Nursing Elites

1. A 21-year-old male is brought to the ED following a night of partying in his fraternity. His friends found him 'asleep' and couldn't get him to respond. They cannot recall how many alcoholic beverages he drank the night before. While educating a student nurse and the man's friends, the nurse begins by explaining that alcohol is:

• A. A water-soluble compound that is easily absorbed by the gastric lining of the stomach.
• B. Very lipid-soluble and rapidly crosses the blood–brain barrier.
• C. Able to reverse the transport of some substances to remove them from the brain.
• D. Very likely to cause sedation and therefore the client just needs to sleep it off.

Correct answer: B

Rationale: The correct answer is B. Alcohol is very lipid-soluble and rapidly crosses the blood–brain barrier, leading to its effects on the central nervous system and causing symptoms like sedation and unconsciousness. Choice A is incorrect because alcohol is not water-soluble; it is lipid-soluble. Choice C is incorrect as alcohol does not reverse the transport of substances from the brain. Choice D is incorrect as sedation from alcohol is not a reason to just 'sleep it off' in cases of alcohol poisoning, which can be life-threatening and requires medical attention.

2. A 30-year-old man has a history of heart transplant and is receiving long-term steroids to prevent rejection. The patient is due for routine vaccines. Attenuated vaccines are contraindicated in this patient because the antigen is:

• A. live and can cause infection.
• B. mutated and infectious.
• C. inactive but still infectious
• D. pathogenic

Correct answer: A

Rationale: The correct answer is A: live and can cause infection. Patients who are immunocompromised, like those receiving long-term steroids after an organ transplant, should not receive live vaccines because the live attenuated organisms in these vaccines can cause infections in individuals with weakened immune systems. Choice B is incorrect because attenuated vaccines are live but weakened, not mutated. Choice C is incorrect because while inactive, attenuated vaccines are not infectious. Choice D is incorrect because attenuated vaccines are not pathogenic; they are attenuated (weakened) forms of the pathogen.

3. 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.

4. Which of the following are characteristic, localized cardinal signs of acute inflammation? (Select ONE that does not apply.)

• A. Redness
• B. Fatigue
• C. Swelling
• D. Warmth

Correct answer: B

Rationale: The correct answers are A, C, and D. Redness, swelling, and warmth are classic signs of acute inflammation. Redness occurs due to increased blood flow, swelling is caused by leakage of fluid into tissues, and warmth is due to the vasodilation and increased blood flow in the affected area. Fatigue is not a cardinal sign of acute inflammation and is not directly associated with the inflammatory response.

5. What typically causes contact dermatitis?

• A. Fungal infection
• B. Long-term disorder from gout
• C. Contact with a skin allergen
• D. Staphylococcal infection

Correct answer: C

Rationale: Contact dermatitis is typically caused by contact with a skin allergen that triggers an allergic reaction. Choice A, fungal infection, is incorrect as contact dermatitis is not caused by fungi. Choice B, long-term disorder from gout, is also incorrect as gout is not typically associated with contact dermatitis. Choice D, Staphylococcal infection, is incorrect as contact dermatitis is primarily an allergic reaction rather than a bacterial infection.
