What is an infectious disease that can be transmitted directly from one person to another?
A susceptible host
A communicable disease
A portal of entry to a host
A portal of exit from the reservoir
The Correct Answer is B
Choice A reason: A susceptible host is not an infectious disease, but a factor that influences the transmission of an infectious disease. A susceptible host is a person who is vulnerable to infection due to factors such as age, health status, immunization, or genetic predisposition. A susceptible host may become infected by a communicable disease, but it is not the disease itself.
Choice B reason: A communicable disease is an infectious disease that can be transmitted directly from one person to another. A communicable disease is caused by a pathogen, such as a virus, bacterium, fungus, or parasite, that can spread through contact, droplet, airborne, vector, or vehicle transmission. Examples of communicable diseases are influenza, tuberculosis, measles, malaria, and HIV/AIDS.
Choice C reason: A portal of entry to a host is not an infectious disease, but a factor that influences the transmission of an infectious disease. A portal of entry to a host is a route through which a pathogen can enter the body of a susceptible host and cause infection. A portal of entry to a host may be a break in the skin, a mucous membrane, or a body opening, such as the mouth, nose, eyes, or genitals. A portal of entry to a host may facilitate the transmission of a communicable disease, but it is not the disease itself.
Choice D reason: A portal of exit from the reservoir is not an infectious disease, but a factor that influences the transmission of an infectious disease. A portal of exit from the reservoir is a route through which a pathogen can leave the body of an infected person or animal and reach another susceptible host. A portal of exit from the reservoir may be a body fluid, such as blood, saliva, urine, or feces, or a body part, such as the skin, hair, or nails. A portal of exit from the reservoir may enable the transmission of a communicable disease, but it is not the disease itself.

Correct Answer is C
Explanation
Choice A reason: This is not the highest priority client because a urinary tract infection (UTI) is a common and treatable condition that affects the lower urinary system, such as the bladder or urethra. A fever of 38.5°C and flank pain can indicate that the infection has spread to the upper urinary system, such as the kidneys, which can cause pyelonephritis. Pyelonephritis is a serious but not lifethreatening complication that requires antibiotic therapy and hydration. The nurse should monitor the client's vital signs, urine output, and pain level and administer the prescribed medication and fluids.
Choice B reason: This is not the highest priority client because a deep vein thrombosis (DVT) is a blood clot that forms in a deep vein, usually in the lower extremities. A positive Homans' sign and edema in the affected leg can indicate that the clot is causing inflammation and obstruction of the blood flow. DVT is a serious but not lifethreatening complication that requires anticoagulant therapy and compression therapy. The nurse should monitor the client's vital signs, leg circumference, and pain level and administer the prescribed medication and stockings.
Choice C reason: This is the highest priority client because a myocardial infarction (MI) is a heart attack that occurs when the blood flow to a part of the heart muscle is blocked, causing tissue damage or death. Chest pain and shortness of breath can indicate that the client is experiencing acute cardiac ischemia, which can lead to cardiac arrest or heart failure. MI is a lifethreatening emergency that requires immediate intervention and treatment. The nurse should activate the rapid response team, monitor the client's vital signs, electrocardiogram, and oxygen saturation, and administer the prescribed medication and oxygen.
Choice D reason: This is not the highest priority client because a stroke is a brain attack that occurs when the blood flow to a part of the brain is interrupted, causing tissue damage or death. Slurred speech and facial droop can indicate that the client is experiencing acute neurological impairment, which can affect their communication and facial expression. Stroke is a serious but not lifethreatening complication that requires prompt evaluation and treatment. The nurse should monitor the client's vital signs, neurological status, and glucose level and administer the prescribed medication and fluids.
Correct Answer is C
Explanation
Choice A reason: Culturing the wound is not the nurse's priority assessment for this client, because it is not the most urgent and relevant action. Culturing the wound is a procedure that involves collecting a sample of the wound drainage and sending it to the laboratory for analysis, which can help identify the type and source of infection. Culturing the wound is an important intervention, but it should be done after inspecting the wound and assessing the drainage, and with a medical order and a sterile technique.
Choice B reason: Applying topical ointment to the wound is not the nurse's priority assessment for this client, because it is not the most urgent and relevant action. Applying topical ointment to the wound is a procedure that involves applying a medication or a dressing to the wound site, which can help prevent or treat infection, inflammation, or pain. Applying topical ointment to the wound is an important intervention, but it should be done after inspecting the wound and assessing the drainage, and with a medical order and a clean technique.
Choice C reason: Inspecting the wound and assessing the drainage is the nurse's priority assessment for this client, because it is the most urgent and relevant action. Inspecting the wound and assessing the drainage is a process that involves observing and measuring the wound site and the wound exudate, which can reveal the presence and severity of infection, injury, or healing. Inspecting the wound and assessing the drainage is an essential assessment, as it can guide the diagnosis, treatment, and evaluation of the client's condition.
Choice D reason: Calling the provider to initiate antibiotics is not the nurse's priority assessment for this client, because it is not the most urgent and relevant action. Calling the provider to initiate antibiotics is a communication that involves reporting the client's situation and requesting a prescription for an antimicrobial agent, which can help fight or prevent infection. Calling the provider to initiate antibiotics is an important communication, but it should be done after inspecting the wound and assessing the drainage, and with the necessary data and documentation.
