A nurse is reinforcing teaching about the side effects of metoprolol. Which of the following client statements indicates an understanding of the teaching?

Choice A reason: Gloves prevent MRSA spread via contact during oral care, a high-risk task. This adheres to contact precautions for infection control.

Choice B reason: Masks aren’t needed for MRSA patients; it’s not airborne. Contact precautions suffice, so this is unnecessary outside specific contexts.

Choice C reason: Negative pressure suits airborne pathogens, not MRSA, which spreads by contact. This overcomplicates room requirements for this infection.

Choice D reason: HEPA filters address air quality, irrelevant to MRSA’s contact transmission. Standard isolation, not filtration, controls this bacterial spread.

Choice A reason: Decreased blood pressure is not a direct sign of fluid overload; it may indicate hypovolemia or shock. Fluid overload increases intravascular volume, typically raising pressure initially. This finding contradicts the excess fluid state in enteral feeding complications, where the body retains too much water, affecting other systems first.

Choice B reason: Decreased skin turgor suggests dehydration, not fluid overload. In overload, excess fluid accumulates in tissues, potentially causing edema, not poor elasticity. Enteral feeding can lead to overhydration if mismanaged, making turgor an unreliable indicator here, as it reflects fluid deficit rather than the excess seen in this scenario.

Choice C reason: Weight loss occurs with fluid loss or malnutrition, not overload. Fluid overload from enteral feedings causes rapid weight gain due to water retention. This finding opposes the expected physiology of excess fluid, where the body holds onto water, increasing mass, not shedding it as in dehydration.

Choice D reason: Crackles in the lungs indicate fluid overload, as excess fluid from enteral feedings backs up into pulmonary circulation, causing pulmonary edema. This audible sign reflects fluid escaping into alveoli, impairing gas exchange, a common complication when intake exceeds the body’s ability to excrete water effectively.
