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 returns from surgery after having a colon resection. The nurse is performing an assessment and notes the wound edges have separated. This condition is called:

• A. Evisceration
• B. Hematoma
• C. Dehiscence
• D. Granulation

Correct answer: C

Rationale: Wound dehiscence occurs when the edges of a wound pull apart. The condition may occur following a surgical procedure if the sutures were deficient. Wound dehiscence may also occur following a wound infection or in cases where a client significantly stretches or overuses the associated tissues. Evisceration refers to the protrusion of internal organs through an open wound. Hematoma is a localized collection of blood outside the blood vessels. Granulation is the formation of new connective tissue and tiny blood vessels on the surface of a wound during the healing process.

3. What kind of preventive measures is MOST likely to be used to prevent Mary Eden from falling due to her muscular frailty?

• A. Physical therapy for muscle strengthening exercises
• B. Physical therapy for range of motion exercises
• C. Occupational therapy to help her with confusion
• D. Medications to help her sleep more

Correct answer: A

Rationale: Mary Eden, due to her muscular frailty, is at risk of falling. The most effective preventive measure in this case would be physical therapy focusing on muscle strengthening exercises. Strengthening exercises can help improve her muscle tone and stability, reducing the risk of falls. While range of motion exercises may be beneficial, they may not directly address her muscular frailty and stability concerns as effectively as muscle strengthening exercises. Occupational therapy aims to help individuals with activities of daily living and functional tasks, not confusion. Medications to induce more sleep can actually increase the risk of falls due to potential side effects like dizziness or disorientation, rather than preventing falls.

4. A nurse is required to float to another unit within the hospital where he is asked to care for a client on a ventilator. The nurse is uncomfortable with this assignment, as he has not had a ventilated client since nursing school. What is the nurse's most appropriate response?

• A. Explain to the nursing supervisor the level of discomfort and ask for a different assignment
• B. State that the client's needs are outside the nurse's scope of practice and request a different assignment
• C. Accept the assignment, asking for help when necessary
• D. Request to return to the home unit and send another nurse who can perform the job

Correct answer: A

Rationale: When floating to another unit and asked to take an assignment that falls outside a nurse's comfort zone, the nurse should notify the area supervisor of the level of discomfort and request a different assignment. Caring for ventilated clients typically falls within the scope of nursing practice; however, discomfort with the situation may not necessarily be overcome by accepting the assignment. Alternatively, the effects could be harmful to the client if the nurse is unfamiliar with this type of care. Requesting a different assignment is the most appropriate response in this situation, ensuring patient safety and the nurse's comfort level. Stating that the client's needs are outside the nurse's scope of practice (Choice B) may not be accurate, as caring for ventilated clients usually falls within the scope of nursing practice. Accepting the assignment (Choice C) without addressing the discomfort may compromise patient safety. Requesting to return to the home unit (Choice D) does not address the immediate need of caring for the ventilated client and may delay appropriate care.

5. Mrs. O is seen for follow-up after an episode of acute pancreatitis. Her physician orders a serum amylase level and the result is 200 U/L. Which of the following is a potential cause of this result?

• A. The client is pregnant
• B. The client has hypertension
• C. The client is in renal failure
• D. The client has pancreatitis

Correct answer: D

Rationale: An elevated serum amylase level after pancreatitis may indicate another attack of the condition. It is common to order serum amylase as part of routine follow-up after pancreatitis. Elevated levels can also be seen in related gastrointestinal conditions like cholecystitis or an intestinal blockage. Therefore, in this case, the most likely cause of the elevated serum amylase level is a recurrence or ongoing pancreatitis. The other options, including pregnancy, hypertension, and renal failure, are not typically associated with an elevated serum amylase level in the context of follow-up after acute pancreatitis.
