1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

2. A client has signed the informed consent for mastectomy of the left breast. On the morning of the surgical procedure, the client asks the nurse several questions about the procedure that make it obvious that she does not have an adequate comprehension of the procedure. What is the most appropriate response by the nurse?

• A. Telling the client that she needed to ask these questions before signing the informed consent for surgery
• B. Contacting the surgeon and requesting that she visit the client to answer her questions
• C. Informing the client that she has the right to cancel the surgical procedure if she wishes
• D. Telling the client that it is her surgeon's responsibility to explain the procedure

Correct answer: B

Rationale: Informed consent is the authorization by a client or a client's legal representative to do something to the client. The surgeon is primarily responsible for explaining the surgical procedure and obtaining informed consent. If the client asks questions that alert the nurse to an inadequacy of comprehension on the client's part, the nurse has the obligation to contact the surgeon. Choice A is incorrect as the client should be allowed to ask questions even after signing the consent for surgery. Choice C is not the most appropriate response, as the primary concern is to address the client's lack of comprehension. Choice D is inaccurate, as while it is the surgeon's responsibility to explain the procedure, in this scenario, the nurse should take immediate action to ensure the client's understanding. Requesting the surgeon to visit and answer the client's questions is the most appropriate response in this situation, as it directly addresses the client's concerns and ensures proper informed consent is obtained.

3. 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.

4. When a physician removes a chest tube, which type of dressing is recommended to be placed over the site?

• A. transparent dressing
• B. colloidal dressing
• C. petrolatum gauze
• D. nonadherent dressing

Correct answer: C

Rationale: Petrolatum gauze is recommended to be placed over the site when a physician removes a chest tube because it forms an airtight seal, helping prevent air from entering the pleural space. This airtight seal is crucial to avoid complications such as a pneumothorax. Transparent dressing is not ideal for this purpose as it may not provide a sufficient seal due to its design. Colloidal dressing and nonadherent dressing are also not suitable for chest tube removal sites as they do not offer the same level of protection against air leakage and may not provide the necessary sealing properties.

5. A client admitted to the hospital has a do-not-resuscitate (DNR) order in his medical record. The nurse understands which information about DNR orders?

• A. The only individuals who may change the DNR order are healthcare providers
• B. The DNR order can be changed if the client's condition warrants it
• C. The DNR order does not remain fixed for the duration of the client's hospitalization
• D. The DNR order requires frequent review as specified by state or agency policy

Correct answer: D

Rationale: The correct answer is that the DNR order requires frequent review as specified by state or agency policy. If the client's condition changes, the DNR order may need to be changed. For this reason, DNR orders require frequent review as specified by state or agency policy. A DNR order may be changed at any time and does not remain in effect for the duration of the client's hospitalization. The client's request regarding DNR status is the priority. Choice A is incorrect because healthcare providers, not just immediate family members, may change the DNR order based on the client's condition. Choice B is incorrect as DNR orders can be changed if the client's condition warrants it, not remaining unchanged. Choice C is incorrect as DNR orders are not fixed for the duration of hospitalization, they can be modified based on the client's needs.
