Correct Answer: B

Rationale: The correct answer is B: Use a low-pitched voice. This is because elderly individuals often experience age-related hearing loss, especially in high frequencies. Using a low-pitched voice helps improve the clarity and understanding of communication. Incorrect choices: A: Leaning and shouting can be perceived as aggressive and disrespectful to the elderly client. C: Opening the mouth wide while talking does not enhance communication and might be seen as patronizing. D: Using a medium-pitched voice may still be difficult for the elderly client to hear clearly due to age-related hearing loss.

Correct Answer: B

Rationale: The correct answer is B: Focused assessment. In this scenario, the nurse is continuously monitoring specific aspects such as vital signs, pupils, and orientation at regular intervals, which is characteristic of a focused assessment. This type of assessment allows the nurse to gather specific data related to the client's condition and respond promptly to any changes. A: Initial assessment is conducted upon admission to establish baseline data. C: Time-lapsed reassessment involves comparing current data to previous assessments over a longer period. D: Emergency assessment is performed in urgent situations to quickly identify life-threatening issues. By systematically assessing the client's vital signs, pupils, and orientation at frequent intervals, the nurse can provide timely and appropriate care in the intensive care unit setting.

Correct Answer: A

Rationale: The correct answer is A: abdominal pain related to decreased peristalsis. Ulcerative colitis causes inflammation and ulcers in the colon, leading to abdominal pain due to decreased peristalsis. This impairs the movement of stool through the colon, resulting in pain. Choice B is incorrect as diarrhea is a common symptom of ulcerative colitis, not hyperosmolar intestinal contents. Choice C is incorrect as ulcerative colitis often leads to diarrhea and not fluid volume excess. Choice D is incorrect as activity intolerance is not directly related to ulcerative colitis, whereas abdominal pain is a common symptom associated with the condition.

Correct Answer: D

Rationale: The correct answer is D: Hypocalcemia. Severe diarrhea can lead to electrolyte imbalances, including low calcium levels. Decreased muscle tone and deep tendon reflexes are classic signs of hypocalcemia. Calcium is essential for proper muscle function and nerve transmission. Hypernatremia (A) is high sodium levels, not related to decreased muscle tone. Hyperchloremia (B) is high chloride levels, not associated with muscle tone changes. Hypokalemia (C) is low potassium levels, which can cause muscle weakness but not specifically decreased muscle tone and deep tendon reflexes like hypocalcemia.

Correct Answer: C

Rationale: The correct answer is C: Acute pain. The patient's right femur fracture would likely cause significant pain. Treating the pain is a priority to ensure the patient's comfort and promote healing. Posttrauma syndrome (A) is more applicable for patients experiencing emotional distress following a traumatic event. Constipation (B) may be a concern due to immobility but is not as immediate as managing pain. Anxiety (D) may be present but addressing the acute pain would likely alleviate some anxiety as well.
