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. 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.

3. Several passengers aboard an airliner suddenly become weak and suffer breathing difficulty. The diagnosis is likely to be:

• A. Outbreak of Asian flu.
• B. Chemical exposure.
• C. Bacterial pneumonia.
• D. Allergic reaction.

Correct answer: B

Rationale: The most likely cause of groups of individuals suddenly experiencing similar signs of illness all at once is a chemical exposure. In this scenario, considering the sudden onset of symptoms in multiple passengers on an airliner, the symptoms are more indicative of a chemical exposure rather than Asian flu, bacterial pneumonia, or an allergic reaction. Asian flu, bacterial pneumonia, and allergic reactions do not typically manifest in a way that would affect a group of individuals simultaneously. Therefore, the correct diagnosis in this case is likely to be a chemical exposure.

4. What spinal change occurring with pregnancy alters mobility?

• A. Scoliosis.
• B. Kyphosis.
• C. Lordosis.
• D. Ankylosing spondylitis.

Correct answer: C

Rationale: The correct answer is 'Lordosis.' During pregnancy, the enlarging uterus places increased weight on the spine, causing an exaggerated inward curvature known as lordosis. This change alters mobility by shifting the center of gravity forward, leading to a compensatory change in posture. Scoliosis (choice A) is a sideways curvature of the spine, not typically associated with pregnancy. Kyphosis (choice B) is an exaggerated outward curvature of the spine, while ankylosing spondylitis (choice D) is a chronic inflammatory condition affecting the spine, neither of which are directly related to the spinal changes seen in pregnancy.

5. Regardless of their practice area, nurses should be concerned with:

• A. all drug-resistant bacteria.
• B. microorganisms that are critical.
• C. transmission of microorganisms.
• D. overprescription of bacteriostatic drugs.

Correct answer: C

Rationale: All nurses should be concerned with preventing the transmission of microorganisms to themselves and others. A primary way to achieve this is through asepsis. Nursing practice emphasizes providing a safe environment to shield clients, family, and healthcare providers from infections. Choices A, B, and D are incorrect. While drug-resistant bacteria, critical microorganisms, and overprescription of bacteriostatic drugs are important, nurses' primary focus should be on preventing microorganism transmission to ensure safety and well-being.
