A nurse is preparing to insert an indwelling urinary catheter for a client. Which of the following actions should the nurse plan to take?
Test the balloon on the indwelling urinary catheter before insertion.
Use one cotton swab to clean the client's urinary meatus.
Don sterile gloves before inserting the indwelling urinary catheter.
Apply an oil-based lubricant to the indwelling urinary catheter.
The Correct Answer is C
Choice A reason: Testing the balloon is important, but it is not the action to take immediately before insertion.
Choice B reason: While cleaning the urinary meatus is necessary, using one cotton swab is not sufficient for proper aseptic technique.
Choice C reason: Donning sterile gloves is essential to maintain an aseptic technique during catheter insertion to prevent infection.
Choice D reason: An oil-based lubricant should not be used as it can increase the risk of infection and is not compatible with the catheter material; a water-soluble lubricant is recommended.

Correct Answer is D
Explanation
Choice A reason: While bananas are well-known for their potassium content, with one medium banana containing about 451 mg of potassium, they are not the highest source among the options given.
Choice B reason: Spinach is also a good source of potassium, with 1 cup of cooked spinach offering about 830 mg. However, it still does not surpass the potassium content of a baked potato.
Choice C reason: Avocados contain potassium, with one-half cup providing 364 mg. Despite their health benefits,
they have less potassium compared to a baked potato.
Choice D reason: Baked potatoes contain the highest amount of potassium among the options listed. One medium baked potato has 929 mg of potassium, making it the best choice for someone at risk for hypokalemia.
Correct Answer is B
Explanation
Choice A reason: The left ventricle pumps oxygenated blood into the aorta and then to the rest of the body, not
directly to the lungs.
Choice B reason: The pulmonary artery is the correct answer because it carries deoxygenated blood from the right
ventricle of the heart to the lungs for oxygenation.
Choice C reason: The left atrium receives oxygenated blood from the lungs through the pulmonary veins, so it is not
involved in sending blood to the lungs.
Choice D reason: The pulmonary veins carry oxygenated blood from the lungs to the left atrium, not from the heart
to the lungs.
