1. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?
- A. blood urea nitrogen
- B. serum calcium
- C. serum ammonia
- D. serum creatinine
Correct answer: C
Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.
2. A nurse is preparing for the admission of a client with pulmonary tuberculosis. Which action reflects the use of evidence-based practice in the care of the client?
- A. Keeping the door to the client's room closed
- B. Fitting the client for an N95 or HEPA (high-efficiency particulate air) mask to be worn at all times
- C. Placing the client in a semiprivate room with a cohort client
- D. Using a surgical mask when entering the client's room
Correct answer: A
Rationale: Evidence-based practice is an approach to client care that integrates the client's preferences, clinical expertise, and the best research evidence to deliver quality care. In the case of pulmonary tuberculosis, which is transmitted through the airborne route, keeping the door to the client's room closed is crucial to prevent the spread of infection. Placing the client in a semiprivate room with a cohort client is not recommended for airborne precautions; a private room is required to prevent transmission. Fitting the client for an N95 or HEPA mask is essential for the nurse's protection when entering the room, not for the client to wear at all times. Using a surgical mask when entering the client's room is not sufficient for airborne precautions; an N95 or HEPA mask is necessary.
3. A nurse planning care for her assigned clients understands that which aspect is the purpose of the hospital's standards of care?
- A. Identify methods of treatment.
- B. Provide direction for care based on the client's diagnosis.
- C. Identify new care methods based on current medical research.
- D. Provide direction for the practice of nursing
Correct answer: D
Rationale: The purpose of the hospital's standards of care is to provide a broad direction for the overall practice of nursing that applies to all nursing situations, across specialty areas, and across the country. These standards guide the practice of nursing by outlining the expected level of care and professional performance. While identifying methods of treatment is important, it is usually specific to individual client needs and not the overarching goal of standards of care. Providing direction for care solely based on the client's diagnosis is limited to a particular patient's treatment plan and does not encompass the broader scope of nursing practice. Identifying new care methods based on current medical research is essential for advancing healthcare practices but is not the primary purpose of the hospital's standards of care.
4. When removing a client's gown with an intravenous line, what should the nurse do?
- A. temporarily disconnect the intravenous tubing at a point close to the client and thread it through the gown
- B. cut the gown with scissors
- C. thread the bag and tubing through the gown sleeve, keeping the line intact
- D. temporarily disconnect the tubing from the intravenous container and thread it through the gown
Correct answer: C
Rationale: The correct action when removing a client's gown with an intravenous line is to thread the bag and tubing through the gown sleeve while keeping the line intact. This method ensures that the system remains sterile and reduces the risk of infection. Temporarily disconnecting the tubing at a point close to the client or from the container introduces the potential for contamination. Cutting the gown with scissors should only be done in emergencies as it is not a standard practice and can compromise the integrity of the intravenous line. Therefore, the most appropriate and safe method is to thread the bag and tubing through the gown sleeve.
5. An example of a process standard on a med-surg unit is:
- A. a procedure for changing IV tubing.
- B. a policy for staffing.
- C. the job description of the CEO (chief executive officer).
- D. a procedure for checking waveforms on a client being treated with an intra-aortic balloon pump.
Correct answer: D
Rationale: Process standards define the actions and behaviors required by staff to provide care on a med-surg unit. A procedure for changing IV tubing is a critical psychomotor skill necessary for safe and effective patient care in this setting. Choice B, a policy for staffing, pertains more to organizational management rather than specific care processes on the unit. Choice C, the job description of the CEO, delineates the responsibilities of the organization's top executive and is not a process standard for frontline staff. Choice D, a procedure for checking waveforms on a client with an intra-aortic balloon pump, is more specific to a cardiac care unit and not typically performed on a med-surg unit.
