1. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?
- A. 100 mL/hour.
- B. 125 mL/hour.
- C. 133 mL/hour.
- D. 150 mL/hour.
Correct answer: C
Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.
2. Which other congenital defects are common in children with Down syndrome?
- A. Hypospadias
- B. Pyloric stenosis
- C. Heart defects
- D. Hip dysplasia
Correct answer: C
Rationale: The correct answer is C: Heart defects. Many children with Down syndrome are born with congenital heart defects. These heart abnormalities are more prevalent in individuals with Down syndrome than in the general population. Choices A, B, and D are incorrect because while they may be congenital defects in children, they are not commonly associated with Down syndrome. Hypospadias is a urogenital condition, pyloric stenosis affects the stomach, and hip dysplasia involves the hip joint, but these are not typically seen as frequently as heart defects in children with Down syndrome.
3. In a disaster area, a nurse assesses an adult male with partial-thickness burns on his lower legs, approximately 10% of his lower body. Which color of triage tag should the nurse place on this client?
- A. Yellow.
- B. Black.
- C. Red.
- D. Green.
Correct answer: A
Rationale: A yellow triage tag should be placed on the client with partial-thickness burns covering 10% of his lower body. Yellow tags indicate delayed treatment, suitable for serious injuries that are not immediately life-threatening. Black tags are used for deceased individuals, red tags for immediate treatment of life-threatening injuries, and green tags for minor injuries.
4. A female client who was involved in a motor vehicle collision is admitted with a fractured left femur which is immobilized using a fracture traction splint in preparation for an open reduction internal fixation (ORIF). The nurse determines that her distal pulses are diminished in the left foot. Which interventions should the nurse implement? (Select all that apply)
- A. Verify pedal pulses using a doppler pulse device.
- B. Monitor left leg for pain, pallor, paresthesia, paralysis, pressure.
- C. Evaluate the application of the splint to the left leg.
- D.
Correct answer: C
Rationale: It is crucial for the nurse to evaluate the application of the splint to the left leg in a client with diminished distal pulses. This assessment helps ensure that the splint is not causing any compromise to circulation. Verifying pulses and monitoring for leg conditions are important interventions but do not directly address the issue with the splint application in this scenario, making them less relevant.
5. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?
- A. Low oxygen levels are present in the blood.
- B. High levels of carbon dioxide have accumulated in the blood.
- C. Increased bicarbonate levels are causing alkalosis.
- D. Respiratory rate is increased, causing hyperventilation.
Correct answer: B
Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.
