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 nurse is performing suctioning through an adult client's tracheostomy tube. The nurse notes that the client's oxygen saturation is 89% and terminates the procedure. Which action would the nurse take next?

• A. Rechecking the pulse oximetry reading
• B. Calling the respiratory therapist
• C. Calling the healthcare provider
• D. Oxygenating the client with 100% oxygen

Correct answer: D

Rationale: The nurse should monitor the client's heart rate and pulse oximetry during suctioning to assess the client's tolerance of the procedure. Oxygen desaturation to below 90% indicates hypoxemia. If hypoxia occurs during suctioning, the nurse must terminate the procedure and oxygenate the client with 100% oxygen to address the hypoxemia promptly and ensure the client's safety. Rechecking the pulse oximetry reading is important, but the priority is to address the hypoxemia by providing oxygen. Contacting the healthcare provider or respiratory therapist is not necessary at this time as the nurse can manage the hypoxemia with oxygenation. Oxygenating the client with 100% oxygen is the immediate action required in this situation.

3. Which of the following is true of advanced directives?

• A. They should be appropriately documented in the client's chart.
• B. They are only applicable if the client has a terminal illness.
• C. They are required if the client is unconscious.
• D. They are non-legal requests.

Correct answer: A

Rationale: The correct answer is that advanced directives should be appropriately documented in the client's chart. Advanced directives are legal requests regarding a client's healthcare that come into effect under specific circumstances, regardless of the severity of their illness or level of consciousness. Choice B is incorrect because advanced directives can cover various healthcare decisions, not just terminal illnesses. Choice C is incorrect as advanced directives can be established and documented while the client is conscious, not only if they are unconscious. Choice D is incorrect because advanced directives are indeed legal requests, not non-legal requests.

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. Which of the following tests is commonly performed on newborns with jaundice?

• A. blood urea nitrogen
• B. magnesium
• C. bilirubin
• D. prolactin

Correct answer: C

Rationale: The correct answer is C: bilirubin. A high bilirubin level is found in newborns with hepatic immaturity, leading to jaundice. Testing bilirubin levels is crucial in diagnosing and monitoring jaundice in newborns. Choices A, B, and D (blood urea nitrogen, magnesium, and prolactin) are not commonly performed tests for evaluating jaundice in newborns. Blood urea nitrogen is a measure of kidney function, magnesium levels are usually checked in metabolic disorders, and prolactin is a hormone related to lactation, none of which are directly relevant to assessing jaundice in newborns.
