1. Which of the following microorganisms are considered normal body flora?

A. staphylococcus on the skin
B. streptococcus in the nares
C. candida albicans in the vagina
D. pseudomonas in the blood

Correct answer: A

Rationale: Staphylococcus is considered normal body flora as it is commonly found on the skin, being a part of the normal microbiota. While streptococcus in the nares can be part of the normal flora of the upper respiratory tract, it is not as common or as widespread as staphylococcus on the skin. Candida albicans in the vagina is not considered normal flora; it is a common opportunistic pathogen in the vagina. Pseudomonas in the blood is also not considered normal body flora; pseudomonas is not typically found in the blood as part of the normal microbiota.

2. 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.

3. All of the following tasks could be delegated to a nursing assistant or unlicensed assistive personnel (UAP) except:

A. monitoring intravenous infusion
B. assisting a client to the bathroom
C. offering fluid intake every 1-2 hours
D. monitoring/recording the amount of fluid taken

Correct answer: A

Rationale: Monitoring an intravenous infusion involves assessing for complications, adjusting the flow rate, and monitoring the client's response, which requires the knowledge and skills of a licensed nurse (RN or LPN). Tasks that can be delegated to nursing assistants or unlicensed assistive personnel include assisting a client to the bathroom, offering fluids, and recording fluid intake. These activities are within the scope of practice for UAPs as they do not involve the specialized knowledge and training needed for intravenous infusion monitoring.

4. Ethics committees typically do not handle which of the following issues?

A. Nonpayment of bills.
B. Euthanasia.
C. Starting or stopping treatment.
D. Use of feeding tubes.

Correct answer: A

Rationale: Ethics committees primarily focus on addressing ethical dilemmas in healthcare. Issues like euthanasia, decisions regarding starting or stopping treatment, and the use of feeding tubes for nutritional support involve complex ethical considerations related to patient care and end-of-life decisions, which are commonly deliberated by ethics committees. However, nonpayment of bills is a financial matter and falls outside the typical scope of ethics committees' functions.

5. A nurse is planning client assignments for the day. Which task should the nurse assign to the nursing assistant (unlicensed assistive personnel)?

A. Recording the urinary output for a client with renal calculi whose urine must be strained
B. Dressing change instructions for a client who had a mastectomy 2 days ago
C. Reporting abnormal lab values to the health care provider for a client scheduled for a laparoscopic cholecystectomy
D. Preprocedural teaching for a client scheduled for a cardiac stress test

Correct answer: A

Rationale: The nurse is legally responsible for client assignments and must assign tasks based on state nursing practice act guidelines and job descriptions provided by the employing agency. The nursing assistant is trained to measure, collect, and strain urine, making recording urinary output for a client with renal calculi a suitable task for the nursing assistant. This task falls within the nursing assistant's role description. Dressing change instructions for a client who had a mastectomy involve a higher level of skill and knowledge, beyond the scope of a nursing assistant. Reporting abnormal lab values to the health care provider for a client scheduled for a laparoscopic cholecystectomy requires interpretation and clinical judgment, which is typically not within the nursing assistant's role. Preprocedural teaching for a client scheduled for a cardiac stress test involves providing detailed information and education, which is usually the responsibility of a licensed nurse or other qualified healthcare provider.
