A test that can correctly identify those who do not have a given disease is:
- A. specific.
- B. sensitive.
- C. negative culture
- D. marginal finding.
Correct Answer: A
Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.

What is the role of an incident report in risk management?
- A. To provide liability protection.
- B. To provide data for analysis by a risk manager to determine how future problems can be avoided.
- C. To discipline staff for errors.
- D. All of the above.
Correct Answer: B
Rationale: The correct answer is B. Incident reports play a crucial role in risk management by providing data for analysis to prevent future problems. They are not primarily for liability protection (A) or disciplining staff (C). Therefore, choice B is the most appropriate answer. Choosing option D is incorrect because incident reports do not solely exist for all the mentioned purposes, but primarily to provide data for analysis and preventive actions.
When planning play activities for a hospitalized school-age child, a nurse uses Erikson's theory of psychosocial development to select an appropriate activity. The nurse selects an activity that will assist the child in developing which developmental goal?
- A. A sense of industry
- B. Autonomy
- C. A sense of trust
- D. Initiative
Correct Answer: C
Rationale: The correct answer is 'A sense of industry.' According to Erikson, the central task of the school-age years is the development of a sense of industry. During this stage, children engage in activities like schoolwork, crafts, chores, hobbies, and sports to develop a sense of competence and productivity. The development of trust is the primary task of infancy, autonomy is the task of toddlerhood, and initiative is the task of the preschool years. Therefore, in this scenario, focusing on fostering a sense of industry aligns with the developmental goals of a school-age child.
Which of the following lab values is elevated first after a client has a myocardial infarction?
- A. LDH
- B. troponin
- C. CPK
- D. SGOT
Correct Answer: B
Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.
The nurse is educating a teenage female about preventing the transmission of genital herpes. Which of the following statements should the nurse include?
- A. "Do not sit on toilet seats without protection."?
- B. "Oral sex can transmit the virus."?
- C. "This infection can be transmitted via intercourse even when you do not feel ill."?
- D. "Try to drink plenty of fluids after sex to flush the reproductive tract."?
Correct Answer: C
Rationale: Genital herpes can be transmitted through oral, genital, and anal sex. It is crucial to educate the patient that the infection can be transmitted via intercourse even when asymptomatic to prevent its spread. Choice A is incorrect as sitting on toilet seats without protection does not transmit genital herpes. Choice B is incorrect because oral sex can transmit the virus. Choice D is also incorrect as drinking fluids after sex does not prevent the transmission of genital herpes.
The method of splinting is always dictated by:
- A. location of the injury and whether it is open or closed.
- B. the severity of the client's condition and the priority decision.
- C. the number of available rescuers and the type of splints.
- D. all of the above.
Correct Answer: B
Rationale: The correct answer is 'the severity of the client's condition and the priority decision.' When determining the method of splinting, it is crucial to consider the severity of the client's condition and make decisions based on their priority. Choice A is incorrect because while the location of the injury and whether it is open or closed are important factors, they do not always dictate the method of splinting. Choice C is incorrect as the number of available rescuers and the type of splints may impact the execution of splinting but do not solely dictate the method. Choice D is incorrect as it suggests that all the factors mentioned dictate the method, but in reality, the severity of the client's condition and the priority decision are the primary factors.
