A nurse is teaching a client about the use of ice for treatment of a soft-tissue injury. Which of the following instructions should be included? (Select All that Apply.)
Alternate the use of ice and heat.
Apply ice pack intermittently.
Do not place ice pack directly on the skin.
Leave ice pack on for no more than 20 minutes at a time.
The Correct Answer is B
Choice A Reason: Alternate the use of ice and heat
Alternating the use of ice and heat is not typically recommended for the initial treatment of a soft-tissue injury. Ice is generally used during the first 24-48 hours to reduce swelling and inflammation. Heat can be applied later to help relax muscles and improve blood flow, but it should not be used immediately after an injury as it can increase swelling.
Choice B Reason: Apply ice pack intermittently
Applying the ice pack intermittently is important to prevent skin damage and frostbite. It is generally recommended to apply ice for 15-20 minutes at a time, followed by a break of at least 20 minutes before reapplying. This helps to reduce swelling and pain without causing harm to the skin and underlying tissues.
Choice C Reason: Do not place ice pack directly on the skin
Placing an ice pack directly on the skin can cause frostbite and damage to the skin and tissues. It is important to wrap the ice pack in a thin cloth or towel before applying it to the injured area. This provides a barrier that protects the skin while still allowing the cold to penetrate and reduce swelling.
Choice D Reason: Leave ice pack on for no more than 20 minutes at a time
Leaving the ice pack on for no more than 20 minutes at a time is crucial to prevent frostbite and skin damage. Prolonged exposure to cold can cause harm, so it is important to limit the duration of each application and take breaks in between.

Correct Answer is C
Explanation
Choice A Reason: Cerebral edema is caused by cerebrospinal fluid flowing from the intraventricular space to the interstitial area of the brain
This statement is not accurate. Cerebral edema in meningitis is not primarily caused by the flow of cerebrospinal fluid (CSF) from the intraventricular space to the interstitial area. Instead, it is more related to the inflammatory response triggered by the infection.
Choice B Reason: Cerebral edema is caused by osmotic cerebral edema
Osmotic cerebral edema occurs when there is an imbalance in the osmotic pressure, leading to fluid accumulation in the brain. However, this is not the primary mechanism in meningitis. The edema in meningitis is more related to the inflammatory response and the by-products of the pathogen.
Choice C Reason: Cerebral edema is caused by the by-products of the pathogen that causes the meningitis
This statement is the most accurate. In meningitis, the infection triggers an inflammatory response, leading to the release of various by-products such as cytokines and other inflammatory mediators. These substances increase the permeability of the blood-brain barrier, resulting in fluid leakage and cerebral edema.
Choice D Reason: Cerebral edema is caused by whole body inflammation which affects the brain the most
While systemic inflammation can contribute to cerebral edema, the primary cause in meningitis is the localized inflammatory response in the brain and meninges. The by-products of the pathogen and the resulting inflammation are the main factors leading to cerebral edema.
Correct Answer is A
Explanation
Choice A Reason: Portal of entry
The client’s mouth serves as the portal of entry in the chain of infection. The portal of entry is the route through which an infectious agent enters the host. In the case of hepatitis A, the virus enters the body through the mouth when contaminated food or water is ingested. This link is crucial in the chain of infection as it determines how the pathogen gains access to the host’s body.
Choice B Reason: Susceptible host
A susceptible host is an individual who is at risk of infection due to factors such as a weakened immune system, age, or underlying health conditions. While the client in this scenario may be a susceptible host, the mouth specifically represents the portal of entry, not the host itself.
Choice C Reason: Infectious agent
The infectious agent is the pathogen that causes the disease. In this case, the infectious agent is the hepatitis A virus. The mouth is not the infectious agent but rather the entry point for the virus into the body.
Choice D Reason: Reservoir
A reservoir is the habitat in which the infectious agent normally lives, grows, and multiplies. Common reservoirs include humans, animals, and the environment. The client’s mouth is not a reservoir but the portal of entry for the hepatitis A virus.
