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 for why choice C is correct: 1. The lab value of K at 3.2 mEq/L indicates hypokalemia. 2. Digitalis can worsen hypokalemia and lead to toxicity. 3. Avoiding foods rich in potassium will prevent further lowering of potassium levels. 4. This intervention helps prevent potential digitalis toxicity in the client. Summary of why the other choices are incorrect: A. Stopping digitalis therapy abruptly can lead to rebound effects and worsen the condition. B. Trousseau's and Chvostek's signs are not relevant to the client's current lab values. D. While observing for digitalis toxicity is important, addressing the low potassium level is a more immediate concern in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Levodopa. Levodopa is the most effective pharmacologic agent for Parkinson's disease as it is converted to dopamine in the brain, replenishing dopamine levels which are depleted in Parkinson's. Selegiline and Symmetrel provide symptomatic relief but are not as effective as Levodopa. Permax is not commonly used due to its association with serious side effects like heart valve damage.

Correct Answer: D

Rationale: The correct answer is D: Hypovolemia and shock. Rationale: 1. Low blood volume leads to decreased blood pressure and rapid heart rate as compensatory mechanisms. 2. These signs indicate inadequate perfusion due to reduced blood volume. 3. Hypovolemia can progress to shock if not addressed promptly. Summary: A: Compression of blood vessels is not directly related to low blood volume. B: Increasing circulating blood volume would not occur in a client with low blood volume. C: Inadequate renal perfusion is a consequence of hypovolemia, not an implication of decreasing blood pressure and rapid heart rate.

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.
