1. The healthcare provider prescribes 1,000 ml of Ringer's Lactate with 30 Units of Pitocin to run over 4 hours for a client who has just delivered a 10-pound infant by cesarean section. The tubing has been changed to a 20 gtt/ml administration set. The LPN/LVN plans to set the flow rate at how many gtt/min?
- A. 42 gtt/min
- B. 83 gtt/min
- C. 125 gtt/min
- D. 250 gtt/min
Correct answer: B
Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) ÷ Time (min) ÷ Drop factor (gtt/mL). In this case, 1000 mL ÷ 240 min ÷ 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.
2. When assessing a client’s heart sounds, the nurse hears a scratching sound during both systole and diastole. These sounds become more distinct when the nurse has the client sit up and lean forward. The nurse should document the presence of a:
- A. Pericardial friction rub
- B. Heart murmur
- C. S3 heart sound
- D. S4 heart sound
Correct answer: A
Rationale: A pericardial friction rub is characterized by a scratching sound that occurs during both systole and diastole. It becomes more distinct when the client is sitting up and leaning forward. This indicates an inflammation of the pericardial sac rubbing against the layers of the heart. Heart murmurs (choice B) are abnormal heart sounds caused by turbulent blood flow, not by friction like in a pericardial rub. S3 and S4 heart sounds (choices C and D) are additional heart sounds related to abnormal ventricular filling, not to pericardial friction rubs.
3. The patient has been brought to the emergency department following a motor vehicle accident. The patient is unresponsive. The driver's license states that glasses are needed to operate a motor vehicle, but no glasses were brought in with the patient. Which action should the nurse take next?
- A. Stand to the side of the patient's eye and observe the cornea.
- B. Conclude that the glasses were lost during the accident.
- C. Notify the ambulance personnel about the missing glasses.
- D. Ask the patient where the glasses are.
Correct answer: A
Rationale: In this scenario, the nurse should stand to the side of the patient's eye and observe the cornea. This action is crucial in assessing whether the patient wears contact lenses, especially in unresponsive patients. Observing the cornea can provide valuable information about the patient's eye health and potential use of contact lenses. Choices B, C, and D are incorrect. Concluding that the glasses were lost during the accident is premature without proper assessment. Notifying ambulance personnel about the missing glasses may not be the immediate priority, and asking the unresponsive patient about the glasses would not yield useful information in this situation.
4. A client with chronic back pain asks a nurse about receiving acupuncture for relief. Which of the following findings should the nurse identify as a contraindication to receiving this treatment?
- A. Obesity
- B. Hypertension
- C. Migraines
- D. Cellulitis
Correct answer: D
Rationale: The correct answer is D, Cellulitis. Cellulitis is a contraindication for acupuncture due to the risk of infection. Acupuncture involves inserting needles into the skin, and if a person has cellulitis, which is a bacterial skin infection, there is a higher risk of introducing the infection deeper into the body. Obesity (choice A), hypertension (choice B), and migraines (choice C) are not contraindications for receiving acupuncture. These conditions do not pose a direct risk of complications related to acupuncture treatment.
5. A client has a prescription for 5 units of regular insulin and 10 units of NPH insulin to mix together and administer subcutaneously. Determine the correct order of steps for this procedure.
- A. Inject 5 units of air into the bottle of regular insulin
- B. Withdraw the correct dose of NPH insulin from the bottle
- C. Inject 10 units of air into the bottle of NPH insulin
- D. Withdraw the correct dose of regular insulin from the bottle
Correct answer: B
Rationale: The correct order of steps for this procedure is to first inject air into the NPH insulin bottle to prevent vacuum formation. After injecting air into the NPH insulin, the next step is to withdraw the correct dose of regular insulin from its bottle. This sequence ensures that the regular insulin is drawn after the NPH insulin, preventing contamination and ensuring accurate dosing. Therefore, choice B is correct. Choices A, C, and D are incorrect because air should be injected into the NPH insulin first, not the regular insulin, and the doses should be withdrawn in the appropriate order to maintain the integrity and potency of each insulin type.
