The nurse is caring for a client with a suspected pulmonary embolism. Which diagnostic test should the nurse anticipate?
Chest x-ray
Electrocardiogram
D-dimer blood test
Arterial blood gas
The Correct Answer is C
Choice A reason: Chest x-ray may show nonspecific findings in pulmonary embolism but is not diagnostic. D-dimer, a fibrin degradation product, is highly sensitive for detecting thrombosis, guiding further imaging like CT pulmonary angiography, making it the priority test in suspected cases.
Choice B reason: Electrocardiogram may show tachycardia or right heart strain in pulmonary embolism but is nonspecific. D-dimer is a sensitive screening test, indicating clot presence, which prompts definitive imaging, making it the preferred initial diagnostic step in suspected pulmonary embolism.
Choice C reason: D-dimer blood test is the most sensitive screening tool for pulmonary embolism, detecting fibrin degradation from clots. Elevated levels prompt CT pulmonary angiography for confirmation, guiding urgent treatment to prevent further embolization, making it the critical test to anticipate.
Choice D reason: Arterial blood gas may reveal hypoxemia in pulmonary embolism but is nonspecific, as other conditions cause similar findings. D-dimer is more diagnostic, identifying clot presence, guiding imaging, and ensuring timely intervention, making it the priority test in suspected cases.

Correct Answer is A
Explanation
Choice A reason: Frequent small meals reduce gastroesophageal reflux by minimizing gastric distension, which decreases pressure on the lower esophageal sphincter. This prevents acid reflux into the esophagus, alleviating heartburn and irritation, making it an effective dietary strategy for managing GERD symptoms.
Choice B reason: Switching to decaffeinated coffee and tea may reduce reflux triggers, as caffeine relaxes the lower esophageal sphincter. However, small meals are more effective, as they directly reduce gastric volume and sphincter pressure, providing broader symptom relief than caffeine avoidance alone.
Choice C reason: Avoiding milk and cream is relevant for some GERD patients, as high-fat foods delay gastric emptying, increasing reflux. However, frequent small meals address the root cause of reflux by reducing gastric pressure, making this a more universally effective strategy than specific food avoidance.
Choice D reason: Listing high-dairy snack foods reinforces avoidance but is less direct than recommending small meals. Dairy may trigger reflux in some, but frequent small meals broadly reduce gastric distension and sphincter pressure, offering a more immediate and effective GERD management strategy.
Correct Answer is A
Explanation
Choice A reason: Rinsing the mouth after using a corticosteroid inhaler prevents oral candidiasis, a common side effect from residual steroid deposition. This ensures safe asthma management, as fungal infections compromise adherence and health, making it the priority teaching point for proper inhaler use.
Choice B reason: Using the inhaler only during asthma attacks applies to rescue inhalers, not maintenance corticosteroids, which are used daily. This is incorrect, as rinsing the mouth is essential for corticosteroid inhalers to prevent oral thrush, ensuring safe and effective asthma control.
Choice C reason: Storing inhalers in a refrigerator is unnecessary and may degrade some medications. Room-temperature storage is standard. Rinsing the mouth after corticosteroid inhaler use is critical to prevent oral candidiasis, making it the priority teaching point for asthma management.
Choice D reason: Shaking the inhaler only once may be insufficient for proper aerosolization in some devices. Rinsing the mouth after corticosteroid inhaler use is the priority, as it prevents oral thrush, a significant side effect, ensuring safe and consistent asthma therapy.
