NU129 Final exam Practice Questions
and Answers

Urinary anti-infectives are used only in urinary tract infections. What causes urinary anti-infectives to be

so effective in treating UTIs? - Ans:✔✔-They act specifically within the urinary tract


Urinary tract anti-infectives act specifically within the urinary tract to destroy bacteria, either through a

direct antibiotic effect or through acidification of the urine. They are not used in systemic infections

because they do not attain therapeutic plasma levels. These drugs are not excreted through the liver, and

they do not sterilize the feces.


The nurse is preparing to administer a sulfonamide to a client when the client states, "I woke up this

morning with a lot of sores in my mouth." What is the nurse's next best action? - Ans:✔✔-"I'm going to

contact your health care provider before I administer your medication."




The nurse should withhold the medication and notify the health care provider when a client develops an

adverse reaction. In this case, the client developed numerous mouth sores overnight so it must be

addressed before proceeding with medication administration. The other responses do not state that the

medication should be withheld.

Phenazopyridine may cause a yellowish discoloration of the skin or sclera. It is not related to the

nitrofurantoin, does not indicate the development of hepatitis, and is not a result of the urinary tract

infection.


A patient has been prescribed a tetracycline drug for Rocky Mountain spotted fever. The patient also

takes antacids. Which of the following effects is likely to occur due to an interaction between the two

drugs? - Ans:✔✔-Decreased absorption of tetracycline

Interaction of antacids with a tetracycline drug causes decreased absorption of tetracycline. Increased

action of neuromuscular-blocking drugs and increased profound respiratory depression are the result of

interaction between neuromuscular-blocking drugs and tetracyclines. Increased risk of bleeding is a

result of interaction between anticoagulants and tetracyclines.

Sulfonamides may cause the urine and skin to take on an orange-yellow color. Crystalluria may occur

during administration of a sulfonamide. Often this problem can be prevented by increasing fluid intake

during treatmeent. It is important to instruct the patient to drink a full glass of water when taking an oral

sulfonamide and to drink at least 8 large glasses of water each day until therapy is finished. Although

drinking water will prevent dehydration, this is not a side effect of this type of drug therapy nor is fluid

volume disturbance. There is also no proof that sulfonamides cause hypokalemia.

The nurse should instruct the patient to drink more fluids, so that the formation of crystals in urine

(crystalluria) can be prevented. Unlike patients with thrombocytopenia, patients with crystalluria do not

bruise easily so there is no need to exercise extra caution. Drinking cranberry juice is recommended for

relieving symptoms of urinary tract infections, not for crystalluria. There is no need to shift the patient to

a soft diet or a liquid diet.


A 48-year-old female patient has acute pyelonephritis. Her urine pH is below 5.5, which indicates that it

is acidic. Which of the following medications would serve to decrease the acidity of her urine? - Ans:✔✔-

Sodium bicarbonate


Correct


Explanation: Giving sodium bicarbonate to a patient who has acidic urine may help reduce its acidity. The

nurse could also advise the patient to drink at least 1.5 L of water daily. Dihydrofoli... (more)


Giving sodium bicarbonate to a patient who has acidic urine may help reduce its acidity. The nurse could

also advise the patient to drink at least 1.5 L of water daily. Dihydrofolic acid, an agent that promotes the

growth of new bacteria in the urinary tract, would not help alter the urine pH. Sulfonamide and

gentamicin are drugs given to patients with urinary tract infections, and are not designed to alter the pH

of urine.


(see full question) The nurse is caring for four patients on a medical floor. For which of the following

patients would she suspect the physician might order a sulfonamide? - Ans:✔✔-A 35-year-old woman

with a urinary tract infection and a history of ulcerative colitis
