A client with type 1 diabetes mellitus is experiencing a hypoglycemic episode. The healthcare provider prescribes glucagon 1 mg intramuscularly STAT before an intravenous site is established. The medication is available in 1 mg vial. The instructions for reconstitution state "Add 1 mL of sterile water for injection." How many mL should the nurse administer? (Enter numerical value only.)

Airborne transmission involves the spread of infectious droplets smaller than 5 micrometers that remain suspended in the air for prolonged periods. Effective containment requires a negative-pressure isolation room where air is filtered and exhausted outdoors to prevent pathogen migration into hospital corridors. Healthcare workers must utilize a fitted N95 respirator to prevent the inhalation of microscopic nuclei capable of reaching the distal alveoli.

Rationale:

A. Scarlet fever and bacterial pneumonia are transmitted via large droplets expelled through coughing or sneezing. These pathogens do not remain suspended in air and typically require droplet precautions, including a standard surgical mask. Negative airflow is not indicated for these conditions as they do not pose an airborne risk.

B. A positive Mantoux test and acid-fast bacillus in sputum are definitive indicators of active Mycobacterium tuberculosis. This pathogen is the classic example of an airborne threat necessitating a monitored negative-pressure environment and particulate respirators. Failure to implement these barriers allows the bacilli to circulate throughout the ventilation system.

C. Scabies is a parasitic infestation transmitted through direct skin-to-skin contact or contaminated linens. Management requires contact precautions, which include the use of gowns and gloves to prevent transmission to staff or other clients. Air filtration and specialized masks provide no benefit in preventing the spread of sarcoptes scabiei.

D. Herpes simplex II is a viral infection characterized by vesicular lesions and is spread primarily through direct contact with infected secretions. While highly contagious through touch, the virus is not aerosolized and does not require specialized respiratory protection. Standard and contact precautions are sufficient to manage the risk during an active outbreak.

Gouty arthritis is a metabolic disorder characterized by the accumulation of urate crystals in the joints, most commonly the first metatarsophalangeal joint or the ankle. This condition is driven by hyperuricemia, often triggered by the rapid breakdown of cells during sudden weight loss or the consumption of foods high in purines. In an acute flare, the joint becomes erythematous, edematous, and exquisitely sensitive to any mechanical pressure or movement.

Rationale:

A. Encouraging active range of motion is contraindicated during an acute gouty flare. The presence of needle-like uric acid crystals within the joint space causes significant mechanical friction and synovial inflammation. Physical activity or manipulation of the joint during this phase will exacerbate pain and potentially increase tissue damage. The joint should be immobilized and protected until the inflammation subsides.

B. Avoiding the consumption of wine and beer is a critical dietary instruction. Alcohol, particularly beer, is high in purines and interferes with the renal excretion of uric acid, significantly increasing the risk of recurrent attacks. While coffee was once debated, current evidence suggests it may actually lower urate levels; however, the restriction of alcohol is a foundational and high-priority intervention for managing gout.

C. Substituting natural fruit juices for carbonated drinks may be counterproductive if the juices are high in fructose. High fructose intake is associated with increased uric acid production and can trigger gout flares just as effectively as some high-purine foods. The nurse should instead encourage increased water intake to facilitate the dilution and renal clearance of uric acid crystals from the body.

D. Using an electric heating pad is inappropriate for an acute gout attack. Heat promotes local vasodilation, which can worsen the existing inflammatory edema and intensify the throbbing pain. Instead, cold applications (ice packs) are generally recommended during the acute phase to provide an analgesic effect and reduce the localized inflammatory response in the affected ankle.
