The healthcare provider (HCP) prescribes diagnostic tests for a client whose chest x-ray indicates pneumonia. Which diagnostic test should the nurse review for implementation to guide the most therapeutic treatment of the pneumonia?
Blood cultures.
Computerized tomography (CT) of the chest.
Sputum culture and sensitivity.
Arterial blood gas (ABG).
The Correct Answer is C
Choice A reason: Blood cultures may help identify systemic infection but are less specific for guiding targeted treatment of pneumonia unless bacteremia is suspected.
Choice B reason: A CT scan provides detailed imaging and may help assess complications or unclear cases, but it does not identify the causative organism for therapeutic decisions.
Choice C reason: Sputum culture and sensitivity directly identify the pathogen responsible for pneumonia and determine which antibiotics are most effective, making it the most therapeutic diagnostic tool.
Choice D reason: ABG analysis evaluates respiratory function and acid-base balance but does not guide antimicrobial therapy.

Correct Answer is D
Explanation
Choice A reason: While notifying the provider is important, it is not the first action. The nurse must first identify the cause of the hypotension and symptoms before escalating.
Choice B reason: Lung sounds may be relevant if respiratory compromise is suspected, but the symptoms here point more toward circulatory instability.
Choice C reason: Ensuring IV fluids are running is supportive, but it does not directly address the potential cause of the hypotension and restlessness.
Choice D reason: Checking under the back for bleeding is the most immediate and targeted action. Postoperative hemorrhage is a common cause of hypotension and altered mental status, and identifying it quickly can be life-saving.
Correct Answer is B
Explanation
Choice A reason: Albumin levels are not directly affected by hydrocortisone therapy and are not a priority in monitoring Addison’s disease management.
Choice B reason: Glucocorticoids like hydrocortisone can increase serum glucose levels due to their effect on carbohydrate metabolism. Monitoring glucose is essential to detect hyperglycemia, especially in newly initiated therapy.
Choice C reason: Osmolarity may be indirectly influenced by adrenal hormones, but it is not the most specific or sensitive marker for hydrocortisone effects.
Choice D reason: Platelet levels are not typically impacted by hydrocortisone in the context of Addison’s disease and are not a priority for routine monitoring.
