The nurse asked Mr. Gary his care preferences. This is an example of?

Correct Answer: A

Rationale: Asking care preferences is patient-centered care (A) needs focus, per definition. Holistic (B) whole, promotion (C) well-being, informatics (D) tech not preference-specific. A fits the nurse's priority on Mr. Gary's wishes, making it correct.

Correct Answer: B

Rationale: PPOs offer flexible provider options (B), per definition e.g., wider choice for Mr. Gary. Not no choice (A), not rule (C), not task (D) insurance-based. B best defines PPOs' flexibility, balancing cost and access, making it correct.

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 Tetanus antitoxin is outdated.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.

Correct Answer: D

Rationale: Hyperventilation lowers CO2, causing respiratory alkalosis, which binds calcium (hypocalcemia) and lowers phosphate (hypophosphatemia), risking seizures. Hyperphosphatemia doesn't occur phosphate drops with alkalosis. Nurses manage breathing rates, correcting pH and electrolytes to prevent tetany or convulsions, understanding these metabolic shifts.
