Correct Answer: C

Rationale: The correct answer is C, hyperglycemia and hypokalemia. Hyperglycemia can occur in adult clients due to various factors such as diabetes or stress. Hypokalemia can be a consequence of hyperglycemia or other conditions leading to potassium loss. Monitoring for these metabolic complications is essential to ensure the client's well-being. Other choices are incorrect because hypoglycemia and hypercalcemia (choice A) are less likely to occur concurrently in adult clients. Hyperglycemia and hyperkalemia (choice B) are less common as hyperkalemia is usually associated with renal dysfunction. Hyperkalemia and hypercalcemia (choice D) are less likely to be monitored together as they are not commonly seen in the same clinical context.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Dressing changes twice a day help maintain a clean wound environment, reducing the risk of infection. 2. Regular dressing changes promote proper wound healing by facilitating moisture balance and removal of dead tissue. 3. It is a direct intervention that addresses the patient's poor wound healing. 4. Teaching the patient about signs of infection (B) is important but does not directly address the wound healing process. 5. Instructing the family on dressing changes (C) is helpful but should not substitute direct patient care. 6. Refocusing the patient from body image changes (D) is not directly related to improving wound healing.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Corticotropin-secreting pituitary adenoma leads to excess adrenocorticotropic hormone (ACTH) production. 2. High corticotropin levels would be expected due to the adenoma's overproduction. 3. The high cortisol levels occur as a result of increased ACTH stimulating cortisol release from the adrenal glands. 4. Therefore, choice B (high corticotropin and high cortisol levels) is the correct answer. Summary: - Choice A is incorrect because low cortisol levels would not be expected in a client with a corticotrophin-secreting pituitary adenoma. - Choice C is incorrect because low corticotropin levels would not align with the excessive ACTH production from the adenoma. - Choice D is incorrect as both low corticotropin and low cortisol levels would not be consistent with the pathophysiology of a corticotrophin-secreting pituitary adenoma.

Correct Answer: C

Rationale: The nurse interprets this as respiratory alkalosis because the patient is likely experiencing hyperventilation, leading to a decrease in CO2 levels and respiratory alkalosis. This is indicated by an increase in pH and a decrease in PaCO2 on arterial blood gas analysis. Metabolic acidosis (choice B) is characterized by low pH and low bicarbonate levels, not seen in this scenario. Respiratory acidosis (choice A) is characterized by high PaCO2 levels and low pH, which is not the case here. Metabolic alkalosis (choice D) is characterized by high pH and high bicarbonate levels, which is not consistent with the patient's presentation.

Correct Answer: D

Rationale: The correct answer is D: Impaired gas exchange related to alveolar-capillary membrane changes. This nursing diagnosis is appropriate for a patient with pneumonia and lower lobe infiltrates as it directly addresses the underlying physiological issue of impaired gas exchange due to alveolar-capillary membrane changes. The infiltrates indicate infection and inflammation in the lower lobes, leading to difficulty in oxygen and carbon dioxide exchange. This diagnosis aligns with the patient's medical condition and helps guide nursing interventions focused on improving oxygenation. Choice A is incorrect because ineffective breathing pattern is a broad diagnosis that does not specifically address the gas exchange issue seen in pneumonia. Choice B is incorrect as the risk for infection is already present with the diagnosis of pneumonia and does not directly address the patient's current respiratory status. Choice C is incorrect as dehydration is not the primary concern in a patient with pneumonia and lower lobe infiltrates.
