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. When a blood pressure cuff is too wide for a client's arm, what type of reading might this blood pressure cuff produce?

• A. A normal reading
• B. An abnormally low reading
• C. An abnormally high reading
• D. A fluctuating reading

Correct answer: B

Rationale: When a blood pressure cuff is too wide for a client's arm, it may produce an abnormally low blood pressure reading. This occurs because the oversized cuff can lead to an underestimation of blood pressure. It is essential to ensure that the cuff fits appropriately to obtain an accurate reading. An abnormally high reading (Choice C) is less likely with an oversized cuff, as it generally leads to lower readings. A normal reading (Choice A) is unlikely due to the inaccuracies caused by the oversized cuff. A fluctuating reading (Choice D) is not a typical result of using a cuff that is too wide; instead, it usually leads to consistently low readings.

3. The discharge planning team is discussing plans for the dismissal of a 16-year-old admitted for complications associated with asthma. The client's mother has not participated in any of the discharge planning processes but has stated that she wants to be involved. Which of the following reasons might prohibit this mother from participating in discharge planning?

• A. The client is an emancipated minor
• B. The mother has to work and is unavailable
• C. The client has a job and a driver's license
• D. The mother does not speak English

Correct answer: A

Rationale: In this scenario, the correct answer is that the client is an emancipated minor. Emancipated minors, even if they are under the age of 18, have the legal right to make decisions about their own healthcare and planning, which may include not wanting their parent involved in the discharge planning process. This status grants them independence from parental involvement in certain situations. The other choices are incorrect because the mother's work schedule, the client's job and possession of a driver's license, and the mother's language proficiency do not inherently prevent her from participating in the discharge planning process, unlike the legal status of being an emancipated minor.

4. All hospitals and nursing homes are mandated to have the goal of a restraint-free environment. The best way to achieve this goal is to ________________.

• A. ban the use of all restraints under all circumstances
• B. limit restraints to only those situations when falls cannot be prevented
• C. keep all bedside rails up for all patients during nighttime hours
• D. use non-skid socks and sheets to prevent falls from chairs

Correct answer: B

Rationale: All hospitals and nursing homes are mandated by JCAHO and state departments of health to have the goal of a restraint-free environment. This does not mean that no restraints can ever be used under any circumstances. The goal is to minimize the use of restraints and prioritize other preventive measures. Restraining a patient should only be considered when all other preventive strategies have failed, and the patient is at risk of harm. Therefore, the best approach is to limit the use of restraints to situations where falls cannot be prevented, ensuring that restraints are used as a last resort to maintain patient safety. Choices C and D are not ideal solutions as they do not address the appropriate use of restraints in a restraint-free environment.

5. A healthcare professional is preparing to draw a blood specimen from an adult client's central line. All of the following actions for this procedure are correct EXCEPT:

• A. Disconnect the current infusion
• B. Clean the cap with alcohol and attach a 5 cc syringe
• C. Draw 5 cc of a blood sample to discard
• D. Flush with saline after the sample

Correct answer: B

Rationale: When drawing a blood specimen from a central line, the healthcare professional should disconnect any infusions that are currently running and that could contaminate the specimen. It is important to use a minimum size of a 10 cc syringe when using a central line to avoid placing too much pressure on the catheter. Cleaning the cap with alcohol and attaching a 5 cc syringe is not appropriate as a larger syringe size should be used for this procedure. Drawing 5 cc of a blood sample to discard and flushing with saline after the sample are correct steps in the process of drawing a blood specimen from a central line.
