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 is an indication for electroencephalography?

A. paralysis
B. neuropathy
C. seizure disorder
D. myocardial infarction

Correct answer: C

Rationale: The correct answer is C: 'seizure disorder.' Electroencephalography is used to assess clients with seizure disorders by recording the brain's electrical activity. Seizure disorder is a primary indication for an EEG as it helps in diagnosing and managing seizure activity. Paralysis (choice A) is not typically an indication for an EEG as it relates to loss of muscle function rather than brain activity. Neuropathy (choice B) involves nerve damage and is not directly assessed by an EEG. Myocardial infarction (choice D) is related to heart issues and is not a condition that an EEG is used to diagnose.

3. Delegation of tasks to appropriate personnel allows the nurse to:

A. ensure tasks are appropriately distributed.
B. keep other members of the team productive.
C. maintain tight control of all aspects of the workflow.
D. recognize the importance of team members' roles.

Correct answer: B

Rationale: Delegating tasks to appropriate personnel is essential for a nurse to keep other team members productive. By assigning tasks that align with the specific roles and responsibilities of team members, the nurse can enhance work effectiveness and efficiency. Option A is incorrect because delegation is not primarily about ensuring tasks are evenly distributed but rather about utilizing team members' skills effectively. Option C is incorrect as maintaining tight control of all aspects of the workflow can hinder teamwork and limit individual growth. Option D is incorrect because effective delegation involves empowering team members to make decisions within their scope of practice, rather than solely recognizing the importance of their roles.

4. What is the purpose of the hydraulic lift (Hoyer lift)?

A. To assist clients who have had orthopedic surgery.
B. To assist clients who are unable to stand and extremely obese clients.
C. To assist clients of all ages in a hospital setting.
D. To assist clients with special needs.

Correct answer: B

Rationale: The purpose of the hydraulic lift, also known as the Hoyer lift, is to facilitate safe transfers for clients who cannot stand or are extremely obese. It is specifically designed for assisting clients who are unable to stand and for those who are too heavy for healthcare workers to lift safely. Choice A is incorrect because the primary purpose of a hydraulic lift is not related to orthopedic surgery. Choice C is incorrect because it is too broad and does not capture the specific use of the hydraulic lift. Choice D is incorrect because the lift is not solely for clients with special needs but rather for those who cannot stand or are extremely obese.

5. Upon admission, the client expresses a desire for an extra oxygen tank in their room due to a previous breathing issue. What is the most appropriate response?

A. "I will make sure there is always an extra oxygen tank in your room."?
B. "I will ask the previous nurse if the extra tank was needed."?
C. "I will need to check if your insurance benefits would cover an additional oxygen tank."?
D. "The first priority is ensuring there are enough oxygen tanks for everyone who needs them. I am not sure we will be able to provide an extra on standby."?

Correct answer: D

Rationale: The appropriate response in this situation is to prioritize the availability of oxygen tanks for all patients in need. While it is understandable that the client may desire an extra tank for reassurance, the healthcare facility must ensure equitable distribution based on clinical need. Option A is incorrect because promising an always available extra tank may not be feasible and can set unrealistic expectations. Option B is not the best response as it focuses on past actions rather than addressing the current situation. Option C is not the most appropriate response at this time as the client's immediate need for an extra oxygen tank is the primary concern. Therefore, the best response is to emphasize the importance of equitable distribution of resources while acknowledging the client's request for an extra tank.
