The physical environment and traffic control measures of the operating room are designed primarily to:

Allow smooth functioning of the operating room team.

Ensure efficient completion of surgical procedures.

Prevent transmission of infection.

Protect the privacy of the patient.

Answer and Explanation

The Correct Answer is C

The operating room is a sterile environment, and it is critical to maintain a clean and controlled environment to reduce the risk of infection to the patient. The measures taken include maintaining positive air pressure, controlling temperature and humidity, filtering the air, using sterile surgical instruments, and limiting traffic in and out of the operating room. These measures help to prevent the spread of infectious agents that may be present in the operating room. While the other options (a, b, and d) may also be important considerations in the design of the operating room, preventing transmission of infection is the primary goal.

Correct Answer is A

Explanation

The plan of care for a patient with hypothermia and ﬂuid volume excess would typically include measures to increase the patient's body temperature and decrease their ﬂuid volume. Therefore, option a (ﬂuid restriction) would be appropriate for this patient.

Options b (administration of hypotonic IV ﬂuids) and d (administration of ion-exchange resin) would not be appropriate because they would increase the patient's ﬂuid volume rather than decrease it.

Option c (placement of an indwelling urinary catheter) may be appropriate to closely monitor the patient's urine output, which is an important indicator of their ﬂuid status. However, this alone would not be sufficient to manage the patient's hypothermia and ﬂuid volume excess.

A. Decreasing serum sodium B. Decreasing blood glucose C. Decreasing serum potassium D. Increasing urinary output

Correct Answer is D

Explanation

One of the hallmarks of adrenal insufficiency is dehydration and decreased urinary output, which can lead to electrolyte imbalances such as hyperkalemia and hyponatremia. As treatment begins to take eﬀect, the patient's ﬂuid and electrolyte balance should improve, leading to an increase in urinary output. Acute adrenal insufficiency, also known as the Addisonian crisis, is a life-threatening condition caused by a sudden decrease in cortisol and aldosterone hormones. Treatment usually involves the administration of intravenous glucocorticoids and mineralocorticoids to replace the deficient hormones.
Decreasing serum sodium (a) and decreasing blood glucose (b) are not signs of improvement but rather indicative of continued adrenal insufficiency. Decreasing serum potassium (c) is also not a sign of improvement as it could indicate that the patient is developing hyperkalemia, which is a potential complication of adrenal crisis.
