1. Select the stage of shock that is accurately paired with its characteristic.

• A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
• B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
• C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
• D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.

2. Which skin disorder most closely resembles and mimics dandruff?

• A. Lice infestation
• B. Scabies
• C. Dermatitis
• D. Acne vulgaris

Correct answer: C

Rationale: Dermatitis can closely resemble and mimic dandruff due to similar symptoms like flaking and itching. Lice infestation (choice A) is characterized by the presence of lice and their eggs attached to the hair shaft, different from dandruff. Scabies (choice B) is a contagious skin condition caused by mites, presenting as burrows, rashes, and intense itching, not typically resembling dandruff. Acne vulgaris (choice D) is a skin condition involving hair follicles and sebaceous glands, manifesting as pimples and inflammation, which is distinct from dandruff.

3. Select the cranial nerve that is accurately paired with its name.

• A. The fourth cranial nerve: The trochlear nerve
• B. The twelfth cranial nerve: The hypoglossal nerve
• C. The tenth cranial nerve: The olfactory nerve
• D. The thirteenth cranial nerve: The auditory nerve

Correct answer: B

Rationale: The twelfth cranial nerve is the hypoglossal nerve, which controls the muscles of the tongue. The other choices are incorrect because the trochlear nerve is the fourth cranial nerve responsible for eye movement, the olfactory nerve is the first cranial nerve responsible for the sense of smell, and there are only twelve cranial nerves, so there is no thirteenth cranial nerve.

4. Select the stage of viral hepatitis that is accurately paired with its characteristic(s).

• A. The prodromal stage: Jaundice begins
• B. The icteric stage: Flu-like symptoms occur
• C. The pre-icteric stage: Elevated urine bilirubin levels
• D. The post-icteric stage: Jaundice and dark urine occur

Correct answer: D

Rationale: The post-icteric stage of viral hepatitis is accurately described as the stage where jaundice and dark urine occur due to the accumulation of bilirubin. The resolution of jaundice and normalization of urine color are seen in this stage. Choices A, B, and C are incorrect. In the prodromal stage, symptoms like fatigue and malaise appear before jaundice. The icteric stage is characterized by jaundice, not flu-like symptoms. The pre-icteric stage does not typically involve elevated urine bilirubin levels, as this occurs after the icteric stage.

5. What is the main purpose of quality improvement in healthcare?

• A. To increase healthcare costs
• B. To improve patient outcomes
• C. To decrease patient satisfaction
• D. To increase hospital stays

Correct answer: B

Rationale: The main purpose of quality improvement in healthcare is to improve patient outcomes by enhancing the quality and safety of healthcare services. Choice A is incorrect because the goal is not to increase healthcare costs but to optimize resources and provide cost-effective care. Choice C is incorrect as the aim is to increase patient satisfaction through better outcomes. Choice D is incorrect as the objective is to reduce hospital stays by improving care efficiency and effectiveness.
