Question 1 of 5
The mother of a male child with cystic fibrosis tells the nurse that she hopes her son's children won't have the disease. The nurse is aware that:
Correct Answer: B
Rationale: Most males with cystic fibrosis are sterile due to congenital absence of the vas deferens, significantly reducing the likelihood of having biological children.
Question 2 of 5
A client is to receive 1,000 mL of potassium chloride in 5% dextrose injection (D5W) intravenously over 3 hours and 20 minutes using a drop factor of 15 drops/mL. What is the required flow rate (drops) per minute? Record your answer using a whole number.
Correct Answer: 75
Rationale:
To calculate the flow rate in drops per minute, use the formula: (
Total volume X Drop factor)/
Total time in minutes. The total volume is 1,000 mL, the drop factor is 15 drops/mL, and the time is 3 hours 20 minutes = 200 minutes. Thus, (1,000 X 15)/ 200 = 15,000/ 200 = 75 drops/minute.
Question 3 of 5
The client is admitted following repair of a fractured tibia and cast application. Which nursing assessment should be reported to the doctor?
Correct Answer: C
Rationale: Weak and rapid pedal pulses suggest compromised circulation, which requires immediate reporting to prevent complications like compartment syndrome.
Question 4 of 5
The nurse is performing discharge teaching to a client who is on isoniazid (INH). Which diet selection would let the nurse know that the teaching has been ineffective?
Correct Answer: A
Rationale: Isoniazid can interact with tyramine-rich foods like tuna, causing adverse effects (e.g., hypertension). Selecting tuna casserole indicates ineffective teaching. The other foods are safe.
Question 5 of 5
The client is diagnosed with multiple myloma. The doctor has ordered cyclophosphamide (Cytoxan). Which instruction should be given to the client?
Correct Answer: D
Rationale: Cyclophosphamide can cause hemorrhagic cystitis; adequate hydration (e.g., 8 glasses of water) helps prevent this.
