1. Select all that apply. A person who is deficient in vitamin A could consume which of the following to increase vitamin A levels?
- A. cantaloupe
- B. eggs
- C. carrots
- D. all of the above
Correct answer: D
Rationale: Vitamin A can be found in high amounts in foods like cantaloupe, eggs, carrots, and milk, all of which help to maintain healthy vision, skin, and immune function.
2. 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.
3. Each statement is true of rickets, except one. Which is the exception?
- A. Rickets is being diagnosed more frequently in the United States.
- B. Rickets is caused by vitamin C deficiency.
- C. Tachetic deformities such as bow legs or knock-knees develop.
- D. A narrow and distorted chest occurs.
Correct answer: B
Rationale: Rickets is caused by vitamin D deficiency, not vitamin C deficiency. It usually occurs in children who are 1 to 3 years old. The name rickets came from the word 'wrikken,' meaning 'to bend or twist.' Common manifestations of rickets include tachetic deformities like bow legs or knock-knees, a narrow and distorted chest, and failure of the epiphyses of bones to develop normally, resulting in twisted and warped bones. While the diagnosis of rickets may be increasing in the United States, it is not caused by a lack of vitamin C.
4. Monosaccharides are converted into glucose in the liver to provide an energy supply to the cells.
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct answer: A
Rationale: Both statements are true. Monosaccharides are indeed converted into glucose in the liver. Glucose, in turn, serves as a primary energy source for cells in the body, providing the necessary fuel for various cellular functions. The liver plays a crucial role in regulating blood glucose levels by converting monosaccharides into glucose and releasing it into the bloodstream when needed. Therefore, option A is the correct choice. Options B, C, and D are incorrect because both statements are accurate in this context.
5. The principal cation in plasma and interstitial fluid is:
- A. Sodium
- B. Potassium
- C. Calcium
- D. Magnesium
Correct answer: A
Rationale: The principal cation in plasma and interstitial fluid is sodium. Sodium plays a crucial role in maintaining fluid balance and is the primary cation in extracellular fluids like plasma and interstitial fluid. Potassium is the primary cation within cells, not in extracellular fluids, making it an incorrect choice. Calcium and magnesium are essential minerals but are not the principal cations in plasma and interstitial fluid, so they are also incorrect choices.
