Nursing Elites

1. Which of the following is a characteristic of disseminated intravascular coagulation (DIC)?

• A. Simultaneous stroke and heart attack
• B. Simultaneous clotting and bleeding
• C. Simultaneous clotting and insulin release
• D. Simultaneous bleeding and vomiting

Correct answer: B

Rationale: Disseminated intravascular coagulation (DIC) is characterized by simultaneous clotting and bleeding throughout the body. This imbalance in the body's clotting system leads to the formation of blood clots in small blood vessels, which can consume clotting factors and platelets, ultimately leading to excessive bleeding. Choices A, C, and D are incorrect because they do not describe the characteristic feature of DIC, which involves both clotting and bleeding.

2. When starting on oral contraceptives, what key point should the nurse emphasize about taking the medication consistently?

• A. Oral contraceptives should be taken at the same time each day to maintain stable hormone levels and prevent pregnancy.
• B. Oral contraceptives can be taken at any time of day, as long as the schedule is consistent.
• C. Oral contraceptives should be taken in the morning to avoid nighttime side effects.
• D. Oral contraceptives are effective immediately upon starting, regardless of timing.

Correct answer: A

Rationale: When starting on oral contraceptives, it is crucial to take them at the same time each day to maintain stable hormone levels and ensure their effectiveness in preventing pregnancy. Choice B is incorrect because consistency in timing is essential to maximize contraceptive efficacy. Choice C is incorrect as there is no evidence that taking oral contraceptives in the morning helps avoid nighttime side effects. Choice D is incorrect because oral contraceptives do not provide immediate effectiveness and require consistent use to prevent pregnancy.

3. A patient has been prescribed raloxifene (Evista) for the prevention of osteoporosis. What effect should the nurse include in the teaching plan regarding the action of this medication?

• A. Decreases calcium excretion by the kidneys.
• B. Increases intestinal absorption of calcium.
• C. Stimulates bone formation by increasing osteoblast activity.
• D. Selectively binds to estrogen receptors, decreasing bone resorption.

Correct answer: D

Rationale: The correct answer is D: Selectively binds to estrogen receptors, decreasing bone resorption. Raloxifene is a selective estrogen receptor modulator (SERM) that works by binding to estrogen receptors, thereby decreasing bone resorption. This action helps in the prevention and treatment of osteoporosis by preserving bone density. Choices A, B, and C are incorrect because raloxifene does not directly affect calcium excretion by the kidneys, intestinal absorption of calcium, or stimulate bone formation by increasing osteoblast activity.

4. Which of the following accurately describes the pathophysiology of asthma?

• A. Chronic inflammation of the bronchial lining
• B. Narrowing of the airway due to bronchoconstriction
• C. Damage to alveoli reducing lung elasticity
• D. Overproduction of mucus by the goblet cells

Correct answer: B

Rationale: The correct answer is B: "Narrowing of the airway due to bronchoconstriction." In asthma, there is an inflammatory response that leads to bronchoconstriction, causing the airways to narrow and making it difficult to breathe. Choice A is incorrect as chronic inflammation is a feature of asthma but not the primary pathophysiological mechanism. Choice C is incorrect as damage to alveoli is more characteristic of conditions like emphysema. Choice D is incorrect as overproduction of mucus is a feature of chronic bronchitis, not asthma.

5. Which of the following are risk factors for hypertension (HTN)?

• A. High sugar, low-fat diet
• B. Increased physical activity
• C. Tobacco use
• D. Low-fat diet

Correct answer: C

Rationale: Tobacco use is a well-established risk factor for hypertension (HTN) as it can lead to increased blood pressure. High sugar intake and low-fat diets, as well as increased physical activity, are not directly associated with hypertension. While low-fat diets are generally recommended for overall health, they are not specifically linked to hypertension risk.
