Community Health HESI Study Guide
1. True or False: Vertical transmission is the disease-causing agent (pathogen) from mother to baby during the period immediately before and after birth.
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: A
Rationale: Vertical transmission is the transfer of a disease-causing agent (pathogen) from mother to baby during the period immediately before and after birth. This process can lead to the baby acquiring infections or diseases from the mother. Choice A is correct because it accurately describes vertical transmission. Choices B, C, and D are incorrect as they do not reflect the definition of vertical transmission.
2. Which other congenital defects are common in children with Down syndrome?
- A. Hypospadias
- B. Pyloric stenosis
- C. Heart defects
- D. Hip dysplasia
Correct answer: C
Rationale: The correct answer is C: Heart defects. Many children with Down syndrome are born with congenital heart defects. These heart abnormalities are more prevalent in individuals with Down syndrome than in the general population. Choices A, B, and D are incorrect because while they may be congenital defects in children, they are not commonly associated with Down syndrome. Hypospadias is a urogenital condition, pyloric stenosis affects the stomach, and hip dysplasia involves the hip joint, but these are not typically seen as frequently as heart defects in children with Down syndrome.
3. A nurse is providing teaching to a newly licensed nurse about the care of a client who has MRSA. Which of the following statements by the newly licensed nurse indicates an understanding of teaching?
- A. I will place the client in a private room
- B. I will tell the client’s visitors to wear a mask when they are within 3 feet of the client
- C. I will remove my gown after leaving the client’s room
- D. I will wear an N95 respirator mask when caring for the client
Correct answer: A
Rationale: The correct answer is A: 'I will place the client in a private room.' Placing the client in a private room helps prevent the spread of MRSA, a contact precaution. Choice B is incorrect because visitors should be following standard precautions for MRSA, not just wearing a mask within a specific distance. Choice C is incorrect as the gown should be removed before exiting the client's room to prevent the spread of MRSA. Choice D is incorrect as an N95 respirator mask is not typically required for the care of a client with MRSA; standard precautions are usually sufficient.
4. A female victim of sexual assault is being seen in the crisis center. The client states that she still feels 'as though the rape just happened yesterday,' even though it has been a few months since the incident. The appropriate nursing response is which of the following?
- A. You need to try to be realistic. The rape did not just occur.
- B. It will take some time to get over these feelings about your rape.
- C. Tell me more about the incident that causes you to feel like the rape just occurred.
- D. What do you think you can do to alleviate some of your fears about being raped again?
Correct answer: C
Rationale: The correct response is to encourage the client to talk about the event that makes them feel as though the rape just occurred. This approach can help the client process their feelings and experiences, which is crucial in dealing with trauma. Choice A is dismissive and negates the client's feelings, which can be harmful. Choice B, although acknowledging the time needed to heal, does not actively address the client's current feelings. Choice D shifts the focus to future fears rather than addressing the client's current emotional state.
5. What is the term for the study of how diet affects gene expression?
- A. Epigenetics
- B. Nutrigenomics
- C. Genomics
- D. Genetics
Correct answer: B
Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.
