Nutrition Final Exam
1. Which nutrient is classified as a micronutrient?
- A. minerals
- B. proteins
- C. alcohols
- D. carbohydrates
Correct answer: A
Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.
2. Which topic should be included in planning a secondary prevention project for the local retirement community?
- A. Safety measures in the home.
- B. Adult immunization program.
- C. Rehabilitation after surgery.
- D. Vision and hearing screening.
Correct answer: D
Rationale: In planning a secondary prevention project for the local retirement community, vision and hearing screening should be included. This is crucial as sensory impairments are common among older adults and early detection through screening can help in preventing further complications. Safety measures in the home, adult immunization programs, and rehabilitation after surgery are important but fall more under primary or tertiary prevention strategies rather than secondary prevention, which focuses on early detection and intervention to prevent the progression of health conditions.
3. A female UAP is assigned to take the vital signs of a client with pertussis for whom droplet precautions have been implemented. The UAP requests a change in assignment as she has not yet been fitted for a particulate filter mask. Which action should the nurse take?
- A. Advise the UAP to wear a standard face mask to take vital signs, and then get fitted for a filter mask before providing personal care
- B. Send the UAP to be fitted for a particulate filter mask immediately so she can provide care to this client
- C. Instruct the UAP that a standard mask is sufficient for the provision of care for the assigned client
- D. Before changing assignments, determine which staff members have fitted particulate filter masks
Correct answer: D
Rationale: The correct course of action for the nurse is to determine which staff members have already been fitted for particulate filter masks before changing assignments. This ensures safety and compliance with infection control protocols. Option A is incorrect as wearing a standard face mask before being fitted for a filter mask does not address compliance with droplet precautions. Option B is incorrect because the priority is to ensure all staff members have appropriate equipment before providing care. Option C is incorrect as a standard mask may not offer sufficient protection when dealing with clients under droplet precautions.
4. The healthcare provider is assessing a client who has a chest tube in place following a pneumothorax. Which finding should be reported to the healthcare provider immediately?
- A. Bubbling in the water seal chamber
- B. Drainage greater than 70 ml/hour
- C. Tidaling in the water seal chamber
- D. Absence of breath sounds on the affected side
Correct answer: D
Rationale: The absence of breath sounds on the affected side is a critical finding that may indicate a tension pneumothorax, a life-threatening condition requiring immediate intervention. This situation can lead to a shift of the mediastinum and impaired ventilation. Bubbling in the water seal chamber is an expected finding in a chest tube drainage system and indicates proper functioning. Drainage greater than 70 ml/hour is a concern but does not require immediate reporting unless it continues at a high rate or is associated with other symptoms. Tidaling in the water seal chamber is a normal fluctuation and indicates the chest tube system is patent and functioning correctly.
5. What role does a community health nurse play in disaster management?
- A. Providing direct patient care
- B. Conducting research on disaster impacts
- C. Coordinating emergency response efforts
- D. Developing new healthcare policies
Correct answer: C
Rationale: Community health nurses are primarily responsible for coordinating emergency response efforts during disasters. This involves organizing and implementing strategies to address the health needs of the community in crisis situations. Providing direct patient care (Choice A) is often carried out by other healthcare professionals such as doctors and paramedics during disasters. Conducting research on disaster impacts (Choice B) is important for understanding the effects of disasters but is not the primary role of a community health nurse. Developing new healthcare policies (Choice D) is typically the responsibility of policymakers and public health officials rather than community health nurses.
