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. Albert B. is incontinent of urine. He also wears glasses and hearing aids. His ____________lead(s) to his risk for falls.

• A. incontinence and loss of vision
• B. loss of vision
• C. incontinence
• D. loss of hearing

Correct answer: B

Rationale: Albert B. is at risk for falls due to two factors: his incontinence and his loss of vision. Loss of vision significantly impairs one's ability to navigate and avoid obstacles, thereby increasing the risk of falls. While incontinence is a risk factor for falls, the primary concern in this case is the loss of vision since it directly affects balance and safety. Therefore, the correct answer is 'loss of vision.' Choices A, C, and D are incorrect because they do not address the key factor of impaired vision leading to the risk of falls.

3. A nurse is caring for a dying client whose family wants to be with him in the operating suite. The surgeon, however, does not allow families to be present during surgery. The nurse recognizes this as an ethical dilemma. What is the initial step of the nurse when managing this situation?

• A. Contact the physician to amend the order for the client
• B. Document an account of the situation to ensure adequate coverage of details
• C. Consult with the medical ethics committee to determine a safe and workable solution
• D. Speak with the chief nursing officer to change the policy governing this situation

Correct answer: A

Rationale: In this type of situation, the first action of the nurse should be to address the immediate needs of the client by requesting the physician to make a change based on the circumstances. The primary concern is to ensure the client's well-being and honor the family's wishes, even if it means deviating from standard protocols. While documentation (Choice B) and consulting with higher authorities like the medical ethics committee (Choice C) may be necessary at a later stage, the initial step is to take action to meet the client's needs promptly. Speaking with the chief nursing officer to change the policy (Choice D) is not the most immediate or practical step in this situation, as the focus should be on the client's current care needs.

4. A client is admitted with the diagnosis of pulmonary embolism. While taking a history, the client tells the nurse he was admitted for the same thing twice before, the last time just 3 months ago. The nurse would anticipate the healthcare provider ordering:

• A. Pulmonary embolectomy
• B. Vena caval interruption
• C. Increasing the coumadin therapy to achieve an INR of 3-4
• D. Thrombolytic therapy

Correct answer: B

Rationale: In the case of a client with a history of recurrent pulmonary embolism or contraindications to heparin, vena caval interruption may be necessary. Vena caval interruption involves placing a filter device in the inferior vena cava to prevent clots from traveling to the pulmonary circulation. Pulmonary embolectomy is a surgical procedure to remove a clot from the pulmonary artery, which is usually considered in severe or life-threatening cases. Increasing coumadin therapy to achieve a higher INR may be an option but vena caval interruption would be more appropriate in this scenario. Thrombolytic therapy is used in acute cases of pulmonary embolism to dissolve the clot rapidly, but in a recurrent case with contraindications to anticoagulants, vena caval interruption would be a preferred intervention.

5. The client is receiving an MAOI. Which foods should the nurse caution the client to avoid?

• A. Pork, spinach, and fresh oysters
• B. Milk, grapes, and meat tenderizers
• C. Cheese, beer, and products with chocolate
• D. Leafy green vegetables, fresh apples, and ice cream

Correct answer: C

Rationale: The correct answer is C. When a client is receiving a monoamine oxidase inhibitor (MAOI), they should avoid foods high in tyramine to prevent a hypertensive crisis. Cheese, beer, and products with chocolate are rich in tyramine and can interact with MAOIs, leading to a dangerous rise in blood pressure. Choices A, B, and D do not contain high levels of tyramine and are not typically restricted when taking MAOIs.
