The diagnostic work-up of a client hospitalized with complaints of progressive weakness and fatigue confirms a diagnosis of myasthenia gravis. The medication used to treat myasthenia gravis is:

Correct Answer: A

Rationale: Prostigmin (neostigmine), a cholinesterase inhibitor, treats myasthenia gravis by enhancing neuromuscular transmission atropine counters side effects, Didronel is for bones, and Tensilon is diagnostic. Nurses administer it, monitoring for cholinergic crisis, key for symptom relief.

Correct Answer: B

Rationale: Fluid status in burn patients is critical due to massive losses from damaged skin. Electrolyte levels (choice A) indicate imbalances but not volume status directly. Hematocrit (choice B) measures blood concentration; in burns, it rises with hemoconcentration from plasma loss, making it a practical indicator of fluid shifts. Creatinine level (choice C) assesses kidney function, indirectly reflecting hydration over time, not acutely. Hemoglobin level (choice D) tracks oxygen-carrying capacity but is less sensitive to immediate fluid changes. B is correct, as hematocrit provides a rapid, reliable gauge of fluid resuscitation needs. Nurses use this, alongside urine output, to titrate IV fluids, preventing shock or overload in burn management.

Correct Answer: A

Rationale: Vaccines in children with convulsions require caution. DPT (choice A) contains pertussis, linked to rare febrile seizures post-vaccination; in children with uncontrolled seizures, it's contraindicated or delayed until stabilized, per AAP guidelines. Measles (choice B), typhoid (choice C), and BCG (choice D) don't carry this risk; measles may cause fever but not specifically seizures in this context. A is correct, reflecting DPT's precaution. Nurses assess seizure history, consult physicians, and may use DT instead, ensuring safe immunization.

Correct Answer: C

Rationale: An antibody-antigen reaction from a microorganism infection, like bacterial invasion, typically produces purulent exudates (C), rich in pus, neutrophils, and debris due to active immune response. Serous exudates (A) are clear and watery, seen in mild inflammation (e.g., blisters). Serosanguinous (B) is a mix of serum and blood, common in surgical wounds. Sanguinous (D) is bloody, linked to trauma or vessel damage, not infection-driven immunity. Purulent exudates reflect the body's fight against pathogens, as neutrophils engulf microbes, forming pus a hallmark of such reactions making C the accurate choice.

Correct Answer: D

Rationale: Martina is in a crisis (D). Her devastation, depression, and crying after losing at Wimbledon suggest a sudden, overwhelming event disrupting her homeostasis, fitting crisis definition. Stress (A) is too mild; anxiety (B) lacks the depth of her response. Exhaustion in GAS (C) follows prolonged stress, but this is acute. Crisis involves intense emotional distress from a specific trigger, like career setback, making D correct.
