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: B

Rationale: The correct answer is B: dominant health care culture. The scenario illustrates the influence of the dominant health care culture, where the daughter, as a dental hygienist, is advocating for her mother to follow the plan of care based on her professional knowledge and beliefs. This highlights the power dynamics and authority within the healthcare system, where individuals with certain expertise may exert influence over others, even family members. This is distinct from generational differences (A) which focus on age-related disparities, lack of respect for independence (C) which emphasizes autonomy and decision-making, and critical cultural perspective (D) which involves a deeper analysis of cultural influences on healthcare interactions.

Correct Answer: B

Rationale: The correct answer is B: Encourage fluid intake. Adequate hydration helps in pain management by promoting circulation and reducing inflammation. Opioids (choice A) should only be used if non-pharmacological interventions fail. Administering oxygen (choice C) is not typically indicated for pain management. Monitoring electrolyte levels (choice D) is important but not the most immediate intervention for acute pain post-surgery.

Correct Answer: A

Rationale: The correct approach is to defer the rest of the mental health examination. This is because the patient's symptoms of dysarthria and lethargy indicate a potential medical emergency or brain injury, which should take precedence over the mental health assessment. It is important to first ensure the patient's physical well-being before proceeding with the mental health evaluation. Choice B is incorrect as skipping the language portion of the examination may overlook crucial information related to the patient's condition. Choice C is also incorrect as an in-depth speech evaluation may delay necessary medical interventions. Choice D is incorrect as assuming dysarthria is always linked to severe depression can lead to overlooking urgent medical needs.

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: The correct answer is A: Administer antihypertensive medication. In a hypertensive emergency, the priority is to lower blood pressure quickly to prevent organ damage. Antihypertensive medications like nitroprusside or labetalol are used for this purpose. Placing the client in a comfortable position and administering oxygen (B) may be beneficial, but lowering the blood pressure is the primary action. Monitoring blood pressure and administering antihypertensive medication (C) is correct, but the emphasis should be on immediate intervention. Monitoring the client's ECG (D) is important but not the primary action in a hypertensive emergency.

Correct Answer: B

Rationale: The correct answer is B because a functional health assessment evaluates various health patterns such as roles, relationships, coping mechanisms, stress tolerance, and lifestyle choices, providing a holistic view of the individual's well-being. Vital signs and circulation (A) are typically included in a physical assessment, not a functional health assessment. Assessing specific organ abnormalities (C) would be part of a focused physical examination or diagnostic testing. Acute symptoms (D) are important to address but do not encompass the comprehensive evaluation of health patterns that a functional health assessment covers.

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: C

Rationale: The correct answer is C, BMI indicates obesity (35). To calculate BMI, we use the formula BMI = (Weight in pounds / (Height in inches x Height in inches)) x 703. Plugging in the values (216 / (66 x 66)) x 703, we get a BMI of approximately 35. A BMI of 35 falls within the obesity category (BMI 30 or higher). Choice A is incorrect because a BMI of 35 is not within normal limits. Choice B is incorrect as a BMI of 27 would indicate overweight status, not obesity. Choice D is incorrect as the BMI calculated is higher than normal, not lower.
