Question 1 of 5
The LPN/LVN is aware of the drug cycle that begins with the administration of a drug. Which factor(s) would influence the amount of time needed to complete the drug cycle of a drug?
Correct Answer: A,C,D,E
Rationale: The correct answer is A, C, D, and E.
A: Age can affect drug metabolism and clearance rates, influencing the time needed for the drug cycle.
C: Whether the drug is a brand or generic drug can impact bioavailability and absorption rates, affecting the drug cycle duration.
D: The route of administration determines the drug's absorption rate and onset of action, which can affect the speed of the drug cycle.
E: The overall health of the patient's organs can impact drug metabolism and excretion, influencing the duration of the drug cycle.
Therefore, these factors can collectively influence the amount of time needed to complete the drug cycle of a drug.
Question 2 of 5
The LPN/LVN is assisting in the care of a patient with metastatic cancer. The patient expresses feelings of hopelessness and frustration over the unavailability of effective medical therapy in the United States. Which information would the LPN/LVN provide to the patient regarding approval of drugs in the United states?
Correct Answer: D
Rationale: The correct answer is D: The FDA requires drugs to be scientifically researched and this can take up to 8 years. The LPN/LVN would provide this information to the patient to explain the process of drug approval in the United States. The FDA ensures that drugs are safe and effective through rigorous scientific research and clinical trials. This process can indeed take several years to complete.
A: While clinical trials are an option, it is not the primary focus of the FDA approval process.
B: Traveling to another country for medication may not be safe or legal.
C: Herbal remedies are not regulated or approved by the FDA for treating cancer.
In summary, choice D is correct as it explains the regulatory process for drug approval in the United States, while the other choices are either not related to FDA approval or may not be safe or effective options for the patient.
Question 3 of 5
A patient is scheduled for diagnostic testing. Which medication should the nurse anticipate that the health-care provider would order?
Correct Answer: A
Rationale:
Correct
Answer: A: Barium sulfate
Rationale: Barium sulfate is commonly used as a contrast agent for diagnostic imaging studies like barium swallow or barium enema to visualize the gastrointestinal tract. It helps highlight specific structures and detect abnormalities. The health-care provider would likely order this medication for the patient to enhance the accuracy of the diagnostic testing.
Summary of Other
Choices:
B: Penicillin (PCN) - Penicillin is an antibiotic used to treat bacterial infections, not for diagnostic testing purposes.
C: Estrogen - Estrogen is a hormone replacement therapy used for various medical conditions, not typically ordered for diagnostic testing.
D: Naloxone - Naloxone is a medication used as an antidote for opioid overdose, not relevant for diagnostic testing in this scenario.
Question 4 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 5 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.
