Correct Answer: B

Rationale: The correct answer is B because critical thinking helps nurses analyze complex situations, identify relevant information, and plan effective interventions. It allows for systematic problem-solving and decision-making, leading to optimal patient care outcomes. Choice A is incorrect as critical thinking doesn't guarantee immediate answers. Choice C is incorrect because critical thinking complements clinical guidelines rather than replacing them. Choice D is incorrect as physical assessments are essential in nursing care and critical thinking enhances, not bypasses, this process.

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: D

Rationale: A score of 6 on the MoCA tool indicates severe cognitive impairment because the MoCA is scored out of 30, with a lower score indicating more severe impairment. A score of 6 is significantly below the normal range, indicating severe cognitive deficits affecting various cognitive domains. This score would suggest significant impairment in memory, attention, language, visuospatial abilities, and executive functions. Therefore, Option D is correct. Options A, B, and C are incorrect as they suggest no, mild, or moderate impairment, which would not align with a score as low as 6 on the MoCA tool.

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: Eggs. Eggs are considered a complete protein because they contain all nine essential amino acids required by the body. These amino acids are necessary for various bodily functions, such as muscle growth and repair. Corn (A), peanuts (C), and sunflower seeds (D) are incomplete proteins as they lack one or more essential amino acids. Therefore, eggs are the best choice for a complete protein source compared to the other options provided.
