What procedure examines a portion of the large intestine with an endoscope?
- A. Colposcopy
- B. Sigmoidoscopy
- C. Upper GI
- D. Cardiac catheterization
Correct Answer: B
Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.

Which of the following medical terms means 'surgical fixation of the stomach'?
- A. Abdominorrhaphy
- B. Gastroplasty
- C. Gastropexy
- D. Abdominorrhexis
Correct Answer: C
Rationale: The correct answer is 'Gastropexy,' which means 'surgical fixation of the stomach.' This procedure involves surgically fixing the stomach in place. 'Abdominorrhaphy' refers to suturing or repairing the abdomen, not related to fixing the stomach. 'Gastroplasty' is a surgical reconstruction of the abdomen, not specifically related to fixing the stomach. 'Abdominorrhexis' refers to the rupture or tearing of the abdomen, not a surgical fixation procedure.
Mr. Thomas is a well-groomed 68-year-old male patient who had prostate surgery two days ago. He has an indwelling catheter and a urinary drainage bag. You have weighed him at 9 am each morning for 3 mornings in a row. Today, on the 4th day, his morning weight is 3 pounds more than it was the day before. Why could he have gained these 3 pounds in one day, on a 1000 calorie diet?
- A. It is obvious that his visitors have been sneaking him junk food from the local fast-food restaurant.
- B. It may be that his urinary drainage bag was not emptied today and it was emptied on previous days.
- C. It is obvious that the scale is broken and it should be replaced immediately to prevent these false weights.
- D. A 3-pound weight gain is not significant enough to question and should just be noted.
Correct Answer: B
Rationale: The correct answer is that the weight gain may be due to the urinary drainage bag not being emptied today, while it was emptied on previous days. This scenario is common and can lead to an increase in weight that is not related to food intake. Choice A is incorrect because assuming visitors are sneaking junk food is speculative and not based on facts. Choice C is incorrect as there is no evidence to suggest the scale is broken. Choice D is incorrect because any unexplained weight gain should be investigated further, even if it seems insignificant at first.
While explaining an illness to a 10-year-old, what should the nurse keep in mind about the cognitive development at this age?
- A. They are able to make simple associations of ideas
- B. They are able to think logically in organizing facts
- C. Interpretation of events originates from their own perspective
- D. Conclusions are based on previous experiences
Correct Answer: B
Rationale: At the age of 10, children are in the concrete operations stage according to Piaget. They are capable of mature thought when allowed to manipulate and organize objects. This means they can think logically, organize facts, and understand cause-and-effect relationships. Choices A, C, and D are incorrect. While simple associations of ideas may occur, the key cognitive ability at this stage is the capacity for logical thought and organization of information. Interpretation of events from their own perspective is more characteristic of younger children, and conclusions based on previous experiences are more aligned with older children or adults.
Assuming that an elderly patient will have a difficult time understanding the directions for how to take medication is an example of:
- A. Prejudice
- B. Stereotyping
- C. Encoding
- D. Rationalization
Correct Answer: B
Rationale: Stereotyping is defined as providing a generalization about a person based on their culture or characteristics. In this scenario, assuming that an elderly patient will have difficulty understanding medication directions solely based on their age is an act of stereotyping. The healthcare provider is attributing a generalized trait to the patient without considering individual differences. Prejudice, on the other hand, involves forming a negative opinion about someone based on their heritage or culture, which is not evident in this situation. Encoding refers to the process of converting information into a form that can be stored in memory, and rationalization involves justifying one's behavior or decisions with logical reasons, neither of which are applicable in this context.
The body system that functions to maintain fluid balance, support immunity, and contains the spleen is the:
- A. Lymphatic System
- B. Digestive System
- C. Urinary System
- D. Respiratory System
Correct Answer: A
Rationale: The Lymphatic System is responsible for maintaining fluid balance and supporting immunity. It contains organs like the spleen, tonsils, thymus, lymph nodes, and lymph vessels. The spleen, a part of the lymphatic system, plays a crucial role in filtering blood and storing blood cells. The Digestive System is primarily involved in the breakdown and absorption of nutrients, not fluid balance or immunity. The Urinary System is responsible for filtering waste products from the blood and regulating fluid balance, but it does not support immunity or contain the spleen. The Respiratory System is focused on gas exchange and oxygenating the blood, not fluid balance or immunity.
