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. The nurse is preparing to administer the 9 am dose of IV antibiotics when she notes the IVAC cord is frayed with wiring visible. What action should be her priority for this client?

A. Notify maintenance to come and check the pump immediately.
B. Continue with the administration of the antibiotic and fill out an equipment maintenance request.
C. Immediately discontinue the use of this IVAC pump and obtain a replacement.
D. Tag the equipment for maintenance.

Correct answer: C

Rationale: The correct action is to immediately discontinue the use of the IVAC pump and obtain a replacement because the frayed cord poses a safety risk to the client. Continuing to use the pump with visible wiring could lead to electric shock or other serious harm to the client. Notifying maintenance to come and check the pump immediately (Choice A) may cause unnecessary delays in ensuring the client's safety. Continuing with the administration of the antibiotic and filling out an equipment maintenance request (Choice B) is unsafe as it ignores the immediate danger. Tagging the equipment for maintenance (Choice D) does not address the urgent need to protect the client from harm.

3. A nurse enters a client's room to administer a medication that has been prescribed by the health care provider. The client asks the nurse about the medication. Which response by the nurse is appropriate?

A. 'I know that it's for fluid buildup, and I think you've taken it before.''
B. 'It's called furosemide (Lasix), and it will promote urination and rid your body of the excess fluid. It can cause an alteration in electrolyte levels, so we'll need to increase the potassium in your diet.''
C. 'It's to help get rid of the swelling in your feet.''
D. ''You need to discuss this medication with your health care provider.''

Correct answer: B

Rationale: A client has the right to be informed of the medication name, purpose, action, and potential undesirable effects of a prescribed medication. The nurse should provide adequate information to the client. Choice B is the correct answer as it includes the medication name, its purpose (promoting urination and eliminating excess fluid), and a potential side effect (alteration in electrolyte levels) with a plan for managing it (increasing potassium in the diet). This response demonstrates thorough and complete information. Choice A provides some information but lacks details on potential side effects and dietary adjustments. Choice C is vague and does not provide specific details about the medication. Choice D deflects the client's question and does not fulfill the client's right to information.

4. Which of the following statements is true about syphilis?

A. The cause and mode of transmission are well understood.
B. There is no known cure for the disease.
C. When the primary lesion heals, the disease is cured.
D. Syphilis can be cured with a course of antibiotic therapy.

Correct answer: D

Rationale: The correct statement about syphilis is that it can be cured with a course of antibiotic therapy. Syphilis is a treponemal disease that can be effectively treated with antibiotics, particularly long-acting penicillin G. The primary lesion of syphilis, known as a chancre, typically appears about three weeks after exposure and can involute even without specific treatment. If left untreated, secondary manifestations may occur, followed by latent periods. Specific treatment with antibiotics is crucial to prevent progression and transmission of the disease. Therefore, option D is correct. Option A is incorrect because the cause and mode of transmission of syphilis are well understood. Option B is incorrect as there is a known cure for syphilis. Option C is incorrect because the healing of the primary lesion does not indicate a cure for the disease.

5. People living in poverty are most likely to obtain health care from:

A. their primary care physician (family doctor)
B. a neighborhood clinic
C. specialists
D. Emergency Departments or urgent care centers

Correct answer: D

Rationale: People living in poverty often face barriers to accessing regular healthcare services, leading them to seek care in Emergency Departments or urgent care centers. These facilities are more accessible and do not require appointments or insurance, making them a common choice for individuals with limited resources. Neighborhood clinics, while a good option, may not always be available or affordable for those in poverty. Specialists provide specialized care but usually require a referral from a primary care provider, which individuals in poverty may not have consistent access to. Therefore, Emergency Departments or urgent care centers are the most likely sources of healthcare for people living in poverty.
