1. What is the primary use of lithium?

A. Lower blood glucose
B. Slow the heart rate
C. Stabilize mood
D. Heal ulcers

Correct answer: C

Rationale: The correct answer is C: Stabilize mood. Lithium is primarily used to stabilize mood, especially in conditions like bipolar disorder. It helps in reducing the frequency and severity of manic episodes, making it an essential medication for mood stabilization. Choices A, B, and D are incorrect as lithium is not used to lower blood glucose, slow the heart rate, or heal ulcers.

2. A client is receiving Morphine IV for pain management. Which of the following actions should the nurse take to monitor for adverse effects?

A. Monitor the client's respiratory rate every 15 minutes.
B. Monitor the client's blood pressure every 30 minutes.
C. Monitor the client's oxygen saturation every hour.
D. Monitor the client's heart rate every 5 minutes.

Correct answer: A

Rationale: The correct action for the nurse to monitor for adverse effects of Morphine IV is to check the client's respiratory rate every 15 minutes. Respiratory depression is a potentially life-threatening adverse effect of Morphine. Monitoring the respiratory rate frequently allows for early detection and intervention if needed. Monitoring blood pressure, oxygen saturation, or heart rate alone may not provide early signs of respiratory depression, which is a critical adverse effect of Morphine IV.

3. A client has a new prescription for Ranitidine. Which of the following instructions should the nurse include?

A. Take the medication with an antacid.
B. Avoid drinking coffee while taking this medication.
C. Take the medication at bedtime.
D. Stop the medication if you develop a headache.

Correct answer: C

Rationale: The correct instruction for a client prescribed Ranitidine is to take the medication at bedtime. Ranitidine is best taken at bedtime as it helps decrease the production of stomach acid during the night, providing optimal relief for conditions like heartburn or acid indigestion.

4. A client has difficulty swallowing medications and is prescribed enteric-coated aspirin PO once daily. The client asks if the medication can be crushed to make it easier to swallow. Which of the following responses should the nurse provide?

A. Crushing the medication might cause you to have a stomachache or indigestion.
B. Crushing the medication is a good idea, and I can mix it in some ice cream for you.
C. Crushing the medication would release all the medication at once, rather than over time.
D. Crushing is unsafe, as it destroys the ingredients in the medication.

Correct answer: A

Rationale: Crushing an enteric-coated medication can cause it to break down in the stomach instead of the intestines, potentially leading to gastrointestinal distress like stomachache or indigestion. It is important to take enteric-coated medications whole to ensure they are properly absorbed in the intestines and to prevent irritation to the stomach.

5. What is the correct definition of drug absorption?

A. Movement of a drug from the site of administration to various tissues of the body
B. Describes the absorption, distribution, metabolism, and excretion of drugs
C. These types of drugs can be taken over the counter
D. This addresses how various drugs affect different forms of the body

Correct answer: A

Rationale: The correct definition of drug absorption is the movement of a drug from the site of administration into various tissues of the body. It is the process by which a drug is taken up and enters the systemic circulation. Choice B describes the pharmacokinetics of drugs, including absorption, distribution, metabolism, and excretion, but it is not a specific definition of drug absorption. Choice C is unrelated to drug absorption, as it refers to over-the-counter drugs. Choice D is too vague and does not specifically address the process of drug absorption.
