1. What is a desired outcome of the drug Phenytoin?

• A. Decrease symptoms of PTSD
• B. Resolution of signs of infection
• C. Decrease or cessation of seizures without excessive sedation
• D. Prevention or relief of bronchospasm

Correct answer: C

Rationale: The correct answer is C: Decrease or cessation of seizures without excessive sedation. Phenytoin is primarily used as an antiepileptic medication to manage and prevent seizures. It does not directly impact symptoms of PTSD (Choice A), resolution of signs of infection (Choice B), or prevention or relief of bronchospasm (Choice D). Therefore, the desired outcome of Phenytoin is to control seizures effectively while avoiding excessive sedation.

2. A client has been prescribed an ACE Inhibitor for hypertension. Which of the following instructions should be included by the healthcare provider?

• A. Avoid salt substitutes.
• B. Take this medication at bedtime.
• C. Avoid foods high in potassium.
• D. Limit your fluid intake.

Correct answer: A

Rationale: The correct answer is to 'Avoid salt substitutes.' ACE Inhibitors can increase potassium levels, so clients should avoid salt substitutes that contain potassium to prevent hyperkalemia, which is a potential side effect of ACE Inhibitors. Choice B 'Take this medication at bedtime' is incorrect as ACE Inhibitors are usually taken in the morning to avoid nocturnal diuresis. Choice C 'Avoid foods high in potassium' is incorrect because although ACE Inhibitors can increase potassium levels, clients are generally encouraged to consume potassium-rich foods in moderation unless contraindicated. Choice D 'Limit your fluid intake' is also incorrect as ACE Inhibitors do not typically require fluid restrictions unless specified by a healthcare provider for other reasons.

3. In the management of nausea due to gastroparesis in a client with Diabetes, which of the following medications may be prescribed?

• A. Lubiprostone
• B. Metoclopramide
• C. Bisacodyl
• D. Loperamide

Correct answer: B

Rationale: Metoclopramide, as a dopamine antagonist, is commonly prescribed to manage nausea and improve gastric motility in clients with diabetic gastroparesis. By enhancing gastric emptying, it can help alleviate symptoms like bloating and nausea associated with gastroparesis. Choice A, Lubiprostone, is primarily used to treat chronic idiopathic constipation and irritable bowel syndrome with constipation, not nausea due to gastroparesis. Choice C, Bisacodyl, is a stimulant laxative used for the treatment of constipation and bowel preparation before procedures, not for nausea associated with gastroparesis. Choice D, Loperamide, is an antimotility agent used to manage diarrhea, not nausea or gastric motility issues seen in gastroparesis.

4. A healthcare professional is preparing to administer verapamil by IV bolus to a client who is experiencing cardiac dysrhythmias. For which of the following adverse effects should the healthcare professional monitor when giving this medication?

• A. Hyperthermia
• B. Hypotension
• C. Ototoxicity
• D. Muscle pain

Correct answer: B

Rationale: Verapamil is known to cause hypotension as one of its adverse effects due to its vasodilatory properties. Therefore, it is essential for the healthcare professional to monitor the client's blood pressure closely during and after administration to prevent complications such as severe hypotension. Hyperthermia, ototoxicity, and muscle pain are not commonly associated with verapamil administration, making choices A, C, and D incorrect.

5. How do ACE inhibitors work?

• A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
• B. Block stimulation of beta 1 and beta 2 at the receptor sites
• C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
• D. None of the above

Correct answer: C

Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.
