Nursing Elites

1. A nurse is reviewing the medical record of a client who has chronic kidney disease. The client's potassium level is 6.5 mEq/L. Which of the following actions should the nurse take?

• A. Administer sodium bicarbonate
• B. Administer sodium polystyrene sulfonate
• C. Administer calcium gluconate
• D. Administer calcium carbonate

Correct answer: B

Rationale: The correct answer is B: Administer sodium polystyrene sulfonate. Sodium polystyrene sulfonate is used to treat hyperkalemia by promoting the excretion of potassium. Choice A, administering sodium bicarbonate, is incorrect as it is not used to treat hyperkalemia. Choice C, administering calcium gluconate, is incorrect as it is used to treat hypocalcemia, not hyperkalemia. Choice D, administering calcium carbonate, is incorrect as it is used to treat conditions like osteoporosis and indigestion, not hyperkalemia.

2. A nurse in a mental health facility is caring for a client who is angry and throwing objects at staff members. Which of the following actions should the nurse take?

• A. Ask the client to identify what made them angry.
• B. Instruct the client to calm down.
• C. Place the client in seclusion.
• D. Encourage the client to attend group therapy.

Correct answer: C

Rationale: During a situation where a client is exhibiting violent behavior like throwing objects and posing a risk to themselves and others, the immediate priority is to ensure the safety of all involved. Placing the client in seclusion is a necessary intervention to prevent harm and allow for de-escalation. Asking the client to identify the trigger or instructing them to calm down may not be effective or safe in this escalated state. Encouraging the client to attend group therapy is not suitable when they are in an agitated and aggressive state that requires immediate intervention.

3. A healthcare professional is preparing to administer digoxin to a client with heart failure. Which of the following laboratory values should the professional report to the provider?

• A. Potassium 4.0 mEq/L
• B. Calcium 9.5 mg/dL
• C. Sodium 140 mEq/L
• D. Magnesium 2.0 mg/dL

Correct answer: C

Rationale: The correct answer is C: Sodium 140 mEq/L. An elevated sodium level can affect the effectiveness of digoxin therapy and may lead to toxicity. Therefore, it is crucial to report this value to the provider. Potassium, calcium, and magnesium levels are important as well, but elevated sodium can have a more direct impact on digoxin therapy in this scenario.

4. A client is preparing advance directives. Which of the following statements by the client indicates an understanding of advance directives?

• A. I cannot change my instructions once I have signed them.
• B. My doctor will need to approve my advance directives.
• C. I need a witness to sign my advance directives.
• D. I have the right to refuse treatment.

Correct answer: D

Rationale: The correct answer is D: 'I have the right to refuse treatment.' This statement shows an understanding of advance directives because they allow individuals to specify their treatment preferences in advance, including the right to refuse treatment. Choices A, B, and C are incorrect. Choice A is inaccurate as individuals can update or change their advance directives at any time. Choice B is incorrect because while a doctor may discuss advance directives with the client, approval is not required for the directives to be valid. Choice C is also incorrect as a witness is typically required to verify the client's signature, not the other way around.

5. How should a healthcare professional administer a subcutaneous injection?

• A. Insert the needle at a 45-degree angle
• B. Insert the needle at a 90-degree angle
• C. Use a Z-track method
• D. Insert the needle at a 15-degree angle

Correct answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.
