A nurse is preparing to administer heparin at 1,000 units/hr via continuous IV infusion to a client who had a coronary artery bypass graft. Available is heparin 25,000 units in dextrose 5% in water in 250 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["10"]

ML

The formula to calculate the IV flow rate is:

mL/hr =

(Desired dose (units/hr)×Total volume (mL))/ Available dose​

Substituting the given values:

(1,000×250)/25000

= 250,000/25,000​

= 10ml/hr

Correct Answer is ["B","D"]

Explanation

A. Blood pressure: The client’s BP is 128/84 mm Hg, which is within the normal range. Although the client has chronic hypertension, this BP reading does not indicate an immediate concern.

B. Fetal heart rate: The fetal heart rate (FHR) is 165/min, which is tachycardia (normal FHR range is 110–160/min). Fetal tachycardia can indicate infection, maternal fever, fetal distress, or hypoxia and requires immediate follow-up.

C. Fetal station: The station is 0, which means the presenting part is at the level of the ischial spines. This is normal for a laboring client at 4 cm dilation and does not require immediate intervention.

D. Characteristics of amniotic fluid: The fluid is green, indicating the presence of meconium-stained amniotic fluid, which suggests fetal distress or hypoxia. This requires immediate follow-up, as the baby is at risk for meconium aspiration syndrome.

E. Duration of contraction: The contraction lasted 40 seconds, which is within the normal range (30–90 seconds). This is not an immediate concern.

Correct Answer is D

Explanation

A. Scant lochia rubra with a few small clots. Lochia rubra is expected in the early postpartum period, and small clots are normal unless excessive bleeding occurs.
B. Urine output 2,500 mL/day. Increased urine output is expected postpartum as the body eliminates excess fluid retained during pregnancy.
C. Bilateral ankle edema. Mild edema is common postpartum due to fluid shifts and typically resolves on its own.
D. 4+ deep-tendon reflexes. Hyperreflexia is a sign of central nervous system irritability and may indicate preeclampsia, which requires immediate evaluation.
