1. Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:
- A. it is chemically stable, nonallergenic, and can be administered orally once a day.
- B. it is available in a wide range of concentrations to meet individual client requirements.
- C. it is a prodrug of T3.
- D. it has a long half-life.
Correct answer: A
Rationale: Levothyroxine (Synthroid) is the preferred medication for hypothyroidism due to its chemical stability, nonallergenic properties, and convenient once-daily oral administration. It is safe and effective with minimal side effects when appropriately dosed. Choice B is incorrect because while Levothyroxine is available in various concentrations, it is not the reason it is the drug of choice; the primary reason is its stability and nonallergenic nature. Choice C is wrong as Levothyroxine (T4) is not a prodrug of T3; it is converted to T3 in the body. Option D is inaccurate because Levothyroxine has a long half-life (around 7 days), enabling once-daily dosing, as opposed to a short half-life.
2. The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:
- A. Manage peripheral edema
- B. Improve right ventricular function
- C. Increase pulmonary pressure
- D. Constrict the pulmonary vessels
Correct answer: B
Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension. Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action. Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation. Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.
3. What is the number one reason a person with alcohol addiction does not seek treatment?
- A. Co-dependency
- B. Denial
- C. Depression
- D. Stigma
Correct answer: B
Rationale: The correct answer is B: Denial. Individuals with alcohol addiction often deny that they have a drinking problem and may become defensive when confronted about it. This sense of denial can be a significant barrier to seeking treatment. Co-dependency, referred to in choice A, is a relationship dynamic and is not the primary reason for avoiding treatment. Depression, as mentioned in choice C, is a common co-occurring condition with alcohol addiction but is not typically the main factor preventing treatment-seeking. Stigma, as in choice D, can act as a deterrent, but denial of the problem itself is usually the primary obstacle to seeking help.
4. A client is admitted to telemetry with a diagnosis of diabetes at 3pm. At 10pm, the client is unresponsive. BP is 98/64, Resp 38, HR 100, T 97. The nurse notes a fruity smell on the client's breath. The nurse recognizes that the client is in which acid-base imbalance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: C
Rationale: Based on the client's unresponsiveness, fruity breath smell, and the presence of diabetes, the nurse can infer that the client is experiencing diabetic ketoacidosis (DKA). DKA is a complication of diabetes characterized by the accumulation of ketones in the body, leading to metabolic acidosis. The fruity breath smell is due to the presence of ketones. Therefore, the correct acid-base imbalance in this scenario is metabolic acidosis. Choice A, respiratory acidosis, is incorrect because the scenario does not provide evidence of primary respiratory dysfunction. Choice B, respiratory alkalosis, is incorrect as the client's condition does not align with the typical causes and symptoms of respiratory alkalosis. Choice D, metabolic alkalosis, is incorrect as the symptoms and history provided do not suggest a state of metabolic alkalosis.
5. On morning rounds, the nurse finds a somnolent client with a Blood glucose of 89 mg/dL. A sulfonurea and a proton pump inhibitor are scheduled to be administered. What is the nurse's best action?
- A. Give the proton pump inhibitor and hold the sulfonurea until the client eats
- B. Hold medications and notify the physician
- C. Arouse the client and give some orange juice with sugar packets added
- D. Give the medications as ordered and re-check blood sugar in one hour
Correct answer: A
Rationale: The correct action is to give the proton pump inhibitor and hold the sulfonurea until the client eats. Sulfonureas should be held for blood glucose levels below 100 mg/dL until the client has food to prevent hypoglycemia. Giving the proton pump inhibitor is appropriate and does not need to be delayed. Option B is incorrect because holding both medications without taking appropriate action may lead to further complications. Option C is not the best choice as it does not address the need to hold the sulfonurea until the client eats. Option D is incorrect because administering the medications without ensuring the client eats may lead to hypoglycemia.
