Nursing Elites

1. Larry, 55 years old, who is suspected of having colorectal cancer, is admitted to the CI. After taking the history and vital signs the physician does which test as a screening test for colorectal cancer.

• A. Barium enema
• B. Carcinoembryonic antigen
• C. Annual digital rectal examination
• D. Proctosigmoidoscopy

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.

2. What does oliguria lead to in patients with acute kidney injury?

• A. Hypophosphatemia and overgrowth of bone tissue
• B. An increase in blood potassium levels due to excessive excretion of parathyroid hormone
• C. Sodium retention and elevated levels of potassium
• D. Edema due to increased urine production

Correct answer: C

Rationale: In patients with acute kidney injury, oliguria (reduced urine output) often results in sodium retention and hyperkalemia (elevated levels of potassium). This is due to the kidneys' decreased capacity to excrete these substances. Choice A is incorrect because hypophosphatemia and overgrowth of bone tissue are not direct consequences of oliguria in acute kidney injury. Choice B is incorrect because an increase in blood potassium levels is not caused by excessive excretion of parathyroid hormone but rather by decreased excretion of potassium. Choice D is incorrect because edema is not caused by increased urine production but rather by fluid overload due to decreased urine output.

3. A client was rushed in the E.R showing a whitish, leathery and painless burned area on his skin. The nurse is correct in classifying this burn as:

• A. First degree burn C. Third degree burn
• B. Second degree burn D. Partial thickness burn
• C.
• D.

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. What is the best snack choice for a preschool-age child?

• A. Fruit snacks
• B. Mini wheat bagel with peanut butter
• C. White toast with jelly
• D. Sports drink

Correct answer: B

Rationale: The best snack choice for a preschool-age child is a mini wheat bagel with peanut butter as it provides a good balance of carbohydrates, protein, and healthy fats. Fruit snacks, although they contain some fruit flavor, are often high in added sugars and lack essential nutrients. White toast with jelly may provide quick energy but lacks protein and healthy fats, which are important for a balanced snack choice. Sports drinks are typically high in sugar and unnecessary for a preschool-age child's snack, as they are designed for rehydration during intense physical activity, not as a regular snack option.

5. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.
