Nursing Elites

1. A healthcare provider is administering a Dopamine infusion at a low dose to a client who has 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, acts on beta1 receptors in the heart, leading to increased myocardial contractility. This positive inotropic effect results in improved cardiac output, which is beneficial for a client with severe heart failure. Dopamine does not typically cause lowered heart rate, decreased conduction through the AV node, or vasoconstriction of renal blood vessels at low doses.

2. A client is receiving Enoxaparin for the prevention of deep vein thrombosis. Which of the following actions should the nurse take?

• A. Massage the injection site after administration.
• B. Administer the medication intramuscularly.
• C. Administer the medication into the subcutaneous tissue.
• D. Administer the medication into the deltoid muscle.

Correct answer: C

Rationale: Enoxaparin, a medication used for preventing deep vein thrombosis, should be administered into the subcutaneous tissue, typically in the abdomen. Administering the medication intramuscularly (Choice B) or into the deltoid muscle (Choice D) is incorrect because Enoxaparin is specifically formulated for subcutaneous administration. Massaging the injection site after administration (Choice A) is contraindicated as it may lead to tissue damage and affect the absorption of the medication. Therefore, the correct action is to administer the medication into the subcutaneous tissue as directed.

3. A client with cancer is prescribed methotrexate. Which supplement should the healthcare provider recommend to reduce the risk of methotrexate toxicity?

• A. Folic acid
• B. Magnesium
• C. Vitamin D
• D. Iron

Correct answer: A

Rationale: The correct answer is folic acid. Methotrexate is a folic acid antagonist, and supplementing with folic acid can help reduce the risk of methotrexate toxicity. Folic acid supplementation is commonly recommended to counteract the effects of methotrexate on folate metabolism. Magnesium, Vitamin D, and Iron are not specifically indicated to reduce the risk of methotrexate toxicity and therefore are incorrect choices in this scenario.

4. When educating a client with a new prescription for Atorvastatin to treat Hyperlipidemia, which instruction should the nurse include?

• A. Take this medication in the morning.
• B. Avoid drinking grapefruit juice.
• C. Increase your intake of green, leafy vegetables.
• D. Expect your stools to turn clay-colored.

Correct answer: B

Rationale: The correct instruction for the nurse to include when educating a client with a new prescription for Atorvastatin to treat Hyperlipidemia is to avoid drinking grapefruit juice. Grapefruit juice can increase the blood levels of atorvastatin, leading to an elevated risk of serious side effects such as liver damage and muscle problems. It is essential for the client to be aware of this potential interaction and to follow the nurse's advice to avoid grapefruit juice while taking Atorvastatin. Choices A, C, and D are incorrect. Taking Atorvastatin in the morning is a common recommendation but not the priority over avoiding grapefruit juice. Increasing intake of green, leafy vegetables is generally a healthy dietary choice but is not specific to the medication. Expecting stools to turn clay-colored is not a common side effect of Atorvastatin.

5. When reviewing a client's health record, a healthcare professional notes that the client is experiencing episodes of hypokalemia. Which of the following medications should be identified as a cause of the client's hypokalemia?

• A. Captopril
• B. Lisinopril
• C. Furosemide
• D. Spironolactone

Correct answer: C

Rationale: Furosemide, a loop diuretic, can lead to hypokalemia by increasing the excretion of potassium in the urine. This potassium loss can result in lower-than-normal levels of potassium in the body, leading to hypokalemia.
