1. A client with a pneumothorax is receiving oxygen therapy. Which assessment finding would indicate that the treatment is effective?

A. Increased respiratory rate
B. Decreased oxygen saturation levels
C. Improved breath sounds on the affected side
D. Increased dyspnea and chest pain

Correct answer: C

Rationale: In a client with a pneumothorax receiving oxygen therapy, improved breath sounds on the affected side would indicate effective treatment. This finding suggests that the collapsed lung is re-expanding, allowing air to flow more freely in and out of the affected area. Choices A, B, and D are incorrect: Increased respiratory rate, decreased oxygen saturation levels, and increased dyspnea and chest pain are signs of ineffective treatment or worsening of the condition in a client with a pneumothorax.

2. Following the administration of her annual influenza vaccination, a health care worker remains at the clinic for observation due to pain at the injection site. What should the nurse recommend?

A. ASA
B. Acetaminophen
C. Meperidine (Demerol)
D. Heat application

Correct answer: B

Rationale: The correct recommendation for pain at the injection site after an influenza vaccination is Acetaminophen. Acetaminophen is a suitable choice for managing mild to moderate pain and fever commonly associated with vaccinations. Choice A, ASA (aspirin), is not recommended due to the risk of Reye's syndrome in children and teenagers following viral illnesses. Choice C, Meperidine (Demerol), is a potent opioid analgesic and is not typically indicated for mild pain relief. Choice D, heat application, is not the standard recommendation for pain at an injection site and may not provide adequate relief.

3. Cushing syndrome is characterized by which disorder?

A. Hypocortisolism
B. Exophthalmos
C. Hypercortisolism
D. Hyperpigmentation

Correct answer: C

Rationale: Cushing syndrome is characterized by hypercortisolism, which is an excessive amount of cortisol in the body. Choice A, 'Hypocortisolism,' is incorrect as Cushing syndrome is associated with elevated cortisol levels. Choice B, 'Exophthalmos,' refers to bulging eyes and is not a characteristic feature of Cushing syndrome. Hyperpigmentation, as mentioned in choice D, can be present in Cushing syndrome due to increased ACTH levels stimulating melanocytes, but it is not the defining characteristic of the syndrome.

4. What are the characteristics of the inflammatory process?

A. Loss of function, coolness
B. Pain, redness
C. Heat, pallor
D. Swelling, pallor

Correct answer: B

Rationale: The correct answer is B: Pain, redness. Inflammation is characterized by pain and redness as part of the body's response to tissue injury. Choice A, loss of function and coolness, are not primary characteristics of inflammation. Choice C, heat and pallor, may be present in some cases but are not as consistently associated with inflammation as pain and redness. Choice D, swelling and pallor, includes swelling which is common in inflammation but pallor is not a typical characteristic.

5. Inflammatory exudates are a combination of several types. Which of the following exudates is composed of a large accumulation of leukocytes?

A. Serous
B. Purulent
C. Fibrinous
D. Hemorrhagic

Correct answer: B

Rationale: The correct answer is B: Purulent. Purulent exudates, or pus, consist primarily of leukocytes and dead cells, indicating a bacterial infection. Serous exudates contain a thin, watery fluid with few leukocytes. Fibrinous exudates are rich in fibrin and are commonly seen in severe inflammation. Hemorrhagic exudates contain red blood cells due to blood vessel damage.
