When reviewing the client’s medical record, the experienced nurse discovers that the client’s breast cancer is staged as T4 N3 M1. Which comment made by the experienced nurse to the new nurse is correct?
- A. “This client has a 3-cm breast tumor that has spread to only one lymph node.”
- B. “The TNM system is used to classify solid tumors by size and degree of spread.”
- C. “The higher the number in the TNM system, the better the chances are for a cure.”
- D. “This TNM system helps to classify tumors as either well- or poorly differentiated.”
Correct Answer: B
Rationale: A. The T4 N3 M1 indicates that the client’s primary tumor is very large, involves 3 lymph nodes, with distant metastasis (T is the size and extent and ranges from 1-4; N is number of nodes involved, and M1 indicates metastasis). B. This statement is correct. The tumor-node-metastasis (TNM) system classifies solid tumors by size and degree of spread. It is an international system that allows comparison of statistics among cancer centers. C. A higher number means that a more serious situation exists. D. A different rating system is used to define the cell types of tumors as well differentiated (closely resembles normal tissue) or poorly differentiated (tumor that contains some normal cells, but most cells are abnormal).

Which statement is the scientific rationale for infusing a unit of blood in less than four (4) hours?
- A. The blood will coagulate if left out of the refrigerator for greater than four (4) hours.
- B. The blood has the potential for bacterial growth if allowed to infuse longer.
- C. The blood components begin to break down after four (4) hours.
- D. The blood will not be affected; this is a laboratory procedure.
Correct Answer: B
Rationale: Blood must infuse within 4 hours (B) to minimize bacterial growth risk. Coagulation (A) is not primary, components (C) degrade minimally, and lab procedure (D) is incorrect.
The nurse is discussing dietary sources of iron with a client who has iron deficiency anemia. Which menu, if selected by the client, indicates the best understanding of the diet?
- A. Milkshake, hot dog, and beets
- B. Beef steak, spinach, and grape juice
- C. Chicken salad, green peas, and coffee
- D. Macaroni and cheese, coleslaw, and lemonade

The nurse is preparing to administer the chemotherapeutic agent cisplatin IV to the client with ovarian cancer. The dose is 100 mg/m2 in 2 liters of DSW to be infused over 8 hours. What is the rate in milliliters (mL) per hour that the nurse should set the infusion pump to deliver the medication? __________ mL/hour (Record your answer as a whole number.)
Correct Answer: 250
Rationale: first convert liters to milliliters: 1000 mL/1L= XmL/2L. 1000mL* 2L= 1L * x mL;
2000 mL = X. Next ,CALCULATE the mL per hour 2000 mL /8 Hours =250mL/hour
Which sign/symptom should the nurse expect to assess in the client diagnosed with hemophilia A?
- A. Epistaxis.
- B. Petechiae.
- C. Subcutaneous emphysema.
- D. Intermittent claudication.
Correct Answer: A
Rationale: Hemophilia A causes bleeding; epistaxis (A) is common. Petechiae (B) indicate thrombocytopenia, emphysema (C) is unrelated, and claudication (D) is vascular.
The nurse assesses that the client who is receiving radiation for cervical cancer continues to have diarrhea. Which nursing advice is most appropriate for this client?
- A. Eat a low-residue diet and take sitz baths twice daily.
- B. Drink fluids low in potassium and take frequent tub baths.
- C. Consume more milk products and take frequent showers.
- D. Drink high-sodium fluids and apply hydrocolloid pads to rectum.
Correct Answer: A
Rationale: A. The client with diarrhea should eat a low-residue diet to decrease roughage and bowel irritability and take sitz (or tub) baths twice daily to increase comfort. B. Intake of fluids that are high in potassium (not low) is recommended to replace electrolytes lost through diarrhea. C. Milk products are discouraged because they increase bowel irritability. D. Intake of fluids high in sodium should be avoided because it contributes to water retention, but hydrocolloid pads may be used on reddened areas to promote healing.
