Comprehensive Nursing Review: Ethics, Med Rec, Labs, and Calculations

Nursing Practice and Ethics: Patient Autonomy and Conflict Resolution

• In situations where a terminally ill client and their family disagree on the aggressiveness of care, the nurse must prioritize the client's autonomy, provided the client is competent.
• Case Scenario: A client states, "I just want to be done with all of this and be comfortable," while the family insists on aggressive treatments.
• Determination of Decision-Maker: As long as the client is competent, they are the sole decision-maker. The right to make decisions only defaults to others if the client is deemed incompetent or unable to make their own choices.
• Appropriate Nursing Responses:     - Facilitating Communication: The nurse should encourage the client to talk to the healthcare provider about their specific wishes for care (e.g., "Let’s talk to the provider about what you want your care to be").     - Avoiding Intermediaries: The nurse is not required to act as a primary intermediary between the client and family; the focus is on supporting the client's direct communication with the medical team.
• Inappropriate Responses to Avoid:     - Placing "undue pressure" on the client to listen to their family simply because the family cares for them.     - Assuming an intermediary role by promising to inform the family of treatment cessation without facilitating doctor-patient dialogue.     - Pressuring the client to convince the family to change their minds.
• Legal Considerations: If a client becomes incapable of making decisions, the nurse and healthcare team then look to the Power of Attorney (POA) for healthcare to discuss further treatment paths.

Medication Reconciliation Procedures and Rationales

• Definition and Timing: Medication reconciliation (Med Rec) is a formal process performed to ensure medication accuracy during transitions of care. It is required during:     - Admission to a facility.     - Transfer to a different unit (though not for simple bed changes on the same unit).     - Discharge from the facility.
• Rationales for Repeating the Process: Clients or families may feel frustrated by answering the same questions repeatedly, but the nurse must explain its necessity based on the following:     - It helps to reduce potential errors in both treatment and charting.     - Having an additional set of eyes (the nurse's assessment in addition to the provider's) serves as a safety check.     - It ensures the record is comprehensive and up-to-date at every point of environmental change.
• Data Sources for Medication Reconciliation: A thorough Med Rec typically requires at least two sources to verify the patient's current regimen. Examples include:     - A physician's office record and the pharmacy record.     - A physical bag of pill bottles and the pharmacy record.     - A client’s personal typed list and pharmacy records.
• Access Limitations: The assertion that employees can only see their own charting is incorrect; the reconciliation is a collaborative record accessible to the care team to ensure safety.

Effective Psychosocial Communication Techniques

• General Principle: When addressing psychosocial concerns or "psychosocial integrity," the correct nursing response is rarely about immediately fixing the problem.
• Test-Taking Tip: Look for answers that explore the client's feelings or "ask the question back" to allow the client to express their emotions.
• Application (Diabetes Scenario): If a client is crying about the prospect of life-long insulin injections, the nurse should use open-ended exploration.     - Best Response: "What is it about giving yourself the insulin shots that bothers you?"     - Avoidance of Quick Fixes: Solutions like arranging home health or teaching a family member to give the shots are premature and ignore the client's immediate emotional distress.     - Avoidance of Fear Tactics: Explaining the risks of complications if they don't take the shots is non-therapeutic when the client is in an acute emotional state.

Nutritional Management for Hyperkalemia

• Hyperkalemia refers to an elevated level of potassium in the blood. Managing this through diet involves avoiding foods with high potassium content.
• High-Potassium Foods to Avoid:     - Potatoes: Noted as being "super high" in potassium.     - Avocados     - Bananas: (Though often the most cited example, they are sometimes lower in relative content than potatoes, but still categorized as high-potassium for these assessments).     - Oranges/Orange Juice
• Lower Potassium/Low Nutrient Alternatives:     - Lettuce: Described as primarily fiber and water with minimal nutrient impact.     - Apples: While healthy and containing fiber, they are relatively low in potassium compared to the items listed above.
• General Observation: Potassium-rich foods are often generally healthy foods, making the diet complex for patients to navigate without specific guidance.

Renal Function and Laboratory Analysis in Older Adults

• Serum Creatinine: Creatinine is a byproduct of the natural breakdown and turnover of muscle tissue. It enters the bloodstream and is filtered out by the kidneys.
• Reference Ranges:     - Normal Serum Creatinine: $0.6\,mg/dL$ to $1.2\,mg/dL$.     - Abnormal (Example Case): $2.3\,mg/dL$ indicates significantly impaired renal filtration power.
• Chronic Kidney Disease (CKD): Characteristic of kidneys losing their ability to filter blood and produce urine efficiently, leading to elevated serum creatinine levels.
• Aging and Lab Values:     - Test-Taking Tip: Do not assume a significantly abnormal lab value is a result of "normal aging."     - Specific Stability: Many lab values remain stable as people age, including White Blood Cell (WBC) count, Hemoglobin ($Hgb$), Sodium ($Na$), and Potassium ($K$).     - Creatinine Paradox in Aging: While kidney function naturally weakens with age, muscle mass also tends to decrease. Because there is less muscle to break down (producing less creatinine) and weaker kidneys to filter it, the serum creatinine level typically stays the same in a healthy aging adult. An elevated level in an older adult is still a sign of pathology, not normal aging.
• Nursing Interventions for Elevated Creatinine:     - Review Medications: The nurse must screen for nephrotoxic drugs.     - NSAIDs (Non-Steroidal Anti-Inflammatory Drugs): These (e.g., ibuprofen) are the most common nephrotoxic drugs used by clients at home.     - Antibiotics: May require "renal dosing" (lower doses) if the patient has renal dysfunction.
• Fluid Management: In CKD, increasing fluid intake is often contraindicated as it can lead to fluid retention, pulmonary edema, or peripheral edema in the feet.
• Urgency: While an elevated creatinine in the context of CKD is abnormal, it is often a chronic finding rather than an acute, life-threatening emergency like severely elevated potassium.

Dosage Calculations and Unit Conversions

• Prescription Details: Administer $0.45\%\,sodium\,chloride$, $750\,mL$ IV, to infuse over $2$ hours.
• Dimensional Analysis/Calculation:     - Goal: Determine $mL/hr$.     - Equation: $\frac{750\,mL}{2\,hr} = 375\,mL/hr$.
• Rounding Rule: Always round to the nearest whole number as specified. $375$ is already a whole number.
• Note on Extraneous Information: The concentration of the fluid ($0.45\%$) is irrelevant to the volume-per-hour calculation.
• Conversion Factors: Mastery of both metric and imperial units is essential for more complex calculations, though they were not required for this specific single-step problem.
