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. A health care provider informs a nurse that the husband of an unconscious client with terminal cancer will not grant permission for a do-not-resuscitate (DNR) order. The health care provider tells the nurse to perform a 'slow code' and let the client 'rest in peace' if she stops breathing. How should the nurse respond?

A. Telling the health care provider that the client would probably want to die in peace
B. Telling the health care provider that if the client stops breathing, the health care provider will be called before any other actions are taken
C. Telling the health care provider that all of the nurses on the unit agree with this plan
D. Telling the health care provider that 'slow codes' are not acceptable

Correct answer: D

Rationale: The nurse may not violate a family's request regarding the client's treatment plan. A 'slow code' is not acceptable, and the nurse should state this to the health care provider. The definition of a 'slow code' varies among health care facilities and personnel and could be interpreted as not performing resuscitative procedures as quickly as a competent person would. Resuscitative procedures that are performed more slowly than recommended by the American Heart Association are below the standard of care and could therefore serve as the basis for a lawsuit. The other options are inappropriate: Option A is speculative and does not address the issue directly; Option B does not challenge the unethical practice of a 'slow code'; Option C is irrelevant and does not address the ethical concerns raised by the health care provider's request.

3. Which type of diet should the nurse provide to help a client who has major burns maintain a positive nitrogen balance?

A. high protein
B. high carbohydrate
C. low carbohydrate
D. low protein

Correct answer: A

Rationale: Clients with major burns are in a hypermetabolic state, leading to increased protein catabolism. Therefore, a high-protein diet is essential to help them maintain a positive nitrogen balance and support wound healing. High carbohydrate diets do not directly contribute to achieving a positive nitrogen balance, making choice B incorrect. Similarly, low carbohydrate diets are not recommended for clients with major burns as carbohydrates provide essential energy needed for healing. Low protein diets are contraindicated for clients with major burns as they require higher protein intake to support tissue repair and prevent further breakdown.

4. Which situation is an example of the use of evidence-based practice in the delivery of client care?

A. Encouraging a client who has had a stroke to consume thickened liquids and soft foods
B. Picking up a dislodged radiation implant with long-handled forceps and placing it in a lead container to minimize radiation exposure
C. Pouring 1 to 2 mL of sterile solution that will be used for wound cleansing into a plastic-lined waste receptacle before pouring the solution into a sterile basin
D. Blowing on a fingerstick site to dry it after cleaning the site with an alcohol swab

Correct answer: C

Rationale: Evidence-based practice is an approach that integrates client preferences, clinical expertise, and the best research evidence to deliver quality care. Pouring sterile solution into a plastic-lined waste receptacle before using it for wound cleansing reflects evidence-based practice by preventing the entrance of harmful bacteria into the wound. Option A is incorrect because encouraging a stroke client to consume thickened liquids and soft foods is appropriate, not thin liquids and foods that pose a choking risk. Option B is incorrect as picking up a radiation implant with long-handled forceps to minimize radiation exposure is a safety measure, not evidence-based practice. Option D is incorrect because blowing on a fingerstick site after cleaning can recontaminate the site, which goes against best practices in infection control.

5. The LPN is caring for a client with an NG tube, and the RN administers evening medications through the NG tube. The client asks if he can lie down when the nurse leaves the room. What is the most appropriate response?

A. You can lie down in 1 hour.
B. You can lie down in 30 minutes if your NG residual is below 50 mL.
C. You can lie down in about 30 minutes.
D. Yes, feel free to lie down.

Correct answer: A

Rationale: After administering medication through an NG tube, the client should remain upright for 30 minutes to ensure proper absorption of the medications. Therefore, the most appropriate response is to advise the client to lie down in 1 hour. Choice B is incorrect because waiting only 30 minutes may not provide sufficient time for the medications to be fully absorbed, as the recommended time is 30 minutes. Choice C is misleading as it incorrectly suggests that lying down in about 30 minutes is acceptable, which could compromise medication effectiveness. Choice D is incorrect as it does not provide accurate information regarding the appropriate timing for lying down after NG tube medication administration, potentially leading to decreased medication absorption.
