AAPC-CDEO Certified Documentation Expert Outpatient - Set 2 - Part 1

Correct Answer: Congenital cardiomyopathy

NHLBI guidance defines congenital cardiomyopathy as present at birth, and states it may result from a congenital heart defect or from non-inherited health conditions of the mother or the developing baby. Option a is incorrect because acquired means the patient was not born with the disease and developed it later because of another disease or condition that damaged the heart. Option b is incorrect because NHLBI guidance lists it with hypertrophic cardiomyopathy as a form that is often inherited, not as one tied to non-inherited maternal conditions. Option d is incorrect because inherited means parents passed the gene for the disease to the child, so the cause lies in gene mutations rather than non-inherited maternal or fetal conditions.

Correct Answer: Patent ductus arteriosus

Patent ductus arteriosus occurs when the ductus arteriosus, a fetal vessel connecting the pulmonary trunk and aorta and bypassing the pulmonary circulation, fails to close after birth. The scenario matches this definition exactly. Option b is incorrect because it is a hole in the septum between the atria that does not close at birth, not a vessel joining the pulmonary trunk and aorta. Option c is incorrect because it is an opening in the wall between the left and right ventricles, so it involves a septum, not the ductus vessel. Option d is incorrect because it describes a narrowing of the aorta that forces the heart to pump harder, rather than a fetal vessel that stays open.

Correct Answer: Appearance

The Apgar score evaluates a newborn within one to five minutes after birth using the mnemonic APGAR. Appearance, the first criterion, refers to skin color. Option a is incorrect because activity refers to muscle tone in the Apgar mnemonic, so it is evaluated through movement and posture rather than coloring. Option b is incorrect because pulse is the criterion that reflects heart rate, so it is judged by cardiac activity and not by the color of the skin. Option c is incorrect because grimace measures reflex response in the newborn, which is a different element of the five-part mnemonic from the visible skin color.

Correct Answer: Detectable anti-HIV antibodies

The presence of detectable anti-HIV antibodies in a person's blood indicates a positive HIV test, which is referred to as seroconversion. Afterward, circulating virus drops while CD4 T cells slowly decline. Option b is incorrect because CD4 T cells are helper T cells that decline steadily after seroconversion, so a rising count would not signal a positive test. Option c is incorrect because opportunistic infections occur more often or more severely in weakened immune systems, which makes them a consequence of immune decline, not the testing marker. Option d is incorrect because viral levels dropping and staying low for several years describes what follows seroconversion, not the finding that defines the positive result itself.

Correct Answer: T-helper cells

HIV is a virus that attacks the T-helper cells, a type of lymphocyte of the immune system. If HIV is not treated, it can lead to acquired immunodeficiency syndrome (AIDS). Option a is incorrect because red blood cells are not described as the target of HIV; the virus attacks a type of lymphocyte, which is a white blood cell. Option b is incorrect because phagocytes are listed among the components whose failure or absence causes immunodeficiency, but HIV is described as attacking the helper T cells instead. Option d is incorrect because B lymphocytes are not named as the HIV target; the guidance specifies T-helper cells as the lymphocyte type that the virus attacks.

Correct Answer: It is not regulated by the FDA

Herbal and supplement substances, often grouped as complementary and alternative medications (CAM), are not regulated by the FDA. Nurses document them in the record because they can still cause adverse effects or interact with prescribed drugs. Option b is incorrect because prescription medications are the drugs ordered by a licensed prescriber for a specific person and regulated by the FDA, which does not describe herbal products. Option c is incorrect because most herbal and supplement substances have not gone through rigorous scientific testing for safety for the public, so this overstates their evidence. Option d is incorrect because the guidance warns there is no guarantee that herbals or supplements contain the ingredients listed on the label, so this claim contradicts it.

Correct Answer: Bone marrow biopsy

Leukemia is diagnosed with a bone marrow biopsy. The bone marrow is the body's blood-forming tissue, where the abundance of nonfunctional leukocytes originates, so sampling it confirms the disease. Option a is incorrect because it assigns an overall Stage 0 to Stage IV based on tumor size and spread, which makes it a staging tool and not a diagnostic procedure. Option b is incorrect because the guidance lists it with chemotherapy as a possible treatment for leukemia, so it comes after diagnosis and cannot establish it. Option d is incorrect because it is a staging modality that uses tumor size, number of lymph nodes involved and metastasis, so it describes cancer extent rather than diagnosing leukemia.

