One sign that a person is in shock is
- A. Flushed or reddish skin
- B. Decreased pulse and respiration rates
- C. Increased blood pressure
- D. Extreme thirst
Correct Answer: D
Rationale: The correct answer is D: Extreme thirst. In shock, the body redirects blood flow away from non-essential organs, leading to decreased blood supply to tissues. This triggers a release of stress hormones, causing increased thirst as the body tries to maintain fluid balance. Flushed skin (A) may indicate fever or heat exposure, not necessarily shock. Decreased pulse and respiration rates (B) are signs of severe shock, not an early indicator. Increased blood pressure (C) is typically not a sign of shock but can occur in certain types of shock.

If a nursing assistant feels it is not safe to move a resident by himself, he should
- A. Find a coworker to help
- B. Move the resident anyway because everyone else is probably busy
- C. Refuse to move the resident
- D. Ask the resident to move himself
Correct Answer: A
Rationale: The correct answer is A because it prioritizes resident safety by seeking assistance when unsure. Finding a coworker to help ensures safe transfer of the resident without risking injury. Refusing to move the resident (C) may delay necessary care. Moving the resident alone (B) disregards safety concerns. Asking the resident to move themselves (D) is not appropriate as they may not be capable or it may lead to harm.
During which of the following procedures must a nursing assistant always wear gloves?
- A. Shaving a resident
- B. Combing or brushing hair
- C. Dressing a resident
- D. Turning a resident
Correct Answer: A
Rationale: The correct answer is A: Shaving a resident. Gloves must be worn during shaving to prevent the transmission of infections through cuts or broken skin. Shaving involves contact with blood, which poses a risk of infection. The other choices (B: Combing or brushing hair, C: Dressing a resident, D: Turning a resident) do not involve direct contact with bodily fluids or broken skin, so gloves are not necessary for these procedures. It is essential to maintain proper hygiene practices to ensure the safety and well-being of the residents.
Both the _____ and _____ pulses are used in taking blood pressure.
- A. Radial and apical
- B. Apical and brachial
- C. Radial and brachial
- D. Brachial and femoral
Correct Answer: C
Rationale: The correct answer is C: Radial and brachial. Radial pulse is commonly used for a quick assessment of blood pressure, while brachial pulse is used with a blood pressure cuff for accurate measurement. Radial and apical pulses do not directly relate to blood pressure. Apical and brachial pulses are not typically used together for blood pressure measurement. Brachial and femoral pulses are not commonly used for taking blood pressure in clinical practice.

Which one of the following signs necessitates a definitive airway in severe trauma patients?
- A. Facial lacerations
- B. Repeated vomiting
- C. Severe maxillofacial fractures
- D. Sternal fracture
Correct Answer: C
Rationale: Correct Answer: C - Severe maxillofacial fractures
Rationale:
1. Severe maxillofacial fractures can compromise the airway due to obstruction or displacement of structures.
2. Airway management is crucial in trauma patients to ensure adequate oxygenation and ventilation.
3. Maxillofacial fractures can lead to airway compromise rapidly, requiring a definitive airway intervention.
4. Other choices (A: Facial lacerations, B: Repeated vomiting, D: Sternal fracture) may not directly impact the airway to the same extent as severe maxillofacial fractures.
