A form of cancer therapy wherein a beam of high-energy electromagnetic radiation desires the cancer ceils?
- A. surgery
- B. radiation therapy
- C. chemotherapy
- D. pallitive treatment Situation: The nurse is assigned in a counseling clinic about preventive measures for cancers.
Correct Answer: B
Rationale: Radiation therapy is a form of cancer treatment that uses a beam of high-energy electromagnetic radiation to target and destroy cancer cells. The high-energy radiation damages the DNA in cancer cells, causing them to die or be unable to multiply. By precisely targeting the tumor with these radiation beams, radiation therapy helps to minimize damage to surrounding healthy tissues. This form of therapy is an essential component in the treatment of many types of cancer, either alone or in combination with surgery, chemotherapy, or other treatments.

A client is receiving chemotherapy to treat breath cancer. Which assessment finding indicates a fluid and electrolyte imbalance induced by chemotherapy?
- A. A Urine output of 400 ml in 8 hours
- B. B. Serum potassium level of 3.6 mEq/L
- C. C. Blood pressure of 120/64 to 130/72 mm Hg
- D. D. Dry oral mucous membranes and cracked lips
Correct Answer: A
Rationale: Chemotherapy can cause fluid and electrolyte imbalances in the body, leading to potential kidney damage and altered urinary output. A low urine output of 400 ml in 8 hours could indicate dehydration or impaired renal function, both of which can be induced by chemotherapy. Monitoring urine output is crucial in assessing the patient's fluid balance and kidney function during chemotherapy. It is essential to identify and address such imbalances promptly to prevent complications.
After surgery the nurse notes that the patient's urine is dark amber and concentrated. Which of the following does the nurse understand may be the reason for this?
- A. The sympathetic nervous system saves fluid in response to stress of surgery.
- B. The sympathetic nervous system diereses fluid in response to stress of surgery.
- C. The parasympathetic nervous system saves fluid in response to stress of surgery.
- D. The parasympathetic nervous system diereses fluid in response to stress of surgery.
Correct Answer: A
Rationale: The sympathetic nervous system saves fluid in response to the stress of surgery, leading to the urine becoming dark amber and concentrated. During stressful events such as surgery, the body activates the sympathetic nervous system as part of the fight-or-flight response. One of the functions of the sympathetic nervous system in this situation is to conserve fluids in the body by reducing urine output. This results in more concentrated urine, often appearing dark amber in color. Conversely, the parasympathetic nervous system is not typically involved in conserving fluid during stress responses.
Mr. Reyea complains of hearing ringing noises. The nurse recognizes that this assessment suggests injury of the
- A. Frontal lobe
- B. Six cranial nerve (abducent)
- C. Occipital lobe
- D. Eight Cranial Nerve (Vestibulocochlear)
Correct Answer: D
Rationale: The eighth cranial nerve is the vestibulocochlear nerve, which is responsible for transmitting auditory and balance information from the inner ear to the brain. Complaints of hearing ringing noises, also known as tinnitus, suggest a dysfunction or injury to the vestibulocochlear nerve. Tinnitus is a common symptom of various inner ear disorders such as noise-induced hearing loss, Meniere's disease, or acoustic neuroma. Therefore, the nurse should investigate further for possible issues related to the vestibulocochlear nerve when a patient reports hearing ringing noises.
