A nurse is teaching a client who has glaucoma and is to start taking timolol. Which of the following information should the nurse include?

Choice A Reason:

Suctioning secretions from the endotracheal tube is a common intervention for high-pressure alarms, which indicate an obstruction in the airway. However, a low-pressure alarm typically signals a disconnection or leak in the ventilator system, not an obstruction.

Choice B Reason:

Checking the ventilator tubing connections is the appropriate response to a low-pressure alarm. This alarm usually indicates a disconnection or leak in the ventilator circuit, which can compromise the delivery of adequate ventilation to the patient. Ensuring all connections are secure is the first step in troubleshooting this issue.

Choice C Reason:

Administering intravenous sedation and analgesia is not directly related to addressing a low-pressure ventilator alarm. While sedation may be necessary for patient comfort and to prevent agitation, it does not resolve the underlying issue of a disconnection or leak in the ventilator system.

Choice D Reason:

Reassuring the client and instructing them not to bite on the tube is more relevant to high-pressure alarms, where patient actions such as biting the tube can cause increased airway resistance. It does not address the cause of a low-pressure alarm, which is typically due to a disconnection or leak.

Choice A Reason

“Your provider will use stool from your digital rectal examination to perform the test.” This statement is incorrect. For fecal occult blood testing, stool samples are typically collected at home using a special kit provided by the healthcare provider. The samples are then sent to a lab for analysis. Using stool from a digital rectal examination is not the standard procedure for FOBT.

Choice B Reason

“Your provider will prescribe a stimulant laxative prior to the procedure to evacuate the bowel.” This statement is incorrect. Stimulant laxatives are not typically prescribed before an FOBT. The test requires a small sample of stool, and using a laxative could interfere with the results. Patients are usually advised to follow specific dietary and medication guidelines to avoid false positives or negatives.

Choice C Reason

“You should begin annual fecal occult blood testing for colorectal cancer screening at 40 years old.” This statement is incorrect. Current guidelines recommend starting colorectal cancer screening, including FOBT, at age 45 for individuals at average risk. Screening may start earlier for those with a higher risk, such as a family history of colorectal cancer.

Choice D Reason

“You should avoid taking corticosteroids prior to testing.” This is the correct statement. Corticosteroids can cause gastrointestinal irritation and bleeding, which may lead to false-positive results in fecal occult blood tests. Therefore, it is important to avoid these medications before testing.
