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. Each statement is true of vitamin K, except one. Which is the exception?

• A. Vitamin K is produced in the gut.
• B. Vitamin K functions as a catalyst for the synthesis of blood-clotting factors.
• C. Vitamin K maintains prothrombin levels.
• D. Vitamin K absorption increases with high levels of vitamin E supplementation.

Correct answer: D

Rationale: The correct answer is D. Vitamin K absorption decreases with high levels of vitamin E supplementation because in larger amounts, vitamin E acts as an anticoagulant. Vitamin K is not produced in the gut but can be obtained from food sources or supplements. Vitamin K is essential for the synthesis of blood-clotting factors and is crucial in maintaining prothrombin levels, which is vital for proper blood clotting. The incorrect choice, D, is misleading as high levels of vitamin E supplementation hinder vitamin K absorption due to its anticoagulant properties. Dental hygienists should be aware of the importance of vitamin K in blood clotting, especially when treating patients who are on anticoagulant medications for conditions like stroke prevention.

3. On the study “effects of effective nurse-patient communication in decreasing anxiety of post operative patients” What is the Independent variable?

• A. Effective Nurse-patient communication
• B. Communication
• C. Decreasing Anxiety
• D. Post operative patient

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. A nurse is providing teaching to a client with gastroesophageal reflux. Which of the following statements by the client indicates a need for further teaching?

• A. I should elevate the head of my bed while sleeping.
• B. I drink no more than 4 cups of coffee a day.
• C. I take my time when I am eating.
• D. I avoid foods and drinks made with chocolate.

Correct answer: B

Rationale: The correct answer is B: 'I drink no more than 4 cups of coffee a day.' Excessive coffee consumption can aggravate gastroesophageal reflux due to its acidic nature. Choices A, C, and D are all appropriate self-care measures for managing gastroesophageal reflux. Elevating the head of the bed while sleeping helps prevent acid reflux, eating slowly can reduce reflux episodes, and avoiding trigger foods like chocolate can help alleviate symptoms.

5. A client with hypertension is being educated by a nurse about a heart-healthy diet. Which of the following statements indicates that the client understands the teaching?

• A. I will get 15% of my total daily calories from saturated fats.
• B. I will decrease the potassium in my diet.
• C. I will limit my daily sodium intake to 3 grams.
• D. I will eat five 8-ounce servings of fruit daily.

Correct answer: C

Rationale: The correct answer is C. Limiting daily sodium intake to 3 grams is crucial in managing blood pressure and is a fundamental aspect of a heart-healthy diet. High sodium intake can contribute to hypertension and cardiovascular issues. Choices A, B, and D are incorrect because getting 15% of daily calories from saturated fats, decreasing potassium intake, and eating five servings of fruit do not directly address the management of hypertension through sodium restriction.
