Nursing Elites

1. A client presents to the emergency department with symptoms of a myocardial infarction. What should the nurse administer immediately under doctor's orders?

• A. Aspirin to prevent further blood clotting
• B. High-flow oxygen
• C. Intravenous fluids
• D. Nitroglycerin

Correct answer: A

Rationale: The correct answer is A: Aspirin to prevent further blood clotting. Administering aspirin is crucial in the immediate management of a myocardial infarction as it helps prevent further blood clot formation, which is a key component in the treatment and prevention of myocardial infarction. Oxygen therapy (Choice B) is often provided, but aspirin takes precedence due to its role in reducing clot formation. Intravenous fluids (Choice C) may be needed but are not the immediate priority in this situation. Nitroglycerin (Choice D) is commonly used for chest pain relief in myocardial infarction but is not the first medication to be administered in this scenario.

2. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

3. A client with a diagnosis of anemia is being discharged with a prescription for ferrous sulfate. What should the nurse include in the teaching plan?

• A. Take the medication with milk to enhance absorption
• B. Expect stools to be dark in color
• C. Take the medication before bedtime
• D. Avoid foods high in vitamin C

Correct answer: B

Rationale: The correct answer is B: 'Expect stools to be dark in color.' Dark stools are a common side effect of iron supplementation due to the unabsorbed iron, and this is not a cause for concern. Choice A is incorrect because taking iron with milk can decrease its absorption due to calcium binding. Choice C is incorrect as there are no specific recommendations to take ferrous sulfate before bedtime. Choice D is also incorrect as vitamin C actually enhances iron absorption and should not be avoided.

4. A hospitalized toddler who is recovering from a sickle cell crisis holds a toy and says, 'Mine.' According to Erikson's theory of psychosocial development, this child's behavior is a demonstration of which developmental stage?

• A. Autonomy vs. Shame and Doubt
• B. Industry vs. Inferiority
• C. Initiative vs. Guilt
• D. Trust vs. Mistrust

Correct answer: A

Rationale: The toddler's behavior of asserting possession ('Mine') reflects a desire for independence, aligning with Erikson's stage of Autonomy vs. Shame and Doubt. This stage, typical for toddlers aged 1-3 years, focuses on developing a sense of control and independence. Choices B, C, and D are incorrect: Industry vs. Inferiority relates to middle childhood, Initiative vs. Guilt pertains to preschoolers, and Trust vs. Mistrust is associated with infancy.

5. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.
