75 FREE NCLEX EXAM WITH 100% CORRECT
ANSWER: 2026



The nurse is taking the health history of a patient being treated for Emphysema
and Chronic Bronchitis. After being told the patient has been smoking cigarettes
for 30 years, the nurse expects to note which assessment finding?


1. Increase in Forced Vital Capacity (FVC)
2. A narrowed chest cavity
3. Clubbed fingers
4. An increased risk of cardiac failure CORRECT ANSWER: 1. Increase in Forced
Vital Capacity (FVC)
Forced Vital Capacity is the volume of air exhaled from full inhalation to full
exhalation. A patient with COPD would have a decrease in FVC. Incorrect.


2. A narrowed chest cavity
A patient with COPD often presents with a 'barrel chest,' which is seen as a
widened chest cavity. Incorrect.

,3. Clubbed fingers - CORRECT
Clubbed fingers are a sign of a long-term, or chronic, decrease in oxygen levels.


4. An increased risk of cardiac failure
Although a patient with these conditions would indeed be at an increased risk for
cardiac failure, this is a potential complication and not an assessment finding.
Incorrect.


The nurse is taking the health history of a 70-year-old patient being treated for a
Duodenal Ulcer. After being told the patient is complaining of epigastric pain, the
nurse expects to note which assessment finding?


1. Melena
2. Nausea
3. Hernia
4. Hyperthermia CORRECT ANSWER: 1. Melena - CORRECT
Melena is the finding that there are traces of blood in the stool which presents as
black, tarry feces. This is a common manifestation of Duodenal Ulcers, since the
Duodenum is further down the gastric anatomy.


2. Nausea
Nausea may be present, but is a generalized symptom and by itself doesn't
indicate a Duodenal Ulcer. Incorrect.


3. Hernia

,A Hernia is a protrusion of a segment of the abdomen through another abdominal
structure. It is not associated with an Ulcer and is a condition, not an assessment
finding. Incorrect.


4. Hyperthermia
Hyperthermia, a high temperature, is not an assessment finding of a Duodenal
Ulcer. Incorrect


A nurse is providing discharge teaching for a patient with severe Gastroesophogeal
Reflux Disease. Which of these statements by the patient indicates a need for
more teaching?


1. "I'm going to limit my meals to 2-3 per day to reduce acid secretion."


2. "I'm going to make sure to remain upright after meals and elevate my head
when I sleep"


3. "I won't be drinking tea or coffee or eating chocolate any more."


4. "I'm going to start trying to lose some weight." CORRECT ANSWER: 1. "I'm
going to limit my meals to 2-3 per day to reduce acid secretion."
CORRECT - Large meals increase the volume and pressure in the stomach and
delay gastric emptying. It's recommended instead to eat 4-6 small meals a day.


2. "I'm going to make sure to remain upright after meals and elevate my head
when I sleep"
Incorrect - This is a correct verbalization of health promotion for GERD.

, 3. "I won't be drinking tea or coffee or eating chocolate any more."
Incorrect - This is a correct verbalization of health promotion for GERD.


4. "I'm going to start trying to lose some weight."
Incorrect - This is a correct verbalization of health promotion for GERD.

Ulcer. On assessing lab results, the nurse finds that the patient's blood pressure is
95/60, pulse is 110 beats per minute, and the patient reports epigastric pain. What
is the PRIORITY intervention?


1. Start a large-bore IV in the patient's arm
2. Ask the patient for a stool sample
3. Prepare to insert an NG Tube
4. Administer intramuscular morphine sulphate as ordered CORRECT ANSWER:
1. Start a large-bore IV in the patient's arm
CORRECT - The nurse should suspect that the patient is haemorrhaging and will
need need a fluid replacement therapy, which requires a large bore IV.


2. Ask the patient for a stool sample
Incorrect - While this is useful in the diagnosis and assessment of Peptic Ulcer
Disease, it is not the priority intervention.
