VALUES – memorize normal lab values and be able to
A 66 year old woman is admitted to the
hospital with flu-like symptoms. When taking the history the nurse
learns that the patient has been taking Lanoxin (Digoxin) 0.125 mg PO
daily and furosemide (Lasix) 40 mg PO daily for the three years. Last
month her physician changed the prescription for Digoxin to 0.25 mg qd.
The nurse would expect the physician to order which of the following
serum electrolytes and digoxin level
B. WBC and hemoglobin and hematocrit
C. Cardiac enzymes and an ABG
D. Blood cultures and analysis
Correct Answer: A
The nurse plans care for a 15-year-old girl
admitted with complaints of fever, vomiting and diarrhea. The nurse
writes the following nursing diagnosis on the patient’s care plan:
"fluid volume deficit". Which of the following changes in laboratory
values would demonstrate an improvement in the patient’s condition?
urine specific gravity, 1.015; hematocrit, 37%
B. urine specific gravity, 1.030; hematocrit, 47%
C. urine specific gravity, 1.015; hematocrit, 46%
D. urine specific gravity, 1.025; hematocrit, 35%
order to correctly answer this question, you must know:
normal levels of hematocrit (male and female) and specific gravity of
- how hematocrit and
specific gravity levels are affected by a fluid volume deficit
volume deficit occurs when water and electrolytes are lost in the same
proportion as they exist in the body. When a patient is dehydrated,
both specific gravity of urine and hematocrit become elevated.
Answer: letter B (Hct in females: 40-48%, specific
gravity: 1.010 – 1.030)
TAKE CARE OF THE PATIENT,
THEN THE EQUIPMENT
A 36 year old woman sustains a fractures left
femur in a car accident. She is placed in balanced suspension skeletal
traction using a Thomas splint and a Pearson attachment. The patient
tells the nurse that she has "terrible" pain in her left thigh.
Initially, the nurse should:
determine that all the weights and ropes from the traction apparatus
are in line and hanging free
B. ask the patient for more information about the location
and characteristics of the pain
C. check the splint and Pearson attachment to make sure they
are appropriately positioned
D. explain to the patient she is experiencing in the affected
leg a common occurrence
Answer: letter B (The nurse should focus on
assessing the patient and her problem before assessing the function of
the equipment. All complaints of pain must be thoroughly investigated
by the nurse.)
This answer has you checking the equipment , not the patient. Your
first concern must be the patient, not the traction
C. same as letter A
D. Any complaints of pain are considered abnormal and should be
thoroughly investigated by the nurse.
ADMINISTRATION – remember the "rights" in
if you did not know the information about the medication, sometimes you
are able to select the correct answer by knowing the diagnosis.
- Know the side
effects and nursing implications of medications
A 45 year old man returns to the clinic two
weeks after being started on allopurinol (Zyloprim) 200 mg PO daily.
The nurse reviews information about this medication with the patient.
Which statement by the patient indicates that the teaching was
"I should take my medication on an empty stomach."
B. "I should take my medication with orange juice."
C. "I should increase my intake of protein."
D. "I should drink at least eight glasses of water every day."
Answer: letter D – Zyloprim can cause renal
calculi….drink 3000 ml/day to reduce formation of kidney stones.
