Correct Answer: C

Rationale: Rationale: 1. Intermittent Mandatory Ventilation (IMV) allows the patient to breathe spontaneously between the preset mechanical breaths. 2. It provides a set number of breaths per minute while allowing the patient to initiate additional breaths at their own tidal volume. 3. IMV is a partial ventilatory support mode, providing a balance between controlled and spontaneous breathing. 4. Assist/Control Ventilation (A) provides full support with every breath initiated by the patient or the ventilator. 5. Controlled Ventilation (B) does not allow for spontaneous breaths by the patient. 6. Positive End-Expiratory Pressure (D) is a separate mode focusing on maintaining positive pressure at the end of expiration, not providing breaths.

Correct Answer: C

Rationale: The correct answer is C (80 mL/hour) because the minimum acceptable urine output for a patient is approximately 0.5-1 mL/kg/hour. For a 75 kg patient, this equates to 37.5-75 mL/hour. Therefore, an output of 80 mL/hour is within this range and is considered minimally acceptable. A: Less than 30 mL/hour is incorrect because it is below the recommended range for a 75 kg patient. B: 37 mL/hour is close to the lower end of the acceptable range, but it is not the minimum acceptable output. D: 150 mL/hour is above the recommended range and would be considered excessive for a 75 kg patient.

Correct Answer: D

Rationale: The Venturi mask is the best choice for delivering 65% oxygen because it allows precise oxygen concentration delivery through adjustable venturi valves. This device ensures consistent oxygen levels even during variations in patient breathing patterns. Face mask with non-rebreathing reservoir (A) delivers higher oxygen concentrations, low-flow nasal cannula (B) is not suitable for precise oxygen delivery, and simple face mask (C) may not provide the desired oxygen concentration.

Correct Answer: A

Rationale: Step 1: Symptoms of weight loss, racing heart rate, and difficulty sleeping are common in hyperthyroidism. Step 2: Presence of moist skin, fine hair, prominent eyes, lid retraction, and staring expression are classic signs of Grave's disease, a type of hyperthyroidism. Step 3: Grave's disease is an autoimmune disorder where the thyroid gland is overactive, leading to excessive production of thyroid hormones. Step 4: Excess thyroid hormones increase metabolic rate, causing weight loss, racing heart rate, and insomnia. Step 5: Therefore, the findings described in the question are consistent with Grave's disease.

Correct Answer: B

Rationale: The correct answer is B: Administer oxygen as prescribed. Dyspnea in a hospice patient often indicates respiratory distress, and administering oxygen can help improve oxygenation and alleviate breathing difficulty. Positioning the patient flat on their back (A) may worsen dyspnea due to increased pressure on the diaphragm. Restricting fluid intake (C) is not appropriate as dehydration can exacerbate respiratory distress. Chest physiotherapy (D) may not be suitable for a hospice patient experiencing dyspnea as it can be physically taxing and may not address the underlying cause effectively.
