1. _____ neutralizes stomach acid in the small intestine:
- A. saliva
- B. gastric mucus
- C. bicarbonate ions
- D. enzymes
Correct answer: C
Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.
2. Low levels of physical activity are more commonly associated with which type of cancer?
- A. Esophageal cancer
- B. Pancreatic cancer
- C. Lung cancer
- D. Colon cancer
Correct answer: D
Rationale: Low physical activity is most strongly associated with an increased risk of colon cancer. Regular exercise helps regulate bowel movements and reduce inflammation, which are factors that can contribute to the development of colon cancer. Esophageal cancer, pancreatic cancer, and lung cancer are not as directly linked to low levels of physical activity.
3. Toilet training occurs in the anal stage of Freud’s psychosexual development. This is equivalent to Erikson’s:
- A. Trust vs. Mistrust
- B. Autonomy vs. Shame and Doubt
- C. Initiative vs. Guilt
- D. Industry vs. Inferiority
Correct answer: A
Rationale: The correct answer is A: Trust vs. Mistrust. In Freud's psychosexual development theory, the anal stage is where toilet training occurs, focusing on issues of control and independence. This stage is parallel to Erikson's Trust vs. Mistrust stage, where infants learn to trust or mistrust their caregivers based on the consistency of care they receive. Choices B, C, and D are incorrect as they correspond to different stages in Erikson's psychosocial development theory, not related to toilet training or the anal stage of Freud's theory.
4. While on Bryant’s traction, which of these observations of Graciela and her traction apparatus would indicate a decrease in the effectiveness of her traction?
- A. Graciela’s buttocks are resting on the bed.
- B. The traction weights are hanging 10 inches above the floor.
- C. Graciela’s legs are suspended at a 90 degree angle to her trunk.
- D. The traction ropes move freely through the pulley.
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
5. What are the manifestations of nephrotic syndrome?
- A. Dehydration
- B. Uremia
- C. Infection
- D. Low blood lipids
Correct answer: C
Rationale: Infection is a common manifestation of nephrotic syndrome. This is due to the loss of immunoglobulins in the urine, which weakens the body's immune defenses. Dehydration (Choice A) and uremia (Choice B) can be symptoms of kidney dysfunction but are not specific manifestations of nephrotic syndrome. Low blood lipids (Choice D) is incorrect as nephrotic syndrome typically results in high, not low, blood lipid levels due to the body's attempt to replace lost proteins.
