The nurse is caring for a patient with colon cancer who is scheduled for external radiation therapy to the abdomen. Which information obtained by the nurse would indicate a need for patient teaching?
- A. The patient has a history of dental caries.
- B. The patient swims several days each week.
- C. The patient snacks frequently during the day.
- D. The patient showers each day with mild soap.
Correct Answer: B
Rationale: Abdominal radiation fries skin swimming in chlorinated or salt water during treatment risks irritation or infection in that tender zone. Dental caries don't tie in. Snacking might help nutrition, not hurt. Mild soap showers are fine. Nurses in oncology flag this no swimming' protects radiated skin, a teaching must to dodge complications.
How many times more likely is a patient with diabetes to die from a cardiovascular condition compared with a patient without diabetes?
- A. 2-4x
- B. 8-10x
- C. 20-25x
- D. 40-50x

An intra-venous drug user with endocarditis has a TOE and multiple blood cultures taken. He is most likely to have:
- A. tricuspid valve involvement and s.aureus on blood culture
- B. tricuspid valve involvement and enterococci on blood culture
- C. mitral valve involvement and mixed growth on blood culture
- D. tricuspid valve involvement and candida on blood culture
Correct Answer: A
Rationale: IVDU endocarditis tricuspid flops, Staph aureus spikes, not enterococci, mixed, candida, or blanks. Nurses hear this chronic junkie beat.
The nurse receives an order to infuse heparin 1200 units/hr IV. The IV bag contains 25,000 units heparin in 500 mL D5W. Calculate the IV rate in mL/hr.
- A. 20
- B. 24
- C. 28
- D. 30
Correct Answer: B
Rationale: Heparin's drip: 1200 units/hr from 25,000 units in 500 mL 500 ÷ 25,000 = 0.02 mL/unit, times 1200 = 24 mL/hr, a nurse's calc to thin blood right. Off numbers (20, 28, 30) skew dosing. Precision keeps clots at bay, a steady flow in this IV dance.
A nurse provides care on a bone marrow transplant unit and is preparing a female patient for a hematopoietic stem cell transplantation (HSCT) the following day. What information should the nurse emphasize to the patient's family and friends?
- A. Your family should likely gather at the bedside in case there's a negative outcome
- B. Make sure she doesn't eat any food in the 24 hours before the procedure
- C. Wear a hospital gown when you go into the patient's room
- D. Do not visit if you've had a recent infection
Correct Answer: D
Rationale: HSCT wipes out immunity, leaving patients prone to sepsis recent infections in visitors could bring pathogens (e.g., flu, strep) into her sterile bubble. Telling family to skip visits if sick is priority, trumping gown-wearing (useful but secondary) or fasting (not typically 24 hours). Gathering for a bad outcome's overly grim HSCT's risky but not a death sentence pre-procedure. Nurses stress this to shield the patient during the 2-4 week engraftment window, when neutropenia peaks, making infection control the linchpin of pre-transplant education in oncology.
