Nursing Elites

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. When should a blood sample be obtained for a peak serum level of gentamicin when administered by IV infusion for 1 hour at 0900?

• A. 1000
• B. 1030
• C. 1100
• D. 1130

Correct answer: B

Rationale: The nurse should obtain the blood sample for the peak serum level at 1030. This timing allows for 30 minutes to elapse after the completion of the 1-hour IV infusion, which is the recommended window for obtaining the peak serum level of gentamicin.

3. A client has a new prescription for Nitroglycerin to treat angina. Which of the following instructions should the nurse include?

• A. Take this medication only when chest pain occurs.
• B. Store the medication in a cool, dry place.
• C. Apply the patch to a different site each time.
• D. Avoid consuming alcohol while taking this medication.

Correct answer: C

Rationale: The correct instruction for the nurse to include is to advise the client to apply the Nitroglycerin patch to a different site each time. This is crucial to prevent skin irritation and ensure consistent absorption of the medication. Rotating application sites is important as it helps maintain the effectiveness of the treatment and reduces the risk of skin reactions. Choice A is incorrect because Nitroglycerin is often used prophylactically to prevent angina episodes rather than just for acute chest pain. Choice B is not relevant to the administration or effectiveness of the medication. Choice D, while generally a good recommendation, is not directly related to the administration of Nitroglycerin.

4. Which of the following is not a common effect of Midazolam?

• A. Amnesia
• B. Decreased respiratory function
• C. Anesthetic
• D. Dizziness

Correct answer: D

Rationale: Midazolam is a benzodiazepine commonly used for its sedative, anxiolytic, and amnestic effects. While dizziness can be a side effect of Midazolam, it is not a primary or common effect. Therefore, the correct answer is D, as it deviates from the typical effects associated with Midazolam.

5. What is the primary use of lithium?

• A. Lower blood glucose
• B. Slow the heart rate
• C. Stabilize mood
• D. Heal ulcers

Correct answer: C

Rationale: The correct answer is C: Stabilize mood. Lithium is primarily used to stabilize mood, especially in conditions like bipolar disorder. It helps in reducing the frequency and severity of manic episodes, making it an essential medication for mood stabilization. Choices A, B, and D are incorrect as lithium is not used to lower blood glucose, slow the heart rate, or heal ulcers.
