1. What is the expected pharmacological action of propranolol?

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. A client has a new prescription for Clozapine. Which of the following statements should the nurse include in the teaching?

Correct answer: D

Rationale: Clozapine carries a risk for fatal agranulocytosis. To monitor for this serious adverse effect, it is crucial to check the client's white blood cell count weekly while they are on clozapine therapy.

3. When caring for a client prescribed warfarin, which laboratory test should the nurse monitor to evaluate the therapeutic effect of the medication?

Correct answer: D

Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting. Choice A (aPTT) is incorrect because while it measures the clotting time, it is not the preferred test for monitoring warfarin therapy. Choice B (Platelet count) is incorrect as it assesses the number of platelets and not the medication's therapeutic effect. Choice C (BUN) is unrelated to monitoring the effects of warfarin therapy and is primarily used to assess kidney function.

4. A client has a new prescription for a Nitroglycerin transdermal patch for Angina Pectoris. Which of the following instructions should the nurse include?

Correct answer: A

Rationale: The correct instruction is to remove the nitroglycerin patch each evening to prevent tolerance. This allows for a 10- to 12-hour nitrate-free period daily, reducing the risk of developing tolerance to nitroglycerin. Cutting the patch in half is not recommended because it can alter the dosing and absorption rate, leading to inadequate symptom control. Taking off the patch for a headache is not necessary as headaches are a common side effect that may improve with continued use. Applying a new patch every 48 hours is not correct as it may not provide continuous symptom relief for angina.

5. A toddler is being admitted to the hospital after an Acetaminophen overdose. Which of the following medications should the nurse anticipate administering to this patient?

Correct answer: A

Rationale: In cases of Acetaminophen overdose, acetylcysteine is the antidote of choice. Acetylcysteine helps prevent liver damage by replenishing depleted glutathione levels, which is essential for detoxifying acetaminophen metabolites. Pegfilgrastim is a medication used to stimulate white blood cell production, Misoprostol is a medication for preventing stomach ulcers, and Naltrexone is used for treating opioid addiction and alcoholism, but none of these are indicated for Acetaminophen overdose.
