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. Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?

• A. Heparin
• B. Alprazolam
• C. Digoxin
• D. Levothyroxine

Correct answer: C

Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.

3. A healthcare professional is preparing to administer morphine 4 mg IV to a client. Available is morphine 10 mg/mL. How many mL should the healthcare professional administer?

• A. 0.2 mL
• B. 0.4 mL
• C. 0.6 mL
• D. 0.8 mL

Correct answer: B

Rationale: To administer 4 mg from a solution of 10 mg/mL, the healthcare professional should administer 0.4 mL. The calculation is done by dividing the desired dose (4 mg) by the concentration of the solution (10 mg/mL), which equals 0.4 mL. Choice A (0.2 mL) is incorrect because it is half of the correct calculation. Choice C (0.6 mL) is incorrect because it is 50% more than the correct calculation. Choice D (0.8 mL) is incorrect because it exceeds the correct calculation.

4. When assessing a client with chronic Neutropenia receiving Filgrastim, what action should the nurse take to evaluate for an adverse effect of the medication?

• A. Assess for bone pain.
• B. Assess for right lower quadrant pain.
• C. Auscultate for crackles in the bases of the lungs.
• D. Auscultate the chest to listen for a heart murmur.

Correct answer: A

Rationale: The correct action when assessing a client receiving Filgrastim for chronic Neutropenia is to assess for bone pain. Bone pain is a known dose-related adverse effect of Filgrastim. Acetaminophen or opioid analgesics can be used to manage bone pain if necessary. Assessing for other types of pain, lung crackles, or heart murmurs would not be specific to the adverse effects of Filgrastim.

5. A client with breast cancer is being taught by a nurse about the adverse effects of chemotherapy. Which of the following statements should the nurse include?

• A. You should use a soft-bristled toothbrush to prevent bleeding.
• B. You should avoid contact with individuals who recently received live virus vaccines.
• C. You should take aspirin for minor aches and pains.
• D. You should consume a diet low in protein to reduce the risk of renal damage.

Correct answer: A

Rationale: The nurse should instruct the client to use a soft-bristled toothbrush to prevent bleeding, which can occur due to chemotherapy-induced thrombocytopenia. Chemotherapy can decrease platelet counts, leading to an increased risk of bleeding. Using a soft-bristled toothbrush can help prevent gum bleeding and oral trauma. Choices B, C, and D are incorrect. Avoiding contact with individuals who recently received live virus vaccines is crucial to prevent infections in immunocompromised clients. Aspirin should be avoided due to its blood-thinning effects that can increase the risk of bleeding. A diet low in protein is not recommended as cancer clients often require adequate protein intake for healing and recovery.
