ACHA CERTIFICATION 2026 EXAMINATION
(HEALTHCARE ARCHITECTURE) COMPLETE
(180) CURRENT TESTING QUESTIONS AND
CORRECT ANSWERS WITH DETAILED
RATIONALES.
ACHA
Prepare for the ACHA Certification Examination (Healthcare
Architecture) with practice questions covering healthcare
facility design, building codes, patient safety, regulatory
compliance, planning principles, sustainable design, and
healthcare environment standards. Designed to improve
professional knowledge and boost confidence in designing safe
and efficient healthcare facilities. Suitable for architects,
healthcare planners, and design professionals specializing in
healthcare environments.
Multiple choice.
Section 1: Normal Structure and Function (Anatomy &
Physiology – 100%)
1. Which bone articulates with the acetabulum to form the hip
joint?
A. Tibia
B. Fibula
, Page 2 of 77
C. Femur
D. Patella
Answer: C. Femur
Rationale: The head of the femur articulates with the
acetabulum of the os coxae to form the coxofemoral (hip) joint.
This ball-and-socket joint allows for a wide range of movement in
the hind limb.
2. What is the primary function of the sebaceous glands?
A. Temperature regulation
B. Secrete sebum to lubricate skin and hair
C. Produce sweat for cooling
D. Detect tactile stimuli
Answer: B. Secrete sebum to lubricate skin and hair
Rationale: Sebaceous glands are holocrine glands that secrete
an oily substance called sebum, which waterproofs and
lubricates the skin and hair, preventing dryness and cracking.
3. Which part of the neuron receives incoming signals from other
neurons?
A. Axon
B. Dendrite
C. Soma
D. Myelin sheath
Answer: B. Dendrite
Rationale: Dendrites are branched extensions of a neuron that
act as the primary sites for receiving synaptic input from other
neurons and conducting electrical signals toward the cell body.

4. What is the normal resting membrane potential of a typical
neuron?
A. +30 mV
B. 0 mV
C. -70 mV
D. -90 mV
Answer: C. -70 mV
Rationale: The resting membrane potential of a typical neuron is
approximately -70 mV, maintained by the sodium-potassium
pump and selective permeability of the membrane to potassium
ions.
5. Which valve prevents backflow of blood from the left ventricle
into the left atrium?
A. Pulmonary valve
B. Tricuspid valve
C. Mitral (bicuspid) valve
D. Aortic valve
Answer: C. Mitral (bicuspid) valve
Rationale: The mitral (bicuspid) valve is located between the left
atrium and left ventricle. It closes during ventricular systole to
prevent regurgitation of blood into the atrium.
6. Which hormone is primarily responsible for regulating blood
calcium levels by increasing osteoclast activity?
A. Calcitonin
B. Parathyroid hormone (PTH)
C. Thyroid hormone
D. Insulin
, Page 4 of 77
Answer: B. Parathyroid hormone (PTH)
Rationale: Parathyroid hormone raises blood calcium levels by
stimulating osteoclasts to break down bone matrix, increasing
intestinal calcium absorption, and enhancing renal reabsorption
of calcium.
7. What is the functional unit of the kidney?
A. Alveolus
B. Glomerulus
C. Nephron
D. Collecting duct
Answer: C. Nephron
Rationale: The nephron is the microscopic structural and
functional unit of the kidney responsible for filtering blood,
reabsorbing needed substances, and forming urine.
8. Which lobe of the brain is primarily responsible for processing
auditory information?
A. Frontal lobe
B. Parietal lobe
C. Temporal lobe
D. Occipital lobe
Answer: C. Temporal lobe
Rationale: The temporal lobe contains the primary auditory
cortex, which processes sound information received from the
ears. It is also involved in memory and language comprehension.
9. Which type of muscle tissue is striated, branched, and under
involuntary control?
