Question

A nurse is caring for a patient with dilutional hyponatremia (sodium: 130 mEq/L). Which order should the nurse question?

Answer 1

Correct Answers:

Encourage the patient to Increase oral fluid intake.

Rationale :

💧Dilutional hyponatremia occurs when excessive body water dilutes the serum sodium concentration.

🚫Increasing oral fluids would worsen the water excess and further decrease the sodium level.

🥤Management commonly includes fluid restriction, daily weights, and strict intake and output monitoring.

💊A loop diuretic such as furosemide may help remove excess water, while hypertonic saline is reserved for appropriately selected symptomatic cases.

📌Core Message:

Clients with dilutional hyponatremia generally require fluid restriction because increasing oral fluids can worsen sodium dilution.

Answer 2

Correct Answers:

Generalized muscle weakness
Blood Pressure: 158/94 mm/Hg
Positive Chvostek's sign
Positive Trousseau's sign
Heart rate: 118 beats/minute

Rationale :

🧪A calcium level of 7.2 mg/dL indicates hypocalcemia, while magnesium of 1.1 mg/dL indicates hypomagnesemia.

⚡Both electrolyte deficiencies increase neuromuscular excitability, producing weakness, tremors, cramps, and tetany.

🙂A positive Chvostek’s sign and positive Trousseau’s sign are classic manifestations of hypocalcemia.

❤️Hypomagnesemia can stimulate the cardiovascular system, causing hypertension, tachycardia, and dysrhythmias.

📌Core Message:

Hypocalcemia and hypomagnesemia produce increased neuromuscular excitability, positive Chvostek’s and Trousseau’s signs, weakness, tachycardia, and hypertension.

Answer 3

Correct Answers:

Respiratory alkalosis

Rationale :

🧪The pH of 7.48 indicates alkalemia because it is above the normal range of 7.35 to 7.45.

🫁The PaCO₂ of 30 mm Hg is low, identifying a respiratory cause of the alkalemia.

⚖️The bicarbonate level of 24 mEq/L remains normal, indicating no metabolic compensation.

📋These findings represent uncompensated respiratory alkalosis.

📌Core Message:

A high pH, low PaCO₂, and normal bicarbonate indicate uncompensated respiratory alkalosis.

Answer 4

Correct Answers:

Obtain pulse oximetry reading.
Elevate the head of the bed.
Stop IV infusion.

Rationale :

🚨Difficulty breathing during a rapid isotonic infusion suggests fluid volume overload and possible pulmonary edema.

⛔The nurse should immediately stop the infusion to prevent additional circulatory overload.

🛏️Elevating the head of the bed promotes lung expansion and decreases venous return to the heart.

🩸Pulse oximetry assesses the severity of impaired oxygenation and guides further intervention.

📌Core Message:

Suspected infusion-related fluid overload requires stopping the infusion, positioning the client upright, and immediately assessing oxygenation.

Answer 5

Correct Answers:

Administer 0.45% normal saline as prescribed
Restrict sodium intake
Monitor for agitation and confusion
Implement seizure precautions

Rationale :

🧂A sodium level of 158 mEq/L indicates significant hypernatremia, which causes water to move out of body cells.

💧Prescribed 0.45% sodium chloride gradually supplies hypotonic fluid to lower sodium and restore intracellular hydration.

🩺Hypertension and pitting edema indicate fluid volume excess, making sodium restriction appropriate.

🧠Hypernatremia can cause agitation, confusion, muscle twitching, and seizures, requiring neurological monitoring and seizure precautions.

📌Core Message:

Hypervolemic hypernatremia requires gradual hypotonic fluid replacement, sodium restriction, and close monitoring for serious neurological complications.

Answer 6

Correct Answers:

Metabolic acidosis – partially compensated

Rationale :

🧪The pH of 7.31 indicates acidemia.

⬇️The bicarbonate level of 18 mEq/L is decreased, identifying metabolic acidosis as the primary disorder.

🫁The PaCO₂ of 30 mm Hg is decreased because the lungs are eliminating additional carbon dioxide through respiratory compensation.

⚖️Because the pH remains outside the normal range, the disorder is partially compensated rather than fully compensated.

📌Core Message:

A low pH and bicarbonate with compensatory reduction in PaCO₂ indicate partially compensated metabolic acidosis.

Answer 7

Correct Answers:

Place the client on telemetry.

Rationale :

❤️A potassium level of 5.6 mEq/L indicates hyperkalemia, which can disrupt cardiac electrical conduction.

⚡Tingling suggests the electrolyte imbalance is producing neuromuscular manifestations.

📈Continuous telemetry allows immediate detection of peaked T waves, conduction delays, and lethal dysrhythmias.

🚨Cardiac monitoring takes priority because hyperkalemia can rapidly progress to ventricular dysrhythmias or cardiac arrest.

📌Core Message:

Symptomatic hyperkalemia requires immediate telemetry because dangerous cardiac conduction changes can occur rapidly.

Answer 8

Correct Answers

DKA, renal failure, and Kussmaul respirations [ Metabolic acidosis ]
Panic attack with rapid respirations [ Respiratory alkalosis ]
Persistent vomiting with NG suction [ Metabolic acidosis ]
COPD exacerbation with wheezing [ Respiratory alkalosis ]

Rationale :

🧪DKA and renal failure cause accumulation of acids or impaired acid excretion, producing metabolic acidosis.

😰Rapid breathing during a panic attack eliminates excessive carbon dioxide, producing respiratory alkalosis.

🤮Persistent vomiting and NG suction remove gastric hydrochloric acid, producing metabolic alkalosis.

🫁A COPD exacerbation causes carbon dioxide retention from impaired ventilation, producing respiratory acidosis.

📌Core Message:

Acid accumulation causes metabolic acidosis, hyperventilation causes respiratory alkalosis, gastric acid loss causes metabolic alkalosis, and carbon dioxide retention causes respiratory acidosis.

Answer 9

Correct Answers:

Tachycardia
Decreased blood pressure
Weak, thready pulse
Dry mucous membranes

Rationale :

💧Prolonged vomiting and diarrhea cause significant fluid volume deficit through gastrointestinal losses.

❤️Tachycardia develops as a compensatory response to maintain cardiac output despite reduced circulating volume.

🩺Decreased blood pressure and a weak, thready pulse indicate diminished intravascular volume and peripheral perfusion.

👄Dry mucous membranes are a common physical manifestation of dehydration.

📌Core Message:

Prolonged vomiting and diarrhea cause dehydration, manifested by tachycardia, hypotension, a weak pulse, dry mucous membranes, and reduced urinary output.
