The nurse is caring for a group of patients. Which patient is at highest risk for hypovolemia?

A patient who lost 2 liters of blood during surgery

A patient who received 6 liters of IV fluid

A patient with UTI on po iv meds

A patient with congestive heart failure

Answer and Explanation

The Correct Answer is A

A. A patient who lost 2 liters of blood during surgery: This is the most acute and severe form of hypovolemia due to significant blood loss, requiring immediate fluid replacement and hemodynamic monitoring.

B. A patient who received 6 liters of IV fluid: This patient is at risk for hypervolemia, not hypovolemia, due to fluid overload.

C. A patient with UTI on PO meds: While dehydration may occur, it is typically mild and does not cause hypovolemia.

D. A patient with congestive heart failure: CHF usually leads to fluid retention, making hypovolemia unlikely unless there are other complicating factors.

Correct Answer is B

Explanation

A. Peripheral pulses +1: Weak peripheral pulses indicate continued hypovolemia or dehydration. Effectiveness would be reflected in stronger pulses.

B. Urine output 200 mL/4 hr: Adequate urine output (≥30 mL/hr) indicates improved kidney perfusion and hydration status, suggesting effective treatment.

C. Urine specific gravity 1.04: This value is elevated, indicating continued dehydration; effective hydration would reduce this value to the normal range of 1.005-1.030.

D. Heart rate 104/min: Tachycardia is a compensatory response to dehydration. Improvement would manifest as a normalized heart rate (60-100 bpm).

Correct Answer is ["100"]

Explanation

To calculate the IV flow rate, the following formula is used:

Flowrate(gtt/min) = Volume /Time× Dropfactor(gtt/mL)

Given:

Volume = 100 mL
Time = 60 minutes
Drop factor = 60 gtt/mL

Flowrate(gtt/min)= 10060× 60

=1.67×60

=100gtt/min (rounded to the nearest whole number)
