A nurse is admitting a client who has a wound infected with methicillin-resistant Staphylococcus aureus (MRSA). Which of the following types of precautions should the nurse plan to initiate?

Choice A rationale:

Cyanosis - Cyanosis is a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. This is an objective sign that can be visually assessed, not based on the patient's description.

Choice B rationale:

Petechiae - Petechiae are small, pinpoint, red or purple spots on the skin caused by bleeding under the skin. Like cyanosis, this is a physical finding that can be observed directly.

Choice C rationale:

Dizziness - This is the correct choice. Dizziness is a subjective sensation that the patient experiences. It cannot be directly observed and relies on the patient's description of feeling unsteady, lightheaded, or having a spinning sensation.

Choice D rationale:

Blood pressure - Blood pressure is an objective measurement that can be taken using a blood pressure cuff and a stethoscope or automated device. It is not based on the patient's description and does not fall under subjective data.

Choice A rationale:

Dyspnea (shortness of breath) is a common finding in clients with emphysema. Emphysema is a chronic obstructive pulmonary disease characterized by the destruction of lung tissue, leading to reduced lung elasticity and airflow limitation, which can result in difficulty breathing.

Choice B rationale:

Clubbing of the fingers is another expected finding in clients with advanced emphysema. Clubbing is the swelling and rounding of the fingertips, often associated with chronic respiratory conditions. It is thought to be a result of chronic hypoxia and inadequate oxygenation.

Choice C rationale:

Deep respirations are not typically associated with emphysema. Clients with emphysema often exhibit shallow, rapid respirations due to the loss of lung tissue elasticity, which impairs the normal respiratory mechanics.

Choice D rationale:

Bradycardia (slow heart rate) is not a common finding in emphysema. Emphysema primarily affects the respiratory system and does not directly influence heart rate. Bradycardia could be related to other factors but is not a characteristic finding of emphysema.

Choice E rationale:

Barrel chest is a classic physical finding in clients with emphysema. It results from the hyperinflation of the lungs due to the trapping of air in the damaged alveoli. This gives the chest a rounded appearance, similar to the shape of a barrel.
