Correct Answer: C

Rationale: The correct immediate action for a client with a tracheostomy showing signs of respiratory distress is to suction the tracheostomy. Respiratory distress in this case is often caused by a blockage, which can be quickly relieved by suctioning to clear the airway. Increasing the suction setting on the ventilator (Choice A) may not address the immediate blockage in the tracheostomy. Administering a bronchodilator (Choice B) may help with bronchoconstriction but does not address the potential blockage in the tracheostomy. Encouraging deep breathing exercises (Choice D) may not be effective in relieving the immediate respiratory distress caused by a blocked tracheostomy.

Correct Answer: B

Rationale: The correct instruction that the nurse should include is to rotate injection sites with each dose. This practice is essential to prevent tissue damage and ensure proper insulin absorption. Option A is incorrect because insulin should not be injected into the muscle, but rather into the subcutaneous tissue. Option C is incorrect as insulin should be stored in the refrigerator to maintain its effectiveness. Option D is incorrect as massaging the injection site after administration can lead to faster absorption and potentially hypoglycemia.

Correct Answer: B

Rationale: The correct action for the nurse to take when caring for a client with schizophrenia experiencing auditory hallucinations is to ask the client directly what they are hearing. This approach helps the nurse gain insight into the client's experience, establish effective communication, and provide appropriate support. Encouraging the client to lie down in a quiet room (Choice A) may not address the hallucinations directly. Telling the client that the voices are not real (Choice C) can be invalidating and may lead to further distress. Providing headphones for music (Choice D) may not be effective in addressing the client's hallucinations.

Correct Answer: A

Rationale: Corrected Rationale: Dehydration in the elderly is often signaled by dry mouth, confusion, and decreased skin turgor due to reduced fluid intake. Choice A is the correct answer as these are common signs and symptoms of dehydration in the elderly.\nIncorrect Rationales: Option B (Increased heart rate and muscle cramps) are more associated with conditions like hyperthyroidism or electrolyte imbalances rather than dehydration. Option C (Fever, rapid breathing, and increased urine output) are signs of other medical conditions such as infections or diabetes insipidus. Option D (Increased thirst and difficulty walking) can be seen in various situations but are not specific signs of dehydration in the elderly.

Correct Answer: C

Rationale: The correct answer is C: 'Cut toenails straight across.' This instruction is crucial for clients with diabetes to prevent ingrown toenails and potential foot complications. Soaking feet in hot water daily (Choice A) can lead to skin damage and is not recommended for diabetic individuals. Using a heating pad on the feet daily (Choice B) can cause burns or injuries due to reduced sensation in the feet that often accompanies diabetes. Massaging feet with lotion daily (Choice D) is generally safe but may not address the specific preventive measure of cutting toenails correctly.
