Sample Question 1

A 45-year-old woman is newly diagnosed with type 2 diabetes mellitus. Her initial evaluation shows: BP 128/72 mmHg, BMI 33 kg/m², A1c 8.7%, eGFR >60 mL/min/1.73m², and urine albumin-to-creatinine ratio (UACR) 18 mg/g. She has no established ASCVD, heart failure, or chronic kidney disease. What is the most appropriate initial pharmacologic treatment?

Metformin

Metformin and lifestyle changes

Metformin and dulaglutide (Trulicity)

Metformin and pioglitazone

Answer: B. Metformin and lifestyle changes

Rationale:

Metformin is the preferred first-line pharmacologic therapy for type 2 diabetes unless contraindicated, and it should be combined with lifestyle modifications (nutrition, exercise, and weight management). Combination therapy can be considered when A1c is ≥1.5–2% above goal, but the first step remains metformin monotherapy with concurrent lifestyle changes for most patients without cardiorenal comorbidities.
Metformin monotherapy alone without structured lifestyle modification is suboptimal; lifestyle change is an essential part of initial management.
Dulaglutide (Trulicity) — While GLP-1 receptor agonists are appropriate add-ons, they are not indicated as *initial therapy* in a patient without ASCVD, CKD, or heart failure. Early combination therapy may be considered for rapid A1c reduction but is not required in this scenario.
Pioglitazone may cause weight gain and edema and is not recommended as first-line therapy, especially in an obese patient.

High-Yield Core Concept

Metformin with lifestyle modification is the standard first-line therapy for most patients with type 2 diabetes unless specific comorbidities warrant initial use of agents with cardiorenal benefit (GLP-1 RA or SGLT2 inhibitor).

High-Yield Fast Fact

Consider early combination therapy only if A1c is ≥9% or ≥1.5–2% above individualized target, or if rapid glycemic control is needed.

Sample Question 2

A 56-year-old female presents to your clinic with the following fasting laboratory test results: total cholesterol 218 mg/dL, triglycerides 153 mg/dL, HDL 51 mg/dL, LDL 139 mg/dL, and A1c 5.9%. She does not take any prescription medications. She follows a heart healthy diet, does not use tobacco products and does not drink alcohol. Her atherosclerotic cardiovascular disease (ASCVD) risk score is 2.3%. Her liver and kidney function are within normal limits. Which of the following is the best recommendation for this patient?

Start fish oil

Start atorvastatin 40 mg daily

Start rosuvastatin 5 mg daily

Initiate lifestyle changes to reduce risk factors

Answer: D

Rationale:

The fourth answer choice is correct because this patient has a low 10-year ASCVD risk score at <5%. At this point, it is important to emphasize lifestyle changes to help reduce risk factors. A diet rich in vegetables, legume, nuts, whole grains and fish is recommended with minimized intake of refined carbohydrates and sweetened beverages. Adults should engage in at least 150 minutes a week of moderate-intensity, or 75 minutes a week of vigorous-intensity aerobic physical activity.
The first answer choice is not necessary because this patient does not have elevated triglycerides > 500 mg/dL to warrant fish oil therapy.
The second answer choice is not appropriate because atorvastatin 40 mg daily is a high intensity statin and this patient has a low ASCVD risk score. A high intensity statin would be appropriate if her ASCVD risk score was ≥ 20%.
The third answer choice is incorrect because a moderate intensity statin such as rosuvastatin 5 mg daily can be considered when the ASCVD risk score is between 5% to 20%.

High-Yield Core Concept:

For adults age 40-75 and LDL-C of 70–189 mg/dL without diabetes, a 10-year ASCVD risk score is needed to determine therapy. If the 10-year ASCVD risk is > 5% with risk enhancers present, risk discussion regarding moderate intensity statin therapy is appropriate. If the 10-year ASCVD risk is > 20%, initiate high intensity statin therapy to reduce the LDL-C by > 50%.

High-Yield Fast Fact(s):

Examples of ASCVD risk enhancers include: family history of premature ASCVD, elevated LDL-C >160 mg/dL, chronic kidney disease, metabolic syndrome, pre-eclampsia, premature menopause and inflammatory disease (rheumatoid arthritis, psoriasis, HIV/AIDS) and South Asian ethnicity.

Sample Question 3

A study was completed and revealed a p-value between the two treatment groups to be p = 0.01. Assuming an alpha = 0.05, which of the following offers the best interpretation of this p-value?

There is a 5% chance the study has made a type II error

There is a 1% chance that the study results are due to random error

There is a 5% chance that the study results are due to chance alone

There is a 0.01% chance that the results are due to chance alone

Answer: B

Rationale:

This is a high-yield concept that you must know.
A p-value only helps you to know whether the results that were found in the study were due to random error or due to chance alone.
In order to interpret this p-value fully you have to convert it into a percentage. To do this all you have to do is multiple it by 100 or move the decimal point over to the right by two spaces. Therefore, the p-value of 0.01 is the same as 1%. Therefore, based on the definition of a p-value above, there is a 1% chance that the study results are due to random error or chance.
The alpha value is the level or chance an investigator could be making a type I error. As a reminder, a type I error occurs when the study or investigators say there is a difference between two studied interventions, but in reality, there is actually no difference at all. Its use in this case is simply basic information and not meant to be something to focus on.

High-Yield Core Concept:

A p-value does not determine if the results are clinically significant, but rather if the results are due to random error or due to chance alone. A study attempts to measure the truth and reduce bias and random error since we are only studying a sample from the entire general population.

High-Yield Fast Fact:

The most accepted cut-off value for determining when to accept or reject the null hypothesis is about 0.05, which corresponds to 2 standard deviations from the mean.
