1. Which nutrient deficiency produces microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia?

• A. Zinc
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: B

Rationale: A deficiency in iron can lead to various symptoms, such as microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia. Iron-deficiency anemia may be caused by inadequate dietary intake; accelerated demand or losses; and inadequate absorption secondary to diarrhea, decreased acid secretions, or antacid therapy. Iron deficiency is frequently the result of postnatal feeding practices and has a serious impact on growth and mental and psychomotor development in infants and children. Choices A, C, and D are incorrect as zinc deficiency typically presents with symptoms like impaired wound healing, taste abnormalities, and hair loss; sodium deficiency can lead to symptoms such as muscle cramps, dizziness, and confusion; and potassium deficiency may cause muscle weakness, fatigue, and abnormal heart rhythms.

2. Which food is a reliable source of B12 for a pregnant vegan client?

• A. Soybeans
• B. Algae
• C. Fortified soy milk
• D. Sea vegetables

Correct answer: C

Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.

3. A Hazard Analysis and Critical Control Points (HACCP) program would address which element of food service?

• A. cleaning and disinfecting of utensils
• B. developing healthy menus
• C. controlling patient calorie intake
• D. prescribing diets for patients with swallowing problems

Correct answer: A

Rationale: The correct answer is A. Hazard Analysis and Critical Control Points (HACCP) programs are designed to ensure food safety by identifying and controlling potential hazards. This includes addressing the cleaning and disinfecting of utensils to prevent contamination and maintain safe food handling practices. Choices B, C, and D are incorrect because HACCP primarily focuses on preventing food safety hazards rather than developing menus, controlling calorie intake, or prescribing diets for specific medical conditions.

4. What is the most effective way to limit the number of microorganisms in the hospital?

• A. Using strict aseptic technique in all procedures
• B. Wearing a mask and gown when caring for all patients with communicable diseases
• C. Sterilizing all instruments
• D. Handwashing

Correct answer: A

Rationale: The most effective way to limit the number of microorganisms in the hospital is by using strict aseptic technique in all procedures. This approach ensures that the risk of introducing harmful microorganisms into the hospital environment or patients is minimized. Choice B, wearing a mask and gown when caring for patients with communicable diseases, is important but not as comprehensive as using aseptic technique in all procedures. Sterilizing all instruments (Choice C) is crucial for preventing infections but may not address all avenues of microorganism transmission. Handwashing (Choice D) is a fundamental practice in infection control but alone may not be as effective as utilizing aseptic techniques in all procedures to limit microorganisms in the hospital.

5. Why is atherosclerosis dangerous to arterial function?

• A. It diminishes central circulation
• B. It causes decreased blood pressure on artery walls
• C. It narrows the arterial lumen so a clot can easily block it
• D. It increases arterial elasticity

Correct answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
