Nursing Elites

1. Which of the following interventions is necessary before insertion of an arterial line into the radial artery?

• A. Ensure that the client does not need surgery
• B. Assess the client's grip strength
• C. Perform an Allen test
• D. Check a serum potassium level

Correct answer: C

Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line. Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.

2. A physician has written an order for '2.0 mg MS q 2-4 hr prn pain.' What is the nurse's appropriate response to this order?

• A. Give 2 mg of morphine sulfate to the client
• B. Give 20 mg of morphine sulfate to the client
• C. Contact the pharmacy to clarify the order
• D. Contact the physician to rewrite the order

Correct answer: D

Rationale: The physician's order contains several errors that could lead to potential harm to the client if not addressed. The use of '2.0' involves a trailing decimal point, which may lead to confusion regarding the intended dose of the drug. Additionally, the abbreviation 'MS' is considered a Do Not Use abbreviation by the Joint Commission, as it could refer to morphine sulfate or magnesium sulfate, leading to medication errors. While the order indicates the drug should be used for pain, the nurse should contact the physician to clarify the exact dose and specific drug to be administered, ensuring safe and accurate medication administration. Therefore, the correct response is to contact the physician to rewrite the order.

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 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.

5. Which nursing intervention is most appropriate to maintain the patency of a client's nasogastric tube?

• A. Maintain a constant connection to low-intermittent suction
• B. Irrigate the tube as per physician's order
• C. Suction the mouth and nose every shift
• D. Perform a daily fecal occult blood sample

Correct answer: B

Rationale: The correct answer is to irrigate the tube as per physician's order. A client with a nasogastric tube is at risk of the tube kinking or clotting off, which can lead to complications such as abdominal distention or vomiting. To ensure the patency of the tube, the nurse should follow the physician's orders and facility policy to irrigate the tube with water or a solution as needed. Maintaining a constant connection to low-intermittent suction (Choice A) is not typically done to maintain tube patency. Suctioning the mouth and nose every shift (Choice C) is not directly related to maintaining nasogastric tube patency. Performing a daily fecal occult blood sample (Choice D) is unrelated to maintaining the patency of a nasogastric tube.
