respiratory alkalosis.

metabolic alkalosis.

respiratory acidosis.

metabolic acidosis.

Answer and Explanation

The Correct Answer is A

A.   The elevated pH and decreased PaCO2 indicate that the respiratory system is causing alkalosis, typically due to hyperventilation (excessive breathing).
B.   Metabolic alkalosis would be indicated by a high pH with a normal or high HCO3. Since the HCO3 level is normal and the PaCO2 is low, this does not fit the picture of metabolic alkalosis.
C.   Respiratory acidosis would be characterized by a low pH and an elevated PaCO2 due to inadequate ventilation and accumulation of carbon dioxide. Here, the pH is high, and the PaCO2 is low.
D.   Metabolic acidosis would be indicated by a low pH with a low HCO3. In this case, the pH is high, and the HCO3 is normal.

Correct Answer is A

Explanation

A. Ascites is a condition where excess fluid accumulates in the abdominal cavity. It is a common finding in advanced-stage ovarian cancer as the cancer can spread to the abdominal organs and lymph nodes, leading to fluid buildup.
B. Chest pressure is not a typical symptom of advanced-stage ovarian cancer. It might be associated with other conditions, such as heart disease or lung problems.
C. Painful urination is not a common symptom of advanced-stage ovarian cancer. It might be associated with other conditions, such as urinary tract infections or bladder problems.
D. Excessive flatus is not a typical symptom of advanced-stage ovarian cancer. It might be associated with other gastrointestinal conditions.

A. "I should not exercise if I develop a leg ulcer." B. "I should buy my shoes in the afternoon." C. "I should dangle my legs when sitting." D. "I must wear compression stockings at all times."

Correct Answer is D

Explanation

A. While it's true that ulcers can be a serious complication of PAD and require careful management, exercise is generally encouraged in patients with PAD as long as it is safe and supervised. Patients should consult their healthcare provider about appropriate exercise, but not exercising altogether can worsen their condition.
B. Buying shoes in the afternoon is advisable because feet can swell throughout the day. It helps ensure a better fit and reduces the risk of blisters or skin breakdown, which is particularly important for clients with PAD.
C. This statement is generally correct, as dangling the legs can help improve circulation in some cases. Clients with PAD often experience relief when their legs are in a dependent position, as it may help increase blood flow to the extremities. However, they should also be encouraged to avoid prolonged periods of sitting.
D. This statement may indicate a misunderstanding. Compression stockings are typically used for venous issues rather than arterial diseases like PAD. In patients with PAD, wearing compression stockings may not be appropriate and could potentially compromise arterial blood flow.
