A client is receiving an intravenous (IV) solution over a short amount of time to replace volume losses. The nurse understands that this IV solution is most likely to be:

isotonic.

hypotonic.

hypertonic.

Hyperosmotic

Answer and Explanation

The Correct Answer is A

A. Isotonic solutions have a similar osmolarity to that of blood plasma, meaning they exert the same osmotic pressure as blood. This equilibrium prevents the movement of water across cell membranes, thereby maintaining cell volume and preventing cellular dehydration or swelling. Examples of isotonic solutions commonly used for intravenous fluid replacement include 0.9% saline (normal saline) and lactated Ringer's solution.
B. Hypotonic solutions have a lower osmolarity than blood plasma, meaning they exert less osmotic pressure than blood. When administered, hypotonic solutions cause water to move into cells, leading to cellular swelling. While hypotonic solutions can help hydrate cells and replenish intracellular fluid, they are not typically used for rapid volume replacement because they can exacerbate extracellular fluid deficits and cause complications such as cerebral edema or cardiovascular collapse.
C. Hypertonic solutions have a higher osmolarity than blood plasma, meaning they exert greater osmotic pressure than blood. When administered, hypertonic solutions cause water to move out of cells, leading to cellular shrinkage. Hypertonic solutions are often used to expand intravascular volume in cases of severe hypovolemia or shock, as they rapidly increase blood osmolarity and draw fluid from the interstitial space into the bloodstream. Examples of hypertonic solutions include 3% saline and 5% dextrose in 0.9% saline.
D. Hyperosmotic solutions have an elevated osmolarity compared to blood plasma, indicating a higher concentration of solutes. These solutions exert osmotic pressure that draws water out of cells, leading to cellular dehydration. While hyperosmotic solutions are not commonly used for rapid volume replacement due to their pot

Correct Answer is ["A","B","C","D","E"]

Explanation

A. The health status prior to the accident can influence how individuals respond to stress. Clients with pre-existing medical conditions, chronic pain, or disabilities may experience increased stress due to concerns about exacerbation of their conditions, recovery, or long-term consequences. Therefore, health status prior to the accident can impact the degree of stress experienced.
B. Age can influence individuals' coping mechanisms and resilience in response to stress. Younger individuals may have less life experience and coping skills, while older individuals may have accumulated more experience and developed better coping strategies over time. Additionally, age-related factors such as physical resilience and social support networks can affect how individuals respond to stressors. Therefore, different ages can influence the degree of stress experienced.
C. External resources such as social support networks, access to healthcare, financial stability, and community resources can significantly impact individuals' ability to cope with stress. Clients with strong support systems, adequate access to medical care, and financial security may experience lower levels of stress compared to those lacking these resources. Therefore, external resources can influence the degree of stress experienced.
D. Individual problem-solving skills play a crucial role in how individuals perceive and manage stressful situations. Clients with strong problem-solving skills may feel more confident in their ability to address challenges and may experience lower levels of stress. Conversely, clients with limited problem-solving skills may feel overwhelmed and experience higher levels of stress. Therefore, individual problem- solving skills can influence the degree of stress experienced.
E. Personality traits such as resilience, optimism, neuroticism, and coping styles can impact how individuals respond to stressors. For example, individuals with resilient personalities and positive coping styles may adapt more effectively to stressors and experience lower levels of stress. Conversely, individuals with neurotic personalities or maladaptive coping styles may be more prone to experiencing heightened stress levels. Therefore, personalities can influence the degree of stress experienced.

A. a butterfly needle B. a peripherally inserted central catheter C. a peripheral IV-lock D. a small gauge (16g) peripheral anglocath

Correct Answer is B

Explanation

B. A PICC line is a long, flexible catheter inserted into a peripheral vein, typically in the upper arm, and advanced until the tip lies in the superior vena cava or the cavoatrial junction. PICC lines are suitable for long-term venous access and are often used for administering medications, including antibiotics, over several weeks or months. They offer stable and reliable access, reducing the need for frequent venipunctures.

A. Butterfly needles are typically used for short-term venous access, such as for blood draws or administering medications that do not require long-term therapy. They are not suitable for prolonged use or for administering medications over several weeks, as they are not designed for secure and stable access over an extended period.
C. A peripheral IV-lock, also known as a saline lock or heplock, is a short catheter inserted into a peripheral vein and then capped off for intermittent use. While peripheral IV-locks are suitable for short-term venous access, they are not ideal for prolonged therapy lasting several weeks. Additionally, they may not provide the necessary stability and reliability for administering IV antibiotics over an extended period.
D. A small gauge peripheral angiocath refers to a short catheter inserted into a peripheral vein for intravenous access. While a larger gauge catheter, such as a 16-gauge, may allow for faster infusion rates and is suitable for certain situations requiring rapid fluid administration, it may not be the most appropriate choice for long-term IV antibiotic therapy. The choice of gauge depends on factors such as the client's vein size, the viscosity of the medication, and the duration of therapy.
