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. If a child has two or more pink signs, you would classify the child as having:

A. No disease
B. Mild form of disease
C. Urgent Referral
D. Very severe disease

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

3. In order to establish and maintain successful breastfeeding, which practice should a lactating mother try to follow?

A. Initiate breastfeeding within 24 hours of birth
B. Breastfeed on a schedule of every 2 to 3 hours
C. Give a pacifier to an infant between feedings
D. Find a breastfeeding support group to troubleshoot problems

Correct answer: D

Rationale: The correct answer is D. Finding a breastfeeding support group is crucial for a lactating mother to establish and maintain successful breastfeeding. This group can offer valuable advice, tips, and encouragement, helping the mother troubleshoot any issues that may arise during breastfeeding. Choices A, B, and C are incorrect because breastfeeding is a natural process that should not be overly scheduled, and giving a pacifier between feedings can interfere with establishing proper breastfeeding techniques.

4. Which of the following statements is correct about MyPlate?

A. Canned fruit can be considered part of the fruit group
B. Soymilk is considered part of the dairy group
C. Beans and peas are considered part of both the protein group and the vegetable group
D. Cream cheese and butter are not part of the dairy group

Correct answer: C

Rationale: According to the MyPlate guide, beans and peas are classified as part of both the protein and vegetable groups due to their high protein content and the nutrients they share with vegetables. This makes Choice C correct. Choice A is incorrect as canned fruit can be part of the fruit group if it's canned in water or 100% fruit juice. Soymilk is considered part of the dairy group, making Choice B incorrect. While cream cheese and butter are dairy products, they are not part of the dairy group on MyPlate because they contain little to no calcium, making Choice D incorrect.
