1. A client with a history of atrial fibrillation is prescribed digoxin. The nurse should monitor for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Headache
- D. Hyperglycemia
Correct answer: A
Rationale: The correct answer is A: Bradycardia. Digoxin can lead to bradycardia due to its effect on slowing down the heart rate, which can be dangerous in a client with atrial fibrillation. Monitoring the client's heart rate is essential to detect and manage this potential side effect. Choices B, C, and D are incorrect because digoxin is not known to cause tachycardia, headache, or hyperglycemia as common side effects.
2. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?
- A. Midway through administration of the IV dose and 30 minutes before the next
- B. Two hours after completion of the IV dose and 30 minutes before the next
- C. Two hours after completion of the IV dose and one hour before the next
- D. Immediately after completion of the IV dose and 30 minutes before
Correct answer: B
Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.
3. Escitalopram is prescribed for a 16-year-old adolescent client who is clinically depressed. Five days later, the parent tells the practical nurse (PN) that the drug is not working because their child is not feeling any better. Which explanation should the PN provide?
- A. It takes 1 to 4 weeks for antidepressant medications to become effective.
- B. The dosage may need to be increased; I will contact your health care provider.
- C. Depression is difficult to treat with drugs alone. Therapy sessions would enhance their effectiveness.
- D. Based on your child's response to this drug, the health care provider is reviewing your medication regimen.
Correct answer: A
Rationale: Antidepressant medications typically require 1 to 4 weeks to reach their full therapeutic effect. It is crucial to educate the family that during the initial week of treatment, the child may experience heightened anxiety. Therefore, it is important to wait for the medication to take its full course before assessing its effectiveness.
4. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor the client for which adverse effect?
- A. Dizziness upon standing
- B. Weight loss
- C. Bradycardia
- D. Hypotension
Correct answer: D
Rationale: The correct answer is D: Hypotension. Carvedilol, a beta-blocker, can lead to hypotension by blocking the effects of adrenaline, which can cause blood vessels to dilate and reduce blood pressure. While dizziness upon standing is a potential adverse effect of carvedilol, it is more specifically related to orthostatic hypotension, which is a form of hypotension that occurs when a person stands up from a sitting or lying position. Weight loss and bradycardia are not typically associated with carvedilol use. Therefore, the nurse should primarily monitor for hypotension in a client taking carvedilol.
5. A client is prescribed an antibiotic for a urinary tract infection (UTI). What instruction should the practical nurse provide to the client to ensure the effectiveness of the medication?
- A. Take the medication with food.
- B. Increase fluid intake.
- C. Complete the full course of the medication.
- D. Avoid dairy products.
Correct answer: C
Rationale: The practical nurse should instruct the client to complete the full course of the antibiotic to ensure the infection is fully treated and to prevent the development of antibiotic resistance. Completing the full course of antibiotics helps to eradicate the infection completely and reduces the risk of bacteria developing resistance to the medication. Choices A, B, and D are not directly related to ensuring the effectiveness of the antibiotic. While taking medication with food or increasing fluid intake can be beneficial in general, the crucial instruction in this case is to complete the full course of the antibiotic.
