After an initial skin assessment, the nurse documents the presence of a 2 centimeter area that is reddened and non-blanchable.
How will the nurse document the wound stage?
Stage 4.
Stage 2.
Stage 1.
Stage 3.
The Correct Answer is C
Choice A rationale
Stage 4 pressure injuries involve full-thickness skin and tissue loss with exposed or directly palpable fascia, muscle, tendon, ligament, cartilage, or bone in the ulcer. The presence of slough or eschar may be visible, and undermining or tunneling often occurs. Since this wound is described only as reddened and non-blanchable without any tissue loss or depth, it does not meet the severe physiological criteria required for a stage 4 classification.
Choice B rationale
Stage 2 pressure injuries are characterized by partial-thickness loss of skin with exposed dermis. The wound bed is viable, pink or red, and moist, and may also present as an intact or ruptured serum-filled blister. This stage does not include adipose or deeper tissues. Because the nurse documented non-blanchable redness rather than a break in the skin or a blister, the injury has not yet progressed to a stage 2 level.
Choice C rationale
Stage 1 pressure injuries consist of intact skin with a localized area of non-blanchable erythema. This means that when pressure is applied to the red area, it does not turn white, indicating that the microcirculation is compromised but the skin remains whole. This is the earliest clinical sign of pressure-related tissue damage. The description of a 2 centimeter reddened, non-blanchable area perfectly matches the diagnostic criteria for this stage of skin breakdown.
Choice D rationale
Stage 3 pressure injuries involve full-thickness loss of skin, in which adipose tissue is visible in the ulcer and granulation tissue and epibole are often present. Slough or eschar may be visible, but deeper structures like muscle or bone are not exposed. The assessment findings in this scenario do not mention any cavitation, loss of skin layers, or visible fat, which means the wound is significantly less advanced than a stage 3 injury.

Correct Answer is C
Explanation
Choice A rationale
Hypertonic refers to the osmolarity or solute concentration of a solution compared to another, typically across a semi-permeable membrane. It describes a state where the concentration of solutes is higher than that of the intracellular fluid, causing water to move out of cells. While acid-base imbalances can occur alongside osmotic shifts, hypertonic does not describe the pH level of the blood. Normal blood osmolarity ranges from 275 to 295 milliosmoles per kilogram of water.
Choice B rationale
Acidotic describes a state where the blood pH falls below the normal range of 7.35 to 7.45. This occurs when there is an accumulation of hydrogen ions or a loss of bicarbonate bases. If the hydrogen ion concentration increases, the pH value decreases. Since the question describes a loss of hydrogen ions or a gain of bases, the resulting state would be the opposite of acidosis. Acidosis can lead to central nervous system depression and cardiac arrhythmias.
Choice C rationale
Alkaline, or alkalotic, describes a blood pH that has increased above the normal range of 7.35 to 7.45. This condition results from a decrease in the concentration of hydrogen ions or an excess of basic substances like bicarbonate. In chemistry, a higher pH value indicates a more basic or alkaline solution. This shift affects protein binding and electrolyte balance, particularly calcium and potassium, often leading to increased neuromuscular excitability, muscle twitching, or tetany in the patient.
Choice D rationale
Neutral refers to a pH of 7.0, where the concentration of hydrogen ions and hydroxide ions is equal. In the human body, a pH of 7.0 is actually considered acidotic because it is lower than the physiological normal range of 7.35 to 7.45. Human life is only compatible with a very narrow pH range; therefore, a gain of bases will push the pH toward the alkaline side of the spectrum rather than settling at the neutral point.
Correct Answer is C
Explanation
Choice A rationale
During the full stage of illness, the patient experiences the specific signs and symptoms characteristic of influenza, such as high fever and body aches. While the viral load is high and the patient is certainly contagious, they are often less likely to spread the virus because they are feeling unwell and are typically isolated at home or in bed. The peak period of communicability often begins just before these systemic symptoms become fully manifested during the preceding stage.
Choice B rationale
The incubation period is the time interval between the initial entry of the influenza virus into the body and the first appearance of any symptoms. During this phase, the virus is replicating within the host's cells, but the viral load has generally not reached the threshold necessary for significant shedding and transmission to others. The host is asymptomatic and usually unaware they are infected. Consequently, they are not yet at the most infectious point of the disease cycle.
Choice C rationale
The prodromal stage is characterized by the onset of vague, non-specific symptoms like mild fatigue or a scratchy throat. This is the period when the student is most infectious because the viral shedding is at its peak, yet the student often continues their normal daily activities and social interactions. Because they do not yet feel sick enough to stay home, they unknowingly spread the virus to a large number of people through respiratory droplets and close contact.
Choice D rationale
The convalescent period is the recovery phase where the body's immune system has successfully brought the infection under control. Symptoms begin to disappear, and the person starts feeling better. During this time, the viral load decreases significantly as the virus is cleared from the respiratory tract. While some low-level shedding might still occur in certain individuals, the risk of transmitting the influenza virus to others is at its lowest compared to the earlier active stages.
