Nursing Elites

1. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

• A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
• B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
• C. The client should lie flat on their back for a specific period following the procedure.
• D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

2. A client needs to give informed consent for electroconvulsive therapy treatments. Which of the following actions should the nurse take?

• A. Explain the adverse effects the client might experience from the treatment
• B. Verify the client gave consent voluntarily for the treatment
• C. Describe the benefits of the treatment to the client
• D. Outline possible alternatives to the treatment for the client

Correct answer: B

Rationale: When obtaining informed consent for a procedure like electroconvulsive therapy, the nurse's primary responsibility is to ensure that the client has given consent voluntarily and is capable of making such a decision. While it is essential to provide information on the treatment's benefits, risks, and alternatives, the priority is to verify the client's voluntary consent. Explaining the adverse effects and describing the benefits are important steps in the informed consent process, but the critical step is to confirm the client's voluntary agreement. Outlining possible alternatives to the treatment is also important but comes after ensuring the client's voluntary consent.

3. When teaching a client with coronary artery disease about nutrition, what should the nurse emphasize?

• A. Eating three balanced meals a day
• B. Adding complex carbohydrates
• C. Avoiding very heavy meals
• D. Limiting sodium intake to 7 g per day

Correct answer: C

Rationale: The correct answer is to emphasize avoiding very heavy meals. Eating large, heavy meals can divert blood away from the heart for digestion, potentially endangering clients with coronary artery disease. This practice may lead to an increased risk of plaque accumulation in the arteries, potentially obstructing the delivery of blood and oxygen to vital organs. Choices A, B, and D are incorrect. While eating three balanced meals a day, adding complex carbohydrates, and limiting sodium intake are generally good dietary practices, they are not the primary focus when teaching a client with coronary artery disease about nutrition. The emphasis should be on avoiding heavy meals that can strain the cardiovascular system.

4. Which example best describes the concept of beneficence?

• A. A nurse provides pain medication for a client in the recovery room who is experiencing pain
• B. A client has an advanced directive in place stating that he does not want intubation if he needs CPR
• C. At the request of the client, a nurse does not inform the family about his cancer diagnosis
• D. A nurse withholds narcotic medication for a client in pain, knowing that he is currently disoriented

Correct answer: A

Rationale: Beneficence is the ethical principle of doing good and acting in the best interest of the client. Providing pain relief to a client in the recovery room who is experiencing pain aligns with beneficence as it promotes the client's well-being and comfort. Choice B is related to autonomy, where the client's wishes regarding treatment are respected. Choice C involves confidentiality and the client's right to privacy. Choice D represents nonmaleficence, as withholding pain medication from a client in pain could cause harm and goes against the principle of doing no harm.

5. Mr. G has been admitted to the hospital with a head injury after a 12-foot fall. Which of the following nursing interventions is most appropriate when monitoring intracranial pressure?

• A. Administer hypotonic solutions
• B. Keep the head of the bed elevated
• C. Increase the client's core body temperature to 99.9 degrees
• D. Administer corticosteroids as ordered

Correct answer: D

Rationale: Administering corticosteroids as ordered is appropriate when monitoring intracranial pressure in clients at risk of increased pressure to reduce brain tissue swelling. Elevating the head of the bed helps in managing intracranial pressure by promoting venous drainage. Administering hypertonic solutions is used to reduce brain edema and control intracranial pressure. Increasing the client's core body temperature is not recommended as it can exacerbate brain injury. Corticosteroids are not routinely used for all head injuries but may be indicated in specific cases, such as certain types of brain injuries where swelling needs to be controlled.
