1. What is the expected pharmacological action of propranolol?

A. Block stimulation of beta1 receptors
B. Alter water and electrolyte transport in the large intestine
C. Block stimulation of beta2 receptors
D. Both A and C are correct

Correct answer: D

Rationale: Propranolol exerts its pharmacological action by blocking stimulation of both beta1 and beta2 receptors. By doing so, it leads to decreased heart rate and blood pressure. Therefore, both options A and C are correct as propranolol affects both types of beta receptors. Choice B is incorrect as propranolol does not alter water and electrolyte transport in the large intestine.

2. What is the therapeutic use of Alprazolam?

A. Preventing thrombus formation
B. Relief of anxiety
C. Decreasing the risk of stroke
D. Increasing urinary output

Correct answer: B

Rationale: The therapeutic use of Alprazolam is for the relief of anxiety. Alprazolam belongs to a class of medications known as benzodiazepines, which are commonly prescribed to manage anxiety disorders and panic attacks. It works by enhancing the effects of a natural chemical in the body (GABA) to produce a calming effect on the brain and nerves, thereby alleviating symptoms of anxiety.

3. A school-age child has a new prescription for Atomoxetine. The nurse should monitor the client for which of the following adverse effects of this medication?

A. Kidney toxicity
B. Liver damage
C. Seizure activity
D. Adrenal insufficiency

Correct answer: B

Rationale: Liver damage is an adverse effect of Atomoxetine. The nurse should monitor for manifestations such as jaundice, upper abdominal tenderness, darkening of urine, and elevated liver enzymes. It is crucial to be vigilant for signs of liver damage to ensure early detection and intervention to prevent further complications. Kidney toxicity is not a common adverse effect of Atomoxetine. Seizure activity and adrenal insufficiency are also not typically associated with this medication.

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

A. Increase your intake of bran fiber.
B. Monitor your heart rate before taking the medication.
C. Take the medication with antacids.
D. Avoid drinking orange juice.

Correct answer: B

Rationale: When a client is prescribed Digoxin, it is essential to monitor their heart rate before each dose. Changes such as a heart rate below 60 bpm should be reported to the healthcare provider promptly. This is crucial because Digoxin can affect heart rhythm, and monitoring the heart rate helps in identifying any potential issues early on.

5. Which of the following conditions is not treated with epinephrine?

A. Renal disease
B. Asthma
C. Hypotension
D. Glaucoma

Correct answer: A

Rationale: Epinephrine is not used to treat renal disease. Epinephrine is commonly used to treat conditions like asthma, hypotension, and glaucoma, but it is not an appropriate treatment for renal disease. Renal disease requires specific management strategies that do not involve the use of epinephrine.
