1. 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.

2. Which medication is used as a bronchodilator?

• A. Warfarin
• B. Lovastatin
• C. Albuterol
• D. Valproate

Correct answer: C

Rationale: Albuterol is the correct answer. It is a medication commonly used as a bronchodilator to treat conditions such as asthma. Albuterol works by relaxing the muscles in the airways, allowing better airflow and making breathing easier for individuals with respiratory conditions. Warfarin (Choice A) is an anticoagulant used to prevent blood clots, Lovastatin (Choice B) is a medication used to lower cholesterol levels, and Valproate (Choice D) is used to treat seizures and bipolar disorder. These medications are not bronchodilators and are used for different medical conditions.

3. What is the therapeutic class of Valproate?

• A. Anticoagulant
• B. Antianxiety, benzodiazepines
• C. Anticonvulsant, vascular headache suppressant
• D. Mood stabilizer

Correct answer: C

Rationale: Valproate belongs to the therapeutic class of anticonvulsants. It is primarily used to manage seizures but is also effective in treating vascular headaches. Therefore, it is not classified as an anticoagulant, antianxiety medication, or mood stabilizer. Option A, anticoagulant, is incorrect as valproate does not have anticoagulant properties. Option B, antianxiety benzodiazepines, is incorrect as valproate is not primarily used to treat anxiety disorders with benzodiazepines. Option D, mood stabilizer, is incorrect as valproate is not classified as a mood stabilizer, although it can be used in some cases for mood disorders, its primary therapeutic class is anticonvulsant.

4. A healthcare professional in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?

• A. Isosorbide
• B. Phenytoin
• C. Metronidazole
• D. Prednisone

Correct answer: A

Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Isosorbide is a nitrate that can potentiate the hypotensive effects of sildenafil, leading to a dangerous drop in blood pressure. Therefore, it is essential to avoid concurrent use of isosorbide and sildenafil to prevent adverse effects. Phenytoin, metronidazole, and prednisone do not have significant interactions with sildenafil and are not contraindicated when used together.

5. A client is being discharged with a new prescription for Fluoxetine for PTS. Which of the following statements should the nurse include in the teaching?

• A. You may experience a decreased desire for intimacy while taking this medication.
• B. You should take this medication in the morning to avoid sleep disturbances.
• C. To minimize urinary adverse effects, ensure you urinate before taking this medication.
• D. It is recommended to wear sunglasses outdoors due to the light sensitivity caused by this medication.

Correct answer: A

Rationale: The correct statement for the nurse to include in the teaching is that the client may experience a decreased desire for intimacy while taking Fluoxetine for PTS. This is important because Fluoxetine, an SSRI used to treat PTS, can lead to decreased libido as a potential adverse effect. Choices B, C, and D are incorrect because they do not address the specific side effect associated with Fluoxetine and are not directly relevant to the medication's effects for this patient.
