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. The two members of the health care team who work closely to monitor drug-nutrient interactions are the:

A. physician and nurse
B. physician and pharmacist
C. nurse and clinical dietitian
D. clinical dietitian and pharmacist

Correct answer: D

Rationale: The correct answer is D: clinical dietitian and pharmacist. Clinical dietitians and pharmacists work closely together to monitor and manage drug-nutrient interactions. While physicians and nurses play essential roles in patient care, they are not typically the primary professionals involved in monitoring drug-nutrient interactions. Therefore, choices A, B, and C are incorrect.

3. A nurse is providing teaching to a group of adult athletes about preventing the effects of dehydration on the body. Which of the following manifestations should the nurse include in the teaching?

A. Impaired motor control
B. Drop in body temperature during exercise
C. Increase in appetite
D. Decreased resting heart rate

Correct answer: A

Rationale: Dehydration can lead to impaired motor control due to electrolyte imbalances affecting muscle function. Choices B, C, and D are incorrect. Dehydration typically causes an increase in body temperature during exercise, not a drop. Dehydration is more likely to suppress appetite, leading to a decrease rather than an increase in appetite. Also, dehydration often results in an increased heart rate rather than a decreased resting heart rate.

4. The correct temperature to store vaccines in a refrigerator is:

A. between -4 deg C and +8 deg C
B. between 2 deg C and +8 deg C
C. between -8 deg C and 0 deg C
D. between -8 deg C and +4 deg C

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. Which monosaccharide is the most sweet?

A. Glucose
B. Dextrose
C. Fructose
D. Sucrose

Correct answer: C

Rationale: Fructose is the sweetest of the monosaccharides. Note that glucose and dextrose are the same, and sucrose is a disaccharide, not a monosaccharide.
