What is the primary action when a client is experiencing a hypertensive emergency?

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: 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.

Correct Answer: A

Rationale: Step-by-step rationale: 1. High HDL cholesterol is associated with decreased cardiovascular disease risk. 2. HDL cholesterol helps remove LDL cholesterol from arteries, reducing plaque buildup. 3. This leads to lower risk of heart disease and stroke. 4. Low HDL cholesterol (choice B) is associated with increased risk. 5. Low total cholesterol (choice C) and low triglycerides (choice D) do not directly correlate with decreased cardiovascular disease risk. Summary: High HDL cholesterol is beneficial for cardiovascular health as it helps reduce plaque buildup in arteries. Low HDL cholesterol, low total cholesterol, and low triglycerides are not associated with decreased cardiovascular disease risk.

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: 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: A

Rationale: Correct answer: A - Hyperkalemia Rationale: 1. In CKD, impaired kidney function leads to decreased potassium excretion, causing hyperkalemia. 2. Hyperkalemia can result in life-threatening cardiac arrhythmias. 3. Monitoring potassium levels is crucial in CKD management. Summary: B: Hypoglycemia - Not typically associated with CKD, more common in diabetes. C: Hyperglycemia - Common in diabetes, but not a typical complication of CKD. D: Hypercalcemia - Uncommon in CKD, more often seen in hyperparathyroidism.

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: C

Rationale: The correct answer is C because stopping insulin when blood sugar is normal can lead to hyperglycemia. Choice A shows understanding of managing diabetes. Choice B indicates monitoring blood sugar, crucial for diabetes management. Choice D demonstrates adherence to medication schedule, essential for controlling blood sugar levels. Stopping insulin prematurely can disrupt the balance and result in complications.

Correct Answer: C

Rationale: The primary purpose of an abdominal binder after surgery is to increase circulation. An abdominal binder helps improve blood flow to the surgical site, which can aid in reducing swelling, promoting healing, and preventing complications such as blood clots. It provides gentle compression to support the abdominal muscles and tissues without restricting circulation. Choice A (Promote comfort) is incorrect because while an abdominal binder may provide some comfort by supporting the abdomen, its primary purpose is not solely for comfort. Choice B (Prevent infection) is incorrect because an abdominal binder does not directly prevent infection. Infection prevention is primarily achieved through proper wound care and infection control practices. Choice D (Provide wound care) is incorrect because an abdominal binder does not provide wound care. Wound care involves cleaning, dressing changes, and monitoring for signs of infection, which are separate from the purpose of an abdominal binder.
