An older patient exhibits a shuffling gait, lack of facial expression, and tremors at rest. The nurse will expect the provider to order which medication for this patient?

A. Blood cultures will need to be drawn.

Blood cultures are not typically used for diagnosing H. pylori infection. Instead, specific blood tests, such as serology or antibody tests, may be employed to detect antibodies against H. pylori.

B. A biopsy of the stomach will be done.

While a biopsy may be taken during an upper endoscopy to examine the stomach lining for ulcers and H. pylori infection, it is not the primary method for detecting the presence of H. pylori. The biopsy may be used for confirming the infection and assessing the severity of damage.

C. A breath test will be performed.

This is the correct choice. The breath test is a common and non-invasive method used to detect the presence of H. pylori. The patient drinks a solution containing a substance that H. pylori can break down, and the detection of carbon dioxide in the patient's breath indicates the presence of the bacteria.

D. Computerized scanning will identify if H. pylori is present.

Computerized scanning, such as computed tomography (CT) scans, is not a primary method for detecting H. pylori. Imaging studies are not typically used for H. pylori diagnosis, and the methods mentioned earlier, like breath tests and endoscopy, are more commonly employed.

A. Hypertension
Hypertension is not a specific concern related to the use of bisacodyl. Bisacodyl is a laxative, and high blood pressure is not typically considered a contraindication for its use.

B. Anemia
Anemia is not a specific concern related to the use of bisacodyl. The primary focus before administering bisacodyl is to assess for signs or symptoms of appendicitis, as its use is contraindicated in cases of suspected appendicitis.

C. Allergy to penicillin
Allergy to penicillin is not relevant in the context of administering bisacodyl. These are unrelated medications with different mechanisms of action, and allergy to penicillin does not impact the administration of bisacodyl.

D. Appendicitis
This is the correct choice. Before administering bisacodyl, it is crucial to assess the patient for signs or symptoms of appendicitis. The use of bisacodyl is contraindicated in cases of suspected appendicitis, as it may stimulate bowel activity and worsen the condition.
