ATI Proctored Pharmacology Test
1. 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.
2. A healthcare professional is preparing to administer acetaminophen 650 mg PO every 6 hr PRN for pain. The amount available is acetaminophen liquid 500 mg/5 mL. How many mL should the healthcare professional administer per dose?
- A. 6.5 mL
- B. 7 mL
- C. 5 mL
- D. 8 mL
Correct answer: A
Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the healthcare professional should administer 6.5 mL of acetaminophen per dose to achieve the desired 650 mg dose for pain relief. Choice A is correct because it accurately calculates the volume required based on the concentration of the liquid acetaminophen. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the concentration of the liquid medication and the desired dose.
3. What is a common side effect that typically occurs with the initial therapy of Nitroglycerine as a result of increased vasodilation?
- A. Abdominal cramps
- B. Calf pain
- C. Headache
- D. Blurred vision
Correct answer: C
Rationale: Headache is a common side effect associated with the initial therapy of Nitroglycerine due to its vasodilatory properties. The vasodilation caused by Nitroglycerine leads to relaxation of blood vessels, including those in the head, which can result in headaches. This side effect is considered normal and is often transient, diminishing with continued use of the medication.
4. When caring for a client prescribed Digoxin, which finding should the nurse monitor to assess for potential toxicity?
- A. Bradycardia
- B. Hypertension
- C. Hypoglycemia
- D. Hypercalcemia
Correct answer: A
Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin, a cardiac glycoside, can lead to toxic effects such as bradycardia, which is a slow heart rate. Therefore, the nurse should closely monitor the client's heart rate for any significant decreases, as this could indicate Digoxin toxicity and prompt further intervention. Choices B, C, and D are incorrect because Digoxin toxicity typically presents with bradycardia, not hypertension, hypoglycemia, or hypercalcemia.
5. A healthcare provider is reviewing the health record of a client who asks about using Propranolol to treat hypertension. The provider should recognize which of the following conditions is a contraindication for taking propranolol?
- A. Asthma
- B. Glaucoma
- C. Hypertension
- D. Tachycardia
Correct answer: A
Rationale: The correct answer is A: Asthma. Propranolol is a nonselective beta-adrenergic blocker that blocks both beta1 and beta2 receptors. Blockade of beta2 receptors in the lungs causes bronchoconstriction, making it contraindicated in clients with asthma. Using propranolol in asthma can exacerbate bronchoconstriction and potentially lead to respiratory distress or exacerbation of asthma symptoms. Choices B, C, and D are incorrect. Glaucoma, hypertension, and tachycardia are not contraindications for taking propranolol. In fact, propranolol is commonly used to treat hypertension and tachycardia.
