. A client receives a prescription for 1 liter of lactated Ringer's intravenously to be infused over 6 hours. How many mL/hr should the nurse program the infusion pump to deliver? (Enter numerical value only. If rounding is needed, round to the nearest whole number.)
- A. 167 mL/hr
- B. 200 mL/hr
- C. 83 mL/hr
- D. 111 mL/hr
Correct answer: A
Rationale: The correct infusion rate is 167 mL/hr. This is calculated by dividing the total volume (1000 mL) by the total time (6 hours), resulting in 166.67 mL/hr, which should be rounded to the nearest whole number as 167 mL/hr. This calculation ensures a steady infusion rate over the specified time frame. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation based on the volume and time provided in the prescription.
