Choice A rationale

Placing the client in a supine position is not recommended during nasogastric tube insertion. The client should be in an upright position, such as sitting up or in a high Fowler’s position, to facilitate the passage of the tube and reduce the risk of aspiration.

Choice B rationale

Withdrawing the tube if the client gags during insertion is not the correct action. Gagging is a common reaction during nasogastric tube insertion. The nurse should pause and allow the client to rest and swallow. The tube should only be withdrawn if the client is unable to breathe or is extremely distressed.

Choice C rationale

Instructing the client to place his chin to his chest and swallow can facilitate the passage of the tube through the esophagus. This position closes off the trachea and opens the esophagus, reducing the risk of the tube entering the trachea.

Choice D rationale

Measuring the tube for insertion from the tip of the nose to the umbilicus is not the correct method. The correct measurement is from the tip of the nose to the earlobe and then down to the xiphoid process of the sternum.

Choice A rationale

Requesting the providers to initiate antibiotic therapy for every patient on the unit is not the most appropriate action. Antibiotics should only be used when there is a confirmed bacterial infection. Overuse of antibiotics can lead to antibiotic resistance and can potentially trigger C. difficile infection due to disruption of normal gut flora.

Choice B rationale

While performing hand hygiene with an alcohol-based agent is important in general infection control, it is not the most effective measure against C. difficile.

C. difficile spores are resistant to destruction by alcohol-based hand rubs. Therefore, hand hygiene for C. difficile should involve washing with soap and water.

Choice C rationale

Obtaining stool cultures from all patients on the nursing unit is not the most appropriate action. Stool cultures should be obtained from patients who are symptomatic. Testing asymptomatic patients can lead to false positives and unnecessary treatment.

Choice D rationale

Placing all patients who have symptoms on contact precautions is the correct answer. Contact precautions, including the use of gloves and gowns, can prevent the spread of C. difficile. This is because C. difficile is spread via the fecal-oral route, and its spores can survive on surfaces for long periods.