Correct Answer: Neoadjuvant chemotherapy

Chemotherapy given before surgical resection to shrink the tumor and make it easier to resect is neoadjuvant chemotherapy, also called induction or preoperative chemotherapy. Option a is incorrect because primary treatment means systemic therapy alone is the treatment for the cancer, not a step intended to shrink a tumor before surgery. Option c is incorrect because adjuvant chemotherapy is given after surgical resection to address microscopic disease or reduce recurrence, so its timing is the opposite of this record. Option d is incorrect because palliative use applies when the cancer cannot be eradicated, aiming to control pain and symptoms rather than to prepare a tumor for resection.

Correct Answer: Metastasis

Metastasis is the spread of malignant cells to other parts of the body, typically through the blood or lymphatic system. Malignant cells are the most dangerous because of this ability to invade distant organs and tissues. Option b is incorrect because benign cells divide in a controlled manner and stay localized to one area, so they would not appear in distant organs. Option c is incorrect because it is an immune attack by transplanted bone marrow cells on the recipient's tissues and has nothing to do with tumor cells traveling. Option d is incorrect because it is programmed cell death that regulates cell population, which some cancers disrupt, rather than the movement of cells to distant sites.

Correct Answer: Polycythemia vera

Primary polycythemia is also known as polycythemia vera (PV). It is caused by a type of bone marrow cancer that leads to overproduction of red blood cells, white blood cells and platelets. Option a is incorrect because this is the name for inherited aplastic anemia, which stems from genetic mutations affecting bone marrow production and function. Option b is incorrect because a genetic hemoglobin disorder with sickle-shaped red blood cells and chronic anemia; it is not a form of polycythemia at all. Option c is incorrect because it describes a reduction in all three major blood cell types, so it is a finding of marrow failure rather than excess red cells.

Correct Answer: Anemia

Anemia is a condition with a reduced number of red blood cells, amount of hemoglobin or hematocrit. It lowers oxygen delivered to body tissues and commonly causes fatigue, weakness, shortness of breath, palpitations and pale skin. Option b is incorrect because describes an excessive number of red blood cells with thicker blood and a higher risk of clotting, which is the opposite of a low hemoglobin finding. Option c is incorrect because means blood thicker than normal, which slows flow in vessels and raises clotting risk; it is a feature of polycythemia, not of low hemoglobin. Option d is incorrect because is one specific type, caused by vitamin B12 or folate deficiency and marked by abnormally large red blood cells; the scenario gives no such cause.

Correct Answer: II and III

Deficiency of vitamin B12 or folate causes megaloblastic (macrocytic) anemia with abnormally large red blood cells, and vitamin B12 is also called cobalamin. Statements II and III are accurate. Option a is incorrect because statement I is wrong, since both vitamins are water-soluble and therefore not stored in the body, so adequate amounts must come from daily diet. Option c is incorrect because it relies on statements I and IV, yet the vitamins are not stored, and vegan diets are the exception lacking sufficient B12. Option d is incorrect because it adds statement IV, but vegan diets are named as the exception to balanced diets containing enough B12, not a source of excess.

Correct Answer: Obesity

Obesity is defined as an increased proportion of fat cells, resulting in excessive body weight in proportion to height. The documented description matches this definition, which distinguishes it from fluid, scar tissue or deficiency terms. Option a is incorrect because refers to scar tissue from disease or previous surgery that binds anatomic surfaces together, a structural finding unrelated to fat cell proportion. Option b is incorrect because describes abnormal fluid buildup in the abdominal cavity, not an increase in fat cells, so it does not fit this description. Option d is incorrect because results when too few macronutrients are consumed, leading to nutrient deficiencies, which is the opposite of excess body weight in proportion to height.

