Correct Answer: A

Rationale: The correct answer is A: Light therapy. Light therapy is effective for treating sleep problems, stress, and seasonal affective disorders because exposure to bright light can regulate circadian rhythms, improve mood, and alleviate symptoms associated with these conditions. Light therapy helps reset the body's internal clock, promoting better sleep patterns and reducing stress. Exercise (choice B) can also improve sleep and reduce stress, but it may not specifically target seasonal affective disorders. Medication (choice C) and herbal treatments (choice D) are not typically recommended as the first-line treatment for these conditions and may have side effects or limited efficacy compared to light therapy.

Correct Answer: A

Rationale: The correct answer is A: Perform a lumbar puncture. This is the first action because diagnosing meningitis requires cerebrospinal fluid analysis obtained through a lumbar puncture. It helps identify the specific type of meningitis (bacterial, viral, or fungal) and guides appropriate treatment. Administering pain relief (B) or oxygen (C) may be necessary but not the initial priority. Administering antibiotics (D) should be based on the results of the lumbar puncture to ensure targeted therapy.

Correct Answer: B

Rationale: The correct answer is B: Deep vein thrombosis (DVT). Patients with a history of stroke are at increased risk for DVT due to immobility and vascular damage. Monitoring for DVT is crucial to prevent life-threatening complications like pulmonary embolism. Acute renal failure (A) is not directly related to stroke and is not a common complication. Pneumonia (C) may occur but is not the highest priority compared to DVT. Hypertension (D) is important to monitor but is not the priority in this case as DVT poses a more immediate risk to the patient's health.

Correct Answer: A

Rationale: The correct answer is A: Administer albuterol. Albuterol is a bronchodilator that helps open airways, making it effective in treating respiratory distress. It works quickly to relieve symptoms such as shortness of breath and wheezing. Corticosteroids (B) may be used in conjunction with albuterol for severe cases, but albuterol is the immediate intervention. Providing pain relief (C) is not the primary intervention for respiratory distress. Nebulizers (D) are a delivery method for medications like albuterol, but the key intervention is administering the medication itself.
