Exam 3 NURS 254 Practice Questions
and Correct Answers
1. The nurse would call the primary care provider immediately for which laboratory
result?
1. Hgb = 16 g/dL for a male client
2. Hct = 22% for a female client
3. WBC = 9 × 103 /mL3
4. Platelets = 300 × 103 /mL3 ✅Answer: 2. Rationale: Option 2 is very low and can
lead to death. The client's red blood cells participate in oxygenation. Options 1, 3, and 4
are within normal range and should not be reported to the primary care provider.
2. A 78-year-old male client needs to complete a 24-hour urine specimen. In planning
his care, the nurse realizes that which measure is most important? 1. Instruct the client
to empty his bladder and save this voiding to start the collection.
2. Instruct the client to use sterile individual containers to collect the urine.
3. Post a sign stating "Save All Urine" in the bathroom.
4. Keep the urine specimen in the refrigerator. ✅Answer: 3. Rationale: Option 3 is the
most important nursing measure. This will inform the staff that the client is on a 24-hour
urine collection. Option 1 is not appropriate since the first voided specimen is to be
discarded. Option 2 is not an appropriate nursing measure since the specimen
container is clean not sterile, and one container is needed—not individual containers.
Option 4 is inappropriate because some 24-hour urine collections do not require
refrigeration.
3. The client has a urinary health problem. Which procedure is performed using indirect
visualization? 1. Intravenous pyelography (IVP)
2. Kidneys, ureter, bladder (KUB)
3. Retrograde pyelography
4. Cystoscopy ✅Answer: 2. Rationale: A KUB is an x-ray of the kidneys, ureters, and
bladder. This does not require direct visualization. Option 1 is an IVP, an intravenous
pyelogram, which requires the injection of a contrast media. Option 3 is a retrograde
pyelography, which requires the injection of a contrast media. Option 4 is a cystoscopy,
which uses a lighted instrument (cystoscope) inserted through the urethra, resulting in
direct visualization.
4. Which noninvasive procedure provides information about the physiology or function
of an organ?
1. Angiography
2. Computerized tomography (CT)
3. Magnetic resonance imaging (MRI)
4. Positron emission tomography (PET) ✅Answer: 4. Rationale: This type of nuclear
scan demonstrates the ability of tissues to absorb the chemical to indicate the
, physiology and function of an organ. Option 1 is an invasive procedure that focuses on
blood flow through an organ. Options 2 and 3 provide information about density of
tissue to help distinguish between normal and abnormal tissue of an organ.
5. When assisting with a bone marrow biopsy, the nurse should take which action?
1. Assist the client to a right side-lying position after the procedure.
2. Observe for signs of dyspnea, pallor, and coughing.
3. Assess for bleeding and hematoma formation for several days after the procedure.
4. Stand in front of the client and support the back of the neck and knees. ✅Answer: 3.
Rationale: Bone marrow aspiration includes deep penetration into soft tissue and large
bones such as the sternum and iliac crest. This penetration can result in bleeding. The
client should be observed for bleeding in the days following the procedure. Option 1 is a
nursing action during a liver biopsy. Option 2 is a nursing action for a thoracentesis, and
Option 4 is a nursing action for a lumbar puncture.
6. During an assessment, the nurse learns that the client has a history of liver disease.
Which diagnostic tests might be indicated for this client? Select all that apply.
1. Alanine aminotransferase (ALT)
2. Myoglobin
3. Cholesterol
4. Ammonia
5. Brain natriuretic peptide or B-type natriuretic peptide (BNP) ✅Answer: 1 and 4.
Rationale: ALT is an enzyme that contributes to protein and carbohydrate metabolism.
An increase in the enzyme indicates damage to the liver. The liver contributes to the
metabolism of protein, which results in the production of ammonia. If the liver is
damaged, the ammonia level is increased. Options 2, 3, and 5 (myoglobin, cholesterol,
and BNP) are relevant for heart disease.
7. The nurse practitioner requests a laboratory blood test to determine how well a client
has controlled her diabetes during the past 3 months. Which blood test will provide this
information?
1. Fasting blood glucose
2. Capillary blood specimen
3. Glycosylated hemoglobin
4. GGT (gamma-glutamyl transferase) ✅Answer: 3. Rationale: A glycosylated
hemoglobin will indicate the glucose levels for a period of time, which is indicated by the
nurse practitioner. Options 1 and 2 will provide information about the current blood
glucose, not the past history. Option 4 is used to assess for liver disease. Cognitive
Level: Remembering. Client Need: Physiological Integrity. Nursing Process: Planning.
Learning Outcome: 34-2. 8.
8. The client is supposed to have a fecal occult blood test done on a stool sample. The
nurse is going to use the Hemoccult test. Which of the following indicates that the nurse
is using the correct procedure? Select all that apply.
1. Mixes the reagent with the stool sample before applying to the card.
2. Collects a sample from two different areas of the stool specimen.
