1. A client is receiving IV Dopamine for the treatment of shock. Which of the following findings indicates that the medication is effective?
- A. Increased heart rate
- B. Decreased blood pressure
- C. Increased urine output
- D. Decreased respiratory rate
Correct answer: C
Rationale: Dopamine is a medication used in shock to increase cardiac output and improve renal perfusion. An increase in urine output indicates that the medication is effective as it shows improved renal perfusion and kidney function, which are essential for managing shock effectively. Choices A, B, and D are incorrect as an increased heart rate, decreased blood pressure, and decreased respiratory rate are not direct indicators of the effectiveness of IV Dopamine in treating shock.
2. A client has a prescription for Prednisone for the treatment of Rheumatoid Arthritis. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will increase my intake of potassium-rich foods.
- B. I should take my medication with food.
- C. I will decrease my intake of calcium-rich foods.
- D. I should avoid eating grapefruit while taking this medication.
Correct answer: A
Rationale: The correct answer is A. Prednisone can cause hypokalemia, leading to low potassium levels. Increasing the intake of potassium-rich foods helps prevent this imbalance. Choices B, C, and D are incorrect because taking Prednisone with food, decreasing calcium-rich foods, or avoiding grapefruit are not specifically related to addressing the side effect of hypokalemia associated with Prednisone.
3. A client has ordered a thrombolytic medication for the treatment of CVA. Which type of stroke should not be treated with a thrombolytic?
- A. Hemorrhagic stroke
- B. Thrombotic stroke
- C. Both types can be treated with a thrombolytic
- D. Neither type can be treated with a thrombolytic
Correct answer: A
Rationale: Thrombolytic medications are used to dissolve blood clots. In the case of a hemorrhagic stroke, where there is bleeding in the brain, the use of thrombolytics can worsen the condition by increasing bleeding. Therefore, hemorrhagic strokes should not be treated with thrombolytic medications.
4. What is levothyroxine's pharmacologic classification?
- A. Thyroid Preparations
- B. Metabolic Inhibitors
- C. Analgesic
- D. Loop Diuretic
Correct answer: A
Rationale: Levothyroxine is classified as a thyroid preparation because it is a synthetic form of the thyroid hormone thyroxine. It is primarily used to treat hypothyroidism by supplementing or replacing the natural thyroid hormones in the body, helping to regulate metabolism and energy levels. Choice B, Metabolic Inhibitors, is incorrect because levothyroxine does not inhibit metabolism but rather helps regulate it. Choice C, Analgesic, is incorrect as levothyroxine is not used for pain relief but for thyroid hormone replacement therapy. Choice D, Loop Diuretic, is also incorrect as loop diuretics are medications that act on the kidneys to increase urine production and are not related to thyroid hormone replacement therapy.
5. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
