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 is receiving education on cholesterol. Which of the following statements from the client indicates the need for further teaching?

• A. I would like my HDL levels to be over 50.
• B. It is better for me to have high HDL levels and low LDL levels.
• C. It is better for me to have high LDL levels and low HDL levels.
• D. My goal is to get my total cholesterol below 200.

Correct answer: C

Rationale: The correct answer is, 'It is better for me to have high LDL levels and low HDL levels.' This statement indicates a need for further teaching because high LDL levels contribute to atherosclerosis, while high HDL levels can protect against heart disease. The client should understand the importance of lowering LDL levels and increasing HDL levels to maintain good heart health. Choice A is correct as desiring HDL levels over 50 is a positive goal. Choice B is correct as it reflects the ideal scenario of high HDL and low LDL levels. Choice D is correct as a total cholesterol below 200 is a common goal for heart health. Therefore, Choice C is incorrect as it suggests an opposite and unhealthy relationship between LDL and HDL levels.

3. A client is preparing to give a stool sample for occult blood. All of the following information is part of teaching for this client EXCEPT:

• A. Avoid eating red meat for 3 days before the test
• B. Collect the stool sample from the toilet after having a bowel movement
• C. The stool does not need to be kept in a container with preservative
• D. A small part of the stool from two areas will be tested using a smear

Correct answer: B

Rationale: When preparing to give a stool sample for occult blood testing, clients need specific instructions to ensure accurate results. It is crucial to educate clients to avoid eating red meat for at least 3 days before the test, as the blood in the meat can interfere with the test results. Clients should be informed that the stool does not need to be kept in a container with preservative as it is not required for this type of testing. Additionally, clients should be aware that a small part of the stool from two areas will be tested using a smear. However, collecting the stool sample from the toilet after having a bowel movement is not recommended as it may introduce contaminants and affect the accuracy of the test. Therefore, this information is not part of the correct teaching for the client preparing to give a stool sample for occult blood.

4. 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.

5. The nurse teaches a patient about the transmission of pulmonary tuberculosis (TB). Which statement, if made by the patient, indicates that teaching was effective?

• A. I will avoid being outdoors whenever possible.
• B. My husband will be sleeping in the guest bedroom.
• C. I will take the bus instead of driving to visit my friends.
• D. I will keep the windows closed at home to contain the germs.

Correct answer: B

Rationale: To prevent the transmission of pulmonary tuberculosis, it is important for the infected individual to minimize exposure to close contacts and household members. Sleeping alone in a separate room, like the guest bedroom, is an effective measure. The other choices are not ideal: Choice A is incorrect because spending time outdoors is encouraged for ventilation; Choice C is incorrect as using public transportation increases the risk of transmission; Choice D is incorrect because keeping windows closed limits ventilation, which is necessary to reduce the concentration of infectious particles in the air.
