Nurse Raymond is handling a group of student nurses and he is teaching them about fluids and electrolytes. He is correct when he says that a substance moves from an area of higher concentration, this is:

Correct Answer: C

Rationale: Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. In the context of fluids and electrolytes, this process plays a crucial role in maintaining the balance of these substances in the body. Nurse Raymond is correct in stating that diffusion is the mechanism by which substances move down their concentration gradient. Osmosis involves the movement of water across a semipermeable membrane, filtration is the process of separating substances based on size through a filtering mechanism, and active transport requires energy to move substances against their concentration gradient.

Correct Answer: C

Rationale: Insulin absorption rates can vary depending on the injection site. The abdomen is one of the recommended sites for insulin injection due to its relatively rapid absorption rate compared to other sites such as the upper arm or thigh. Insulin injected into the abdomen is absorbed more quickly because of the larger blood supply in that area, leading to faster onset of action and better blood glucose control. This is why the nurse chose to administer the first insulin dose in the client's abdomen for optimal effectiveness.

Correct Answer: C

Rationale: When an adult is on a clear liquid diet, foods that are easy to digest and leave little residue in the gastrointestinal tract are recommended. Clear liquids include water, broth, fruit juices without pulp, and gelatin desserts like Jello. Jello is a good option because it is easily digestible, does not leave residue, and provides some calories and hydration. Milk, orange juice, and ice cream should be avoided on a clear liquid diet as they are not considered clear liquids and may not be as easily digestible.

Correct Answer: A

Rationale: Providing new information slowly and in small amounts to a confused individual, like Mr. Reyes, is important because confusion or delirium can be a defense mechanism against further stress. By giving information gradually, it allows the individual to better absorb and process the information without becoming overwhelmed, which can further exacerbate their confusion. This approach also helps reduce the risk of causing additional stress or agitation in the individual, thus promoting a more conducive environment for cognitive processing and understanding.

Correct Answer: C

Rationale: In the case of Mr. Dela Isla, who suffered a CVA, one of the most important discharge teachings would be drug compliance. Following a stroke, patients are often prescribed medications to help manage their condition and reduce the risk of further complications. It is crucial for Mr. Dela Isla to understand the importance of taking his medications as prescribed by his healthcare provider. Non-compliance with medication regimens can have serious consequences and may increase the likelihood of recurrent strokes or other health issues. Therefore, ensuring that Mr. Dela Isla understands the purpose of his medications, how to take them correctly, and the potential side effects is essential for his recovery and ongoing health management. While emergency numbers, relaxation techniques, and dietary prescriptions are important aspects of care, ensuring drug compliance is critical for the immediate and long-term well-being of a patient who has experienced a stroke.
