Which therapy is effective for treating sleep problems, stress, and seasonal affective disorders?

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 because the dull sound over the ribs is a normal finding due to the presence of underlying solid structures such as the liver or spleen. Repositioning the hands or using more force is unnecessary as it won't change the nature of the sound. Referring the patient for additional investigation (choice D) is not warranted as this finding is commonly expected during percussion over the ribs.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In ARDS, the primary issue is hypoxemia due to impaired gas exchange in the lungs. Administering oxygen helps to increase the oxygen levels in the blood, improving oxygenation to vital organs. Corticosteroids (B) are not indicated as they have not shown consistent benefit in ARDS treatment. Bronchodilators (C) are not effective as ARDS is not primarily a bronchoconstrictive disorder. Applying an ice pack to the chest (D) is not relevant and will not address the underlying hypoxemia. Administering oxygen is the most effective and essential intervention to correct hypoxemia in ARDS.

Correct Answer: A

Rationale: Administering aspirin is the most appropriate intervention for a client experiencing a heart attack. Aspirin helps prevent blood clot formation, which is crucial in reducing further damage to the heart during a heart attack. It inhibits platelets from clumping together, improving blood flow to the heart muscle. Thrombolytics are used to dissolve existing blood clots, but aspirin is more preventive. Monitoring for arrhythmias is important but not the initial intervention. Administering morphine can be considered for pain relief but is not as crucial as administering aspirin to prevent further clot formation.

Correct Answer: D

Rationale: The correct answer is D: Colace. When a client is immobilized and experiencing constipation, a stool softener like Colace is appropriate to prevent straining and discomfort. Advil and Anasaid are pain relievers, not laxatives. Clinocil is not a recognized medication. Colace is the best choice to address constipation in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Administer fluids. Administering fluids is the priority when caring for a client receiving a blood transfusion to prevent circulatory overload. Vital signs (A) should be monitored before and after the transfusion but are not the priority. Monitoring for transfusion reactions (C) is important but comes after administering fluids. Obtaining a blood sample (D) is not a priority during a blood transfusion. Administering fluids ensures adequate hydration and prevents complications during the transfusion process.

Correct Answer: A

Rationale: The correct answer is A (Broccoli, oranges, dark greens) because these foods are high in soluble fiber, antioxidants, and plant sterols which are known to help lower cholesterol levels. Broccoli contains fiber that binds to cholesterol in the gut, oranges are rich in vitamin C and fiber, and dark greens like spinach and kale are packed with antioxidants and fiber. Option B (Fiber-rich foods) is partially correct as fiber can help reduce cholesterol levels, but it is not as specific as the foods mentioned in option A. Option C (Increase intake of omega-3 fatty acids) is not directly related to lowering cholesterol, although omega-3s have other health benefits. Option D (Eliminate fat-rich foods) is not ideal as not all fats are bad for cholesterol, and some healthy fats like those found in avocados and nuts can actually improve cholesterol levels.

Correct Answer: C

Rationale: The correct answer is C because monitoring kidney function with regular laboratory tests is crucial in managing CKD. Regular testing helps identify changes in kidney function early, allowing for timely interventions to prevent complications. Administering diuretics (choice A) may worsen kidney function. Encouraging weight loss (choice B) may be necessary, but monitoring kidney function takes precedence. Encouraging the patient to limit fluid intake (choice D) may be necessary in some cases, but it is not the priority intervention.

Correct Answer: A

Rationale: The correct answer is A: Administer antiemetics. This intervention helps to reduce nausea and vomiting by blocking the neurotransmitters responsible for triggering these symptoms. Administering antiemetics is the most direct and effective approach to address severe nausea and vomiting post-surgery. Choice B (Placing the client in a supine position) is incorrect because it does not directly address the underlying cause of nausea and vomiting. Choice C (Providing hydration) is important but may not alleviate the symptoms of severe nausea and vomiting. Choice D (Monitoring bowel sounds) is important for assessing gastrointestinal motility but does not directly address the immediate symptoms of nausea and vomiting.
