1. What is the first step in the scientific method?

A. Conduct an experiment
B. Make an observation and ask a question
C. Formulate a hypothesis
D. Reach a consensus

Correct answer: B

Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.

2. Integrated management for childhood illness is the universal protocol of care endorsed by WHO and is used by different countries worldwide, including the Philippines. In any case that the nurse classifies the child and categorizes the signs and symptoms in the PINK category, you know that this means:

A. Urgent referral
B. Antibiotic Management
C. Home treatment
D. Outpatient treatment facility is needed

Correct answer: B

Rationale: When a child is classified under the PINK category in the Integrated Management of Childhood Illness (IMCI) guidelines, it signifies the need for antibiotic management. This category indicates severe signs and symptoms requiring immediate antibiotic treatment to address the underlying infection. Choices A, C, and D are incorrect because the PINK category specifically calls for urgent antibiotic management rather than urgent referral, home treatment, or outpatient treatment facility.

3. What is the primary function of antioxidants in the diet?

A. Provide energy
B. Support muscle growth
C. Neutralize free radicals
D. Increase blood sugar

Correct answer: C

Rationale: The primary function of antioxidants in the diet is to neutralize free radicals. Free radicals can cause cellular damage, leading to various chronic diseases. Antioxidants help combat this oxidative stress by neutralizing free radicals. Choices A, B, and D are incorrect because antioxidants do not provide energy, support muscle growth, or increase blood sugar; their main role is in combating oxidative stress.

4. Miss CEE is admitted for treatment of major depression. She appears withdrawn, disheveled, and states 'Nobody wants me'. What does the nurse most likely expect that Miss CEE is to be placed on?

A. Neuroleptics medication
B. Special diet
C. Suicide precaution
D. Anxiolytics medication

Correct answer: C

Rationale: Given Miss CEE's state of major depression and her expressed feelings of worthlessness ('Nobody wants me'), the nurse would most likely expect her to be placed on suicide precaution. This means that measures would be taken to ensure her safety and to prevent her from harming herself. While medications like neuroleptics (Choice A) and anxiolytics (Choice D) might be employed as part of her overall treatment, these medicines are primarily used for conditions like psychosis and anxiety respectively, not specifically for depression or suicidal ideation. A special diet (Choice B) may be part of a comprehensive treatment plan, but it is not as immediate or as directly related to her current emotional and psychological state as suicide precaution is.

5. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?

A. Spinach
B. Cantaloupe
C. Chicken
D. Lentils

Correct answer: C

Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.
