c 39 GRADE A QUESTIONS WITH ANSWERS
A patient has had chronic diarrhea for 3 months. He also suffers from repeated bouts of
vomiting. A nurse sends the patient's samples for laboratory studies. The laboratory
reports indicate hypokalemia. Which signs is the nurse likely to find on the patient
during examination? Select all that apply. - (correct answer)In hypokalemia, the patient
experiences bilateral muscle weakness that begins in the quadriceps and ascends to
the respiratory muscles. Signs of digoxin toxicity at normal digoxin levels are also seen.
Positive Chvostek's sign, hyperactive reflexes, and numbness of the circumoral region
are signs of hypocalcemia.
A patient is receiving treatment for chronic diarrhea. The nurse advises the patient to
eat food items rich in potassium. What is the reason behind promoting a potassium-rich
diet?
Correct1
Potassium improves smooth, skeletal, and cardiac muscle function. - (correct
answer)Potassium is required for normal functioning of smooth, skeletal, and cardiac
muscles as it helps to maintain resting membrane potential. Phosphate is required for
production of ATP, not potassium. Potassium does not decrease muscle wasting.
Magnesium acts as a cofactor for various enzymes.
Which veins are commonly used for peripheral intravenous (IV) therapy in adults?
Select all that apply. - (correct answer)The metacarpal, median cubital, and cephalic
veins are commonly used for peripheral IV therapy in adults, as they are larger in
diameter and reduce the risk of hematomas. Foot veins are not used in adults due to
the risk of thrombophlebitis. Scalp veins are used in newborns and infants but not in
adults.
STUDY TIP: If you are a visual learner, draw a person with three peripheral IV lines: one
in a metacarpal vein, one in the median cubital vein, and the third in the cephalic vein.
Then draw an infant next to the person and show a scalp IV in the infant. Label each IV
to help connect your visual and auditory memories. The act of drawing, as well as the
final picture, will help your memory.
The nurse is teaching a group of nursing students about the acid-base regulation
process. What should the nurse teach the students regarding the excretion of carbonic
