,Questions
1. A client is prescribed digoxin. Which finding indicates
toxicity? A) Serum potassium 4.0 mEq/L B) Visual
disturbances (yellow halos) C) Heart rate 72 bpm D) Blood
pressure 120/80 mmHg
Explanation: Visual disturbances such as yellow or green halos
are classic signs of digoxin toxicity. The nurse should assess for
other signs including nausea, vomiting, and bradycardia.
2. A nurse is preparing to administer heparin subcutaneously.
Which technique should the nurse use? A) Administer in
the deltoid muscle B) Administer with a 5/8-inch needle at
a 90-degree angle C) Massage the site after injection D)
Administer in the abdomen at a 15-degree angle
, Explanation: Heparin should be administered subcutaneously in
the abdomen with a 5/8-inch needle at a 90-degree angle. The
site should not be massaged.
3. A client is prescribed furosemide. Which food should the
nurse recommend to prevent hypokalemia? A) Bananas B)
Apples C) Bread D) Rice
Explanation: Bananas are high in potassium. Furosemide can
cause hypokalemia, so potassium-rich foods such as bananas,
oranges, and spinach should be encouraged.
4. A client is prescribed warfarin. Which laboratory test
should the nurse monitor? A) PT/INR B) PTT C) Platelet
count D) Hemoglobin
Explanation: Warfarin is monitored using the PT/INR. The
