Correct Answer: B

Rationale: The stomach is the organ responsible for the mechanical and chemical digestion of food. When food enters the stomach, it is mixed with stomach acid and enzymes to break down the food into smaller particles. This process helps prepare the food for further digestion and absorption of nutrients. The stomach also plays a key role in the absorption of some nutrients, such as certain vitamins and minerals. Additionally, the stomach's muscular contractions help mix the food with digestive enzymes and propel the partially digested food into the small intestine for further processing and absorption. The liver, pancreas, and large intestine have vital functions in the digestive system, but the stomach is the primary organ responsible for the initial digestion and absorption of nutrients.

Correct Answer: D

Rationale: The priority restriction that should be emphasized when the patient is discharged from the hospital is the lifting of objects not more than 10 lbs. This is important to prevent any strain on the body, especially if the patient is still recovering or weak from their hospitalization. Lifting heavy objects can lead to complications, injuries, or setbacks in the recovery process. It is essential for the patient to follow this restriction to promote healing and avoid any further health issues.

Correct Answer: B

Rationale: The stomach is responsible for producing hydrochloric acid and intrinsic factor. Hydrochloric acid helps in the breakdown of proteins during digestion, while intrinsic factor aids in the absorption of vitamin B12 in the small intestine. These two components are crucial for the proper functioning of the digestive system, particularly in breaking down food and absorbing essential nutrients. The liver is involved in bile production, the pancreas in the production of digestive enzymes, and the small intestine in nutrient absorption, but the specific functions related to hydrochloric acid and intrinsic factor are primarily attributed to the stomach.

Correct Answer: A

Rationale: Amitriptyline, being a tricyclic antidepressant, commonly causes anticholinergic side effects. These effects include dry mouth, constipation, blurred vision, urinary retention, and confusion. Anticholinergic effects are due to the drug's inhibition of the neurotransmitter acetylcholine, which can lead to the symptoms mentioned above. These side effects can be bothersome for patients taking amitriptyline, but they are generally manageable and often improve over time as the body adjusts to the medication. In the case of bulimia treatment, the benefits of using amitriptyline to address the underlying psychological issues often outweigh the side effects.

Correct Answer: B

Rationale: When a woman in active labor experiences persistent fetal malposition, such as a transverse lie presentation, assisting the mother into a hands-and-knees position is a nursing intervention to prioritize. This position can help encourage the fetus to rotate into a more favorable position for delivery, such as a head-down position. By placing the mother in a hands-and-knees position, gravity can assist in shifting the fetus to the correct position. This intervention is non-invasive and can be effective in promoting the progress of labor and avoiding the need for more invasive interventions like instrumental delivery or cesarean section. However, if the fetus does not rotate or if there are signs of fetal distress, further interventions may be necessary.
