High-Yield MCQs with Verified Answers &
Comprehensive Rationales (Latest Edition)
Question 1
What is the primary function of the mitochondria in a eukaryotic cell?
A) Protein synthesis
B) Lipid metabolism
C) ATP production via cellular respiration
D) Waste disposal
Rationale: Mitochondria are known as the powerhouse of the cell, where the
majority of ATP is produced during cellular respiration.
Question 2
Which marketing mix element refers to the specific combination of advertising,
personal selling, sales promotion, public relations, and direct marketing tools a
,company uses?
A) Product
B) Price
C) Place
D) Promotion
Rationale: The promotional mix (or integrated marketing communications)
consists of these specific tools to communicate customer value.
Question 3
In nursing, which of the following is considered a subjective assessment
finding?
A) Blood pressure 120/80 mmHg
B) Patient reports pain level as 7/10
C) Heart rate of 90 bpm
D) Observation of a skin rash
Rationale: Subjective data is what the patient says (symptom), while objective
data is what the nurse observes or measures (sign).
Question 4
In a patient with a newly created ileostomy, which physiological alteration puts
them at the highest risk for fluid and electrolyte imbalances during the
immediate postoperative period?
A) Increased absorption of fat-soluble vitamins
B) Loss of the colon's ability to reabsorb water and sodium
C) Hypersecretion of gastric acid into the duodenum
D) Decreased transit time through the jejunum
Rationale: The colon is the primary site for water and sodium reabsorption.
When it is bypassed or removed, the body loses this regulatory capacity,
leading to a high-volume liquid output from the ileostomy that can quickly
result in dehydration and hyponatremia.
,Question 5
When assessing a stoma on the first postoperative day, the nurse notes that the
stoma is flush with the skin and slightly edematous. What is the most
appropriate action?
A) Apply a rigid convex wafer with an ostomy belt immediately.
B) Notify the surgeon to schedule an emergency surgical revision.
C) Gently probe the edges with a sterile cotton applicator to check for
separation.
D) Document the findings and monitor the stoma output and perfusion
closely.
Rationale: Mild edema is a normal finding in the immediate postoperative
period. While a flush stoma may eventually require a convex pouching
system, structural modifications should be delayed until early postoperative
swelling subsides and the stoma matures. Close monitoring of color
(perfusion) and output is the priority.
Question 6
A patient with an ileal conduit notices that their urine contains thick, stringy
strands of white mucus. What instruction should the wound, ostomy, and
continence (WOC) nurse provide?
A) "Drink less fluid to reduce the thickness and volume of the mucus."
B) "This is a normal finding because the intestinal segment continues to
secrete mucus."
C) "You need an immediate prescription for oral antibiotics to treat an
infection."
D) "Irrigate the conduit daily with a dilute acetic acid solution to dissolve it."
Rationale: An ileal conduit is constructed using a isolated segment of the
ileum. Because intestinal mucosa naturally secretes mucus to lubricate stool,
, it will continue to produce mucus even when functioning as a urinary
conduit. This is expected and does not indicate an infection.
Question 7
During a home health visit, an ostomy patient presents with a deep, irregular
ulcer on the peristomal skin that features a violaceous (purple) border and
undermined edges. The patient describes the lesion as extremely painful. Which
condition should the nurse suspect?
A) Pyoderma gangrenosum
B) Candidiasis
C) Irritant contact dermatitis
D) Mechanical skin stripping
Rationale: Pyoderma gangrenosum is an inflammatory neutrophilic
dermatosis that is strongly associated with systemic diseases like inflammatory
bowel disease (IBD). It classically presents as painful, irregular ulcers with
violaceous borders and undermined edges, and it must not be treated as a
simple infection or mechanical wound.
Question 8
When choosing a stoma site during preoperative planning, which anatomical
location is preferred to provide support and minimize the risk of a parastomal
hernia?
A) Lateral to the midaxillary line
B) Within an abdominal skin crease or fold
C) Through the body of the rectus abdominis muscle
D) Below the symphysis pubis line
Rationale: Bringing the stoma out through the rectus abdominis muscle
provides structural support to the abdominal wall around the stoma. This
significantly reduces the incidence of late complications like parastomal
