Nursing Elites

1. Which of the following is a sign of hypoglycemia?

• A. Rapid, deep breathing
• B. Increased urination
• C. Weakness and confusion
• D. High blood pressure

Correct answer: C

Rationale: The correct answer is C: Weakness and confusion. Hypoglycemia is characterized by low blood sugar levels, leading to inadequate glucose supply to the brain, resulting in symptoms like weakness and confusion. Choices A, B, and D are incorrect. Rapid, deep breathing is not typically a sign of hypoglycemia but can be seen in other conditions like respiratory issues. Increased urination is more commonly associated with conditions like diabetes mellitus, while high blood pressure is not a typical sign of hypoglycemia.

2. 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.

3. After a patient is exposed to a specific antigen, B cells will differentiate into:

• A. B cytotoxic cells
• B. Plasma cells
• C. Bursal cells
• D. Clonal equivalents

Correct answer: B

Rationale: After exposure to a specific antigen, B cells undergo differentiation into plasma cells. Plasma cells are responsible for producing antibodies in response to the antigen. Choice A ('B cytotoxic cells') is incorrect because B cells do not differentiate into cytotoxic cells; cytotoxic cells are typically associated with T cells. Choice C ('Bursal cells') is incorrect as bursal cells are specific to birds and not relevant to human immune responses. Choice D ('Clonal equivalents') is incorrect as it does not describe the differentiation process of B cells exposed to antigens.

4. What causes osteoporosis?

• A. Poor nutrition in infancy
• B. Regularly weight-bearing exercise
• C. Bone loss, frequently during aging
• D. Cerebral palsy and associated disorders

Correct answer: C

Rationale: The correct answer is C. Osteoporosis is commonly caused by bone loss that occurs with aging, leading to brittle bones. Choice A, poor nutrition in infancy, is not a direct cause of osteoporosis. Choice B, regularly weight-bearing exercise, actually helps in maintaining bone density and strength, reducing the risk of osteoporosis. Choice D, cerebral palsy and associated disorders, is not a common cause of osteoporosis.

5. A male patient with hypogonadism is receiving testosterone therapy. What is the most serious adverse effect the nurse should monitor for?

• A. Increased risk of breast cancer
• B. Increased risk of cardiovascular events
• C. Increased risk of liver dysfunction
• D. Increased risk of prostate cancer

Correct answer: B

Rationale: The correct answer is B: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events such as heart attacks and strokes, especially in older patients. Monitoring for signs and symptoms of cardiovascular issues is crucial when administering testosterone therapy. Choices A, C, and D are incorrect because testosterone therapy does not typically lead to an increased risk of breast cancer, liver dysfunction, or prostate cancer.
