Ordered: furosemide (Lasix) 20mg
Available: furosemide (Lasix) 2 mg/2 mL
Administer: ____mL
The Correct Answer is ["20"]
To administer the ordered dose of furosemide (Lasix) 20mg, you need to calculate the amount of mL required from the available solution. The available solution has a concentration of 2 mg/2 mL, which means that for every 2 mL of solution, there are 2 mg of furosemide. To find the amount of mL needed to deliver 20 mg of furosemide, you can use the following formula:
mL = (ordered dose / available dose) x available volume
Plugging in the values, we get:
mL = (20 mg / 2 mg) x 2 mL
mL = 10 x 2 mL
mL = 20 mL
Therefore, you need to administer 20 mL of the available solution to give the patient 20 mg of furosemide.

Correct Answer is B
Explanation
A. Regular deep respirations interspersed with periods of apnea:
This describes periodic breathing, which is different from Cheyne-Stokes respirations. Periodic breathing consists of regular cycles of deep respirations followed by periods of apnea.
B. A pattern of crescendo-decrescendo respirations followed by a period of apnea
Cheyne-Stokes respirations are characterized by a pattern of crescendo-decrescendo respirations, meaning that the depth and rate of breathing gradually increase and then decrease. This is followed by a period of apnea, during which there is a temporary cessation of breathing. The cycle then repeats.
C. Patient breathing less than 10 breaths per minute:
This describes bradypnea, which is an abnormally slow respiratory rate. Cheyne-Stokes respirations involve rhythmic, cyclical changes in respiratory rate and depth.
D. Patient breathing shallow and more than 24 breaths per minute:
This describes tachypnea, which is an abnormally fast respiratory rate. Cheyne-Stokes respirations are characterized by a distinct pattern of alternating crescendo-decrescendo respirations followed by apnea.
Correct Answer is A
Explanation
A. Carotid
The nurse should avoid assessing the carotid pulses bilaterally at the same time. The carotid arteries are major blood vessels supplying the head and neck with oxygenated blood. Simultaneously assessing both carotid pulses could potentially compromise blood flow to the brain, leading to a decrease in cerebral perfusion. This is particularly important in individuals with a history of cerebrovascular disease or other conditions affecting blood flow to the brain.
B. Brachial:
Assessing the brachial pulses bilaterally at the same time is generally acceptable. The brachial pulses are located in the upper arms.
C. Popliteal:
Assessing the popliteal pulses bilaterally at the same time is generally acceptable. The popliteal pulses are located behind the knee.
D. Femoral:
Assessing the femoral pulses bilaterally at the same time is generally acceptable. The femoral pulses are located in the groin area.
