MCA1 EXAM (2026/2027) QUESTIONS AND
CORRECT ANSWERS GRADED A+
A patient with a history of peptic ulcer disease has presented to the emergency
department with severe abdominal pain and a rigid, boardlike abdomen. The health
care provider suspects a perforated ulcer. Which interventions should the nurse
anticipate?
Providing IV fluids and inserting a nasogastric (NG) tube
Administering oral bicarbonate and testing the patient's gastric pH level
Performing a fecal occult blood test and administering IV calcium gluconate
Starting parenteral nutrition and placing the patient in a high-Fowler's position
Providing IV fluids and inserting a nasogastric (NG) tube
A perforated peptic ulcer requires IV replacement of fluid losses and continued
gastric aspiration by NG tube. Nothing is given by mouth, and gastric pH testing is
not a priority. Calcium gluconate is not a medication directly relevant to the
patient's suspected diagnosis, and parenteral nutrition is not a priority in the short
term.
After administration of a dose of metoclopramide, which patient assessment
finding would show the medication was effective?
,Decreased blood pressure
Absence of muscle tremors
Relief of nausea and vomiting
No further episodes of diarrhea
Relief of nausea and vomiting
Metoclopramide is classified as a prokinetic and antiemetic medication. If it is
effective, the patient's nausea and vomiting should resolve. Metoclopramide does
not affect blood pressure, muscle tremors, or diarrhea.
The nurse determines a patient has experienced the beneficial effects of therapy
with famotidine when which symptom is relieved?
Nausea
Belching
Epigastric pain
Difficulty swallowing
Epigastric pain
,Famotidine is an H2-receptor antagonist that inhibits parietal cell output of HCl
acid and minimizes damage to gastric mucosa related to hyperacidity, thus
relieving epigastric pain. It is not indicated for nausea, belching, and dysphagia.
The nurse is teaching a group of college students how to prevent food poisoning.
Which comment shows an understanding of foodborne illness protection?
"Eating raw cookie dough from the package is a great snack when you do not have
time to bake."
"Since we only have one cutting board, we can cut up chicken and salad vegetables
at the same time."
"To save refrigerator space, leftover food can be kept on the counter if it is in
sealed containers."
"When the cafeteria gave me a pink hamburger, I sent it back and asked for a new
bun and clean plate."
When the cafeteria gave me a pink hamburger, I sent it back and asked for a new
bun and clean plate."
The student who did not accept the pink hamburger and asked for a new bun and
clean plate understood that the pink meat may not have reached 160°F and could
be contaminated with bacteria. Improperly storing cooked foods, eating raw cookie
dough from a refrigerated package, and only using one cutting board without
washing it with hot soapy water between the chicken and salad vegetables could all
lead to food poisoning from contamination.
, The nurse is caring for a patient treated with IV fluid therapy for severe vomiting.
As the patient recovers and begins to tolerate oral intake, which food choice would
be most appropriate?
Iced tea
Dry toast
Hot coffee
Plain yogurt
Dry toast
Dry toast or crackers may alleviate the feeling of nausea and prevent further
vomiting. Water is the initial fluid of choice. Extremely hot or cold liquids and
fatty foods are generally not well tolerated.
The nurse teaches senior citizens at a community center how to prevent food
poisoning at social events. Which community member statement reflects accurate
understanding?
"Pasteurized juices and milk are safe to drink."
"Alfalfa sprouts are safe if rinsed before eating."
