Standard precautions are established by the Center for Disease Control (CDC) How would a nurse explain when standard precautions are to be used with a client?

Standard precautions are to be used for any client, regardless of whether an infection has been identified.

Standard precautions are used when the client has an infection that is transmitted on air currents.

Standard precautions are to be used when the client has a pathogen that can spread via moist droplets.

Standard precautions are only used when there is an infection that is spread by indirect contact with an organism.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

Checking a restrained patient every 45 minutes might be too frequent and could interfere with the patient's rest and comfort, especially if the restraint is necessary for their safety. It could also lead to increased agitation and resistance from the patient, making it more challenging for the healthcare providers to manage the situation effectively.

Choice B rationale:

Checking on a restrained patient every 30 minutes is also too frequent for the reasons mentioned above. Patients need some time to rest and recover, and constant monitoring might be perceived as intrusive and threatening, potentially escalating the situation.

Choice C rationale:

Checking on a restrained patient every hour might not be sufficient, especially if the patient is at high risk of harming themselves or others. Waiting for an hour between checks could lead to dangerous situations, as a lot can happen in that time frame.

Choice D rationale:

Checking on a restrained patient every 2 hours strikes a balance between ensuring the patient's safety and respecting their privacy and comfort. It allows healthcare providers to monitor the patient's condition and intervene promptly if necessary while also giving the patient some space to rest and recover.

Correct Answer is A

Explanation

Choice A rationale:

Diastolic pressure represents the pressure in the arteries when the heart is at rest between contractions. It specifically measures the force of blood against the arterial walls when both the atria and ventricles are relaxed, allowing the heart to fill with blood. Diastolic pressure is the bottom number in a blood pressure reading (e.g., 120/80 mmHg), indicating the pressure in the arteries during the heart's resting phase. Elevated diastolic pressure is an important indicator of increased risk for cardiovascular diseases, such as hypertension.

Choice B rationale:

This statement describes systolic blood pressure, which measures the pressure in the arteries when the heart's ventricles contract and pump blood into the circulation. Systolic pressure is the top number in a blood pressure reading (e.g., 120/80 mmHg) and represents the highest pressure reached in the arteries during a cardiac cycle.

Choice C rationale:

This description is not accurate for either diastolic or systolic pressure. Both atria and ventricles do not contract simultaneously; they follow a specific sequence to ensure effective pumping of blood through the heart.

Choice D rationale:

This statement is incorrect as it does not align with the definitions of diastolic or systolic blood pressure. Diastolic pressure specifically measures the pressure in the arteries during the heart's resting phase, not when the ventricles relax. .

A. Drinking something cold. B. Exercising. C. An outdoor temperature of 99°F. D. A cold climate. E. Physical inactivity.

Correct Answer is ["A","B","E"]

Explanation

Choice A rationale:

Drinking something cold can lower the oral temperature temporarily. When a person consumes something cold, the blood vessels in the mouth can constrict, leading to a lower temperature reading. However, it's important to note that this effect is temporary.

Choice B rationale:

Exercising can increase blood circulation and raise body temperature. However, immediately after intense physical activity, the body might start sweating, leading to a temporary drop in temperature. Prolonged or moderate exercise, on the other hand, generally increases body temperature.

Choice C rationale:

An outdoor temperature of 99°F does not directly affect body temperature. Body temperature is regulated internally and does not fluctuate based on external temperatures unless the person is exposed to extreme conditions for a prolonged period.

Choice D rationale:

A cold climate might lower skin temperature, but it does not necessarily reduce the body's core temperature significantly. The body has mechanisms to conserve heat in colder environments.

Choice E rationale:

Physical inactivity can lower body temperature, especially in situations where the person is sedentary for an extended period. Reduced physical activity can slow down metabolic processes, leading to a lower body temperature.
