All patient teaching occurs in a formalized teaching session.

Choice A: True

The statement that all patient teaching occurs in a formalized teaching session is not accurate. While formalized teaching sessions are an important aspect of patient education, they are not the only method used. Formal sessions are structured and planned, often involving detailed explanations, demonstrations, and the use of educational materials. These sessions are beneficial for covering complex topics and ensuring that patients and caregivers have a thorough understanding of their health conditions and treatment plans.

Choice B: False

Patient teaching can occur in various settings and formats, not just in formalized teaching sessions. Informal teaching moments are equally important and often occur during routine interactions between healthcare providers and patients. These moments can include brief explanations, answering questions, and providing reassurance during procedures or daily care activities. Informal teaching is flexible and can be tailored to the patient’s immediate needs and readiness to learn, making it a crucial component of effective patient education.

Choice A: 3% Saline
3% Saline is a hypertonic solution, meaning it has a higher concentration of solutes compared to the blood plasma. It is typically used in critical care settings for specific conditions such as severe hyponatremia or cerebral edema. Administering 3% Saline to a patient with a fluid deficit who requires isotonic fluid replacement would not be appropriate because it could lead to cellular dehydration and other complications due to its high osmolarity.
Choice B: Saline 0.45%
Saline 0.45%, also known as half-normal saline, is a hypotonic solution. It has a lower concentration of solutes compared to blood plasma and is used to treat patients with hypernatremia or those who need to be rehydrated without adding too much sodium. However, it is not suitable for isotonic fluid replacement because it can cause cells to swell and potentially burst due to the influx of water into the cells.
Choice C: Saline 0.9%
Saline 0.9%, also known as normal saline, is an isotonic solution. It has the same concentration of solutes as blood plasma, making it ideal for fluid replacement in patients with a fluid deficit. Normal saline is commonly used to expand the extracellular fluid volume without causing significant shifts in fluid between compartments. This makes it the appropriate choice for isotonic fluid replacement.
Choice D: Dextrose 10%
Dextrose 10% is a hypertonic solution used primarily for providing calories in patients who need parenteral nutrition or for treating severe hypoglycemia. It is not suitable for isotonic fluid replacement because its high glucose content can lead to osmotic diuresis and fluid shifts that are not desirable in patients needing isotonic fluids.
