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.

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: Inform the physician immediately. This is important because finding a lump in the breast could be a sign of breast cancer, so prompt medical evaluation is crucial. Checking after the next menstrual cycle (B) may delay diagnosis and treatment. Squeezing the nipple (C) can cause harm and is not a reliable method for assessing a lump. Using a heating pad (D) is not recommended as it may mask symptoms and delay proper evaluation. Early detection and intervention are key in improving outcomes for breast cancer.

Correct Answer: A

Rationale: The correct answer is A: Use parallel bars or a walker. Before a client with impaired physical mobility gets up, the nurse should provide assistive devices like parallel bars or a walker to ensure safe and supported ambulation. This helps prevent falls and promotes independence. Using incontinence pads (B) is not directly related to mobility. Applying an abdominal binder (C) is not necessary before the client gets up. Using a footboard (D) is more relevant for positioning in bed, not for assisting with ambulation.

Correct Answer: A

Rationale: The correct answer is A: Fluid intake of less than 2,500mL. In diabetes insipidus, the body cannot properly regulate fluid balance, leading to excessive thirst and urination. Successful treatment aims to manage these symptoms by reducing fluid intake to prevent dehydration. Therefore, a decrease in fluid intake indicates successful treatment. Explanation for incorrect choices: B: Blood pressure of 90/50mmHg - Blood pressure is not directly related to the treatment of diabetes insipidus. C: Pulse rate of 126 beats/min - Pulse rate is not a specific indicator of successful treatment for diabetes insipidus. D: Urine output of more than 200mL/hour - In diabetes insipidus, excessive urine output is a symptom of the condition, so an increase in urine output does not indicate successful treatment.
