ATI Proctored Pharmacology Test
1. A client asks the nurse how Rituximab works, which the client is receiving to treat Non-Hodgkin's Leukemia. Which of the following should the nurse include?
- A. Blocks hormone receptors
- B. Increases immune response
- C. Binds with specific antigens on tumor cells
- D. Stops DNA replication during cell division
Correct answer: C
Rationale: Rituximab is a monoclonal antibody that binds with specific antigens on B-lymphocytes, leading to the destruction of cancer cells. In the context of Non-Hodgkin's Leukemia, Rituximab targets and destroys cancerous B-lymphocytes, which helps in treating the disease. Choices A, B, and D are incorrect. Rituximab does not block hormone receptors, increase immune response, or stop DNA replication during cell division. The primary mode of action of Rituximab is its binding with specific antigens on tumor cells, specifically B-lymphocytes, to elicit an immune response against cancerous cells.
2. A client has a new prescription for Raltegravir. Which of the following statements should the nurse include in teaching the client?
- A. This medication prevents the virus from entering the cell.
- B. This medication prevents the virus from leaving the cell.
- C. This medication blocks the virus from attaching to the cell.
- D. This medication blocks the virus from replicating in the cell.
Correct answer: D
Rationale: The correct answer is D because Raltegravir works by blocking the integrase enzyme, preventing the virus from integrating its genetic material into the host cell's DNA. By inhibiting this process, viral replication within the host cell is halted. Choices A, B, and C are incorrect because Raltegravir's mechanism of action specifically targets viral replication within the cell, not virus entry, exit, or attachment to the cell.
3. A client has a new prescription for Labetalol. Which of the following instructions should be included?
- A. Take this medication at bedtime.
- B. Avoid sudden discontinuation of the medication.
- C. Increase your intake of sodium-rich foods.
- D. Avoid drinking grapefruit juice.
Correct answer: B
Rationale: The correct answer is to instruct the client to avoid sudden discontinuation of Labetalol. Abrupt discontinuation of beta-blockers like Labetalol can lead to rebound hypertension and other cardiac issues. It is important for clients to taper off the medication under healthcare provider guidance to prevent potential complications.
4. When starting therapy with doxorubicin, which of the following findings should the nurse instruct the client to report?
- A. Hair loss
- B. Fatigue
- C. Sore throat
- D. Red urine
Correct answer: C
Rationale: The nurse should instruct the client to report a sore throat because it can indicate an infection due to the immunosuppressive effects of doxorubicin. Doxorubicin is known to suppress the immune system, making patients more susceptible to infections. Monitoring and reporting early signs of infection, such as a sore throat, are essential to prevent complications. Hair loss and fatigue are common side effects of doxorubicin but do not typically indicate immediate concerns for infection. Red urine is a known side effect of doxorubicin but is not a priority over potentially serious infections that can arise.
5. A healthcare professional is admitting a toddler to the hospital after an Acetaminophen overdose. Which of the following medications should the healthcare professional anticipate administering to this client?
- A. Acetylcysteine
- B. Pegfilgrastim
- C. Misoprostol
- D. Naltrexone
Correct answer: A
Rationale: The correct answer is Acetylcysteine. Acetylcysteine is the antidote for acetaminophen overdose. It works by replenishing glutathione, which is depleted in cases of acetaminophen overdose, thus preventing liver damage. Pegfilgrastim is a medication used to stimulate white blood cell production, misoprostol is a medication used to prevent gastric ulcers, and naltrexone is used in the management of opioid addiction and alcohol dependence, which are not indicated in the scenario described.
