1. Protein-energy malnutrition (PEM) may be responsible for the increased incidence of noma and necrotizing ulcerative gingivitis (NUG) because these conditions are associated with depressed immune responses caused by nutritional deficiencies.

A. Both the statement and the reason are correct and related
B. Both the statement and the reason are correct but are not related
C. The statement is correct, but the reason is not correct
D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: The corrected question highlights that protein-energy malnutrition weakens the immune system, making individuals more susceptible to conditions like noma and NUG, which are linked to compromised immunity. Choice A is correct because the statement and reason are both accurate and directly related. Protein-energy malnutrition does result in depressed immune responses, which can predispose individuals to noma and NUG. Choice B is incorrect because the statement and reason are indeed related. Choice C is incorrect as both the statement and reason are accurate. Choice D is also incorrect as the statement is correct and directly supports the reason provided.

2. Which risk factors increase the risk of atherosclerosis?

A. Exercise
B. Excessive sun exposure
C. Insufficient vaccinations
D. Smoking

Correct answer: D

Rationale: Smoking is a major risk factor for atherosclerosis. It significantly contributes to the buildup of plaque in the arteries and thereby increases the risk of cardiovascular diseases. On the other hand, exercise is generally beneficial for cardiovascular health and is not a risk factor for atherosclerosis. Excessive sun exposure and insufficient vaccinations have no established links to atherosclerosis, making them incorrect options for this question.

3. Each statement is true of rickets, except one. Which is the exception?

A. Rickets is being diagnosed more frequently in the United States.
B. Rickets is caused by vitamin C deficiency.
C. Tachetic deformities such as bow legs or knock-knees develop.
D. A narrow and distorted chest occurs.

Correct answer: B

Rationale: Rickets is caused by vitamin D deficiency, not vitamin C deficiency. It usually occurs in children who are 1 to 3 years old. The name rickets came from the word 'wrikken,' meaning 'to bend or twist.' Common manifestations of rickets include tachetic deformities like bow legs or knock-knees, a narrow and distorted chest, and failure of the epiphyses of bones to develop normally, resulting in twisted and warped bones. While the diagnosis of rickets may be increasing in the United States, it is not caused by a lack of vitamin C.

4. While a team effort is necessary in the operating room (OR) for efficient and quality patient care delivery, the number of people in the room should be limited for infection control purposes. Which roles comprise this team?

A. Surgeon, anesthesiologist, scrub nurse, radiologist, orderly
B. Surgeon, assistants, scrub nurse, circulating nurse, anesthesiologist
C. Surgeon, assistant surgeon, anesthesiologist, scrub nurse, pathologist
D. Surgeon, assistant surgeon, anesthesiologist, intern, scrub nurse

Correct answer: B

Rationale: The roles typically present in an operating room team include the surgeon, assistants (which may include an assistant surgeon), scrub nurse, circulating nurse, and anesthesiologist. These roles are directly involved in the operation and patient care. Choice B is correct. Choice A includes a radiologist and an orderly, who are not typically part of the immediate surgical team in the OR. Choice C includes a pathologist, who usually works in a laboratory outside of the OR. Choice D includes an intern, who may or may not be part of the team, depending on the specific circumstances and hospital policy. These explanations make choices A, C, and D incorrect.

5. Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?

A. Natural active immunity
B. Natural passive immunity
C. Artificial active immunity
D. Artificial passive immunity

Correct answer: B

Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.
