Correct Answer: B

Rationale: Step 1: Increasing potassium intake helps lower blood pressure by counteracting the effects of sodium. Step 2: Potassium helps relax blood vessel walls, reducing blood pressure. Step 3: Adequate potassium intake also helps the body balance fluids and maintain normal blood pressure. Summary: A - Increasing sodium intake is counterproductive for hypertension. C - Limiting caffeine helps, but not as directly as increasing potassium. D - Fruits and vegetables are important for a heart-healthy diet and should not be reduced.

Correct Answer: B

Rationale: The correct answer is B: Hamburgers. Clients with hypercholesterolemia should decrease their intake of saturated fats and cholesterol. Hamburgers are typically high in saturated fats and cholesterol due to the ground beef patty and cheese. Broiled catfish (A) is a lean protein source and can be a healthier option. Wheat bread (C) is a good source of fiber and can help lower cholesterol levels. Fresh apples (D) are a healthy choice low in saturated fats and cholesterol. Therefore, hamburgers should be decreased in the diet to manage hypercholesterolemia effectively.

Correct Answer: C

Rationale: The correct answer is C: Apply an airtight dressing. This is the first priority because it helps prevent air from entering the chest cavity, which can cause a tension pneumothorax. A tension pneumothorax can rapidly lead to respiratory distress and cardiac arrest. Applying an airtight dressing helps stabilize the condition until further medical intervention can be provided. Incorrect choices: A: Performing needle decompression is not the first priority as it is indicated for a tension pneumothorax once it has developed, not as a preventive measure. B: Applying a sterile dressing is important but not the first priority when dealing with a gunshot wound to the chest as sealing the wound to prevent air entry is more critical. D: Monitoring the client's ECG is not the first priority in this situation as addressing the potential tension pneumothorax takes precedence over monitoring the client's heart rhythm.

Correct Answer: B

Rationale: The correct answer is B: Alopecia. MOPP therapy for Hodgkin's disease commonly causes hair loss (alopecia), which directly affects body image. This is due to the impact on a person's physical appearance, leading to changes in self-perception and confidence. Cushingoid appearance (A) is a side effect of prolonged corticosteroid use, not typically associated with MOPP therapy. Temporary or permanent sterility (C) and pathologic fractures (D) are potential side effects of other cancer treatments but are not directly related to altering body image.

Correct Answer: B

Rationale: The correct answer is B: "Are you able to dress yourself?" This question is the most important because it directly assesses the patient's functional abilities post-stroke, providing crucial information about their independence and self-care abilities. It helps determine the patient's level of disability and need for assistance with activities of daily living. Choice A: "Do you wear glasses?" is not as important in this context as it does not directly address the patient's functional status post-stroke. Choice C: "Do you have any thyroid problems?" is irrelevant to the functional assessment of a patient post-stroke. Choice D: "How many times a day do you have a bowel movement?" is not as critical as assessing the patient's ability to perform basic activities of daily living.
