A client who weighs 176 pounds is admitted to the intensive care unit with a serum glucose level of 600 mg/dL (33.3 mmol/L). Regular insulin at a rate of 0.1 unit/kg/hour is prescribed. The pharmacy provides a solution of regular insulin 100 units/100 mL of normal saline.

The nurse should set the infusion pump to deliver how many mL/hours?

Choice A reason: Crackles or coarse rales are typically associated with fluid in the airways, such as in cases of congestive heart failure or pneumonia, but they do not directly indicate a pleural effusion.

Choice B reason: A pleural friction rub is associated with pleuritis, where the inflamed pleurae rub against each other. It does not indicate decreased air flow in a specific lobe.

Choice C reason: Low pitched, sonorous rhonchi are related to secretions in the larger airways and are not specific to a pleural effusion or decreased air flow in one lobe.

Choice D reason: Diminished breath sounds in the left upper lobe are consistent with a pleural effusion, as the fluid can reduce air flow and sound transmission in that area. This finding directly correlates with the x-ray results showing decreased air flow in the entire left upper lobe.

Choice A reason: Petechial haemorrhage under the client's eyes can be a sign of various conditions, including increased intrathoracic pressure from vomiting. However, it is not the most urgent finding in this scenario. The nurse should focus on the finding that indicates a potential life-threatening condition.

Choice B reason: Right lower abdomen rebound tenderness is a sign of peritonitis, which can be caused by appendicitis or other serious abdominal conditions. This is an urgent finding that requires immediate medical attention, as it indicates inflammation of the peritoneum and potential risk of perforation or severe infection.

Choice C reason: Severe headache with photosensitivity can be associated with conditions such as meningitis or migraines. While concerning, it does not take precedence over the abdominal signs that indicate a potentially life-threatening condition like peritonitis.

Choice D reason: Dark green coloured emesis can be indicative of bile or upper gastrointestinal content, which might be seen in conditions such as intestinal obstruction or vomiting. However, it is not as urgent as the finding of rebound tenderness, which suggests an acute and severe abdominal condition that needs immediate intervention.
