1. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?

• A. Lowered heart rate
• B. Increased myocardial contractility
• C. Decreased conduction through the AV node
• D. Vasoconstriction of renal blood vessels

Correct answer: B

Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.

2. Following a stroke, a client has been started on clopidogrel (Plavix). Why is this medication being administered?

• A. To prevent stroke in high-risk patients, such as those with prosthetic heart valves
• B. To decrease blood pressure
• C. To increase heart rate
• D. To provide antiplatelet activity in patients who cannot tolerate aspirin

Correct answer: D

Rationale: Clopidogrel (Plavix) is an antiplatelet medication that inhibits platelet aggregation, reducing the risk of blood clots. It is commonly used in patients who have had a stroke and cannot tolerate aspirin due to allergies or intolerances. Choosing clopidogrel in these cases helps prevent further clot formation and reduces the risk of recurrent strokes.

3. Which of the following is not a side effect of Sympathoplegics (Clonidine)?

• A. Hypertension
• B. Difficulty breathing
• C. Dry oral cavity
• D. Lethargic behavior

Correct answer: A

Rationale: The correct answer is A. Clonidine, a Sympathoplegic, typically causes hypotension rather than hypertension. The other side effects associated with Clonidine include dry oral cavity, lethargic behavior, and difficulty breathing, making them incorrect choices in this context.

4. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?

• A. Use an electric shaver to remove excess hair on the extremity.
• B. Select the antecubital area to insert the IV catheter.
• C. Distend the veins by using a blood pressure cuff.
• D. Instruct the client to keep the extremity still during the procedure.

Correct answer: C

Rationale: Distending the veins using a blood pressure cuff is essential for facilitating visualization and access to the veins during IV catheter insertion. This technique helps healthcare professionals identify suitable veins, reducing the risk of complications like infiltration or hematoma formation. Using an electric shaver to remove hair on the extremity (Choice A) may increase the risk of micro-cuts and introduce infection. Selecting the antecubital area (Choice B) may not always be appropriate, as vein condition and accessibility vary among older adult clients. Instructing the client to keep the extremity still (Choice D) is important but is not directly related to preparing for IV therapy.

5. A healthcare professional is preparing to administer furosemide 80 mg PO daily. The available furosemide oral solution is 10 mg/1 mL. How many mL should the healthcare professional administer?

• A. 8 mL
• B. 10 mL
• C. 6 mL
• D. 12 mL

Correct answer: A

Rationale: To determine the volume to administer, divide the desired dose by the available concentration. In this case, 80 mg divided by 10 mg/mL equals 8 mL. Therefore, the healthcare professional should administer 8 mL of furosemide oral solution. Choice B, 10 mL, is incorrect as it does not reflect the accurate calculation. Choices C and D, 6 mL and 12 mL respectively, are also incorrect as they do not match the correct calculation based on the provided concentration and dose.
