1. Which of the following describes the pathophysiology of exercise-induced asthma?

• A. Bronchospasm after exercise
• B. IgE-mediated inflammatory response to antigen
• C. Bronchoconstriction after ingesting high-allergen foods
• D. Increased mucus production due to a genetic mutation

Correct answer: A

Rationale: The correct answer is A: 'Bronchospasm after exercise.' Exercise-induced asthma involves the narrowing of the airways (bronchospasm) triggered by physical activity. This bronchospasm leads to symptoms such as coughing, wheezing, and shortness of breath. Choices B, C, and D are incorrect because exercise-induced asthma is not primarily caused by an IgE-mediated inflammatory response to an antigen, bronchoconstriction after ingesting high-allergen foods, or increased mucus production due to a genetic mutation.

2. A patient with a history of cardiovascular disease is being prescribed hormone replacement therapy (HRT). What should the nurse include in the patient education regarding the risks associated with HRT?

• A. HRT may increase the risk of cardiovascular events, including heart attack and stroke.
• B. HRT may decrease the risk of osteoporosis.
• C. HRT may increase the risk of venous thromboembolism.
• D. HRT may decrease the risk of breast cancer.

Correct answer: A

Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including heart attack and stroke, especially in patients with a history of cardiovascular disease. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it may increase the risk of certain conditions like venous thromboembolism, as mentioned in choice C. Choice D is also incorrect as HRT has been associated with a slight increase in the risk of breast cancer.

3. In a patient with chronic kidney disease and a hemoglobin level of 9 g/dL, which of the following treatments is most appropriate?

• A. Iron supplementation
• B. Erythropoiesis-stimulating agents
• C. Blood transfusion
• D. Vitamin B12 supplementation

Correct answer: B

Rationale: In chronic kidney disease, anemia commonly occurs due to decreased erythropoietin production. Erythropoiesis-stimulating agents, such as erythropoietin or darbepoetin, are the mainstay of treatment to stimulate red blood cell production. Iron supplementation is more appropriate for iron-deficiency anemia, not the anemia of chronic kidney disease. Blood transfusion is reserved for severe cases or acute blood loss. Vitamin B12 supplementation is indicated for megaloblastic anemia caused by vitamin B12 deficiency, not specifically in chronic kidney disease-related anemia.

4. What function does aldosterone serve in the body?

• A. Aldosterone causes a release of sodium from the body, decreases fluid volume, and decreases blood pressure
• B. Aldosterone causes a retention of sodium in the body, increases fluid volume, and increases blood pressure
• C. Aldosterone causes a release of sodium from the body, increases fluid volume, and decreases blood pressure
• D. Aldosterone enhances intracellular sodium production and lowers blood pressure

Correct answer: B

Rationale: Aldosterone functions by causing the retention of sodium in the body, which results in an increase in fluid volume and blood pressure. Choice A is incorrect because aldosterone actually promotes sodium retention rather than release. Choice C is incorrect as it states that aldosterone decreases fluid volume, which is not accurate. Choice D is incorrect because aldosterone does not enhance intracellular sodium production; instead, it primarily acts on sodium reabsorption in the kidneys.

5. A patient has suffered from several infections in the last 6 months and unexplained impaired wound healing. What assessment should the nurse prioritize?

• A. Assess for pain.
• B. Assess for nutritional deficiencies.
• C. Assess genetic tendency for infection.
• D. Assess for edema and decreased hemoglobin.

Correct answer: B

Rationale: In this scenario, the patient's history of multiple infections and impaired wound healing indicates a potential issue with their immune system and overall health. Therefore, the nurse should prioritize assessing for nutritional deficiencies. Proper nutrition is essential for a healthy immune response and wound healing. Assessing for pain (choice A) may be important but addressing the root cause of the recurrent infections and impaired wound healing is crucial. Genetic tendency for infection (choice C) would be a less immediate concern compared to assessing for nutritional deficiencies. Edema and decreased hemoglobin (choice D) are not the most relevant assessments based on the patient's symptoms.
