A nursing instructor is conducting a class on the different types of blood cells.
Which of the following would the instructor include as the correct function?
Erythrocytes supply our cells with oxygen from the lungs to the tissues.
Erythrocytes control bleeding from microscopic to major tears in our tissues.
Leukocytes supply our cells with oxygen from the lungs to the tissues.
Thrombocytes control bleeding.
The Correct Answer is A
Choice A rationale:
Erythrocytes, also known as red blood cells, are responsible for supplying our cells with oxygen from the lungs to the tissues. Hemoglobin, a protein within erythrocytes, binds to oxygen in the lungs and releases it in the body's tissues, ensuring that our cells receive the oxygen they need for metabolic processes. This is the primary function of erythrocytes.
Choice B rationale:
Erythrocytes do not control bleeding from microscopic to major tears in our tissues. Hemostasis, or the control of bleeding, is primarily the role of platelets (thrombocytes) and clotting factors in the blood. While erythrocytes are essential for oxygen transport, they are not directly involved in the process of controlling bleeding.
Choice C rationale:
Leukocytes, also known as white blood cells, are not responsible for supplying our cells with oxygen. Their primary function is to help our body fight infection and respond to various immune challenges, including bacterial and viral infections.
Choice D rationale:
Thrombocytes, also known as platelets, play a crucial role in controlling bleeding. They are responsible for the initial stages of hemostasis, forming blood clots to prevent excessive bleeding when blood vessels are damaged. This is their primary function, distinct from the role of erythrocytes in oxygen transport. .

Correct Answer is A
Explanation
Choice A rationale:
Antiviral drugs are metabolized in the liver, and hepatic impairment can affect the metabolism and elimination of these drugs. Therefore, the nurse should administer antiviral therapy cautiously to clients with hepatic impairment to prevent potential drug toxicity. Hepatic impairment can alter the pharmacokinetics of antiviral drugs, leading to increased drug levels in the bloodstream.
Choice B rationale:
Renal impairment is not typically a contraindication for antiviral therapy. While some medications may require dose adjustments in patients with renal impairment, it is not a general concern for antiviral drugs. The primary organ responsible for the metabolism of antiviral drugs is the liver.
Choice C rationale:
Diabetes and hypertension are chronic medical conditions that are not directly related to the administration of antiviral therapy. These conditions do not significantly impact the pharmacokinetics or pharmacodynamics of antiviral drugs. Therefore, they are not primary factors to consider when administering antiviral therapy.
Choice D rationale:
Hypertension, like diabetes, is not directly related to the administration of antiviral therapy. Antiviral drugs primarily interact with the liver's metabolic pathways, and hypertension does not have a significant impact on drug metabolism.
Correct Answer is A
Explanation
Choice A rationale:
Emetics are medications that induce vomiting and are used in cases of drug overdose, ingestion of toxic substances, or other situations where rapid removal of the ingested substance is necessary. However, it is crucial that the client's mental status is intact and they can cooperate and understand the need to induce vomiting. If a client is unconscious or unable to protect their airway, inducing vomiting can lead to aspiration and further complications.
Choice B rationale:
Clients with existing severe hypertension should not be administered emetics, as the act of inducing vomiting can lead to a sudden increase in blood pressure, potentially causing adverse cardiovascular events.
Choice C rationale:
Clients with a medical history of convulsions (seizures) should not be given emetics. Inducing vomiting may lead to a convulsive episode, which can be harmful and increase the risk of aspiration.
Choice D rationale:
Clients with an existing condition of hemorrhagic diathesis (a tendency to bleed excessively) should not be administered emetics. Inducing vomiting can cause mucosal damage and bleeding in the gastrointestinal tract, further exacerbating the client's condition.
