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. An elderly man is hospitalized with a diagnosis of malnutrition three months following his wife's death. What risk factor for malnutrition does this scenario illustrate?

• A. A history of chronic illness
• B. Depression or social isolation
• C. Age
• D. Impaired mobility

Correct answer: B

Rationale: This scenario illustrates depression or social isolation as a risk factor for malnutrition. After the death of his wife, the elderly man may have experienced depression or social isolation, which can lead to decreased food intake and poor nutritional status. Although age, chronic illness, and impaired mobility can also contribute to malnutrition, they are not the primary factors described in this scenario. The history of chronic illness (Choice A) and impaired mobility (Choice D) were not mentioned in the scenario, and while age (Choice C) is a factor, it's not the main factor depicted in this case.

3. A healthcare professional is reviewing the lab findings of a client who has Clostridium Difficile. Which of the following findings should indicate to the healthcare professional that the client is experiencing Fluid Volume Deficit?

• A. Hct 53%
• B. Potassium 3.5
• C. Sodium 145
• D. HbA1c 5

Correct answer: A

Rationale: An elevated hematocrit level (Hct 53%) indicates hemoconcentration, a sign of fluid volume deficit. Hct measures the percentage of red blood cells in the blood and increases when there is a decrease in plasma volume, as seen in fluid volume deficit. Choices B, C, and D do not directly relate to fluid volume status. Potassium and sodium levels are more indicative of electrolyte imbalances, while HbA1c reflects average blood sugar levels over the past 2-3 months and is not specific to fluid volume status.

4. A nurse is instructing teenage girls on the importance of adequate calcium intake throughout their life span to prevent complications. Which complication should the nurse include in the teaching?

• A. Goiter
• B. Osteoporosis
• C. Heart disease
• D. Dental caries

Correct answer: B

Rationale: The correct answer is B: Osteoporosis. Adequate calcium intake throughout life helps prevent osteoporosis, a condition characterized by weak and brittle bones, which is common in older adults. Goiter is caused by an iodine deficiency, not calcium. Heart disease is more related to factors like cholesterol and blood pressure. Dental caries are primarily influenced by oral hygiene and sugar intake, not just calcium.

5. What are the best food sources of magnesium?

• A. oils, bananas, and pork
• B. pizza, potatoes, and tomatoes
• C. milk, rice, and apples
• D. legumes, whole grains, and chocolate

Correct answer: D

Rationale: The correct answer is D: legumes, whole grains, and chocolate. These foods are rich sources of magnesium, an essential mineral that plays a role in over 300 biochemical reactions in the body. Choices A, B, and C do not contain as high levels of magnesium compared to legumes, whole grains, and chocolate.
