test bank for health assessment

Correct Answer: B

Rationale: Rationale: 1. pH within normal range (7.35-7.45) indicates homeostasis. 2. PO2 (normal 75-100 mmHg) and PCO2 (normal 35-45 mmHg) are slightly deviated but not clinically significant. 3. HCO3 within normal range (22-26 mEq/L) further supports overall balance. Summary: A: Incorrect - HCO3 level is within normal range, ruling out metabolic alkalosis. C: Incorrect - PCO2 is within normal range, ruling out respiratory acidosis. D: Incorrect - PCO2 is slightly low but not significantly, ruling out respiratory alkalosis. Overall, the ABG values indicate the body is in homeostasis.

Correct Answer: D

Rationale: A focused assessment is more in-depth on specific issues, providing detailed information on a particular problem or concern. This allows for targeted interventions and treatment strategies. In contrast, a comprehensive assessment covers the body head to toe and involves all body systems, which may not be necessary when focusing on a specific issue. Occurring only in the clinic is a limitation to choice B, as assessments can be conducted in various settings. Involving all body systems, as stated in choice C, is not the primary focus of a focused assessment.

Correct Answer: A

Rationale: The correct answer is A: coma. High ammonia levels can lead to hepatic encephalopathy, causing impaired brain function and potentially leading to coma. Edema (B) is typically associated with fluid retention, not high ammonia levels. Hypoxia (C) is a condition of low oxygen levels, not directly related to high ammonia levels. Polyuria (D) is excessive urination, which is not a common sign of high ammonia levels.

Correct Answer: B

Rationale: The correct answer is B: Tenderness, warmth, and swelling at the site. Post-operative wound infection often presents with localized tenderness, warmth, and swelling due to inflammation and immune response. Redness, heat, and purulent drainage (choice A) can also indicate infection but are not specific to wound infections. Excessive swelling and redness (choice C) may be present in inflammatory responses but do not specifically point to an infection. Fever, chills, and nausea (choice D) can be systemic signs of infection but are not specific to wound infections. Tenderness, warmth, and swelling are more indicative of a localized wound infection.

Correct Answer: A

Rationale: The correct answer is A, contusion. A contusion is a soft-tissue injury caused by blunt force resulting in bruising, without breaking the skin. This is different from the other choices. Strain (B) refers to an injury to a muscle or tendon due to overstretching. Sprain (C) is an injury to a ligament from overstretching. Dislocation (D) involves the displacement of bones at a joint, not a soft-tissue injury. Therefore, the term that specifically aligns with a soft-tissue injury from blunt force is contusion.
