23 explained questions, each with the answer, a worked explanation, and something interactive to help it stick.
- Which of the following is NOT a function of blood?The option that is NOT a function of blood is the one describing hormone production or generating nerve impulses. Blood transports substances, regulates temperature and pH, and protects against infection and blood loss, but it does not manufacture hormones or conduct nerve signals.Read the guide
- Which of the Following Is NOT a Function of the Kidneys?The correct "not a function" answer is the non-renal task—typically producing insulin, bile, or digestive enzymes. The kidneys filter blood, regulate fluid and electrolytes, control blood pressure, balance pH, and secrete hormones like renin, erythropoietin, and calcitriol—but they do not make insulin, bile, or digestive enzymes.Read the guide
- Which of the Following Is NOT a Function of the Skeletal System?The skeletal system's five functions are support, protection, movement, mineral and fat storage, and blood cell production (hematopoiesis). The option that is NOT a skeletal function is typically hormone production, digestion, or heat/energy production, which belong to the endocrine, digestive, and muscular systems.Read the guide
- Which of the Following Is NOT a Function of the Skin?The skin does NOT produce blood cells (nor does it perform respiratory gas exchange or digestion). Its real functions are protection, temperature regulation, sensation, preventing water loss, excretion, and vitamin D synthesis - so the correct answer is the process the skin does not perform.Read the guide
- True or false: the thumb is the only saddle joint in the human body?False. The thumb's carpometacarpal joint is the classic saddle joint, but it is not the only one. The sternoclavicular joint (between the sternum and clavicle) is also a saddle joint, and some texts count additional joints as well.Read the guide
- A Patient Is in Need of Hydration — Which Type of Solution Are the Patient's Cells Most Likely In?The patient's cells are most likely in a hypertonic environment. Dehydration concentrates the fluid around the cells, so it pulls water out and the cells shrink. Treatment gives a hypotonic (or isotonic) IV solution to move water back into the cells.Read the guide
- How do you correctly label the components of the upper respiratory tract?The upper respiratory tract consists of the nose and nasal cavity (with nasal conchae and paranasal sinuses), the pharynx divided into nasopharynx, oropharynx, and laryngopharynx, and the larynx with its epiglottis. These structures warm, filter, and humidify air before it reaches the lungs.Read the guide
- Which of the following is NOT a function of the digestive system?The digestive system's core functions are ingestion, propulsion, mechanical and chemical digestion, absorption, and defecation. The correct "NOT" answer is any process outside these, such as gas exchange, blood filtration, or hormone circulation, which belong to the respiratory, urinary, or circulatory systems.Read the guide
- What does the RN Targeted Medical Surgical Cardiovascular Online Practice 2023 cover?It is an ATI RN med-surg cardiovascular practice exam. Core content includes myocardial infarction (MONA), heart failure and furosemide, infective endocarditis, dysrhythmias and ECG interpretation, and anticoagulation with heparin monitored by aPTT.Read the guide
- Which of the Following Best Describes What Alveoli Are?Alveoli are the tiny, thin-walled, balloon-like air sacs at the ends of the bronchioles in the lungs. Surrounded by capillaries, they are the site where oxygen enters the blood and carbon dioxide is removed during gas exchange.Read the guide
- ATI Pharmacology Made Easy 5.0: The Reproductive and Genitourinary System Test - Study GuideThis ATI module covers drugs acting on the reproductive and genitourinary systems: hormone replacement and transdermal testosterone, oral contraceptives with missed-dose teaching, sildenafil (Viagra) for erectile dysfunction, medications for urinary incontinence, and cervical-ripening agents.Read the guide
- How Do You Correctly Label the Anatomical Parts of a Kidney?From outside in and top to bottom: renal capsule, renal cortex, renal medulla (containing renal pyramids separated by renal columns), minor calyces draining into major calyces, then the renal pelvis, which narrows into the ureter. The hilum houses the renal artery, renal vein, and ureter.Read the guide
- A Medication With Antagonistic Properties Is One That Does What?A medication with antagonistic properties is one that blocks or counteracts the action of another substance, usually by binding to receptor sites and preventing the normal response. Examples include naloxone, which reverses opioids, and beta-blockers, which block adrenaline receptors.Read the guide
- RN: Alterations in Cardiovascular Function and Perfusion Assessment (ATI Study Guide)This ATI med-surg content covers assessment and nursing management of cardiovascular disorders: coronary artery disease and angina, heart failure, dysrhythmias (especially atrial fibrillation), pericarditis, cardiomyopathy, and valvular and peripheral venous disease, focusing on perfusion findings, key labs, and interventions with rationales.Read the guide
- RN Alterations in Kidney Function and Elimination: What Are the Key Assessment Findings?In acute kidney injury (AKI), expect increased BUN and creatinine, decreased GFR, and reduced urine output. Aminoglycosides and NSAIDs are nephrotoxic; fluid overload is managed with loop diuretics like furosemide and fluid restriction. AKI is often reversible; CKD is progressive and irreversible.Read the guide
- How do you correctly label the anatomical features of a neuromuscular junction?The key features are the myelinated motor neuron axon, the axon (synaptic) terminal containing acetylcholine vesicles and mitochondria, the synaptic cleft, and the motor end plate of the sarcolemma with junctional folds holding ACh receptors. These structures transmit the nerve signal to the muscle fiber.Read the guide
- Which of the following is not part of the skin?The hypodermis (subcutaneous layer) is not part of the skin. The skin proper consists of only two layers - the epidermis and the dermis. The hypodermis lies beneath the skin and anchors it to underlying muscle and bone, but is not counted as skin.Read the guide
- Correctly Label the Following Glands of the Endocrine SystemFrom head to lower body, the major endocrine glands are the pituitary and pineal (brain), thyroid and parathyroids (neck), thymus (chest), adrenal glands and pancreas (abdomen), and the ovaries in females or testes in males (pelvis).Read the guide
- Correctly Label the Following Meninges of the BrainFrom outermost to innermost, the three meninges are the dura mater (tough fibrous outer layer), the arachnoid mater (thin web-like middle layer), and the pia mater (delicate inner layer that clings directly to the brain surface).Read the guide
- How Do You Correctly Label the Components of the Kidney?From outside in, the main components are the renal cortex (outer layer), renal medulla (containing cone-shaped renal pyramids separated by renal columns), the minor and major calyces that funnel urine into the renal pelvis, the hilum where the renal artery, renal vein, and ureter enter or exit, and the fibrous renal capsule covering the whole organ.Read the guide
- How do you label the bony structures of the shoulder and upper limb?The shoulder girdle is formed by the clavicle and scapula (with the acromion, coracoid process, and glenoid cavity). The upper limb bones are the humerus (arm), radius and ulna (forearm), and the carpals, metacarpals, and phalanges (hand).Read the guide
- What Is on the ATI RN Learning System Mental Health Practice Quiz 2?The ATI RN Learning System Mental Health Practice Quiz 2 is a 40-item assessment split between Psychobiological Disorders (about 25 items) and Psychopharmacological Therapies (about 15 items). It tests anxiety, OCD, mood and psychotic disorders, plus safe use and monitoring of psychotropic medications.Read the guide
- Which of these cell junctions form a barrier to the passage of materials?Tight junctions. They fuse the plasma membranes of adjacent cells into a leak-proof seal that blocks materials from slipping between cells. This forces substances to pass through the cells themselves, making tight junctions the body's key barrier junction.Read the guide
