Community Health HESI Questions
1. As a community Health Nurse, you are a change agent. Which of the following roles must you play to succeed as a change agent?
- A. information provider
- B. information seeker
- C. motivator
- D. leader
Correct answer: B
Rationale: To succeed as a change agent, being an information seeker is crucial. While being an information provider, motivator, and leader are important roles, actively seeking information is fundamental to understanding the community's needs, concerns, and challenges before implementing effective changes. This active information seeking helps in making informed decisions and developing strategies that address the specific issues faced by the community. Therefore, the correct choice is B. Choices A, C, and D are also important roles but may not be as fundamental as actively seeking information.
2. Which statement about adjuvant medications is true and accurate?
- A. Licensed practical nurses can administer adjuvant medications.
- B. Adjuvant medications are schedule 2 narcotics.
- C. Adjuvant medications are schedule 1 narcotics.
- D. Adjuvant medications can be purchased over the counter.
Correct answer: D
Rationale: The correct answer is D because adjuvant medications are often available over the counter without a prescription. Choices A, B, and C are incorrect. Choice A is incorrect because licensed practical nurses can administer adjuvant medications depending on their scope of practice. Choices B and C are incorrect because adjuvant medications are not classified as schedule 1 or schedule 2 narcotics.
3. Why is randomization important in a scientific experiment?
- A. To minimize the impact of confounding variables.
- B. To eliminate bias in the assignment of subjects to groups.
- C. To contribute to the accuracy and validity of the experiment's results.
- D. To prevent systematic differences between groups.
Correct answer: B
Rationale: Randomization is crucial in a scientific experiment to eliminate bias in the assignment of subjects to groups. By randomly assigning subjects, it helps ensure that any differences observed in the outcomes are due to the experimental treatment and not to preexisting differences between groups. Choice A is incorrect because randomization does not guarantee representativeness but rather minimizes the impact of confounding variables. Choice C is not entirely accurate; while randomization can contribute to accuracy and validity, its primary purpose is to reduce bias. Choice D is incorrect as the goal of randomization is not to balance the number of subjects but to prevent systematic differences between groups.
4. What is the central layer of the embryo from which the bones and muscles develop?
- A. neural tube
- B. mesoderm
- C. ectoderm
- D. umbilical cord
Correct answer: B
Rationale: The correct answer is mesoderm. The mesoderm is the middle layer of the embryo that gives rise to the bones, muscles, and other connective tissues. The neural tube (choice A) develops into the nervous system, not bones and muscles. The ectoderm (choice C) forms the skin and nervous system, not bones and muscles. The umbilical cord (choice D) is a structure that connects the developing fetus to the placenta; it is not a layer of the embryo that gives rise to bones and muscles.
5. The nurse is caring for an 8-year-old girl with an endocrine disorder involving the posterior pituitary gland. What care would the nurse expect to implement?
- A. Instructing the parents to report adverse reactions to the growth hormone treatment
- B. Teaching the parents how to administer desmopressin acetate
- C. Informing the parents that treatment stops when puberty begins
- D. Educating the parents to report signs of acute adrenal crisis
Correct answer: B
Rationale: In a child with a disorder of the posterior pituitary gland, desmopressin acetate is commonly used to manage the condition by replacing the antidiuretic hormone. Instructing the parents to administer desmopressin acetate correctly is essential for the child's treatment. The other options are incorrect because growth hormone treatment, stopping treatment at puberty, and reporting signs of acute adrenal crisis are not directly related to managing a disorder of the posterior pituitary gland.
