1. What are the Therapeutic Effects of Lithium?

• A. Prevents or decreases the incidence of acute manic episodes
• B. Maintenance of blood glucose
• C. Control of hyperglycemia in diabetic patients
• D. Diminished seizure activity

Correct answer: A

Rationale: The therapeutic effect of lithium is that it prevents or decreases the incidence of acute manic episodes in patients with bipolar disorder. Lithium is commonly used as a mood stabilizer in the treatment of bipolar disorder due to its ability to reduce the frequency and severity of manic episodes. Choices B, C, and D are incorrect as lithium is not used for the maintenance of blood glucose, control of hyperglycemia in diabetic patients, or to diminish seizure activity. These effects are not associated with the use of lithium as a medication.

2. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?

• A. Four medications decrease the risk of a severe allergic reaction.
• B. Four medications reduce the chance that the bacteria will become resistant.
• C. Four medications reduce the risk of adverse reactions.
• D. Four medications decrease the chance of having a positive tuberculin skin test.

Correct answer: B

Rationale: The correct answer is B. When treating tuberculosis, using a combination of medications is crucial to reduce the risk of bacteria developing resistance to any single drug. This approach helps prevent treatment failure and ensures successful treatment outcomes. Choice A is incorrect because the primary purpose of using multiple medications is not related to allergic reactions. Choice C is incorrect as the risk reduction is mainly focused on bacterial resistance rather than adverse reactions. Choice D is not relevant as the purpose of taking multiple medications is not to affect the tuberculin skin test results.

3. A nurse is providing teaching to a client who has a new prescription for Metoprolol. Which of the following statements should the nurse include?

• A. This medication may make you feel dizzy at first.
• B. You should avoid foods that are high in fat.
• C. Take the medication in the morning.
• D. You may experience a rapid heart rate while taking this medication.

Correct answer: A

Rationale: Metoprolol, a beta-blocker, can cause dizziness, especially when starting the medication. The nurse should inform the client to change positions slowly to avoid dizziness and falls.

4. A client has a new prescription for Metronidazole to treat an infection. Which of the following instructions should the nurse include?

• A. Avoid alcohol while taking this medication.
• B. Take this medication on an empty stomach.
• C. Increase your intake of dairy products while taking this medication.
• D. Avoid direct sunlight while taking this medication.

Correct answer: A

Rationale: The correct instruction is to avoid alcohol while taking Metronidazole. This is crucial to prevent a disulfiram-like reaction, which can result in severe nausea and vomiting. Alcohol should be avoided for at least 48 hours after completing the medication course as well. Choice B is incorrect because Metronidazole can be taken with food to reduce gastrointestinal side effects. Choice C is incorrect because there is no need to increase dairy product intake while on Metronidazole. Choice D is incorrect because there is no specific instruction to avoid direct sunlight while taking this medication.

5. 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.
