Answer: d. Confounding

Explanation:

In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).

For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). Controlling for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.

Safe patient handling and mobility (SPHM) and preventing physical injury is a professional, legal, and ethical concern that applies to: patients, family members, and intra-professional health providers.

Safe patient handling and mobility (SPHM) is a professional, legal, and ethical concern that typically involves the use of assistive devices or equipment, so as to ensure a patient is safely mobilized and that health-care providers avoid high-risk manual patient handling tasks.

Some of the advantages of safe patient handling and mobility (SPHM) include:

Preventing physical injury to both the patient and care provider.

It improves the safety of a patient.

It enhances the quality of care received by a patient.

Going about her cleaning routine as usual, Jayla sprays an aerosol bleach cleanser in her bathroom and then leaves to let it air

SashulF [63]

Answer:

inhaled poison

Explanation:

Grimaldi was inside the bathroom when Jayla sprayed the aerosol bleach cleanser. The molecules of this cleanser spread quickly through the surroundings. Since the cat was inside the bathroom, it could have inhaled the bleach and the poison reached its lungs. This caused symptoms of wheezing, which is respiratory in nature, and shaking (seizures). Inhaling a poison leads to difficult in breathing among animals because it can cause the lungs to be inflamed.

The pressure gradient in the ventricles exceeds the pressure in the pulmonary artery and aorta.

Anna35 [415]

Answer:

TRUE

Explanation:

In the cardiovascular system, the blood flows from high pressure to low pressure.

In the ventricular ejection phase, when the muscles of the ventricles contract, the pressure gradient in ventricles rises. This increases in the pressure in the ventricles exceeds the pressure in the pulmonary artery and aorta, thus opening pulmonary and aortic valves and ejecting the blood from the heart.