Correct Answer: Neuropathy

Diabetes mellitus causes nerve damage, often in the legs and feet, with pain, tingling, and numbness called paresthesia. These symptoms without ulcers or wounds point to neuropathy. Option b is incorrect because it involves circulatory problems in the lower extremities that lead to foot ulcerations and nonhealing wounds, and the documentation notes neither. Option c is incorrect because damage to blood vessels in the eyes produces reduced vision and eventually blindness, so it belongs to a different organ system. Option d is incorrect because this is diabetic kidney disease, which can progress to kidney failure needing dialysis or transplantation, not to sensory symptoms in the feet.

Correct Answer: Withdrawal management

Withdrawal management, also called detoxification, includes interventions aimed at managing the physical and emotional symptoms that occur after a person suddenly stops using a psychoactive substance, which matches the client described. Option a is incorrect because regional poison control centers advise on toxic ingestions and overdoses, which is a different problem from symptoms after abrupt cessation of a substance. Option b is incorrect because the term refers to the biological response of the body when too much of a substance is ingested, rather than a set of interventions. Option d is incorrect because it describes a disturbance in behavior or mental function during or after consumption of a substance, not care given after use stops.

Correct Answer: Adverse childhood experiences

Early life stressors, including physical, emotional, and sexual abuse, neglect, and household instability, are referred to as adverse childhood experiences. These early experiences can set the stage for substance use and sometimes escalate to substance use disorder. Option a is incorrect because concurrent mental health disorders are conditions that occur together with a substance use disorder, not the childhood stressors that raise later risk of substance use. Option b is incorrect because screening and brief intervention is an early intervention approach that identifies risk and offers brief education, rather than naming the early stressors that create risk. Option c is incorrect because withdrawal management, also called detoxification, is the set of interventions used when a person suddenly stops a psychoactive substance, so it is not a risk factor.

Correct Answer: Buprenorphine

Buprenorphine is an effective treatment for opioid withdrawal symptoms, but it can worsen them if not given carefully. The client should be in mild to moderate withdrawal, with a COWS score greater than 10, before the first dose. Option b is incorrect because tranquilizers appear among substances with significant physical withdrawal effects, and they are not presented as an opioid withdrawal treatment that needs careful timing. Option c is incorrect because alcohol is a psychoactive substance whose use and cessation produce withdrawal; it is not described as a medication that treats opioid withdrawal symptoms. Option d is incorrect because sedatives are named as substances that produce significant physical withdrawal effects when stopped, so they cause withdrawal rather than treat opioid withdrawal.

Correct Answer: Bell's palsy

Bell's palsy is an example of localized paralysis, since it temporarily paralyzes facial muscles. Hemiplegia, paraplegia and quadriplegia/tetraplegia are the common categories of generalized paralysis based on extent. Option a is incorrect because it is a listed category, describing paralysis of one side of the body, such as an arm and a leg on the same side. Option c is incorrect because damage to the cervical nerves produces paralysis in all limbs, which makes this a recognized extent category, also called tetraplegia. Option d is incorrect because this category covers paralysis of both legs and sometimes the torso, so it belongs among the extent-based categories.

Correct Answer: Immune attack on peripheral nerves

In inflammatory peripheral neuropathies such as Guillain-Barré syndrome and CIDP, the body's immune system mistakenly attacks peripheral nerves, damaging myelin and weakening signaling along the affected nerves. Option a is incorrect because this describes a seizure, which involves sudden, uncontrolled discharges of neurons in the brain rather than damage to peripheral nerves and their myelin. Option b is incorrect because a GABA imbalance is listed among the causes of seizures, so it belongs to a central nervous system problem, not CIDP. Option c is incorrect because dopamine loss is the pathophysiology of Parkinson's disease, a movement disorder, and is not described as the cause of inflammatory peripheral neuropathies.

Correct Answer: Unresponsive wakefulness syndrome

Unresponsive wakefulness syndrome (UWS) results from widespread brain damage. People with UWS are unconscious and unaware of their surroundings, but they can have periods of unresponsive alertness and may groan, move or show reflex responses. Option b is incorrect because it is defined by lack of measurable brain function and activity after an extended time, confirmed by tests showing no blood flow to the brain. Option c is incorrect because people in this state still show some self-awareness or awareness of their environment, such as following simple commands or giving yes or no responses. Option d is incorrect because a person in a coma is unconscious, unaware and unable to respond to pain or light, and the state generally lasts a few days or weeks.
