Pustule
Wheal

Choose the best answer (A–D). Which scenario most likely disrupts homeostasis via the integument?

Choose the best answer (A–D). Which statement about fever is most accurate?
Always harmful
Often beneficial by enhancing immune activity
Caused by antibody binding to RBCs
Prevents all bacterial replication absolutely
Choose the best answer (A–D). Autoimmunity is best defined as:
Failure to respond to any antigen
Adaptive response directed at self antigens
Excess neutrophils
Loss of all complement proteins
Choose the best answer (A–D). Secondary immune responses are faster because:
Innate cells are stronger
Memory lymphocytes respond rapidly to previously seen antigens
Fever is higher
Antigens are weaker
Choose the best answer (A–D). Which innate event most explains swelling during inflammation?
Vasoconstriction
Increased vascular permeability with protein leakage
Lymphatic collapse only
Platelet clumping in arteries
Choose the best answer (A–D). Which behavior most reduces melanoma risk?
Intermittent tanning bed use
Broad-spectrum sunscreen and protective clothing
Daily oiling of skin
Vitamin C supplements
Choose the best answer (A–D). Why is early detection of melanoma critical?
It never metastasizes
Deeper lesions have higher metastatic potential via lymphatics/blood
Only occurs in elderly
Always benign initially
Choose the best answer (A–D). Leukemia often leads to recurrent infections primarily because:
Platelets attack bacteria
Malignant WBCs crowd out functional leukocytes
RBCs are overproduced
Antibody levels are always high
Choose the best answer (A–D). Red streaks extending proximally from a skin infection imply:
Lymphangitic spread toward regional nodes
Healthy circulation returning
Viral exanthem
Allergic contact dermatitis
Choose the best answer (A–D). Completing an antibiotic course is emphasized because stopping early may:
Improve absorption
Increase resistance/relapse risk
Prevent side effects completely
Make cultures unnecessary
Choose the best answer (A–D). Proper use of antiseptic before insertion includes:
Back-and-forth scrub with antiseptic and allowing full dry time
Circular scrub then immediate insertion while wet
Using lotion after scrub
Touching the prepped area to test dryness
Choose the best answer (A–D). The safest response to suspected infiltration of a non-vesicant is to:
Increase the infusion rate
Stop infusion, remove catheter, elevate limb, and restart elsewhere
Keep line for future use
Apply heat and continue medication
Choose the best answer (A–D). During vesicant infusion, the patient reports burning and swelling. Best first action:
Flush vigorously to dilute
Stop infusion, leave catheter to aspirate, start extravasation protocol
Remove catheter immediately without aspiration
Lower the rate and observe
Choose the best answer (A–D). Which documentation element most prevents duplicate dosing?
Favorite hand
Time, medication/dose, route, and patient’s response
Brand of tourniquet
Number of visitors
Choose the best answer (A–D). Which statement about patency confirmation is most correct?
No pain guarantees patency
Easy push-pause saline flush with no swelling or resistance suggests a patent line
Blood return is always required in peripherals
A tight dressing ensures patency
Choose the best answer (A–D). For suspected anaphylactic shock, which pair best addresses the physiology?
Oral diphenhydramine + cooling blanket
IM epinephrine + rapid IV fluids
Oxygen only + rest
Topical steroids + ice
Choose the best answer (A–D). A wound culture should ideally be obtained:
After several antibiotic doses
Before the first antibiotic dose when feasible
Only if admitted
Never for skin infections
Choose the best answer (A–D). Which statement about infiltration vs extravasation is accurate?
Infiltration involves vesicant drugs
Extravasation is less urgent
Infiltration is non-vesicant leakage; extravasation is vesicant leakage and is an emergency
Both are treated by running fluids faster
Choose the best answer (A–D). Best site strategy for peripheral vesicant administration is to:
Use wrist or antecubital flexion points
Select a straight, well-supported forearm vein and the smallest gauge that safely delivers the drug
Prefer hand veins for mobility
Place near areas of infection
Choose the best answer (A–D). Which home instruction is best for a neutropenic teen on chemo?
Attend crowded concerts as usual
Eat raw sushi to maintain protein intake
Wash hands frequently; avoid sick contacts and raw/undercooked foods
Skip oral care to prevent gum bleeding
