Question 1 of 5
Vitamin C can be found in which of the following sources?
Correct Answer: B
Rationale: The correct answer is B: plants. Vitamin C, also known as ascorbic acid, is commonly found in fruits and vegetables, which are plant-based sources. Citrus fruits like oranges, strawberries, and vegetables like bell peppers and broccoli are rich in vitamin C. Plants produce vitamin C through their metabolism, making them a primary source of this essential nutrient in our diet. Choosing options A, C, or D is incorrect as minerals, animal sources, and solvents do not naturally contain vitamin C. Minerals are inorganic compounds, animal sources typically do not produce vitamin C, and solvents are chemicals used for dissolving substances. Hence, option B is the correct answer as it aligns with the natural sources of vitamin C.
Question 2 of 5
An oncology patient is admitted to the nursing unit under hospice care Which medication should the nurse anticipate that the health-care provider will order?
Correct Answer: D
Rationale: The correct answer is D: Palliative therapy. In hospice care for oncology patients, the focus is on providing comfort and symptom management rather than curative treatment. Palliative therapy aims to improve the quality of life by addressing pain, nausea, and other distressing symptoms. Prophylactic antibiotics (choice
A) are used to prevent infections, curative therapy (choice
B) is not appropriate in hospice care, and diagnostic medication (choice
C) is not necessary as the patient's diagnosis is already known.
Therefore, the most appropriate choice for an oncology patient in hospice care is palliative therapy.
Question 3 of 5
The nurse is taking care of a patient who has hypothyroid disease. What category medications would the nurse anticipate be ordered?
Correct Answer: A
Rationale: The correct answer is A: replacement. In hypothyroid disease, the thyroid gland does not produce enough thyroid hormone, so replacement medications like levothyroxine are needed to supplement the hormone. This helps restore normal thyroid hormone levels in the body.
Choices B, C, and D are incorrect because hypothyroidism is a chronic condition that requires ongoing treatment rather than a curative, prophylactic, or palliative approach.
Question 4 of 5
While caring for a patient scheduled for knee replacement surgery, the nurse provides cefazolin(antibiotic) as ordered 30 minutes preoperatively. Which statement indicates that teaching has been effective?
Correct Answer: D
Rationale: The correct answer is D. This antibiotic is given as a prophylactic to help reduce the risk of infection after surgery. The rationale is that cefazolin is commonly used as a prophylactic antibiotic before surgery to prevent postoperative infections. By administering it 30 minutes before knee replacement surgery, the nurse is following best practices to reduce the risk of surgical site infections.
Choice A is incorrect because cefazolin is not indicated for replacing vitamins and minerals lost during surgery.
Choice B is incorrect as cefazolin is not a pain medication but an antibiotic.
Choice C is incorrect because cefazolin does not help the surgeon identify areas of bone destruction.
In summary, the correct answer (
D) is supported by the fact that administering cefazolin preoperatively is a standard practice to reduce the risk of infection, while the other choices are incorrect because they do not align with the purpose and mechanism of action of cefazolin.
Question 5 of 5
While caring for a patient with a history of hypothyroidism, the nurse expects which of the following medications to be included in the patient's medication list?
Correct Answer: B
Rationale: The correct answer is B: replacement. In hypothyroidism, the thyroid gland does not produce enough thyroid hormone. Replacement therapy with synthetic thyroid hormone (levothyroxine) is essential to restore hormone levels to normal. This medication helps alleviate symptoms and prevent complications associated with hypothyroidism.
A: Prophylactic medications are used to prevent disease, not to treat hypothyroidism.
C: Palliative medications aim to relieve symptoms but do not address the underlying cause like replacement therapy does for hypothyroidism.
D: Curative medications aim to cure the disease, which is not typically possible in hypothyroidism.
Therefore, the most appropriate medication for a patient with hypothyroidism is replacement therapy.
