A nurse is reviewing the morning laboratory results of electrolytes for four clients who are receiving digoxin. Which of the following clients should the nurse identify as being at risk for developing digoxin toxicity?
A client taking furosemide for chronic hypertension.
A client taking a potassium supplement twice a day.
A client taking aluminum hydroxide for gastric upset.
A client taking chlorpropamide for type 2 diabetes mellitus.
The Correct Answer is A
a. A client taking furosemide for chronic hypertension: Furosemide is a loop diuretic that can
lead to hypokalemia, which increases the risk of digoxin toxicity, as hypokalemia potentiates the effects of digoxin on the heart.
b. A client taking a potassium supplement twice a day: Potassium supplementation reduces the risk of digoxin toxicity, as hypokalemia is a risk factor for toxicity.
c. A client taking aluminum hydroxide for gastric upset: Aluminum hydroxide is an antacid and does not significantly affect digoxin levels.
d. A client taking chlorpropamide for type 2 diabetes mellitus: Chlorpropamide is an oral hypoglycemic agent and does not significantly affect digoxin levels.

Correct Answer is C
Explanation
a. An endometrial biopsy: An endometrial biopsy is not the preferred method for detecting cervical cancer. It is more commonly used to evaluate the endometrium.
b. CA 125: CA 125 is a tumor marker used more for ovarian cancer detection and monitoring, not cervical cancer.
c. Papanicolaou test: The Papanicolaou test, also known as a Pap smear, is the preferred method for detecting cervical cancer and precancerous changes.
d. Transvaginal ultrasound: While ultrasound may be used to evaluate gynecological conditions,
it is not the primary method for detecting cervical cancer; the Pap smear is the standard screening test.
Correct Answer is B
Explanation
a. Overusing a muscle while jogging: Overuse injuries are more commonly associated with strains, not sprains. Strains involve the muscles or tendons.
b. Twisting a ligament while walking: This is an example of a mechanism that can lead to a sprain. A sprain involves the stretching or tearing of ligaments, which connect bone to bone.
c. Impact injury on a joint from a fall: This is more likely to result in a sprain, as it can cause damage to ligaments.
d. Crush injury to a bone from blunt trauma: This type of injury is more likely to affect bones rather than ligaments or tendons, and it would not be considered a sprain or strain.
