1. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?
- A. These medications work by blocking HIV entry into cells.
- B. These medications work by weakening the cell wall of the HIV virus.
- C. These medications work by inhibiting enzymes to prevent HIV replication.
- D. These medications work by preventing protein synthesis within the HIV cell.
Correct answer: C
Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.
2. A nurse orienting a newly licensed nurse is reviewing the procedure for taking a telephone prescription. Which of the following statements should the nurse identify as an indication that the newly licensed nurse understands the process?
- A. A second nurse enters the prescription into the client's medical record.
- B. Another nurse should listen to the phone call.
- C. The provider can clarify the prescription when he signs the health record.
- D. I should omit the 'read back' if this is a one-time prescription.
Correct answer: B
Rationale: The correct answer is B: 'Another nurse should listen to the phone call.' When taking a telephone prescription, having another nurse listen to the phone call is essential to prevent errors in communication. This process helps ensure accuracy and reduces the risk of misinterpretation. Choice A is incorrect because entering the prescription into the client's medical record is not related to verifying the accuracy of the telephone prescription. Choice C is incorrect as the provider clarifying the prescription upon signing the health record doesn't address the immediate need for verification during the phone call. Choice D is incorrect because the 'read back' is a crucial step in confirming the accuracy of all prescriptions, regardless of whether they are one-time or recurring.
3. A client is prescribed Diltiazem. Which of the following findings should the nurse monitor?
- A. Tachycardia
- B. Bradycardia
- C. Hypertension
- D. Hyperkalemia
Correct answer: B
Rationale: Diltiazem is a calcium channel blocker that can cause bradycardia as an adverse effect due to its negative chronotropic properties, slowing down the heart rate. Therefore, the nurse should monitor the client for signs of bradycardia by regularly assessing the heart rate to prevent potential complications. Monitoring for tachycardia (choice A) is incorrect as diltiazem typically does not cause tachycardia. Hypertension (choice C) is not a typical finding to monitor for with diltiazem use. Hyperkalemia (choice D) is not directly associated with diltiazem administration.
4. A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Hypokalemia potentiates the effects of Digoxin, making the heart more sensitive to its toxic effects. Monitoring and correcting electrolyte imbalances, especially low potassium levels, are crucial to prevent adverse effects of digoxin therapy. Calcium levels do not directly influence digoxin toxicity, so choices A and B are incorrect. High potassium levels, as in choice D, are less likely to increase the risk of digoxin toxicity compared to low potassium levels.
5. A client has a new prescription for Propranolol. Which of the following statements should the nurse include in teaching the client?
- A. You may experience a rapid heart rate while taking this medication.
- B. Take the medication with food.
- C. Avoid sudden changes in position.
- D. Increase your intake of high-sodium foods.
Correct answer: C
Rationale: The correct statement to include when teaching a client about Propranolol is to avoid sudden changes in position. Propranolol, a beta-blocker, can lead to dizziness and lightheadedness, particularly when changing positions. Therefore, clients should be advised to change positions slowly to prevent falls and related injuries. Choice A is incorrect because Propranolol actually helps lower heart rate and blood pressure. Choice B is not a specific requirement for taking Propranolol. Choice D is also incorrect as increasing high-sodium foods is not recommended with Propranolol which can affect blood pressure control.
