A nurse is admitting a client who was prescribed antibiotic therapy and now has a Clostridium difficile infection. Which of the following actions should the nurse take?

Correct Answer: A

Rationale: The correct answer is A: Disinfect equipment in the client's room daily. This is important for preventing the spread of Clostridium difficile, a highly contagious bacterium causing severe diarrhea. Disinfecting equipment helps eliminate the bacteria from the environment, reducing the risk of transmission to other individuals. Summary of other choices: B: Placing the client in a protective environment is unnecessary and not recommended for Clostridium difficile infection. C: While using alcohol hand sanitizer is important for hand hygiene, disinfecting equipment is more crucial in this case. D: Having the client wear a mask is not necessary for preventing the transmission of Clostridium difficile.

Correct Answer: A

Rationale: The correct answer is A: peristalsis. Peristalsis refers to the wave-like muscular contractions that propel food through the digestive tract. First, circular muscles contract behind the food bolus creating a narrowing, then longitudinal muscles contract ahead of the bolus, pushing it forward. This coordinated movement helps move food along the digestive tract efficiently. Deglutition (B) refers to the act of swallowing, not the movement of food through the digestive tract. Mass movements (C) refer to large, powerful contractions that occur in the colon to move feces. Segmental contractions (D) are localized contractions that mix and churn food in the intestines, not the primary mechanism for moving food along the digestive tract.

Correct Answer: A

Rationale: The correct answer is A because the coronary ligament attaches the liver to the diaphragm. This ligament forms part of the peritoneal ligaments that secure the liver to the diaphragm, supporting its position in the abdominal cavity. The other choices are incorrect because: B) The liver is attached to the anterior abdominal wall by the falciform ligament, not the coronary ligament. C) The colon is attached to the posterior body wall by the mesocolon, not the coronary ligament. D) The lesser curvature of the stomach and proximal end of the duodenum are attached to the liver and diaphragm by the lesser omentum, not the coronary ligament.

Correct Answer: C

Rationale: The correct answer is C: amylase, maltose. Amylase is the digestive enzyme present in saliva that breaks down starch into maltose. When you suck on bread, the amylase in saliva starts breaking down the starch molecules into maltose, which is a sugar that tastes sweet. Option A is incorrect because amylase breaks down starch into maltose, not glucose. Option B is incorrect because pepsin is a stomach enzyme that breaks down proteins, not starch. Option D is incorrect because maltase is an enzyme in the small intestine that breaks down maltose into glucose, not the enzyme present in saliva.

Correct Answer: B

Rationale: The correct answer is B: heartburn. This is because heartburn is the common term for the painful or burning sensation in the chest caused by acid reflux in the esophagus. A peptic ulcer (A) and a duodenal ulcer (D) are sores in the stomach or small intestine, not specific to the chest area. Angina (C) is chest pain related to heart issues, not specifically caused by acid reflux. Therefore, B is the correct answer.
