A nurse is asked to measure exactly 10 mL of medicine. Which tool is most reliable?
Beaker
Measuring cylinder
Volumetric pipette
Test tube
A student picks up a hot beaker using bare hands wrapped in tissue. This is unsafe because:
Tissue transfers heat quickly and may tear
Beakers explode when touched with paper
Tissue increases the weight of the beaker
Heat makes the beaker slippery only
Which practice is correct when handling a microscope?
Carry by the stage with one hand
Hold the arm with one hand and support base with the other
Tilt the microscope for easier viewing
Keep the objective lens facing the wall when not in use
Lab equipment is grouped into 'measuring, heating, and holding' categories primarily to:
Make the storage shelves look uniform
Reduce the risk of misuse and accidents
Shorten time spent during cleaning
Allow students to memorize faster
Which is the safest action before igniting a spirit lamp?
Keep sleeves loose for comfort
Ensure alcohol containers are capped and away
Place lamp close to paper notes
Light it while classmates are still passing
When an alcohol spill occurs near electrical wires, the first step is to:
Call attention and disconnect the power source
Wipe it immediately with bare hands
Cover it with a cloth and ignore it
Sprinkle water and continue work
The liver is located _____ to the diaphragm.
Superior
Inferior
Posterior
Lateral
The big toe is _____ to the little toe.
Lateral
Medial
Proximal
Distal
A patient lying flat on the back with palms up is in which position?
Prone
Supine
Fowler's
Lateral
Which plane divides the body into anterior and posterior sections?
Sagittal
Frontal (coronal)
Transverse
Oblique
A CT scan across the abdomen producing top and bottom views uses which plane?
Sagittal
Transverse
Coronal
Longitudinal
Nurses use the anatomical position when documenting to:
Save time writing notes
Avoid confusion when describing locations
Reduce hospital expenses
Improve drawing accuracy
The scapula is _____ to the sternum.
Anterior
Medial
Posterior
Distal
Which step comes first when using a compound microscope?
Place slide and use coarse focus on low power
Switch immediately to high power objective
Adjust fine focus before turning on light
Apply immersion oil without a slide
Why is a stain such as iodine added to onion cells?
To enlarge the cells permanently
To increase visibility of internal parts
To kill all bacteria on the slide
To flatten the specimen
A cheek cell observed under the microscope will show:
Nucleus and membrane but no cell wall
Cell wall and chloroplasts
Chloroplasts and large vacuole
Only ribosomes
Why should coarse adjustment never be used with high power?
It causes shaking of the table
It may crack the slide and damage the lens
It prevents light from passing
It lowers magnification
Bacteria require oil immersion because:
Their size is too small for light resolution
They absorb stains too easily
They have thick cell walls
They reflect less light
Rod-shaped bacteria are classified as:
Spirilla
Cocci
Bacilli
Vibrios
Which structure is present in both plant and animal cells?
Chloroplast
Cell wall
Cytoplasm
Plastids
Bubbling in the vinegar-chalk experiment indicates:
Carbon dioxide release due to acid reacting with calcium carbonate
Oxygen release that strengthens bones
Protein breakdown inside bone
Heat being produced
After 2 hours in vinegar, chalk becomes soft and brittle. This models:
Bone strengthening during exercise
Loss of calcium salts in osteoporosis
Bacterial infection in bone
Formation of new cartilage
Elderly patients are advised to take calcium supplements because:
Calcium prevents muscle cramps only
Calcium delays skin wrinkling
Calcium maintains bone mineral density
Calcium prevents kidney stones
A nurse uses the chalk-vinegar demo during health teaching because it:
Exactly measures patient bone density
Visually shows how acids can weaken bones
Cures weak bones through analogy
Demonstrates muscle fatigue
A patient who consumes multiple soft drinks daily may develop weak bones because:
Soda acids can contribute to calcium leaching
Soda is free of calcium
Soda stimulates bone growth
Soda contains protective proteins
A thin layer of tightly packed cells lining blood vessels is:
Connective tissue
Muscle tissue
Nervous tissue
Epithelial tissue
Which is a feature of skeletal muscle under the microscope?
Single nucleus per fiber, no striations
Branching fibers with intercalated discs
Multiple nuclei and striations
No visible fibers
A biopsy shows porous trabeculae and fragile structure. Likely diagnosis:
Osteoporosis
Arthritis
Pneumonia
Stroke
Connective tissue is distinguished from epithelial tissue by:
Abundant extracellular matrix
Presence of striations
Presence of intercalated discs
Tight junctions only
Why must nurses recognize tissue types in wounds?
To improve wound care and anticipate healing
To reduce exam questions in class
To shorten patient records
To draw tissues accurately
Stronger grip in the dominant hand occurs because:
Nerves are fewer in the dominant hand
Muscles adapt and strengthen with daily use
The dominant hand never fatigues
Tendons are shorter in that hand
Bulging veins during grip test indicate:
Increased venous pressure from muscle contraction
Arteries are blocked
Heart has stopped pumping
Nerves are damaged
Two subjects perform grip endurance: one lasts longer. The difference is due to:
Better endurance and conditioning
Larger heart size only
Slower nerve function
Different bone density
Hand trembling after repeated grip squeezes indicates:
Muscle fatigue
Muscle healing
Stroke recovery
Bone weakness
Nurses assess grip strength in patients primarily to:
Detect muscle weakness and nerve problems
Check for heart rate
Assess vision
Diagnose kidney function
Fingertips are more sensitive than forearm skin because:
Receptors are denser with smaller receptive fields
Fingertips have thicker skin
Fingertips have fewer nerves
Blood vessels are absent in fingertips
Why is tactile precision important for nurses inserting IV lines?
To palpate veins accurately and minimize errors
To shorten procedure time only
To replace visualization entirely
To reduce hospital costs
Loss of two-point discrimination after a burn suggests:
Damage to cutaneous receptors
Increased receptor density
Normal skin healing
Improved sensitivity
A diabetic patient unable to detect two points on the sole may have:
Peripheral neuropathy
Stroke
Pneumonia
Muscle strain
Sensitivity is poorer at the back of the neck because:
Receptive fields are larger and receptor density lower
Nerves are closer to the brain
Muscles are weaker
Skin is thinner
Nurses use knowledge of receptor distribution mainly to:
