NCLEX RN Practice Questions With Rationale

1. In which of the following examples would informed consent not be required?

A. A patient is apprehensive about an upcoming surgery and chooses not to learn of the risks involved with the procedure.
B. A child is rushed to the Emergency Room after falling from a third-story window.
C. An adult in a coma in a mental health institution with no listed next of kin.
D. Informed consent is not required in any of the above examples.

Correct answer: D

Rationale: In emergency situations where immediate treatment is necessary to prevent further harm or save a life, such as in option B where a child is rushed to the Emergency Room after a fall, informed consent may be waived to provide prompt care. In option A, though the patient is apprehensive about surgery and chooses not to learn the risks, informed consent is not required as it is the patient's right to refuse information. In option C, when an adult is in a coma with no next of kin listed, decisions may be made in the patient's best interest following legal and ethical guidelines. Therefore, informed consent is not needed in any of the scenarios presented.

2. 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.

3. 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.

4. Victor, a 43-year-old patient who is HIV positive with a diagnosis of pneumocystis carinii pneumonia (PCP), has been admitted to the hospital. His prognosis is very poor, and his partner, Roger, would like to have a ceremony performed in his room to honor their union in case something happens to Victor, who agrees. What is the most appropriate response to their request?

A. Inform them that Victor is too ill for a ceremony
B. Ask the social worker to intervene
C. Tell them it's against hospital policy
D. Coordinate with other disciplines to support their request

Correct answer: D

Rationale: The most appropriate and compassionate response is to respect Victor and Roger's relationship and honor their wishes. Coordinating with other disciplines, such as social work, chaplaincy, or patient advocacy, to support their request demonstrates a holistic approach to care. This collaborative effort can facilitate the ceremony and provide emotional support to both Victor and Roger during a challenging time. Upholding their request aligns with the principles of patient-centered care and promotes dignity and respect, as outlined in the ANA Code of Ethics. Informing them that Victor is too ill for a ceremony (Choice A) would dismiss their emotional needs and fail to address their request. Involving the social worker without understanding the specific request (Choice B) may not directly address their desire for a ceremony. Telling them it's against hospital policy (Choice C) disregards the importance of honoring patient preferences and may cause unnecessary distress in an already sensitive situation.

5. A patient diagnosed with a mild anxiety disorder has been referred to treatment in a community mental health center. Treatment most likely provided by the center includes

A. Medical management of symptoms
B. Daily psychotherapy
C. Constant staff supervision
D. Psychological stabilization

Correct answer: A

Rationale: Community mental health centers focus on rehabilitation, vocational needs, education, and socialization, as well as on the management of symptoms and medication. For a patient with a mild anxiety disorder, the primary focus would be on providing medical management of symptoms, such as prescribing appropriate medications and monitoring their effectiveness. Daily psychotherapy is not typically provided in community mental health centers for mild cases, as it may not be necessary. Constant staff supervision and psychological stabilization are more suited for patients requiring a higher level of care or in acute settings where continuous monitoring and stabilization are essential.
