Which IV solution would the nurse anticipate administering to a patient with fluid deficit who requires isotonic fluid replacement?
3% Saline
Saline 0.45%
Saline 0.9%
Dextrose 10%
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A: True
The statement that a patient with alkalosis can develop hyperkalemia is generally incorrect. Alkalosis, which is a condition characterized by a higher-than-normal pH in the blood, typically leads to hypokalemia rather than hyperkalemia. This occurs because alkalosis causes potassium to shift from the extracellular fluid into the cells, reducing the plasma potassium concentration. Therefore, it is uncommon for alkalosis to result in hyperkalemia.
Choice B: False
The correct answer is that a patient with alkalosis is unlikely to develop hyperkalemia. Alkalosis usually causes a decrease in plasma potassium levels, leading to hypokalemia. This is due to the movement of potassium ions into the cells in exchange for hydrogen ions, which are moved out of the cells to help buffer the increased pH. Consequently, the plasma potassium concentration drops, making hyperkalemia an unlikely outcome in the presence of alkalosis.
Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A: Collect patient information
This is the first step in the nursing process, known as the assessment phase. During this phase, the nurse gathers comprehensive information about the patient’s health status, including medical history, physical examination findings, and any relevant diagnostic test results. This information forms the foundation for identifying the patient’s health needs and planning appropriate care.
Choice B: Identify any clinical problems
The second step is the diagnosis phase, where the nurse analyzes the collected data to identify the patient’s health problems. These problems can be actual or potential issues that require nursing intervention. Accurate identification of clinical problems is crucial for developing an effective care plan.
Choice C: Decide a plan of action
The third step is the planning phase. In this phase, the nurse sets measurable and achievable goals for the patient’s care and decides on the appropriate nursing interventions to address the identified clinical problems. The plan of action should be individualized to meet the specific needs of the patient.
Choice D: Carry out the plan
The fourth step is the implementation phase, where the nurse executes the planned interventions. This may involve administering medications, providing education, performing procedures, or coordinating with other healthcare professionals. The goal is to achieve the desired patient outcomes as outlined in the care plan.
Choice E: Determine whether the plan was effective
The final step is the evaluation phase. In this phase, the nurse assesses the patient’s response to the implemented interventions and determines whether the goals of the care plan have been met. If the desired outcomes are not achieved, the nurse may need to revise the care plan and repeat the process.
