Answer and Explanation

The Correct Answer is ["A","B","C","D","F"]

Mild subcostal retractions: Subcostal retractions indicate that the muscles between the ribs are pulling inward during breathing. This is a sign of increased work of breathing and can indicate respiratory distress.

Wheezes noted throughout the lung fields: Wheezing is a high-pitched whistling sound produced during breathing, typically due to narrowed airways. It indicates airway obstruction, common in asthma exacerbations.

Client is pale: Pallor (pale skin) can indicate reduced oxygenation or perfusion to the tissues, which can occur during respiratory distress.

Heart rate of 122 beats/minute: Tachycardia (elevated heart rate) is a compensatory mechanism in response to decreased oxygen levels or increased respiratory effort.

Oxygen saturation 91% on room air: Oxygen saturation below 94% indicates hypoxemia (low blood oxygen levels), which is a critical finding requiring prompt intervention.

Correct Answer is D

Explanation

Rationale

A. The complement system is part of the immune response and can be activated in various conditions, including sepsis. However, activation of complement pathways does not directly cause DIC. Instead, in septic shock, the release of pro-inflammatory cytokines and tissue factor can trigger systemic coagulation activation, leading to DIC.

B. Inhibition of red blood cell production, such as in conditions like aplastic anemia or certain types of bone marrow disorders, does not directly cause DIC. DIC is primarily a disorder of excessive activation of clotting factors in response to underlying conditions like sepsis, trauma, or cancer.

C. Production of extra platelets, or thrombocytosis, is not the cause of DIC. Thrombocytosis can occur in response to various conditions, but DIC involves consumption of platelets due to widespread activation of clotting within the vasculature.

D. DIC is characterized by the widespread consumption and depletion of clotting factors and platelets as they are used up in the formation of microthrombi throughout the bloodstream. This depletion leads to an increased risk of bleeding due to insufficient clotting factors remaining to maintain hemostasis.

Correct Answer is ["12.5"]

Explanation

To calculate the dosage of amoxicillin suspension to be administered every 8 hours, one must first determine the total daily dosage in milligrams. Since 1 gram equals 1000 milligrams, 1.5 grams is equivalent to 1500 milligrams. This total daily dosage needs to be divided into three doses, as it will be administered every 8 hours.

Therefore, each dose will be 1500 mg divided by 3, which equals 500 mg per dose. The medication bottle states that there are 200 mg of amoxicillin in every 5 mL of suspension. To find out how many mL correspond to a 500 mg dose, set up a proportion: 200 mg/5 mL = 500 mg/x mL. Solving for x gives x = (500 mg * 5 mL) / 200 mg, which equals 12.5 mL

Therefore, the nurse should administer 12.5 mL of the amoxicillin suspension every 8 hours.
