1. When administering Phenytoin, what should you monitor?
- A. Behavior
- B. Therapeutic blood levels
- C. For signs of Stevens-Johnson syndrome
- D. All of the above
Correct answer: D
Rationale: When administering Phenytoin, monitoring the patient's behavior is important to assess for any changes that may indicate adverse effects. Monitoring therapeutic blood levels helps ensure the medication is within the effective range and not causing toxicity. Additionally, being vigilant for signs of Stevens-Johnson syndrome, a severe skin reaction associated with Phenytoin use, is crucial for early detection and intervention. Therefore, monitoring behavior, therapeutic blood levels, and for signs of Stevens-Johnson syndrome are all essential when administering Phenytoin.
2. A client with a new prescription for an antihypertensive medication is being provided discharge instructions by a nurse. Which of the following statements should the nurse give?
- A. Be sure to limit your potassium intake while taking the medication.
- B. You should check your blood pressure every 8 hours while taking this medication.
- C. Your medication dosage will be increased if you develop tachycardia.
- D. Change positions slowly when you move from sitting to standing.
Correct answer: D
Rationale: The correct statement for the nurse to provide is to instruct the client to change positions slowly when moving from sitting to standing. This is crucial because antihypertensive medications can cause orthostatic hypotension, leading to dizziness or lightheadedness when changing positions quickly. Checking blood pressure every 8 hours is unnecessary and could lead to over-monitoring. There is no direct relationship between the medication and potassium intake. Increasing the medication dosage due to tachycardia is not a typical response and may not be accurate.
3. A nurse reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the nurse take?
- A. Obtain a blood specimen immediately prior to administering the next dose of medication.
- B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
- C. Ask the client to provide a urine specimen after the next dose of medication.
- D. Administer the medication and obtain a blood specimen 30 minutes later.
Correct answer: A
Rationale: To verify the trough levels of a medication accurately, the nurse should obtain a blood specimen immediately before administering the next dose of the medication. The trough level represents the lowest concentration of the medication in the bloodstream, typically right before the next dose is due. This timing ensures an accurate assessment of the drug's concentration in the body at its lowest point, aiding in determining the drug's effectiveness and potential toxicity levels. Choice B is incorrect because waiting for 24 hours would not provide the trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect as obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level.
4. A healthcare professional is caring for a client who has a new prescription for Lisinopril. Which of the following laboratory values should the professional monitor?
- A. Serum potassium
- B. Serum sodium
- C. Serum calcium
- D. Serum magnesium
Correct answer: A
Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing the excretion of potassium in the kidneys. Monitoring serum potassium levels is essential to prevent complications such as cardiac arrhythmias. Therefore, the healthcare professional should closely monitor the client's serum potassium levels when they are on Lisinopril. Choices B, C, and D are incorrect because Lisinopril primarily affects potassium levels due to its mechanism of action as an ACE inhibitor. Serum sodium, calcium, and magnesium levels are not typically affected by Lisinopril in the same way as potassium.
5. A client is taking Amiodarone to treat Atrial Fibrillation. Which of the following findings is a manifestation of Amiodarone toxicity?
- A. Light yellow urine
- B. Report of tinnitus
- C. Productive cough
- D. Blue-gray skin discoloration
Correct answer: D
Rationale: Blue-gray skin discoloration is a common sign of Amiodarone toxicity, known as blue-gray discoloration, which can affect areas like the face, neck, or hands. It is important to monitor for this side effect, as it can be a visible indicator of potential toxicity. Choices A, B, and C are incorrect. Light yellow urine is not typically associated with Amiodarone toxicity. Tinnitus is not a common manifestation of Amiodarone toxicity. A productive cough is not a recognized symptom of Amiodarone toxicity.
