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 community health nurse has been following the care for an adolescent with a history of morbid obesity, asthma, hypertension, and is 22 weeks into a pregnancy. Which of these lab reports sent to the clinic needs to be called to the teen's healthcare provider within the next hour?
- A. Hemoglobin 11 g/dL and calcium 6 mg/dL
- B. Magnesium 0.8 mEq/L and creatinine 3 mg/dL
- C. Blood urea nitrogen 28 mg/dL and glucose 225 mg/dL
- D. Hematocrit 33% and platelets 200,000
Correct answer: B
Rationale: The correct answer is B. The low magnesium level and elevated creatinine suggest possible renal dysfunction, which is concerning, especially in a pregnant client with multiple risk factors such as morbid obesity, asthma, and hypertension. Immediate attention is needed to address the potential renal issues. The other choices do not indicate such urgent conditions. Hemoglobin and calcium levels in choice A are within acceptable ranges. Choice C shows elevated blood urea nitrogen and glucose levels, which may need monitoring but not immediate attention. Choice D's hematocrit and platelet levels are also within normal ranges and do not indicate an urgent issue.
3. A nurse manager is using the technique of brainstorming to help solve a problem. One nurse criticizes another nurse’s contribution and begins to find objections to the suggestion. The nurse manager's best response is to
- A. Let’s move on to a new action that deals with the problem.
- B. I think you need to reserve judgment until after all suggestions are offered.
- C. Very well thought out. Your analytic skills and interest are incredible.
- D. Let’s move to the ‘what if…’ as related to these objections for an exploration of spin-off ideas.
Correct answer: D
Rationale: Encouraging the group to explore 'what if' scenarios based on the objections helps to maintain a positive and creative brainstorming atmosphere, while also validating the concerns raised by the nurse. Choice A is dismissive and does not address the issue at hand. Choice B suggests postponing judgment, which may not resolve the tension caused by the criticism. Choice C is complimentary but does not address the critical feedback provided by the nurse, missing an opportunity to turn objections into opportunities for further exploration.
4. For whom is the community health nurse primarily responsible?
- A. individuals
- B. populations
- C. families
- D. class E citizens
Correct answer: B
Rationale: Community health nurses are primarily responsible for populations. While they do provide care and support to individuals and families within the community, their focus is on the health and well-being of entire populations. Choice A is incorrect as the primary responsibility is broader than just individuals. Choice C is incorrect as families are part of the population but not the sole focus. Choice D, 'class E citizens', is too specific and not a standard term in public health, making it an incorrect choice.
5. In the provision of preventive care to workers, the nurse must be aware of biological hazards that are harmful to workers and their families, such as:
- A. bacteria, fungi, and insects
- B. noise
- C. toxic metals, poisonous gas fumes, and dust
- D. stress
Correct answer: A
Rationale: The correct answer is A: bacteria, fungi, and insects. Biological hazards in the workplace can include microorganisms like bacteria and fungi that can cause infections, as well as insects that may carry diseases. Noise (choice B) is considered a physical hazard, not a biological one. Toxic metals, poisonous gas fumes, and dust (choice C) are examples of chemical hazards, not biological hazards. While stress (choice D) can be a health concern in the workplace, it is not classified as a biological hazard.
