2. Which of the four phases of emergency management is defined as 'sustained action that reduces or eliminates long-term risk to people and property from natural hazards and their effects'?

A. Recovery
B. Mitigation
C. Response
D. Preparedness

Correct answer: B

Rationale: The correct answer is B, 'Mitigation.' Mitigation is the phase of emergency management that focuses on sustained actions aimed at reducing or eliminating long-term risks to people and property from natural hazards. Recovery (A) involves restoring and rebuilding infrastructure, housing, and services after a disaster. Response (C) deals with immediate actions taken to save lives and prevent further damage during a disaster. Preparedness (D) involves planning, training, and equipping organizations and communities to effectively respond to emergencies.

3. Which mineral-containing amino acids help to form the shape of proteins?

A. phosphorus
B. sulfur
C. selenium
D. iron

Correct answer: B

Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.

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.
