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 C

Explanation

A. After intravesical therapy, there may be recommendations to avoid sexual activity for a certain period (often 24 hours) to prevent exposure to the medication by a partner. However, the specifics can vary based on the medication used. Twelve hours might not be sufficient depending on the protocol.
B. Self-catheterization is not routinely required unless there is a specific reason (e.g., urinary retention or difficulty voiding). This statement is not relevant to the therapy itself.
C. Urinating in a sitting position can help ensure more complete emptying of the bladder and can be safer, particularly for women. It also may minimize contact with any residual medication in the bladder, which can be a consideration post-infusion.
D. Patients are usually advised to avoid excessive fluid intake immediately before the infusion to prevent bladder distention during the treatment.

A. A serum prolactin level B. An endometrial biopsy C. A Papanicolaou test D. A vaginal ultrasound

Correct Answer is C

Explanation

A. This test is used to measure the level of prolactin, a hormone that stimulates milk production. It is not relevant for cervical cancer screening.
B. This test involves taking a sample of tissue from the lining of the uterus. It is used to diagnose endometrial cancer, not cervical cancer.
C. The Papanicolaou test, commonly known as a Pap smear, is the standard screening test for cervical cancer. It involves collecting cells from the cervix to detect any precancerous changes or cervical cancer itself. This is the correct answer, as it directly relates to cervical cancer screening.
D. This test uses sound waves to create images of the vagina and cervix. It can be used to evaluate the cervix for abnormalities, but it is not as sensitive as a Pap test for detecting cervical cancer.
