Nursing Elites

1. What is a chemical reaction between drugs before their administration or absorption known as?

• A. a drug incompatibility
• B. a side effect
• C. an adverse event
• D. an allergic response

Correct answer: A

Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly happens when drug solutions are mixed before intravenous administration, but it can also occur with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses occur after the administration and absorption of drugs, not prior to it.

2. The newborn nursery is filled to capacity. Which newborn should the nurse assess first?

• A. A three-hour-old just waking up after a period of sleep
• B. A two-day-old crying loudly
• C. A three-day-old two hours after circumcision
• D. A one-hour-old sucking his fist

Correct answer: A

Rationale: The most critical time for assessment in a newborn is during the second period of reactivity, which occurs approximately 3-5 hours after delivery. During this phase, newborns are more likely to gag on mucus and aspirate, making it crucial for the nurse to assess their respiratory status first. Choice A indicates a newborn in this critical phase, requiring immediate assessment for potential airway compromise or respiratory distress. Choices B, C, and D do not present an immediate need for assessment related to airway compromise or respiratory distress.

3. Which of the following is not a primary function of the kidneys?

• A. blood pressure control
• B. vitamin D activation
• C. erythropoietin production
• D. reabsorption of waste products

Correct answer: D

Rationale: The correct answer is reabsorption of waste products because the kidneys excrete waste products rather than reabsorbing them. Choices A, B, and C are indeed primary functions of the kidneys. The kidneys play a crucial role in regulating blood pressure, activating vitamin D, and producing erythropoietin, which stimulates red blood cell production. Therefore, the primary role of the kidneys is to filter blood, remove waste products, regulate fluid balance, and maintain electrolyte balance.

4. When treating anemia in clients with renal failure, erythropoietin should be given in conjunction with:

• A. iron, folic acid, and B12.
• B. an increase in protein in the diet.
• C. vitamins A and C.
• D. an increase in calcium in the diet.

Correct answer: A

Rationale: Erythropoietin is used to stimulate red blood cell production in clients with renal failure. To effectively increase red blood cell production, adequate levels of iron, folic acid, and B12 are necessary. These nutrients play crucial roles in erythropoiesis. Choices B, an increase in protein in the diet, is not directly related to enhanced erythropoiesis and can potentially worsen uremia. Choices C and D, vitamins A and C, and an increase in calcium in the diet, are not directly involved in red blood cell production and are not essential in this context.

5. The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:

• A. Manage peripheral edema
• B. Improve right ventricular function
• C. Increase pulmonary pressure
• D. Constrict the pulmonary vessels

Correct answer: B

Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension. Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action. Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation. Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.
