1. The nurse is correct in performing suctioning when she applies the suction intermittently during:
- A. Insertion of the suction catheter
- B. Withdrawing of the suction catheter
- C. both insertion and withdrawing of the suction catheter
- D. When the suction catheter tip reaches the bifurcation of the trachea
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
2. What nutrition-related side effect is most likely to occur after head and neck surgery for cancer treatment?
- A. Aspiration
- B. Acid reflux
- C. Dumping syndrome
- D. Diarrhea
Correct answer: A
Rationale: The most likely nutrition-related side effect after head and neck surgery for cancer treatment is aspiration. This is due to changes in swallowing mechanics, which can cause food or liquids to be inhaled into the lungs. While acid reflux, dumping syndrome, and diarrhea are potential side effects related to nutrition, they are not as directly connected to head and neck surgery. Acid reflux is more often related to issues with the lower esophageal sphincter, dumping syndrome is typically a complication of gastric surgery, and diarrhea can have various causes, including certain medications or gastrointestinal illnesses.
3. Macronutrients include each of the following except one. Which one is the exception?
- A. Fat
- B. Polyunsaturated fatty acids
- C. Carbohydrate
- D. Protein
Correct answer: D
Rationale: Macronutrients are nutrients required by the body in large amounts to provide energy and include carbohydrates, fats, and proteins. While protein is essential for the body, it is not classified as a macronutrient. Proteins are made up of amino acids and serve various functions in the body, such as building and repairing tissues, but they are not a direct energy source like carbohydrates and fats. Therefore, protein is the exception among the listed options, making it the correct answer. Choice A, Fat, Choice B, Polyunsaturated fatty acids, and Choice C, Carbohydrate, are all examples of macronutrients that provide energy and support various bodily functions.
4. What stimulates bile secretion from the liver to the small intestine?
- A. Pepsin
- B. Salivary Amylase
- C. CCK
- D. Secretin
Correct answer: CCK
Rationale: Cholecystokinin (CCK) is the hormone that stimulates the release of bile from the gallbladder into the small intestine, aiding in fat digestion. Pepsin is an enzyme in the stomach that breaks down proteins into smaller peptides, not involved in bile secretion. Salivary Amylase is an enzyme in saliva that initiates starch digestion in the mouth, not related to bile secretion. Secretin is a hormone that regulates the release of gastric juice in the stomach and triggers the pancreas to neutralize stomach acid in the small intestine, but it does not stimulate bile secretion.
5. During operation, who manages the lighting, noise, temperature and other factors in the operating room suite?
- A. Nurse Supervisor
- B. Surgeon
- C. Circulating Nurse
- D. Scrub Nurse
Correct answer: C: Circulating Nurse
Rationale: In an operating room, the circulating nurse is responsible for managing environmental factors such as lighting, noise, and temperature. This role includes ensuring the comfort and safety of the patient, as well as the efficiency of the team. While the Nurse Supervisor, Surgeon, and Scrub Nurse also have crucial roles during an operation, they do not directly manage the environmental conditions of the operating room. The rationale provided does not directly address the question asked, and appears to relate more to the broader role of nursing in patient care.
