Paraquat is one of the more interesting pulmonary toxicants, in part because it doesn’t have to be inhaled to produce severe lung injury.

Explain the mechanism of paraquat toxicity, including the role of metabolism and reactive oxygen species.

Describe the clinical signs and symptoms of paraquat poisoning.

Explain why the lung is a target organ for paraquat even if the route of exposure is ingestion.

Mr. Heyden, 72, is brought to the emergency room after an accident at his farm. The paramedics report that his left side was pinned beneath his tractor, and that when he was freed, his left lower quadrant appeared to be compressed. His blood pressure is 90/50 mm Hg and falling, and his heart rate is 116 beats/min. His pulse is thready. Mr. Heyden complains of pain in his left side and then loses consciousness.

1. Mr. Heyden's low blood pressure will trigger certain compensatory mechanisms. Which statement below best reflects the changes in hormone levels that will occur?

Mr. Heyden's ADH, aldosterone, and renin will increase.
Mr. Heyden's ADH and renin will decrease, and his aldosterone will increase.
Mr. Heyden's ADH will decrease, his aldosterone will increase, and his renin will be unchanged.
Mr. Heyden's ADH will increase, and his aldosterone and renin will decrease.

2. Mr. Heyden's blood K+ levels are high. Which of the following best explains his high K+ levels?

Mr. Heyden's increased secretion of aldosterone will cause his K+ levels to increase.
Mr. Heyden's damaged kidneys can no longer adequately remove K+ from his blood.
The loss of Mr. Heyden's spleen means that his aged and fragile erythrocytes are not being removed, and so are rupturing in his blood vessels and releasing K+.
Mr. Heyden's increased secretion of ADH will cause his K+ levels to increase.

Describe in detail the action of insulin. Be sure to include a description of what it is (what kind of biomolecule/class of hormone), how its secretion is regulated, where specifically it is secreted from, its general effects on body cells, and finally each of its specific effects (if it has any) on: skeletal muscle, the liver, adipose tissue, and blood glucose levels.

Kate, age 57 years, is experiencing severe rheumatoid arthritis in her wrists, fingers, and knees. The joints are quite inflamed, red, and swollen. She is sitting rigidly in a chair and refuses to put on a sweater, even though she is shivering, or let anyone touch her arms. She has been prescribed an analgesic and an anti-inflammatory drug, but her dose is not due for another hour. She is feeling nauseated, so she has not eaten for the past 8 hours.

Discuss the potential treatment strategies and medications involved to relieve the pain being experienced by the patient. Explain the complications of continued use of over the counter non-steroidal anti-inflammatory (NSAIDs) medications. What other medications are appropriate for this patient, and why?
