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. Symptoms of irritable bowel syndrome are most likely associated with disturbed defecation, bloating, and _____.

• A. rectal bleeding
• B. abdominal pain
• C. rectal fissures
• D. esophageal paralysis

Correct answer: B

Rationale: Abdominal pain is a common symptom of irritable bowel syndrome (IBS), along with bloating and changes in bowel habits. Rectal bleeding (choice A) is more commonly associated with conditions like inflammatory bowel disease or colorectal cancer. Rectal fissures (choice C) may cause rectal bleeding but are not typically considered a core symptom of IBS. Esophageal paralysis (choice D) is unrelated to the symptoms of IBS, which primarily affect the lower gastrointestinal tract.

3. In taking the client’s blood pressure, the nurse should position the client’s arm:

• A. At the level of the heart
• B. Slightly above the level of the heart
• C. At the 5th intercostals space midclavicular line
• D. Below the level of the heart

Correct answer: A

Rationale: Proper patient positioning is essential for maximizing lung expansion and promoting the drainage of secretions. Postural drainage techniques rely on gravity to help clear different lung segments, which is critical in preventing complications such as atelectasis or pneumonia in immobilized patients.

4. Causes of acute renal failure include:

• A. chronic renal failure
• B. uncontrolled diabetes mellitus
• C. recurrent urinary tract infections
• D. severe injury such as extensive burns

Correct answer: D

Rationale: The correct answer is D. Severe injuries, like extensive burns, can cause acute renal failure due to shock, reduced blood flow to the kidneys, and tissue damage. Choices A, B, and C are incorrect because chronic renal failure, uncontrolled diabetes mellitus, and recurrent urinary tract infections are more likely to contribute to chronic kidney disease rather than acute renal failure.

5. List 2 Dispensable amino acids

• A. Alanine
• B. Serine
• C. Glycine
• D. Proline

Correct answer: A

Rationale: Dispensable amino acids, such as alanine and serine, can be synthesized by the body and are not required to be obtained from the diet.
