1. 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.
2. A client has a prescription for ceftriaxone. Which of the following information should the nurse include in the teaching?
- A. You may develop a cough while taking this medication.
- B. You should stop taking this medication if you develop a rash.
- C. This medication cannot be given orally.
- D. This medication may cause your urine to turn yellow.
Correct answer: B
Rationale: The correct answer is B. A rash can indicate an allergic reaction to ceftriaxone, which should be reported to the provider. It is crucial to instruct the client to discontinue the medication and seek medical attention if a rash develops to prevent potential serious adverse effects. Choices A, C, and D are incorrect because cough is not a common side effect of ceftriaxone, ceftriaxone is typically administered parenterally, and a yellow discoloration of urine is a harmless side effect due to the color of the medication itself, respectively.
3. A healthcare provider is caring for a client who has a new prescription for Digoxin. Which of the following findings should the healthcare provider identify as a potential sign of Digoxin toxicity?
- A. Nausea
- B. Dry mouth
- C. Hypoglycemia
- D. Tinnitus
Correct answer: A
Rationale: Nausea is a potential sign of Digoxin toxicity. Along with vomiting, visual disturbances, and confusion, it can be an early indication of an overdose. Dry mouth is not typically associated with Digoxin toxicity. Hypoglycemia is a low blood sugar level and is not directly related to Digoxin toxicity. Tinnitus, a ringing in the ears, is not a common sign of Digoxin toxicity. Healthcare providers should closely monitor clients on Digoxin for symptoms like nausea to prevent serious complications.
4. 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.
5. A client has a new prescription for Labetalol. Which of the following instructions should the nurse include?
- 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 instruction for a client on Labetalol is to avoid sudden discontinuation of the medication. Labetalol is a beta-blocker that, if abruptly stopped, can lead to rebound hypertension and other cardiac issues. It is essential for patients to taper off this medication under medical supervision to prevent adverse effects.
