Correct Answer: D

Rationale: The correct answer is D: Presence of laryngospasm. Laryngospasm is a serious complication of trauma to the upper airway that can lead to airway obstruction. Assessing for laryngospasm is crucial to ensure the client's airway remains patent. Pain when talking (A) is more related to vocal cord injury, increased nasal swelling (B) is a symptom of nasal trauma, and burning in the throat (C) may indicate pharyngeal injury, but laryngospasm (D) directly affects airway patency in upper airway trauma cases.

Correct Answer: B

Rationale: The correct answer is B: decrease resident intestinal flora. Lactulose is a synthetic sugar that is not absorbed in the intestine and is used to decrease ammonia levels in patients with hepatic encephalopathy by promoting the growth of beneficial gut bacteria that help metabolize ammonia. This action helps reduce the toxic effects of ammonia on the brain. A: prevent constipation - Lactulose may help with constipation, but its primary action in this scenario is to decrease resident intestinal flora. C: increase intestinal peristalsis - Lactulose does not directly increase peristalsis. D: prevent portal hypertension - Lactulose does not have a direct effect on preventing portal hypertension.

Correct Answer: C

Rationale: The correct answer is C (600ml/24hr) because insensible fluid losses in an afebrile person are typically around 600ml per 24 hours. Insensible losses include water lost through the skin as sweat and through the lungs during respiration. These losses are not easily quantifiable but are estimated to be around 600ml/day in normal circumstances. Choices A, B, and D are incorrect because they are either too low (A and B) or too high (D) compared to the normal range of insensible fluid losses. Selecting C as the correct answer is based on the understanding of physiological principles related to fluid balance and normal body functions.

Correct Answer: B

Rationale: The correct answer is B: Direct bilirubin level of 2 mg/dl. Acetaminophen toxicity can lead to liver damage, causing an increase in bilirubin levels. Direct bilirubin specifically indicates liver function. A: Sodium level is not related to acetaminophen toxicity. C: Prothrombin time is a measure of blood clotting, not indicative of acetaminophen toxicity. D: Platelet count is not affected by acetaminophen toxicity.

Correct Answer: A

Rationale: The correct answer is A: A-positive blood to an A-negative client. This is because in ABO blood typing, individuals with blood type A have anti-B antibodies in their plasma. Therefore, if A-positive blood (which contains the A antigen) is given to an A-negative client (who has anti-A antibodies), there is a high risk of an acute hemolytic reaction due to the antibodies attacking the transfused blood cells. Choices B, C, and D are incorrect because they do not involve a mismatch of ABO blood types that would lead to a significant risk of acute hemolytic reaction. In choice B, O-positive blood can be safely transfused to an A-positive client as O blood is considered the universal donor. In choice C, O-negative blood can be safely given to an O-positive client as O-negative blood is compatible with all blood types. In choice D, B-positive blood can be safely administered to an AB-positive client as the AB blood type can receive both
