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: The correct answer is B: radiation therapy. Radiation therapy uses high-energy radiation to target and destroy cancer cells while minimizing damage to surrounding healthy tissues. It is a localized treatment that is effective in shrinking tumors and preventing cancer cell growth. Surgery (A) involves physically removing the tumor and surrounding tissues, while chemotherapy (C) uses drugs to kill cancer cells throughout the body. Palliative treatment (D) focuses on symptom management and improving quality of life in advanced stages of cancer. In this case, the focus is on a form of cancer therapy involving high-energy electromagnetic radiation, making radiation therapy the most appropriate choice.

The normal life expectancy for 50% of patients ith amyotropic lateral sclerosis (ALS) is:
- A. 3 years
- B. 10 years
- C. 5 years
- D. 20 years
Correct Answer: C
Rationale: The correct answer is C (5 years) because ALS is a progressive and fatal neurodegenerative disease. The median life expectancy for most ALS patients is around 3-5 years from the onset of symptoms. Choice A (3 years) is too short for 50% of patients. Choice B (10 years) and Choice D (20 years) are longer than the typical life expectancy for ALS patients, making them incorrect. The progression of ALS varies among individuals, but statistically, 50% of patients would be expected to live around 5 years after diagnosis.
A nurse completes a thorough database and carries out nursing interventions based on priority diagnoses. Which action will the nurse take next?
- A. Assessment
- B. Planning
- C. Implementation
- D. Evaluation
Correct Answer: D
Rationale: The correct answer is D: Evaluation. After implementing nursing interventions based on priority diagnoses, the nurse must evaluate the effectiveness of these interventions to determine if the desired outcomes have been achieved. Evaluation is crucial to assess the progress, make necessary modifications, and ensure the effectiveness of the care provided. Assessment (A) is already completed before interventions are carried out. Planning (B) involves developing a care plan based on assessment findings. Implementation (C) is the actual carrying out of the interventions. Therefore, the next step after implementing nursing interventions is to evaluate their effectiveness.
Which of the following responses indicates sympathetic nervous system function?
- A. Tachycardia, dilated pupils
- B. Hypoglycaemia, headache
- C. Increased peristalsis, abdominal cramping
- D. Pupil constriction, bronchoconstriction
Correct Answer: A
Rationale: The correct answer is A because tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation. Sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate and dilated pupils to prepare the body for quick action.
Choice B is incorrect because hypoglycemia and headache are not specific to sympathetic nervous system function. Choice C is incorrect because increased peristalsis and abdominal cramping are more indicative of parasympathetic nervous system activity. Choice D is incorrect because pupil constriction and bronchoconstriction are actions of the parasympathetic nervous system, responsible for rest and digest functions.
Which food is recommended for the patient who must increase intake of potassium?
- A. Bread
- B. Potato
- C. Egg
- D. Cereal
Correct Answer: B
Rationale: The correct answer is B: Potato. Potatoes are high in potassium, which is essential for various bodily functions. Potatoes can help increase potassium intake in patients who require it. Bread, eggs, and cereal are not as rich in potassium as potatoes. Increasing intake of these foods won't provide the necessary boost in potassium levels needed for the patient.
A 17-year-old boy is admitted in sickle cell crisis. Which of the ff. events most likely contributed to the onset of the crisis?
- A. He started a new job last week.
- B. He had seafood for dinner last night.
- C. He walked home in a cold rain
- D. He has not exercised for a week. yesterday.
Correct Answer: C
Rationale: The correct answer is C: He walked home in a cold rain. Walking in cold rain can lead to vasoconstriction, which impairs blood flow, increasing the likelihood of a sickle cell crisis in individuals with sickle cell disease. This can cause red blood cells to sickle and block blood vessels, leading to pain and tissue damage. Choices A, B, and D do not directly affect the physiology of sickle cell disease and are less likely to trigger a crisis.
