Health Promotion and Maintenance NCLEX RN Questions

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. What is involved in obtaining informed consent?

A. An explanation of the reasons for the procedure
B. A signature on a form indicating the client agrees to the procedure
C. A statement affirming liability if complications arise during the procedure
D. Both A and C

Correct answer: A

Rationale: Informed consent involves providing the client with an explanation of the reasons for the procedure, the potential risks, benefits, and available alternatives. It is essential for the healthcare provider to ensure that the client understands the information provided before agreeing to the procedure. While obtaining a signature on a consent form is part of the process, it is not the sole indicator of informed consent. Option C, which mentions liability statements, is incorrect as informed consent focuses on ensuring the client understands the procedure, not on affirming liability. Therefore, the correct answer is the explanation of the reasons for the procedure.

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. What does the 'B' in the SBAR acronym stand for?

A. Background
B. Basic
C. Beginning
D. Break

Correct answer: A

Rationale: The 'B' in the SBAR acronym stands for Background. SBAR is a standardized communication tool used in healthcare to effectively communicate critical information. In this context, 'Background' refers to providing relevant information about the patient's history, current status, and any other pertinent details. This information helps ensure clear and concise communication between healthcare providers, enhancing patient care. Choice B, 'Basic,' is incorrect as the 'B' specifically emphasizes the detailed background information. Choices C and D, 'Beginning' and 'Break,' are not accurate in the context of the SBAR communication tool.

5. Which of the following is a local sign of infection?

A. Swelling
B. Rapid pulse
C. Fever
D. High white blood count

Correct answer: A

Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.
