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 of the following symptoms is not indicative of autonomic dysreflexia in the client with a spinal cord injury?

• A. sudden onset of headache
• B. flushed face
• C. hypotension
• D. nasal congestion

Correct answer: C

Rationale: Autonomic dysreflexia is characterized by a sudden onset of symptoms due to an overactive autonomic nervous system. Hypotension is not indicative of autonomic dysreflexia; instead, hypertension is a hallmark sign. Therefore, hypotension is the correct answer. Flushed face, sudden onset of headache, and nasal congestion are classic symptoms of autonomic dysreflexia caused by a noxious stimulus below the level of the spinal cord injury. These symptoms result from the body's attempt to regulate blood pressure when the normal feedback loop is interrupted.

3. A nurse is preparing for the admission of a client with pulmonary tuberculosis. Which action reflects the use of evidence-based practice in the care of the client?

• A. Keeping the door to the client's room closed
• B. Fitting the client for an N95 or HEPA (high-efficiency particulate air) mask to be worn at all times
• C. Placing the client in a semiprivate room with a cohort client
• D. Using a surgical mask when entering the client's room

Correct answer: A

Rationale: Evidence-based practice is an approach to client care that integrates the client's preferences, clinical expertise, and the best research evidence to deliver quality care. In the case of pulmonary tuberculosis, which is transmitted through the airborne route, keeping the door to the client's room closed is crucial to prevent the spread of infection. Placing the client in a semiprivate room with a cohort client is not recommended for airborne precautions; a private room is required to prevent transmission. Fitting the client for an N95 or HEPA mask is essential for the nurse's protection when entering the room, not for the client to wear at all times. Using a surgical mask when entering the client's room is not sufficient for airborne precautions; an N95 or HEPA mask is necessary.

4. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture.
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.

5. In an emergency situation where a client is unconscious and requires immediate surgery, what action is necessary with regard to informed consent?

• A. The healthcare team will proceed with the surgery as consent is not needed in emergencies.
• B. The healthcare team will wait until the client's family can be contacted for consent.
• C. The healthcare team will contact the hospital clergy to provide informed consent.
• D. The healthcare team will obtain consent from the client's legal guardian before proceeding.

Correct answer: A

Rationale: In emergency situations where obtaining consent is not possible due to the client's condition, healthcare providers are allowed to perform life-saving procedures without informed consent. It is assumed that the client would want to receive necessary treatment to save their life. Therefore, the correct action is for the healthcare team to proceed with the surgery as consent is not needed. Waiting to contact the client's family for consent can delay life-saving treatment, risking the client's life. Contacting the hospital clergy for consent is unnecessary and can cause further delays. Obtaining consent from the client's legal guardian is not feasible in this critical situation and may lead to a delay in providing essential care.
