Answer to Question 1

ANS: C
Tetanus results from an infection by the anaerobic spore-forming, gram-positive bacillus Clostridium tetani. The organism forms two exotoxins that affect the central nervous system to produce the clinical manifestations of the disease. Tetanus is not an inflammatory process. The toxin acts at the neuromuscular junction to produce muscular stiffness and to lower the threshold for reflex excitability. It is usually a systemic disease. Initial symptoms are usually a progressive stiffness and tenderness of the muscles of the neck and jaw. The sustained contraction of the jaw-closing muscles provides the name lockjaw. Meningeal inflammation is not the cause of the muscle spasms.

Answer to Question 2

ANS: C
Calcium gluconate is administered intravenously over 10 to 30 minutes or as a continuous infusion. If it is given more rapidly than this, cardiac dysrhythmias and circulatory collapse may occur. Early feedings are indicated, but when the ionized calcium drops below 3.0 to 4.4 mg/dL, intravenous calcium gluconate is necessary. Intramuscular or intraosseous administration is not recommended.
