Correct Answer: D

Rationale: Proteins play a diverse range of physiological roles in the body, such as providing resistance to disease, regulating fluid balance, and repairing tissues. However, they are not the primary source of energy for the body. Carbohydrates and fats typically fulfill this role. Therefore, choice D is the correct answer, as it is not a function that proteins perform. Conversely, choices A, B, and C are all physiological functions of proteins, making them incorrect responses to this particular question.

Correct Answer: A

Rationale: Proton pump inhibitors (PPIs) are a type of antisecretory drug that can cause nausea and vomiting by altering stomach acid production. These are common side effects associated with PPIs. Gastroparesis (B) is a condition that affects the stomach muscles and prevents proper stomach emptying; it is not a side effect of PPIs. Dumping syndrome (C) is a group of symptoms that can occur after having part of your stomach removed and is not a side effect of PPIs. While some people might experience flatulence (D) when taking PPIs, it is not as commonly associated with these drugs as the effects of nausea and vomiting.

Correct Answer: C

Rationale: The correct answer is C. Fat is crucial for the production of hormones, including reproductive hormones. Consuming too little fat can lead to hormonal imbalances, affecting fertility. Choices A, B, and D are incorrect. Constipation is more commonly associated with insufficient fiber intake, marasmus is severe malnutrition due to overall calorie deficiency, and diverticulitis is often related to low fiber intake and not specifically low fat consumption.

Correct Answer: B

Rationale: Before sharing information with a patient, it is essential to ask for their permission. This action respects the patient's autonomy and encourages their participation in the learning process. Asking for permission establishes a foundation of trust and partnership between the healthcare provider and the patient. Providing background knowledge (Choice A) is important, but it should come after receiving consent to share information. Removing personal protective equipment (Choice C) is not related to the communication process. Reminding the patient that you are the authority (Choice D) is inappropriate as it can undermine the patient's autonomy and hinder effective communication in a patient-centered care approach.

Correct Answer: C

Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.
