1. A healthy 68-year-old client asks the practical nurse (PN) whether they should take the pneumococcal vaccine. Which statement should the PN offer to the client that provides the most accurate information about this vaccine?
- A. The vaccine is given annually before the flu season to those older than 50 years.
- B. The immunization is recommended for children younger than 2 years old and all adults 65 years or older.
- C. The vaccine is for all ages and is given primarily to those traveling overseas to areas of infection.
- D. The vaccine will prevent the occurrence of pneumococcal pneumonia for up to 5 years.
Correct answer: B
Rationale: The correct answer is B because it is usually recommended that children younger than 2 years old and adults 65 years or older get vaccinated against pneumococcal disease. This is because these age groups are more susceptible to severe complications from the infection. While the vaccine may be recommended for certain individuals with specific medical conditions at any age, the primary target groups are as mentioned in option B. Option A is incorrect as the pneumococcal vaccine is not given annually like the flu vaccine. Option C is incorrect because the vaccine is not primarily for travelers but for certain age groups and individuals with medical conditions at risk. Option D is incorrect as the vaccine's duration of protection can vary, and it is not guaranteed to prevent pneumococcal pneumonia for up to 5 years.
2. What are the requirements and qualifications for a regional nurse supervisor?
- A. BSN, RN
- B. at least 5 years of experience in public health
- C. Master's in public health
- D. all of the above
Correct answer: D
Rationale: To become a regional nurse supervisor, one must possess a BSN and RN credentials to ensure clinical competency. Additionally, a minimum of 5 years of experience in public health is required to demonstrate a solid understanding of the field. Lastly, holding a Master's degree in public health is essential for leadership and decision-making roles. Therefore, all the choices (BSN, RN; at least 5 years of experience in public health; Master's in public health) are necessary qualifications for a regional nurse supervisor.
3. During a health screening, a client's blood pressure reads 160/100 mm Hg. What should the nurse recommend?
- A. Schedule a follow-up appointment
- B. Start making immediate dietary changes
- C. Begin an exercise program
- D. All of the above
Correct answer: A
Rationale: A follow-up with a healthcare provider is necessary to assess and manage the newly identified hypertension. While dietary changes and exercise are important for managing high blood pressure, immediate lifestyle modifications without further evaluation by a healthcare provider may not be safe or effective. Option A is the most appropriate initial step to ensure proper assessment and management of the client's blood pressure. Therefore, choices B and C are incorrect in this scenario. Option D is also incorrect because not all options should be implemented without proper medical guidance.
4. Which of the following best describes the role of insulin in the body?
- A. Insulin helps break down glucose into energy for the body
- B. Insulin facilitates the movement of glucose into cells
- C. Insulin converts excess glucose into fat for storage
- D. Insulin increases the breakdown of protein into amino acids
Correct answer: B
Rationale: The correct answer is B: Insulin facilitates the movement of glucose into cells. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, where it can be used for energy production. Choice A is incorrect because insulin doesn't break down glucose but rather helps cells take up glucose. Choice C is incorrect as insulin does not directly convert glucose into fat; excess glucose is stored as fat by other processes. Choice D is incorrect as insulin does not increase the breakdown of protein into amino acids; its primary role is in glucose metabolism.
5. A healthcare professional is assessing a client’s extraocular eye movements. Which of the following should the professional do?
- A. Instruct the client to follow a finger through the six cardinal positions of gaze.
- B. Hold a finger 46 cm (18 in) away from the client’s eyes.
- C. Ask the client to cover their right eye during assessment of the left eye.
- D. Position the client 6.1 m (20 feet) away from the Snellen chart.
Correct answer: A
Rationale: Instructing the client to follow a finger through the six cardinal positions of gaze is the correct action when assessing extraocular eye movements. This technique assesses the movement of the eyes in all directions and helps to test cranial nerves 3, 4, and 6, which control eye movements. Choice B is incorrect as the distance mentioned is not relevant for assessing extraocular eye movements. Choice C is incorrect as both eyes need to be assessed independently. Choice D is incorrect as positioning the client 6.1 m (20 feet) away from the Snellen chart is related to visual acuity testing, not extraocular eye movements.
