Nursing Elites

1. When taking Digoxin, low levels of what can cause toxicity?

• A. Potassium
• B. Calcium
• C. Sodium
• D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

2. A client has a new prescription for Furosemide. Which of the following instructions should be included by the nurse?

• A. Take this medication at bedtime.
• B. Avoid eating foods high in potassium.
• C. Change positions slowly.
• D. Take this medication with meals.

Correct answer: C

Rationale: The correct instruction to include when a client is prescribed Furosemide is to change positions slowly. Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and increasing the risk of falls. By advising the client to change positions slowly, the nurse helps prevent these potential adverse effects.

3. Why does a nurse on an oncology unit verify a client's current cumulative lifetime dose of doxorubicin before administering it to a client with breast cancer?

• A. Excessive doxorubicin can result in myelosuppression.
• B. Exceeding the lifetime cumulative dose limit of doxorubicin may lead to extravasation.
• C. An excess amount of doxorubicin can lead to cardiomyopathy.
• D. Exceeding the lifetime cumulative dose limit of doxorubicin may cause red-tinged urine and sweat.

Correct answer: C

Rationale: Verifying the client's current cumulative lifetime dose of doxorubicin is necessary because excessive amounts of the medication can lead to cardiomyopathy, a serious and potentially life-threatening side effect. By monitoring the cumulative dose, healthcare providers can help prevent cardiotoxicity and ensure patient safety during treatment.

4. A client has been prescribed Aspirin for prevention of cardiovascular disease. Which of the following findings indicates the medication is effective?

• A. The client has a decrease in troponin levels.
• B. The client has a regular heart rhythm.
• C. The client experiences a decrease in episodes of angina.
• D. The client's blood pressure remains stable.

Correct answer: C

Rationale: The correct answer is C. A decrease in episodes of angina is an indicator of Aspirin's effectiveness in preventing cardiovascular events. Aspirin works by inhibiting platelet aggregation, thereby reducing the formation of blood clots that could lead to angina episodes or more severe cardiovascular complications. Choices A, B, and D are incorrect because troponin levels, heart rhythm, and blood pressure are not direct indicators of Aspirin's effectiveness in preventing cardiovascular events.

5. A client has a new prescription for Aspirin for the prevention of myocardial infarction. Which of the following findings should be identified as an adverse effect?

• A. Nausea
• B. Bruising
• C. Dizziness
• D. Dry mouth

Correct answer: B

Rationale: Bruising is an adverse effect to be monitored when a client is prescribed Aspirin for the prevention of myocardial infarction due to its association with increased bleeding risk. Aspirin's antiplatelet effect can lead to bruising and other signs of bleeding, necessitating close observation to prevent complications. Nausea, dizziness, and dry mouth are not typically recognized adverse effects of Aspirin therapy for myocardial infarction prevention.
