1. Which drug classes are NOT typically used to treat angina?
- A. Calcium channel blockers
- B. Organic nitrates
- C. Alpha blockers
- D. Beta blockers
Correct answer: C
Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.
2. A client is starting Simvastatin. Which of the following information should be included in the teaching?
- A. Take this medication in the evening.
- B. Change positions slowly when rising from a chair.
- C. Maintain a steady intake of green leafy vegetables.
- D. Consume no more than 1 L/day of fluid.
Correct answer: A
Rationale: The correct answer is to take simvastatin in the evening. This timing is recommended because nighttime is when the most cholesterol is synthesized in the body. By taking statin medications in the evening, it can enhance their effectiveness in reducing cholesterol levels.
3. When assessing a client taking Lithium Carbonate for Bipolar disorder, which finding should the nurse recognize as a possible indication of toxicity to this medication?
- A. Severe hypertension
- B. Coarse tremors
- C. Constipation
- D. Muscle spasm
Correct answer: B
Rationale: The correct answer is B: Coarse tremors. Coarse tremors are a common sign of Lithium toxicity. Monitoring for tremors is crucial as they can indicate a potentially serious complication that requires immediate intervention. While other options such as severe hypertension, constipation, and muscle spasm may be symptoms of various conditions, they are not typically associated with Lithium toxicity. Severe hypertension is not a common sign of Lithium toxicity; constipation is not a typical symptom of Lithium toxicity either, and muscle spasm is not a direct indicator of Lithium toxicity.
4. Which of the following medications is a bronchodilator?
- A. Albuterol
- B. Omeprazole
- C. Ondansetron
- D. Senna
Correct answer: A
Rationale: Albuterol is classified as a bronchodilator, which is commonly used to treat conditions like asthma by relaxing the muscles in the airways and increasing airflow to the lungs. Omeprazole is a proton pump inhibitor used to reduce stomach acid production, while ondansetron is an anti-nausea medication, and senna is a laxative.
5. A healthcare professional in a provider's office is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: The correct answer is C: Potassium 3.4 mEq/L. Potassium 3.4 mEq/L is below the expected reference range and puts a client at risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, especially in older clients taking Digoxin, as potassium plays a crucial role in the heart's electrical activity. Choices A and B are related to calcium levels, which do not directly increase the risk of Digoxin toxicity. Choice D, Potassium 4.8 mEq/L, is within the expected reference range and would not increase the risk of Digoxin toxicity.
