Community Health HESI Study Guide
1. From January 1 to 15, 1996, there were 8 cases of Tetanus neonatorum in San Lazaro Hospital. There were two deaths. What is the case fatality ratio of this disease?
- A. 20%
- B. 30%
- C. 28%
- D. 25%
Correct answer: D
Rationale: The case fatality ratio is calculated as (deaths/cases) * 100. In this case, there were 2 deaths out of 8 cases. Therefore, the calculation is (2/8) * 100 = 25%. Choices A, B, and C are incorrect as they do not match the correct calculation.
2. The Philippine Family Program seeks to improve and maintain which of the following life-saving measures?
- A. proper spacing of pregnancies
- B. proper timing of pregnancies
- C. fewer pregnancies
- D. all of the above
Correct answer: D
Rationale: The correct answer is D, all of the above. The Philippine Family Program aims to enhance and sustain proper spacing of pregnancies, proper timing of pregnancies, and reducing the number of pregnancies. These measures are essential for promoting maternal and child health, preventing complications, and ensuring better outcomes. Choices A, B, and C are all part of the comprehensive approach taken by the program to safeguard the well-being of families and contribute to overall public health.
3. A client with a body mass index (BMI) of 30 is seeking advice on the initial approach to a weight loss plan. What action should the nurse recommend?
- A. Plan meals with low carbohydrates and high protein
- B. Engage in strenuous activity for an hour daily
- C. Keep a record of daily food and beverage intake
- D. Participate in a group exercise class three times a week
Correct answer: C
Rationale: Keeping a food diary is an essential practice when starting a weight loss plan as it helps in tracking calorie intake, identifying eating patterns, and making informed decisions about dietary changes. Planning meals with low carbohydrates and high protein (Choice A) can be beneficial for some individuals, but keeping a food diary is more foundational. Engaging in strenuous daily activity (Choice B) may not be sustainable for everyone and could lead to burnout or injuries. Participating in a group exercise class (Choice D) is beneficial for fitness but may not address dietary habits, which are crucial for weight loss.
4. During a peripheral vascular assessment, a healthcare professional places the bell of the stethoscope on a client's neck and hears an audible vascular sound associated with turbulent blood flow. This sound indicates which of the following?
- A. Narrowed arterial lumen
- B. Distended jugular veins
- C. Impaired ventricular contraction
- D. Asynchronous closure of the aortic and pulmonic valve
Correct answer: A
Rationale: The correct answer is A: Narrowed arterial lumen. Arterial bruits are abnormal sounds caused by turbulent blood flow through narrowed or occluded arteries. This turbulent flow creates a blowing sound, which is heard as an arterial bruit. Distended jugular veins (choice B) are typically associated with venous issues, not arterial abnormalities. Impaired ventricular contraction (choice C) and asynchronous closure of the aortic and pulmonic valve (choice D) are not directly related to the audible vascular sound described in the scenario.
5. A client who is receiving general anesthesia begins to demonstrate symptoms of malignant hyperthermia. Which intervention should the perioperative nurse prepare to implement first?
- A. Ensure patency of an indwelling catheter and measure hourly intake and output.
- B. Prepare for cessation of the anesthesia and the surgical procedure.
- C. Obtain specimens of ABGs and serum electrolytes.
- D. Initiate cooling measures using iced normal saline by nasogastric lavage.
Correct answer: B
Rationale: The correct answer is B: Prepare for cessation of the anesthesia and the surgical procedure. Malignant hyperthermia is a severe reaction to certain medications used during general anesthesia. The immediate intervention to manage malignant hyperthermia is to stop the triggering agents, which include anesthesia and surgery. Ensuring patency of an indwelling catheter and measuring intake and output, obtaining specimens of ABGs and serum electrolytes, and initiating cooling measures are important interventions but should follow the immediate action of stopping the anesthesia and surgery to address the life-threatening condition of malignant hyperthermia.
