LCAS content outline and where to practise each area

The content areas below are copied from the official LCAS content outline published by North Carolina Addictions Specialist Professional Practice Board (NCASPPB). The exam is the IC&RC Advanced Alcohol and D, with the share of the exam each area carries. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through LCAS questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: How should patient consent be obtained for documentation standards procedures?

1. Verbal agreement is always sufficient
2. Informed consent including risks, benefits, alternatives, and right to refuse
3. Consent is implied by the patient's presence
4. Family consent overrides patient consent

Answer: B. Informed consent including risks, benefits, alternatives, and right to refuse

Explanation:

B is correct. Valid informed consent means the client understands the risks, benefits and alternatives, and knows they can say no. That is what protects the client's right to decide.

A is wrong because a simple verbal yes does not show the client understood what they agreed to. The word "always" is also a warning sign. C is wrong because showing up for an appointment is not agreement to a specific procedure. D is wrong because a capable adult client's own decision is not overridden by family members.

Rule to remember: consent belongs to the client and has to be informed. If an option uses absolute words or takes the decision away from the client, it is usually wrong.

Example 2

Question: Which of the following correctly describes the primary mechanism of action of opioids in the central nervous system?

1. They block dopamine reuptake in the nucleus accumbens
2. They bind to mu, kappa, and delta opioid receptors
3. They enhance GABA-A receptor chloride conductance
4. They antagonize NMDA glutamate receptors

Answer: B. They bind to mu, kappa, and delta opioid receptors

Explanation:

B is correct. Opioids act by binding to the mu, kappa and delta opioid receptors in the brain and body. Mu receptors are the main source of their pain relief, euphoria and risk of respiratory depression.

A is wrong because blocking dopamine reuptake is how stimulants such as cocaine work. C is wrong because increasing GABA-A chloride conductance describes benzodiazepines, barbiturates and alcohol. D is wrong because NMDA antagonism describes drugs such as ketamine and PCP.

Rule to remember: match each drug class to its main target. Opioids act on opioid receptors, stimulants on dopamine, depressants on GABA and dissociatives on NMDA. Questions often use the other classes' mechanisms as the wrong answers.

Example 3

Question: What is the primary purpose of involving the client in the treatment planning process?

1. To save time for the clinician
2. To ensure the client adheres to the plan
3. To promote client autonomy and engagement
4. To standardize the treatment approach

Answer: C. To promote client autonomy and engagement

Explanation:

C is correct. Involving clients in planning respects their right to make their own decisions. A plan built around the client's own goals is one they are more likely to own and stay engaged with.

A is wrong because collaboration usually takes more of the clinician's time, not less, and saving time is never the purpose. B is tempting because adherence often does improve. But that is a result of engagement, not the main reason for involving the client, and "ensure" overstates what any clinician can control. D is wrong because client involvement makes a plan more individual, not more standardized.

Rule to remember: when an answer puts client autonomy and self-determination first, it usually beats answers about clinician convenience or control.

How to use these practice tests

Start by downloading the IC&RC AADC candidate guide and reading the content outline. Use the domain weights to plan your time. Counseling and Education carries 30%, and the other domains carry 23% to 24% each, so give counseling a little more time without skipping anything.

Take a short set from each practice area above before you study. This shows you where you are weakest. Then work through the matching set for each domain: assessment for Domain I, treatment planning for Domain II, treatment modalities and crisis intervention for Domain III, and ethics and confidentiality for Domain IV. Add the pharmacology and co-occurring disorders sets, since those topics come up across several domains.

For every question you miss, write down why the right answer is right and why your choice was wrong, as in the worked examples above. Repeat a set only after you have reviewed it.

As test day gets closer, sit a longer mixed session in one go. Pace yourself so that 150 questions fit inside 3 hours, and mark slow questions to come back to. Before you book, check the NCASPPB exam information page and fee schedule again. Remember that a retake means a wait of at least 90 days.
