1. Phenytoin is an antiarrhythmic and anticonvulsant that has an unlabeled use for:
- A. Headaches
- B. Cold remedy
- C. Neuropathic pain
- D. Antianxiety
Correct answer: C
Rationale: Phenytoin, an antiarrhythmic and anticonvulsant medication, is also used off-label for treating neuropathic pain. While its primary indications are for managing heart rhythm disorders and seizures, it has shown efficacy in managing neuropathic pain, expanding its clinical utility. Choices A, B, and D are incorrect as phenytoin is not commonly used for headaches, cold remedies, or antianxiety purposes.
2. A client with chronic myeloid leukemia is receiving hydroxyurea. Which of the following findings should the nurse monitor?
- A. Hyperkalemia
- B. Hypertension
- C. Neutropenia
- D. Tinnitus
Correct answer: C
Rationale: The nurse should monitor the client for neutropenia when receiving hydroxyurea. Neutropenia is a common adverse effect caused by bone marrow suppression. It is essential to assess the client's white blood cell count regularly to detect neutropenia early and prevent complications such as infections.
3. A client has a new prescription for combination oral NRTIs for the treatment of HIV. Which of the following statements should the nurse include in discharge teaching?
- A. These medications work by inhibiting enzymes to prevent HIV replication.
- B. These medications work by preventing protein synthesis within the HIV cell.
- C. These medications work by weakening the cell wall of the HIV virus.
- D. These medications work by blocking HIV entry into cells.
Correct answer: A
Rationale: The correct answer is A. NRTI antiretroviral medications inhibit the enzyme reverse transcriptase, which is essential for HIV replication. By blocking this enzyme, the medications prevent the virus from replicating and spreading. This mechanism of action helps to control the progression of HIV infection in the body. Choices B, C, and D are incorrect because NRTIs do not work by preventing protein synthesis, weakening the cell wall of the virus, or blocking HIV entry into cells. These mechanisms are associated with different classes of antiretroviral medications used in HIV treatment.
4. What symptom would alert the healthcare professional to hold Albuterol and notify a healthcare professional immediately?
- A. Insomnia
- B. Paradoxical bronchospasm
- C. Nausea
- D. Headache
Correct answer: B
Rationale: If a patient experiences paradoxical bronchospasm after taking Albuterol, the medication should be withheld, and a healthcare professional should be notified immediately. Paradoxical bronchospasm is a serious adverse reaction where the airways constrict instead of dilating, leading to breathing difficulties. This condition requires prompt medical attention to assess and manage the patient's respiratory status. The other options, insomnia, nausea, and headache, are not typically associated with the need to hold Albuterol and notify a healthcare professional immediately.
5. Which of the following drugs is associated with extreme photosensitivity as a reaction?
- A. Digitalis
- B. Niacin
- C. Tetracycline
- D. Fluoroquinolones
Correct answer: C
Rationale: Tetracycline is known to cause extreme photosensitivity reactions, making individuals more sensitive to sunlight and increasing the risk of severe sunburn. It is essential for patients taking tetracycline to protect themselves from excessive sun exposure to prevent adverse reactions.
