Correct Answer: D

Rationale: The correct answer is D because assessing for localized ischemia involves evaluating multiple factors. A: Assessing color and temperature helps determine perfusion. B: Checking capillary refill assesses circulation. C: Evaluating pulse rate indicates cardiac output. Doing all of the above provides a comprehensive assessment of arterial flow and potential ischemia. Other choices are incorrect as they do not cover all aspects necessary for a thorough assessment.

Correct Answer: A

Rationale: The correct answer is A: White patches on the tonsils. Group A streptococci infection commonly presents with exudative tonsillitis, characterized by the presence of white patches or pus on the tonsils. This is due to the inflammatory response triggered by the bacteria. Hypertrophied tonsils (B), hemorrhage in the tonsils (C), and bleeding in the tonsils (D) are less likely to be visual signs of a streptococcal infection and are more indicative of other conditions or complications. Therefore, white patches on the tonsils are the most specific visual sign associated with group A streptococci tonsillar infection.

Correct Answer: B

Rationale: The correct answer is B: Counseling about respite care options. This intervention is most appropriate as it addresses the issue of role strain by providing the family member with support and options for temporary relief from caregiving responsibilities. Respite care allows the family member to take a break and recharge, reducing stress and preventing burnout. A: Assisting with activities of daily living is important but may not directly address the underlying issue of role strain. C: Teaching range-of-motion exercises is beneficial for physical well-being but does not directly address the emotional and psychological impact of role strain. D: Consulting with a social worker may be helpful for additional support but may not provide immediate relief or practical solutions for the family member's role strain.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Statement C indicates a misunderstanding that medication can be stopped when feeling better, which is incorrect. 2. Hypertension is a chronic condition that often requires lifelong medication. 3. This demonstrates a lack of understanding regarding the necessity of long-term management. 4. Statements A, B, and D show knowledge about hypertension's effects, dietary management, and awareness, respectively. Summary: Statement C is incorrect as it suggests stopping medication, while statements A, B, and D show accurate understanding of hypertension.

Correct Answer: D

Rationale: The correct answer is D (Downward) because it helps to maintain a clear airway for effective mouth-to-mouth respiration. By holding the victim's chin downward, you can ensure proper alignment of the airway, allowing the tongue to fall forward and prevent obstruction. Holding the chin forward (Choice A) may cause the airway to close, holding it backward (Choice B) may strain the neck, and holding it sideward (Choice C) may not provide optimal airway alignment. Holding the chin downward is the most effective and safe method for providing mouth-to-mouth respiration.
