A nurse is assessing a client who is experiencing hypovolemia. Which of the following findings should the nurse expect?
Oliguria
Hypertension
Bradycardia
Peripheral edema
The Correct Answer is A
A. Oliguria, or decreased urine output, is a common finding in hypovolemia due to reduced renal perfusion and decreased blood flow to the kidneys.
B. Hypertension is unlikely in hypovolemia; instead, clients typically exhibit hypotension due to decreased circulating blood volume.
C. Bradycardia is not a typical finding in hypovolemia; instead, tachycardia is more commonly observed as the body compensates for reduced blood volume.
D. Peripheral edema is associated with fluid overload rather than hypovolemia, as a decrease in blood volume usually leads to less fluid accumulation in the tissues.

Correct Answer is A
Explanation
A. A phlebotomist collecting blood from clients who have HIV is at the greatest risk due to the potential for exposure to infected blood, especially if safety precautions are not properly followed.
B. A nurse working for an insurance company collecting urine samples is at a lower risk, as urine is not a primary mode of HIV transmission.
C. A personal trainer working with a client who has HIV may be at risk if there are open wounds, but the risk is less compared to healthcare workers directly handling blood.
D. An occupational therapist working with a client who has HIV may have some exposure risk, but it is significantly lower than that of a phlebotomist who handles blood samples.
Correct Answer is B
Explanation
A. Metabolic acidosis would be indicated by a low pH and a low HCO3, which is not present in this case since HCO3 is normal.
B. The pH of 7.32 indicates acidemia, and a PaCO2 of 50 mmHg suggests respiratory acidosis as the body is retaining carbon dioxide, contributing to the low pH. The HCO3 is normal, indicating that there is no metabolic compensation occurring.
C. Respiratory alkalosis would show a high pH and low PaCO2, which is not the case here.
D. Metabolic alkalosis would present with a high pH and elevated HCO3, which is also not present in these ABG results.
