test bank for health 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: A

Rationale: The correct answer is A: Monitor urine output. This is the most important action because it helps assess the client's fluid status and kidney function. Monitoring urine output can indicate if the client's body is effectively eliminating excess fluid. Elevating the head of the bed (B) helps with respiratory function but is not the priority in fluid overload. Administering diuretics (C) may be necessary but should be based on urine output monitoring. Encouraging deep breathing (D) is important for respiratory function but not directly related to managing fluid overload.

Correct Answer: B

Rationale: The correct action for a client with DVT in the leg is to apply compression and elevate the leg (Choice B). Compression helps prevent blood clots from moving and causing further complications. Elevating the leg reduces swelling and improves blood flow. Choice A is incorrect because applying heat can actually worsen DVT by promoting inflammation and increasing blood flow. Choice C is incorrect as massage can dislodge blood clots and lead to serious complications like pulmonary embolism. Choice D is incorrect as massaging the leg can be dangerous in DVT as mentioned before.

Correct Answer: B

Rationale: The given ABG values fall within normal ranges, indicating homeostasis. The pH is within the normal range (7.35-7.45), indicating acid-base balance. The PO2 is slightly lower but still within the normal range (80-100 mmHg). PCO2 falls within the normal range (35-45 mmHg), showing effective ventilation. The HCO3 level is also within the normal range (22-26 mEq/L), indicating proper kidney function. Therefore, all values are within normal limits, reflecting a state of homeostasis. Other choices are incorrect as they suggest imbalances in acid-base status, which is not seen with these values.

Correct Answer: D

Rationale: The correct answer is D: Administer diuretics. The priority for a nurse caring for a client with pneumonia is to maintain adequate oxygenation and prevent respiratory failure. Diuretics help reduce fluid overload in the lungs, improving gas exchange and oxygenation. Administering antibiotics (choice A) is important to treat the infection but not the top priority. Administering oxygen (choice B) is crucial for oxygenation, but diuretics take precedence to improve lung function. Administering corticosteroids (choice C) may be considered in certain cases to reduce inflammation, but it is not the primary priority.
