A nurse on a medical-surgical unit knows that for clients with a BMI greater than or equal to 30, it is important to:

Choice A reason: Fluid volume deficit is a condition in which the body loses more fluid than it gains, resulting in dehydration, hypotension, and electrolyte imbalances. It is not a complication of IV fluid therapy, but rather a reason for initiating it.

Choice B reason: Fluid volume excess is a condition in which the body retains more fluid than it needs, resulting in edema, hypertension, and heart failure. It is a potential complication of IV fluid therapy, especially in older adults who have reduced renal function and cardiac output. The nurse's assessment findings of crackles, shortness of breath, and jugular vein distention are indicative of fluid overload and pulmonary congestion.

Choice C reason: Speed shock is a systemic reaction that occurs when a substance is administered too rapidly into the bloodstream, causing adverse effects such as chest pain, dyspnea, hypotension, and cardiac arrest. It is not a complication of IV fluid therapy, but rather a risk associated with IV medication administration.

Choice D reason: Pulmonary embolism is a blockage of one or more pulmonary arteries by a blood clot, fat, or air, causing impaired gas exchange, chest pain, dyspnea, and hemoptysis. It is not a complication of IV fluid therapy, but rather a possible outcome of venous thromboembolism, which can be prevented by using anticoagulants and mechanical devices.

Choice A reason: This is the correct answer because safety is the second level of Maslow's hierarchy of needs, and it includes the needs for security, stability, protection, and freedom from fear and anxiety. The couple who just lost their house in a fire are likely experiencing a threat to their safety needs, as they have lost their shelter, possessions, and sense of security. The nurse should identify and address their safety needs as a priority, and help them find alternative housing, financial assistance, and emotional support.

Choice B reason: This is not the correct answer because self-actualization is the highest level of Maslow's hierarchy of needs, and it includes the needs for personal growth, fulfillment, and realization of one's potential. The couple who just lost their house in a fire are unlikely to be concerned with their self-actualization needs at this time, as they have more pressing and basic needs to meet. The nurse should focus on their lower-level needs first, before helping them achieve their higher-level needs.

Choice C reason: This is not the correct answer because esteem is the fourth level of Maslow's hierarchy of needs, and it includes the needs for self-respect, confidence, recognition, and appreciation. The couple who just lost their house in a fire may experience a loss of esteem, as they may feel ashamed, helpless, or worthless. However, their esteem needs are not the most urgent or important at this time, as they have more fundamental needs to satisfy. The nurse should support their esteem needs by showing empathy, respect, and encouragement, but not neglect their lower-level needs.

Choice D reason: This is not the correct answer because love and belonging is the third level of Maslow's hierarchy of needs, and it includes the needs for affection, intimacy, friendship, and social acceptance. The couple who just lost their house in a fire may benefit from their love and belonging needs, as they may seek comfort, support, and connection from others. However, their love and belonging needs are not the primary or essential at this time, as they have more basic and vital needs to fulfill. The nurse should facilitate their love and belonging needs by providing a caring and compassionate environment, but not overlook their lower-level needs.
