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 with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?

• A. Peaked T waves on the ECG
• B. Muscle spasms
• C. Constipation
• D. A prominent U wave on the ECG

Correct answer: A

Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.

3. Which of the following types of antipsychotic medications is most likely to produce extrapyramidal effects?

• A. Atypical antipsychotic drugs
• B. First-generation antipsychotic drugs
• C. Third-generation antipsychotic drugs
• D. Dopamine system stabilizers

Correct answer: B

Rationale: The correct answer is first-generation antipsychotic drugs. These drugs are potent antagonists of D2, D3, and D4 receptors, making them effective in treating target symptoms but also leading to numerous extrapyramidal side effects due to the blockade of D2 receptors. Atypical or second-generation antipsychotic drugs, as mentioned in choice A, are relatively weak D2 blockers, which results in a lower incidence of extrapyramidal side effects. Third-generation antipsychotic drugs, as in choice C, and dopamine system stabilizers, as in choice D, are not typically associated with significant extrapyramidal effects compared to first-generation antipsychotics.

4. A patient with Addison's disease asks a nurse for nutrition and diet advice. Which of the following diet modifications is not recommended?

• A. A diet high in grains
• B. A diet with adequate caloric intake
• C. A high protein diet
• D. A restricted sodium diet

Correct answer: D

Rationale: For a patient with Addison's disease, a restricted sodium diet is not recommended. These patients require normal dietary sodium to prevent excess fluid loss. Patients with primary adrenal insufficiency (Addison disease) should have ample access to salt because of the salt wasting that occurs if their condition is untreated. Therefore, a diet high in grains, a diet with adequate caloric intake, and a high protein diet are all recommended for patients with Addison's disease to support their nutritional needs and overall health. However, restricting sodium can be detrimental for these patients due to the nature of their condition.

5. You are on the unit and overhear another nurse talking on the phone to a patient's friend who wants to see her patient who is comatose and on a ventilator. Since you cared for that patient yesterday, you know that the patient's significant other, who is also the designated healthcare surrogate (HCS) and has power of attorney (POA), has expressly stated that he wants this person on the list for restricted visitors. The nurse whispers that she'll call him to visit as soon as the significant other has gone home. What should your first response be?

• A. Inform the significant other
• B. Report the nurse to the nurse manager
• C. Speak with the nurse directly in private
• D. Call the visitor and tell him he can't visit

Correct answer: C

Rationale: Speaking with the nurse directly and privately is the most constructive manner in which to handle this situation and advocate for the significant other's wishes. Doing so will open communication with a peer and build the relationship, instead of alienating the other nurse by taking action that does not involve her and will cast her in a negative light with others. It is essential to express your concerns regarding honoring the significant other's requests and rights regarding the limitation of visitors. Option A is incorrect because the significant other is not the one trying to visit, and it is more appropriate to address the nurse directly first. Option B is not the best initial response as it may escalate the situation without giving the nurse a chance to correct the issue. Option D is incorrect as it does not address the issue at its source and may create further conflict without resolving the underlying problem.
