1. Churns chyme and has an environment of pH2; holds 4-6 cups of food:

Correct answer: A

Rationale: The stomach churns food into chyme and has a highly acidic environment (pH 2) to aid in the digestion of proteins and other nutrients.

2. Where should a nurse auscultate the apex beat?

Correct answer: A

Rationale: The correct location to auscultate the apex beat is at the fifth intercostal space, along the midclavicular line. This is where the apical impulse, also known as the point of maximal impulse (PMI), can be best heard. Choices B, C, and D are incorrect anatomical locations for auscultating the apex beat, which makes them incorrect choices. Auscultating at the correct location allows healthcare providers to assess the heart's function and detect any abnormalities in heart sounds, which is crucial for comprehensive patient care.

3. Cocaine is derived from the leaves of coca plant; the nurse knows that cocaine is classified as:

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

4. Which mineral is essential for wound healing?

Correct answer: C

Rationale: Zinc plays a critical role in wound healing due to its involvement in cell proliferation, immune function, and protein synthesis, all of which are essential for tissue repair.

5. What nutrition-related side effect is most likely to occur after head and neck surgery for cancer treatment?

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.
