1. Which is NOT a characteristic or function of lipids?

Correct answer: D

Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.

2. How many grams of protein per day are recommended for a person weighing 150 lbs?

Correct answer: D

Rationale: The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. To convert pounds to kilograms, divide the weight in pounds by 2.2. Therefore, a 150 lb person weighs approximately 68 kg (150 / 2.2 = 68). Multiplying 68 kg by 0.8 grams gives us 54 grams of protein per day. Choices A, B, and C are incorrect as they do not align with the RDA calculation based on body weight.

3. When can a patient's medical record become a potential issue for the doctor or nurse?

Correct answer: D

Rationale: The correct answer is D. A medical record becomes a potential issue for a doctor or a nurse when it is inaccurate, incomplete, or inadequate. This is because a medical record is a key tool for healthcare professionals to track a patient's history, treatment, and progress. If the record is not accurate or complete, it can lead to misdiagnosis, incorrect treatment, or other potential problems in patient care. While missing records (Choice C) could be a problem, they do not directly implicate the doctor or nurse in the same way that inaccurate or inadequate records do. An extensive record (Choice A) or a record being subpoenaed in court (Choice B) are not inherently problematic for healthcare professionals and do not necessarily reflect negatively on their work.

4. Diego is undergoing blood transfusion of the first unit. The earliest signs of transfusion reactions are:

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.

5. Which condition is an example of a potential cause of gastritis?

Correct answer: A

Rationale: Bile reflux is a potential cause of gastritis as it can irritate the stomach lining when bile backs up into the stomach. Choices B, C, and D do not directly cause gastritis. Low salt intake is not a common cause of gastritis. Hypophosphatasia is a rare genetic disorder affecting bone development, not the stomach. Gallstones, while related to the gallbladder, are not a direct cause of gastritis.
