1. AIDS enteropathy is most commonly manifested as _____.

• A. abdominal pain and rectal bleeding
• B. diarrhea and weight loss
• C. abdominal bloating and flatulence
• D. rectal fissures and constipation

Correct answer: B

Rationale: AIDS enteropathy typically presents as diarrhea and weight loss due to the impact of HIV on the gastrointestinal tract. While abdominal pain and rectal bleeding (Choice A), abdominal bloating and flatulence (Choice C), and rectal fissures and constipation (Choice D) can occur in some cases, the most common manifestations are diarrhea and weight loss.

2. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.

3. Select all that apply. You are interested in learning about the effect of eating diet soft drinks on your health. Your internet search leads you to a website with the ending .com, which tells you that diet soft drinks contain sugar alcohols that can cause harm. Which of the following actions are logical?

• A. notice if there are any ads on the page that suggest conflicts of interest
• B. read about consuming diet soft drinks in the dietary guidelines for Americans
• C. visit a more credible website and compare information
• D. all of the above

Correct answer: D

Rationale: Logical steps include evaluating the credibility of the website, reading official guidelines, comparing information from credible sources, and verifying the author's qualifications.

4. Much of the research investigating probiotics and intestinal illness has focused on the prevention and treatment of _____.

• A. irritable bowel syndrome
• B. Crohn's disease
• C. diverticulitis
• D. infectious diarrhea

Correct answer: D

Rationale: The correct answer is 'D: infectious diarrhea.' Research has extensively explored the use of probiotics in the prevention and treatment of infectious diarrhea. Probiotics can aid in restoring the balance of gut flora, thereby reducing symptoms. Choices A, B, and C are incorrect because while probiotics may have some benefits for these conditions, the primary focus of research in relation to probiotics and intestinal illness has been on infectious diarrhea.

5. Which of the following is reflected in an ECG due to hypokalemia?

• A. Tall T waves and Pathologic Q wave
• B. Widening QRS Complex and U wave
• C. None of the above
• D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.
