Correct Answer: C

Rationale: Poor nutrition manifests in physical signs like dental caries (tooth decay), brittle hair (protein deficiency), and spongy gums (vitamin C deficiency). A deep red tongue with papillae is normal, not a malnutrition sign pallor or smoothness might indicate deficiency (e.g., B12). Nurses assess these cues to identify nutritional deficits, guiding dietary interventions to reverse symptoms and prevent complications like infection or delayed healing.

Correct Answer: D

Rationale: Tetanus immunoglobulin provides immediate passive immunity against *Clostridium tetani* in contaminated wounds, neutralizing toxins in unvaccinated patients. DTP (diphtheria, tetanus, pertussis) and tetanus toxoid build active immunity over time, unsuitable for acute cases. Tetanus antitoxin is outdated. Nurses administer immunoglobulin alongside toxoid for dual protection, preventing tetanus's lethal muscle spasms, critical in emergency settings.
