A patient with CAD is asking the nurse about the mechanisms of the heart.
It would be appropriate for the nurse to respond that when the left ventricle contracts, it pushes blood through the semilunar valve to the:

Pulmonary vein.

Pulmonary artery.

Aorta.

Inferior vena cava.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

This statement is incorrect because the pulmonary vein carries oxygenated blood from the lungs to the left atrium, not from the left ventricle.

Choice B rationale:

This statement is incorrect because the pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, not from the left ventricle.

Choice C rationale:

This statement is correct. When the left ventricle contracts, it pushes blood through the aortic semilunar valve into the aorta, the largest artery in the body.

Choice D rationale:

This statement is incorrect because the inferior vena cava carries deoxygenated blood from the lower half of the body to the right atrium, not from the left ventricle.

Correct Answer is ["50"]

Explanation

The correct answer is 50 gtt/min.

Calculation: First, calculate the total volume to be administered per minute: 400 mL / 8 hr = 50 mL/hr. Then, convert hours to minutes: 50 mL/hr * 1 hr/60 min = 0.833 mL/min. Finally, calculate the drip rate: 0.833 mL/min * 60 gtt/mL = 50 gtt/min.

A. Ask the client's full name and date of birth. B. Verify the client's room number. C. Ask a family member to verify the client's identity. D. Check the client's name on the medication administration record (MAR)

Correct Answer is A

Explanation

Choice A rationale:

Asking the client’s full name and date of birth is the most reliable method of identification.

Choice B rationale:

Verifying the client’s room number is not reliable because room assignments can change.

Choice C rationale:

Asking a family member to verify the client’s identity is not always possible or reliable.

Choice D rationale:

Checking the client’s name on the medication administration record (MAR) is important but should be done in conjunction with direct client identification.
