A patient asks the nurse to define hypersensitivity reaction. The nurse begins by telling the patient that a hypersensitivity reaction is also called:

A. She only has one functioning kidney:

This choice is the most significant consideration when prescribing vancomycin to Mrs. Oza. Vancomycin is primarily eliminated from the body through the kidneys. Individuals with reduced kidney function, such as Mrs. Oza with only one functioning kidney, have a higher risk of vancomycin-associated nephrotoxicity (kidney damage). Therefore, her renal status is crucial information for determining the appropriate dosage of vancomycin and monitoring for any signs of kidney impairment during treatment.

B. She remains outdoors for long periods of time:

While spending time outdoors for long periods may have implications for Mrs. Oza's overall health, it is not directly relevant to the prescription of vancomycin. This information may be important for considering sun exposure, hydration, and other factors related to her arthritis and general well-being, but it does not specifically impact the pharmacokinetics or pharmacodynamics of vancomycin.

C. She has hypertension:

Mrs. Oza's hypertension is a relevant medical condition to consider in her overall health management. However, hypertension alone does not directly affect the prescription of vancomycin. Hypertension may influence the choice of antihypertensive medications or other aspects of her medical care, but it does not have a direct impact on the renal clearance or potential nephrotoxicity of vancomycin.

D. She enjoys an alcoholic beverage twice a week:

While alcohol consumption can interact with certain medications and impact overall health, it is not the most significant consideration when prescribing vancomycin to Mrs. Oza. Moderate alcohol consumption is unlikely to directly affect the pharmacokinetics or pharmacodynamics of vancomycin. However, excessive alcohol intake may contribute to liver dysfunction, which could indirectly influence drug metabolism. Nonetheless, in Mrs. Oza's case, her reduced renal function is a more critical factor to consider when prescribing vancomycin.

A. BP 98/62:

A blood pressure of 98/62 mmHg is within the normal range for an adult, although it's slightly lower than the average blood pressure. While monitoring blood pressure is important, this reading doesn't indicate a critical condition and doesn't require immediate intervention.

B. Urticaria:

Urticaria, also known as hives, is a skin rash characterized by raised, itchy welts. While it can be uncomfortable and may indicate an allergic reaction, it's not immediately life-threatening. However, it does warrant attention and further assessment.

C. Wheezing:

Wheezing is a high-pitched whistling sound that occurs during breathing and can indicate airway obstruction, such as in an allergic reaction or asthma exacerbation. Wheezing can be a sign of a severe allergic reaction or anaphylaxis, which requires immediate intervention to ensure the patient's airway remains open and to administer appropriate treatment.

D. Pulse rate 104/min:

A pulse rate of 104 beats per minute (bpm) is slightly elevated but within the normal range for an adult. While it's important to monitor heart rate, this finding alone doesn't indicate an immediate threat to the patient's life.
