1. A client with angina is seeking a prescription for sildenafil to manage erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?
- A. Aspirin
- B. Isosorbide
- C. Clopidogrel
- D. Atorvastatin
Correct answer: B
Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.
2. A client is taking metformin for type 2 diabetes. Which of the following findings should indicate to the nurse that the medication is effective?
- A. Increased urine output
- B. Decreased fasting blood glucose
- C. Decreased hemoglobin A1C
- D. Decreased polyuria
Correct answer: C
Rationale: A decrease in hemoglobin A1C is a more specific indicator of metformin's effectiveness in controlling blood glucose levels over a longer period compared to fasting blood glucose levels. Hemoglobin A1C reflects average blood sugar levels over the past 2-3 months, providing a more comprehensive view of glycemic control. Increased urine output (choice A) is not a direct indicator of metformin's effectiveness and can be influenced by various factors. Decreased fasting blood glucose (choice B) can fluctuate due to various reasons and may not provide a reliable long-term assessment of metformin's efficacy. Decreased polyuria (choice D) refers to a symptom rather than a direct measure of metformin's effectiveness in managing diabetes.
3. A client is taking oral Oxycodone and Ibuprofen. The nurse should identify that an interaction between these two medications will cause which of the following findings?
- A. A decrease in serum levels of ibuprofen, possibly leading to a need for increased doses of this medication.
- B. A decrease in serum levels of oxycodone, possibly leading to a need for increased doses of this medication.
- C. An increase in the expected therapeutic effect of both medications.
- D. An increase in expected adverse effects for both medications.
Correct answer: C
Rationale: The interaction between oxycodone and ibuprofen results in an increase in the expected therapeutic effect of both medications. Oxycodone is a narcotic analgesic, while ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID). They work through different mechanisms but complement each other in pain management. When taken together, they can enhance the pain-relieving effects of each other, providing better pain relief for the client.
4. When a client is prescribed hydrochlorothiazide, what adverse effect should they monitor for as instructed by the nurse?
- A. Hyponatremia
- B. Ototoxicity
- C. Hypoglycemia
- D. Hyperkalemia
Correct answer: A
Rationale: Hyponatremia is a critical adverse effect associated with hydrochlorothiazide use. This medication is a diuretic that can lead to excessive loss of sodium and water from the body, potentially causing low sodium levels and resulting in hyponatremia. Monitoring for signs and symptoms of hyponatremia, such as confusion, headache, weakness, and muscle cramps, is essential to prevent serious complications. Ototoxicity (choice B) is not a common adverse effect of hydrochlorothiazide. Hypoglycemia (choice C) and hyperkalemia (choice D) are also not typically associated with hydrochlorothiazide use.
5. What is one therapeutic use for nitroglycerin?
- A. Relief or prevention of anginal attacks
- B. Diuresis and mobilization of excess fluid
- C. Decreasing nausea and vomiting
- D. Relief of anxiety
Correct answer: A
Rationale: Nitroglycerin is primarily used for the relief or prevention of anginal attacks. It works by dilating blood vessels, increasing blood flow and oxygen to the heart muscle, thereby relieving chest pain caused by angina. The medication is not indicated for diuresis, antiemetic effects, or anxiety relief. Therefore, choices B, C, and D are incorrect as they do not reflect the therapeutic use of nitroglycerin.
