Which of the following substances is most likely to cause skin irritation in an individual with irritant-type contact dermatitis?
Harsh soaps.
Non-latex gloves.
Warm water.
Vegetable oils.
The Correct Answer is A
Choice A rationale
Harsh soaps are alkaline substances that disrupt the skin's natural acidic mantle and lipid barrier. This breakdown of the stratum corneum allows irritants to penetrate more easily, leading to a direct inflammatory response in the keratinocytes and resulting in the characteristic rash and inflammation of irritant contact dermatitis.
Choice B rationale
Non-latex gloves are designed to be hypoallergenic and are typically used to prevent allergic reactions, a different type of contact dermatitis. They are generally considered less irritating than latex gloves for individuals with latex allergies and are unlikely to be a primary cause of irritant contact dermatitis.
Choice C rationale
Warm water is generally not considered an irritant. While prolonged exposure to hot water can strip the skin of its natural oils, warm water used for a short duration is not a typical cause of irritant contact dermatitis unless the individual has a pre-existing skin barrier dysfunction.
Choice D rationale
Vegetable oils are generally considered emollients, meaning they help to moisturize and protect the skin barrier. They are typically used in skincare products for their soothing properties and are very unlikely to cause irritant contact dermatitis unless the individual has a specific allergy to a component. *.

Correct Answer is C
Explanation
Choice A rationale
Pneumonia is an infection of the lung parenchyma that causes inflammation and fluid to fill the alveoli. While this can impair gas exchange and cause respiratory distress, it is not the same as pulmonary edema, which is specifically the extravasation of fluid from the pulmonary capillaries into the interstitial space and alveoli, usually due to increased hydrostatic pressure.
Choice B rationale
Orthostatic hypotension is a drop in blood pressure upon standing, caused by autonomic dysfunction. This condition involves issues with blood pressure regulation, not a primary pathology of fluid accumulation in the lungs. In fact, these patients are often volume-depleted, which would make pulmonary edema less likely.
Choice C rationale
Congestive heart failure (CHF) is the most significant risk factor for pulmonary edema. In this condition, the heart's inability to pump effectively leads to a backup of blood in the pulmonary circulation. This increased pressure, known as increased hydrostatic pressure, forces fluid out of the capillaries and into the lung tissues, causing pulmonary edema.
Choice D rationale
Right ventricular hypertrophy is an enlargement of the right ventricle, often due to pulmonary hypertension. While this can eventually lead to right-sided heart failure and systemic edema, it does not typically cause pulmonary edema directly. Pulmonary edema is more commonly associated with left ventricular failure.
Correct Answer is ["1.5"]
Explanation
The patient has an order for Coumadin 3.75 mg today. The pill from the pharmacy is 2.5 mg. How many pills would you give?.
Step 1: Calculate the number of pills needed. 3.75 mg ÷ 2.5 mg = 1.5 pills. The nurse would give 1.5 pills.
