Comprehensive Assessment and Nursing Care for a Dehydrated Elderly Client

QUESTION

A 68 year old client presents to the emergency department with severe fatigue and a 4 day history of vomiting. The individual states he had very little to eat or drink during the last 4 days due to nausea. The client also reports he has not taken his prescribed medications due to the vomiting.

Admission vital signs:  Temperature 102.7 F, heart rate 116, respiratory rate 20 breaths / minute, blood pressure 86/54

Admission assessment findings:  Dry mucus membranes, tenting of the skin on the hands and arms, dark amber urine and the client reports having less urine than usual, nausea and vomiting, lethargy, muscle weakness.

Medical history: Hypertension, hyperlipidemia, history of heart failure, the client reports that a household family member had a confirmed case of influenza recently.

Laboratory values:  Sodium 150, potassium 5.5, chloride 110, BUN 42, creatinine 0.8, pH 7.32, PaC02 35, HC03- 20, Pa02 90, 02 saturation (pulse ox) on room air 98%

Physician (HCP) orders: Insert IV and infuse 0.45% normal saline at 100 ml/hour, monitor vital signs every 2 hours and administer routine medications when it is appropriate.  Medications: furosemide 40 mg by mouth daily in AM, metoprolol 25 mg by mouth 2 times a day.

Discussion Questions:

1. What type of fluid balance problem is the client exhibiting?
2. Discuss each of the electrolyte abnormalities present. What signs and symptoms would you expect for each one? How would each be treated? Provide rationale.
3. What is a collaborative plan of care for this client? What was the rationale for the IV fluids ordered? What would be the most appropriate course of action related to the client’s routine medications immediately following admission?
4. What are the nursing considerations related to the client’s medical history, history of present illness and the treatment plan?
5. What is your interpretation of this arterial blood gas sample? Discuss anticipated signs and symptoms for the ABG interpretation.
6. Explain the high potassium in this client.
7. SBAR note: Write an SBAR note from the perspective of the nurse calling the provider (HCP) related to the scenario following the client’s admission to the medical-surgical unit. SBAR note should have a situation,background,assessment,review response.

The response to this must be in paragraph form with rationale for
your decision making including professional references. This should be a
minimum of one hundred words and include at least 2 references. Your Med-Surg textbook
(Hinkle and Cheever) should be used as one of the references and cited in A-P-A format. At least 1 additional professional nursing reference (journal article or
professional web source) is required, other than your textbooks, to
support response to this discussion.

ANSWER

Comprehensive Assessment and Nursing Care for a Dehydrated Elderly Client

The presented scenario involves a 68-year-old client exhibiting signs of severe dehydration and electrolyte imbalances. This essay addresses the various aspects of the case, including the type of fluid balance problem, electrolyte abnormalities, collaborative care plan, nursing considerations, arterial blood gas (ABG) interpretation, high potassium levels, and a simulated SBAR note.

Fluid Balance Problem

The client is experiencing hypovolemic dehydration, indicated by the low blood pressure, increased heart rate, dry mucus membranes, tenting skin, and decreased urine output. This condition results from significant fluid loss, often due to vomiting and inadequate fluid intake.

Electrolyte Abnormalities

Sodium (Na+): Elevated sodium levels (hypernatremia) of 150 suggest water deficit, causing thirst, dry mucous membranes, and lethargy. Treatment involves administering isotonic fluids to correct dehydration.

Potassium (K+): Elevated potassium levels (hyperkalemia) at 5.5 can lead to muscle weakness and dysrhythmias. Treatment includes monitoring EKG, restricting potassium-rich foods, and possibly administering medications like kayexalate or loop diuretics to enhance potassium excretion.

Chloride (Cl-): Elevated chloride levels (hyperchloremia) at 110 are typically associated with dehydration and metabolic acidosis. Treatment involves addressing the underlying cause and restoring fluid balance.

Collaborative Care Plan

The collaborative plan includes inserting an IV for fluid replacement with 0.45% normal saline to correct dehydration and electrolyte imbalances. Vital signs monitoring every 2 hours aids in assessing response. The rationale for using normal saline is to restore extracellular fluid volume, while the ordered IV rate ensures gradual correction to prevent fluid overload. Medications should be administered when the client’s condition stabilizes.

Nursing Considerations

Given the client’s history of heart failure, careful fluid management is crucial to avoid exacerbating cardiac workload. The history of influenza exposure warrants considering the possibility of viral gastroenteritis. The client’s lethargy and dry mucous membranes point to dehydration severity. Monitoring vital signs and urine output, assessing for fluid overload signs, and closely watching potassium levels are essential.

ABG Interpretation

The ABG indicates metabolic acidosis (low pH) and compensatory respiratory response (low PaCO2). This could result from dehydration-induced lactic acid accumulation. Expected signs include rapid breathing and altered mental status.

High Potassium Interpretation

Hyperkalemia can result from dehydration, as reduced fluid volume causes potassium concentration to rise. Clinical manifestations may include muscle weakness, cardiac arrhythmias, and dyspnea.

SBAR Note

Situation: I am calling about our newly admitted 68-year-old client with severe dehydration and electrolyte imbalances.
Background: The client has a history of hypertension, hyperlipidemia, and heart failure. Recent vomiting and poor intake have led to hypovolemic dehydration and elevated electrolyte levels.
Assessment: Vital signs indicate low blood pressure, tachycardia, and decreased urine output. Electrolyte panel shows high sodium, potassium, and chloride levels.
Review Response: The provider ordered an IV of 0.45% normal saline for gradual rehydration. Electrolytes and vitals will be monitored closely.

Conclusion: Providing Comprehensive Care

This case highlights the critical role of nurses in assessing, managing, and collaborating in the care of dehydrated patients. A holistic approach integrating evidence-based interventions, monitoring, and proactive communication ensures effective treatment and optimal patient outcomes.
