1. The nurse would call the primary care provider immediately for
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



which laboratory result?
i,- i,- i,-




1. Hgb = 16 g/dL for a male client
i,- i,- i,- i,- i,- i,- i,- i,- i,-




2. Hct = 22% for a female client
i,- i,- i,- i,- i,- i,- i,- i,-




3. WBC = 9 × 103 /mL3
i,- i,- i,- i,- i,- i,- i,-




4. Platelets = 300 × 103 /mL3
i,- Answer: 2. Rationale: Option 2
i,- i,- i,- i,- i,- i,-i,- i,- i,- i,- i,- i,- i,-



is very low and can lead to death. The client's red blood cells
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



participate in oxygenation. Options 1, 3, and 4 are within normal
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



range and should not be reported to the primary care provider.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-




2. A 78-year-old male client needs to complete a 24-hour urine
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



specimen. In planning his care, the nurse realizes that which
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



measure is most important? 1. Instruct the client to empty his
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



bladder and save this voiding to start the collection.
i,- i,- i,- i,- i,- i,- i,- i,- i,-




2. Instruct the client to use sterile individual containers to collect
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



the urine.
i,- i,-




3. Post a sign stating "Save All Urine" in the bathroom.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-

,4. Keep the urine specimen in the refrigerator.
i,- i,- Answer: 3.
i,- i,- i,- i,- i,- i,-i,- i,- i,- i,-



Rationale: Option 3 is the most important nursing measure. This
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



will inform the staff that the client is on a 24-hour urine
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



collection. Option 1 is not appropriate since the first voided
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



specimen is to be discarded. Option 2 is not an appropriate
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



nursing measure since the specimen container is clean not sterile,
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



and one container is needed—not individual containers. Option 4
i,- i,- i,- i,- i,- i,- i,- i,- i,-



is inappropriate because some 24-hour urine collections do not
i,- i,- i,- i,- i,- i,- i,- i,- i,-



require refrigeration. i,-




3. The client has a urinary health problem. Which procedure is
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



performed using indirect visualization? 1. Intravenous
i,- i,- i,- i,- i,- i,-



pyelography (IVP) i,- i,-




2. Kidneys, ureter, bladder (KUB)
i,- i,- i,- i,- i,-




3. Retrograde pyelography
i,- i,- i,-




4. Cystoscopy
i,- Answer: 2. Rationale: A KUB is an x-ray of the i,-i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



kidneys, ureters, and bladder. This does not require direct
i,- i,- i,- i,- i,- i,- i,- i,- i,-



visualization. Option 1 is an IVP, an intravenous pyelogram, whichi,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



requires the injection of a contrast media. Option 3 is a
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



retrograde pyelography, which requires the injection of a contrast
i,- i,- i,- i,- i,- i,- i,- i,- i,-



media. Option 4 is a cystoscopy, which uses a lighted instrument
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



(cystoscope) inserted through the urethra, resulting in directi,- i,- i,- i,- i,- i,- i,- i,-



visualization.

,4. Which noninvasive procedure provides information about the
i,- i,- i,- i,- i,- i,- i,- i,-



physiology or function of an organ? i,- i,- i,- i,- i,- i,-




1. Angiography
i,- i,-




2. Computerized tomography (CT)
i,- i,- i,- i,-




3. Magnetic resonance imaging (MRI)
i,- i,- i,- i,-




4. Positron emission tomography (PET)
i,- Answer: 4. Rationale:
i,- i,- i,- i,-i,- i,- i,- i,- i,-



This type of nuclear scan demonstrates the ability of tissues to
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



absorb the chemical to indicate the physiology and function of an
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



organ. Option 1 is an invasive procedure that focuses on blood
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



flow through an organ. Options 2 and 3 provide information
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



about density of tissue to help distinguish between normal and
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



abnormal tissue of an organ. i,- i,- i,- i,-




5. When assisting with a bone marrow biopsy, the nurse should
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



take which action?
i,- i,- i,-




1. Assist the client to a right side-lying position after the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



procedure. i,-




2. Observe for signs of dyspnea, pallor, and coughing.
i,- i,- i,- i,- i,- i,- i,- i,- i,-




3. Assess for bleeding and hematoma formation for several days
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



after the procedure.
i,- i,- i,-




4. Stand in front of the client and support the back of the neck
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



and knees.
i,- Answer: 3. Rationale: Bone marrow aspiration
i,-i,- i,- i,- i,- i,- i,- i,- i,-



includes deep penetration into soft tissue and large bones such
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



as the sternum and iliac crest. This penetration can result in
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-

, bleeding. The client should be observed for bleeding in the days
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



following the procedure. Option 1 is a nursing action during a
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



liver biopsy. Option 2 is a nursing action for a thoracentesis, and
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



Option 4 is a nursing action for a lumbar puncture.
i,- i,- i,- i,- i,- i,- i,- i,- i,-




6. During an assessment, the nurse learns that the client has a
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



history of liver disease. Which diagnostic tests might be indicated
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



for this client? Select all that apply.
i,- i,- i,- i,- i,- i,- i,-




1. Alanine aminotransferase (ALT)
i,- i,- i,- i,-




2. Myoglobin
i,- i,-




3. Cholesterol
i,- i,-




4. Ammonia
i,- i,-




5. Brain natriuretic peptide or B-type natriuretic peptide (BNP)
i,- i,- i,- i,- i,- i,- i,- i,- i,-i,-



Answer: 1 and 4. Rationale: ALT is an enzyme that contributes
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



to protein and carbohydrate metabolism. An increase in the
i,- i,- i,- i,- i,- i,- i,- i,- i,-



enzyme indicates damage to the liver. The liver contributes to the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



metabolism of protein, which results in the production of i,- i,- i,- i,- i,- i,- i,- i,- i,-



ammonia. If the liver is damaged, the ammonia level is increased.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



Options 2, 3, and 5 (myoglobin, cholesterol, and BNP) are relevant
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



for heart disease.
i,- i,-




7. The nurse practitioner requests a laboratory blood test to
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



determine how well a client has controlled her diabetes during
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



the past 3 months. Which blood test will provide this
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



information? i,-
