At health fair, an oncology nurse answers questions about risk factors for various types of cancer. One person with a family history of colon cancer asks the nurse to identify risk factors for this type of cancer. The nurse should identify:
- A. Smoking
- B. Obesity
- C. Heavy alcohol consumption
- D. Saccharin consumption
Correct Answer: B
Rationale: The correct answer is B: Obesity. Obesity is a known risk factor for colon cancer as excess body fat, especially around the waist, can lead to inflammation and insulin resistance, increasing the likelihood of cancerous cell growth in the colon. Smoking (choice A) is more strongly associated with lung and other types of cancer, not specifically colon cancer. Heavy alcohol consumption (choice C) is linked to other types of cancer, such as liver and esophageal cancer, but not as strongly to colon cancer. Saccharin consumption (choice D) has not been definitively linked to an increased risk of colon cancer.

Which of the following intravenous solutions is hypotonic?
- A. Normal saline
- B. Ringer’s lactate
- C. 0.45% saline
- D. 5% dextrose in normal saline A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET F
Correct Answer: C
Rationale: The correct answer is C: 0.45% saline. This solution is hypotonic because it has a lower osmolarity compared to the intracellular fluid. It contains fewer solutes than the cells, causing water to move into the cells by osmosis, potentially causing them to swell.
Normal saline (A) and Ringer's lactate (B) are isotonic solutions, meaning they have a similar osmolarity to the intracellular fluid and do not cause significant water shifts.
5% dextrose in normal saline (D) is a hypertonic solution, containing more solutes than the cells, leading to water movement out of the cells.
What would be the most appropriate intervention for a patient with aphasia who state, "I want a ..." and then stops?
- A. Wait for the patient to complete the sentence.
- B. Immediately begin showing the patient various objects In the environment.
- C. Leave the room and come back later.
- D. Begin naming various objects that the patient could be referring to.
Correct Answer: A
Rationale: The correct answer is A: Wait for the patient to complete the sentence. This is the most appropriate intervention for a patient with aphasia because rushing the patient or providing suggestions can be counterproductive. Waiting allows the patient time to find the words they are looking for and encourages communication. It shows respect for the patient's autonomy and gives them the opportunity to express themselves fully. Choice B may overwhelm the patient, Choice C disrupts the communication process, and Choice D may not align with the patient's intended communication. Patience and support are key in aiding a patient with aphasia.
A nurse is conducting a health history interview for a woman at an assisted-living facility. The woman says, “I have been so constipated lately.” How should the nurse respond?
- A. “Do you have a family history of chest problems?”
- B. “Why don’t you use a laxative every night?”
- C. “Do you take anything to help your constipation?”
- D. “Everyone who ages has bowel problems.”
Correct Answer: C
Rationale: The correct answer is C. The nurse should respond by asking, “Do you take anything to help your constipation?” This response shows active listening and gathers more information about the woman’s current management of constipation. It allows the nurse to assess the woman's current treatment regimen and potential underlying causes.
Choice A is incorrect as it diverts the conversation to chest problems, which is unrelated to the woman's primary concern of constipation. Choice B is incorrect as it suggests a potentially harmful solution without assessing the woman's current treatment or determining the cause of her constipation. Choice D is incorrect as it generalizes bowel problems with aging without addressing the woman's specific issue or management.
The lungs regulate acid-base balance b₃y⁻ all of the following except:
- A. Excreting HCO into the blood
- B. Controlling carbon dioxide levels
- C. Slowing ventilation
- D. Increasing ventilation
Correct Answer: C
Rationale: The correct answer is C: Slowing ventilation. The lungs regulate acid-base balance by controlling carbon dioxide levels through ventilation. Increasing ventilation helps expel excess carbon dioxide, thus regulating pH. Slowing ventilation would lead to CO2 buildup and an imbalance in acid-base levels. Excreting HCO3- into the blood (choice A) helps maintain pH, while increasing ventilation (choice D) aids in removing excess CO2. Therefore, slowing ventilation is the exception as it would disrupt the acid-base balance by not effectively regulating carbon dioxide levels.
Several hours after returning from surgery, the nurse tells the patient that she is ordered to be ambulated. The patient asks, “Why?” Which of the following complications would the nurse correctly explain can be prevented by early postoperative ambulation?
- A. Increased peristalsis
- B. Coughing
- C. Pneumonia
- D. Wound healing A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET K
Correct Answer: C
Rationale: The correct answer is C: Pneumonia. Early postoperative ambulation helps prevent pneumonia by promoting lung expansion, increasing oxygenation, and preventing atelectasis. A: Increased peristalsis is unrelated to ambulation. B: Coughing is important for airway clearance but not directly related to ambulation. D: Wound healing is influenced by various factors, but ambulation primarily impacts respiratory function.
