1. Which vitamin's recommended dietary allowance (RDA) is significantly increased during pregnancy?

• A. Folate
• B. Thiamine (B1)
• C. Riboflavin (B2)
• D. Niacin (B3)

Correct answer: A

Rationale: The correct answer is A: Folate. During pregnancy, the recommended dietary allowance (RDA) for folate is significantly increased to support fetal development and prevent neural tube defects and other congenital anomalies. Folate plays a crucial role in DNA synthesis and cell growth, making it essential for the rapidly dividing cells of the developing fetus. Thiamine (B1), Riboflavin (B2), and Niacin (B3) are important vitamins, but their RDAs do not undergo as significant an increase during pregnancy as folate's RDA does.

2. 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.

3. When is infertility said to exist?

• A. When a woman has no uterus
• B. When a woman has no children
• C. When a couple has been trying to conceive for 1 year without success
• D. When a couple has desired a child for 6 months

Correct answer: C

Rationale: Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Therefore, the correct answer is C. A, B, and D are incorrect. While having no uterus (choice A) may result in infertility, it is not the sole determining factor. Similarly, not having children (choice B) does not automatically indicate infertility. Lastly, the time frame of 6 months (choice D) is not sufficient to determine infertility; typically, a year of trying without success is required for such a diagnosis.

4. Which of the following nutrients provide energy?(Select ONE that does not apply.)

• A. Carbohydrates
• B. Fats
• C. Protein
• D. Water

Correct answer: D

Rationale: Carbohydrates, fats, and proteins are the three macronutrients that provide energy (calories) to the body. Carbohydrates are the body's primary source of energy, fats act as a secondary source when carbohydrate energy is exhausted, and proteins are used for energy when carbohydrate and fat sources are low. Choice D, Water, is essential for the body's functions, but it does not provide energy.

5. Medication for treating high blood cholesterol levels should not be used for most people unless:

• A. The patient has at least three major risk factors for coronary heart disease
• B. The patient has been experiencing symptoms of coronary heart disease for at least three months
• C. The patient's medical insurance covers prescription drugs
• D. Treatment with Therapeutic Lifestyle Changes (TLC) alone is unsuccessful after three months

Correct answer: D

Rationale: The correct answer is choice D because medication for high cholesterol is typically not considered unless Therapeutic Lifestyle Changes (TLC), which include diet and exercise, have not proven effective after a three-month period. This approach ensures that lifestyle modifications are given a fair chance to lower cholesterol levels before resorting to medication. Choice A is incorrect because the number of risk factors for coronary heart disease does not dictate when to begin medication; it is about the effectiveness of lifestyle changes. Choice B is incorrect as the duration of coronary heart disease symptoms does not determine when to start medication; the focus is on the response to TLC. Choice C is incorrect because the coverage of prescription drugs by the patient's insurance does not influence the medical decision to use medication for high cholesterol; it is based on medical necessity and effectiveness of prior interventions.
