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: The small intestine is not the starting point of the digestive process. It is where most of the digestion and absorption of nutrients occurs after the food has been processed in the stomach.
Choice B reason: The rectum is the final section of the large intestine, where feces are stored before being expelled. It is not involved in the initial stages of digestion.
Choice C reason: The stomach is involved in the early stages of digestion, particularly in the breakdown of proteins, but it is not the starting point. Food enters the stomach after being ingested through the mouth.
Choice D reason: The mouth is the correct starting location for the digestive process. Here, ingestion takes place, and mechanical digestion begins with chewing, while chemical digestion starts with enzymes in the saliva breaking down carbohydrates.
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.
