1. A client with Graves' disease is being educated by a nurse about her prescribed medications. Which of the following statements by the client indicates an understanding of the use of Propranolol in the treatment of Graves' disease?
- A. Propranolol helps increase blood flow to my thyroid gland.
- B. Propranolol is used to prevent excess glucose in my blood.
- C. Propranolol will decrease my tremors and fast heartbeat.
- D. Propranolol promotes a decrease of thyroid hormone in my body.
Correct answer: C
Rationale: The correct answer is C. Propranolol is a beta-adrenergic antagonist that is commonly used in Graves' disease to decrease symptoms such as tremors and fast heart rate. Choice A is incorrect because Propranolol does not increase blood flow to the thyroid gland. Choice B is incorrect as Propranolol is not used to prevent excess glucose in the blood. Choice D is also incorrect as Propranolol does not directly decrease thyroid hormone levels in the body.
2. Which of the following conditions is not treated with Methotrexate?
- A. Sarcomas
- B. Leukemias
- C. Ectopic pregnancy
- D. Rheumatic fever
Correct answer: D
Rationale: The correct answer is D. Methotrexate is not typically used to treat rheumatic fever, which is more commonly managed with antibiotics to eradicate the underlying infection. Methotrexate is commonly used in the treatment of conditions like sarcomas, leukemias, and ectopic pregnancies due to its anti-inflammatory and anti-cancer properties.
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 is the antidote for Warfarin?
- A. Vitamin D
- B. Vitamin C
- C. Vitamin K
- D. Vitamin B6
Correct answer: C
Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.
5. A client received IV Verapamil to treat supraventricular tachycardia (SVT). The client's pulse rate is now 98/min, and blood pressure is 74/44 mm Hg. The nurse should anticipate a prescription for which of the following IV medications?
- A. Calcium gluconate
- B. Sodium bicarbonate
- C. Potassium chloride
- D. Magnesium sulfate
Correct answer: A
Rationale: In this situation, where the client's blood pressure is significantly lowered due to Verapamil administration, the nurse should anticipate a prescription for Calcium gluconate. Calcium gluconate is used to reverse severe hypotension caused by Verapamil. It should be given slowly intravenously as it counteracts the vasodilation caused by Verapamil, helping to normalize blood pressure levels. Sodium bicarbonate is not indicated for low blood pressure. Potassium chloride and magnesium sulfate are not the appropriate choices to address hypotension caused by Verapamil.
