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 new graduate nurse interviews for a position in a nursing department of a large health care agency, described by the interviewer as having shared governance. Which of these statements best illustrates the shared governance model?
- A. An appointed board oversees any administrative decisions
- B. Nursing departments share responsibility for client outcomes
- C. Staff groups are appointed to discuss nursing practice and client education issues
- D. Non-nurse managers supervise nursing staff in groups of units
Correct answer: B
Rationale: The correct answer is B because shared governance involves nurses and other staff sharing responsibility for decisions related to patient care and outcomes, promoting collaborative practice and shared accountability. Choice A is incorrect as shared governance includes active participation of frontline staff, not just an appointed board. Choice C is incorrect because shared governance goes beyond just discussing issues to actively sharing responsibility for decision-making. Choice D is incorrect as shared governance encourages nurses to have a significant role in decision-making rather than being supervised by non-nurse managers.
3. Which of the following is used to monitor specific groups eligible for a particular DOH program?
- A. Family treatment record
- B. Target Client list
- C. Reporting forms
- D. Output record
Correct answer: B
Rationale: The correct answer is B: Target Client list. The Target Client list is specifically designed to monitor groups that are eligible for a particular DOH program. It helps in identifying and tracking individuals or populations that qualify for the said program. Choice A, Family treatment record, is incorrect because it pertains to the medical history and treatment information of a particular family, not eligibility monitoring. Choice C, Reporting forms, is incorrect as they are used for documenting and submitting information, not for monitoring eligibility. Choice D, Output record, is also incorrect as it refers to the results or outcomes produced by a system, not for monitoring eligibility.
4. The nurse is teaching a client about the healthy use of ego defense mechanisms. An appropriate goal for this client would be
- A. Reduce fear and protect self-esteem
- B. Minimize anxiety and delay apprehension
- C. Avoid conflict and leave unpleasant situations
- D. Increase independence and communicate more effectively
Correct answer: A
Rationale: The correct answer is A: 'Reduce fear and protect self-esteem.' When teaching a client about the healthy use of ego defense mechanisms, the goal is to help the individual manage emotions effectively without denying reality. Using defense mechanisms in a healthy way aims to reduce fear and protect self-esteem while still addressing underlying issues. Choices B, C, and D are incorrect because they do not focus on the core principles of using defense mechanisms in a healthy manner. Minimizing anxiety and delaying apprehension, avoiding conflict and leaving unpleasant situations, and increasing independence and communicating more effectively do not directly align with the goal of utilizing ego defense mechanisms in a constructive way.
5. The nurse at a health fair has taken a client's blood pressure twice, 10 minutes apart, in the same arm while the client is seated. The nurse records the two blood pressures of 172/104 mm Hg and 164/98 mm Hg. What is the appropriate nursing action in response to these readings?
- A. Refer the client to a nutritionist after providing health teaching about a low-sodium diet.
- B. Place the client in a recumbent position and call the paramedics for transport to the hospital.
- C. Talk with the client to assess whether there is stress in the client's life and refer to a counseling service.
- D. Take the client's blood pressure in the other arm and then schedule a healthcare practitioner's appointment for as soon as possible.
Correct answer: D
Rationale: The appropriate nursing action in response to significantly high blood pressure readings like 172/104 mm Hg and 164/98 mm Hg is to confirm the readings by taking the blood pressure in the other arm. This can help rule out any error or issue specific to that arm. The nurse should then schedule a healthcare practitioner's appointment for as soon as possible to further assess the client's condition and determine the appropriate intervention. Choice A is incorrect because solely referring the client to a nutritionist for a low-sodium diet without further assessment or confirmation of the blood pressure readings is premature. Choice B is incorrect as the client is already seated, and calling paramedics for immediate transport to the hospital is not warranted based solely on the blood pressure readings provided. Choice C is incorrect as stress may not be the sole reason for the high blood pressure readings, and further assessment is required before referring the client to counseling services.
