A nurse is preparing to administer an injection of 0.25 mg subcutaneous terbutaline to a client who is in preterm labor. The amount available is 1 mg/ml. How many ml should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["0.25"]
Desired dose = 0.25 mg
Available concentration = 1 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 0.25 mg / 1 mg/mL
= 0.25 mL

Correct Answer is C
Explanation
A. Clamp the urinary catheter tubing: Clamping the catheter tubing is not appropriate because it can lead to bladder distention, increased pressure, and risk of bladder rupture. Maintaining continuous drainage is essential to prevent complications following prostate surgery.
B. Replace the indwelling urinary catheter with a smaller diameter catheter: Replacing the catheter is not the first intervention when clots and dark red blood are present. Smaller diameter catheters would actually be less effective in clearing clots and could worsen the blockage.
C. Irrigate the bladder with 20 to 30 mL of 0.9% sodium chloride irrigation: Manual irrigation helps to clear clots that may be obstructing the catheter, promoting continued drainage and reducing the risk of bladder distention. Gentle irrigation is the appropriate first step to manage clot formation.
D. Allow the tubing to hang below the drainage bag: The drainage tubing should always be positioned above the collection bag to maintain gravitational drainage. Letting the tubing hang below the bag would impair drainage and could lead to backflow and infection.
Correct Answer is B
Explanation
A: Image A shows a newborn wrapped in a blanket with generalized redness on the face but without distinct blotchy areas or pustules. This appearance is more consistent with normal transitional skin changes such as acrocyanosis or overall mild skin redness after birth. It does not match the appearance of erythema toxicum.
B: Image B shows a close-up of the newborn’s face with visible small red blotchy spots, especially around the cheeks and nose. This matches the classic presentation of erythema toxicum, a benign newborn rash appearing within the first 24 hours. It is characterized by red patches with possible small pustules scattered over the face and body.
