A nurse is preparing to administer furosemide 30 mg IV bolus stat. Available is furosemide injection 10 mg/mL. How many mL should the nurseadminister? (Round the answer to the nearest whole number. Use leading zero if it applies. Do not use a trailing zero.)

A) Increase in the startle reflex:
As people age, many of their physiological responses become less efficient, but some reflexes, such as the startle reflex, may actually become more pronounced or exaggerated. This occurs due to changes in the nervous system and decreased inhibition of certain reflex pathways. The startle reflex, which is an automatic response to sudden stimuli, can become more sensitive in older adults as a result of slower processing in the central nervous system.

B) Increase in muscle mass:
With aging, there is typically a decrease in muscle mass, a condition called sarcopenia, which leads to reduced strength and physical endurance. This loss of muscle mass starts around the age of 30 and accelerates after age 60. Therefore, muscle mass generally decreases rather than increases in older adults.

C) Decrease in body fat:
In older adults, body fat generally increases, particularly in the abdominal area, as muscle mass decreases and metabolism slows. While there may be some loss of subcutaneous fat in the face and extremities, visceral fat often increases, contributing to a higher body fat percentage.

D) Decrease in systolic blood pressure:
As people age, systolic blood pressure tends to increase, not decrease. This is due to the stiffening of the arteries and reduced elasticity of the vascular walls, which makes it harder for blood vessels to expand and contract with each heartbeat. This leads to a rise in systolic blood pressure while diastolic blood pressure may remain stable or decrease slightly.

A) Safety needs:
In Maslow's hierarchy of needs, safety needs are the second level, after physiological needs, and include the need for security and protection from harm. In this scenario, the client’s concern about where to hide their cellphone during the procedure reflects anxiety related to the potential loss or theft of personal property, which relates to safety and security. By offering to lock the cellphone in a secure area, the nurse is addressing the client's need for safety and reassurance about their belongings while undergoing a medical procedure.

B) Esteem needs:
Esteem needs are related to feelings of self-worth, accomplishment, and respect from others. While a person’s sense of esteem can be affected by how others treat their belongings, this particular situation does not relate to the client seeking recognition or respect. The client’s anxiety about where to place the cellphone is more about feeling secure and protected, rather than about esteem or recognition from others.

C) Love and belonging needs:
Love and belonging needs are associated with the need for interpersonal relationships, affection, and social connections. While the nurse’s interaction with the client may help foster a sense of comfort and connection, the concern about the cellphone does not stem from a need for social support or relationships. Instead, it is related to safety and security.

D) Physiological needs:
Physiological needs represent the most basic level of Maslow's hierarchy and include things like air, food, water, and shelter. Although the client is preparing for a medical procedure, their concern about the cellphone does not fall under this category. The focus here is on the safety of the client’s belongings, which is a higher-level need than basic physiological survival.
