Answer and Explanation

The Correct Answer is A

Based on the given arterial blood gas results, the patient's pH is elevated, indicating alkalosis. The PaCO2 level is decreased, which suggests respiratory compensation. The bicarbonate (HCO3-) level is within the normal range. Therefore, the interpretation of the arterial blood gas results is respiratory alkalosis.

Correct Answer is B

Explanation

Abdominal discomfort an hour after a meal is a common symptom of a gastric ulcer because the stomach is where food is initially processed, and stomach acid is most concentrated. In contrast, duodenal ulcers typically cause pain 2-3 hours after meals, as food moves out of the stomach and into the duodenum, where it encounters duodenal acid.

A positive stool occult blood test is a non-specific finding that can be caused by many gastrointestinal conditions, including peptic ulcers. It does not indicate the location of the ulcer.

The number of ulcers the client has had in the past does not indicate the location of the current ulcer.

Normal hemoglobin and hematocrit levels do not provide information about the location of the ulcer.

A. increase the eﬀectiveness of the drug by taking it with cranberry juice to acidify the urine. B. take two of the pills a day for 5 days and reserve the rest of the pills to take it the symptoms reappear. C. take the antibiotic for the full 7 days, even if symptoms improve in a few days. D. return to the clinic in 3 days so that a urine culture can be done to evaluate the eﬀectiveness of the drug.

Correct Answer is C

Explanation

The nurse's instruction to the patient is to take the antibiotic for the full 7 days, even if symptoms improve in a few days. This is because the full course of antibiotics is needed to eliminate the bacteria causing the UTI, even if the patient starts to feel better before the end of the treatment course. Failure to complete the full course of antibiotics can lead to the development of antibiotic resistance and the recurrence of the infection. The other options are not appropriate or eﬀective measures for managing a UTI with antibiotics.
