1. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: D
Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.
2. In the Emergency Department, a female client discloses that she was raped last night. Which question is most important for the nurse to ask?
- A. Does she know the person who raped her?
- B. Has she taken a bath since the rape occurred?
- C. Is the place where she lives a safe place?
- D. Did she report the rape to the police department?
Correct answer: A
Rationale: The most important question for the nurse to ask in this situation is whether the client knows the person who raped her. This question is crucial for assessing additional safety concerns, providing appropriate support, and determining the need for forensic evidence collection. Choices B, C, and D are not as critical in the immediate assessment and response to a rape victim. Asking about bathing, the safety of her home, or reporting to the police may be important but are secondary to identifying the perpetrator for safety and legal reasons.
3. An 18-year-old gravida 1, at 41-weeks gestation, is undergoing an oxytocin (Pitocin) induction and has an epidural catheter in place for pain control. With each of the last three contractions, the nurse notes a late deceleration. The client is repositioned, and oxygen provided, but the late decelerations continue to occur with each contraction. What action should the nurse take first?
- A. Prepare for immediate cesarean birth
- B. Turn off the oxytocin (Pitocin) infusion
- C. Notify the anesthesiologist that the epidural infusion needs to be disconnected
- D. Apply an internal fetal monitoring device and continue to monitor carefully
Correct answer: B
Rationale: In the scenario described, the nurse notes late decelerations during contractions despite repositioning and oxygen administration. Late decelerations are often associated with uteroplacental insufficiency, which can be exacerbated by increased uterine activity stimulated by oxytocin. The initial action to manage late decelerations is to turn off the oxytocin infusion to reduce uterine stimulation. This step aims to improve fetal oxygenation and prevent further stress on the fetus. Immediate cesarean birth may be necessary if the late decelerations persist or worsen despite discontinuing the oxytocin infusion. Notifying the anesthesiologist to disconnect the epidural infusion or applying an internal fetal monitoring device are not the first-line interventions for managing late decelerations.
4. Following an open reduction and internal fixation of a compound fracture of the leg, a male client complains of “a tingly sensation” in his left foot. The nurse determines the client’s left pedal pulses are diminished. Based on these findings, what is the client’s greatest risk?
- A. Reduce pulmonary ventilation and oxygenation related to fat embolism.
- B. Neurovascular and circulation compromise related to compartment syndrome.
- C. Wound infection and delayed healing due to fractured bone protrusion.
- D. Venous stasis and thrombophlebitis related to postoperative immobility.
Correct answer: B
Rationale: The correct answer is B. Compartment syndrome is a serious condition that can occur following trauma or surgery, leading to compromised neurovascular status in the affected limb. Symptoms include pain, paresthesia (tingling sensation), and diminished pulses. If left untreated, compartment syndrome can result in tissue damage and potential loss of limb function. Options A, C, and D are incorrect because they do not directly address the neurovascular compromise associated with compartment syndrome.
5. An older client is having photocoagulation for macular degeneration. What intervention should the nurse implement during post-procedure care in the outpatient surgical unit?
- A. Apply bilateral eye patches while sleeping
- B. Use a whiteboard to communicate with the client
- C. Arrange food on the plate in a clockwise order
- D. Verbally identify oneself when entering the room
Correct answer: A
Rationale: The correct intervention is to apply bilateral eye patches while sleeping. This measure helps protect the eyes and support healing following photocoagulation for macular degeneration. Choice B is incorrect as using a whiteboard is not directly related to post-procedure care for this intervention. Choice C is incorrect as arranging food on the plate in a clockwise order is not relevant to the post-procedure care of photocoagulation. Choice D is incorrect as verbally identifying oneself when entering the room is important for communication but not specific to the post-procedure care in this scenario.
