Question

The nurse is caring for a client who is at risk for fluid overload due to a history of congestive heart failure. Which priority intervention will the nurse teach the client to perform at home to monitor fluid balance?

Answer 1

Correct Answers:

"Weigh yourself every morning before breakfast."

Rationale :

🔆 Daily weight is the most sensitive and reliable home measurement for detecting changes in fluid volume in a client with congestive heart failure.

🔆 Heart failure can cause sodium and water retention, leading to rapid increases in body weight before severe symptoms become apparent.

🔆 Approximately 1 kg (2.2 lb) of weight gain represents about 1 L of retained fluid, making weight trends useful for monitoring fluid balance.

🔆 The client should weigh at the same time every day, preferably in the morning after voiding and before eating breakfast.

🔆 The client should use the same scale and wear approximately the same amount of clothing to improve measurement consistency.

🔆 A sudden increase in weight can indicate worsening fluid retention and heart failure even before noticeable edema or shortness of breath develops.

🔆 The client should record daily weights and report significant rapid weight gain according to the healthcare provider's instructions, commonly about 2–3 lb (0.9–1.4 kg) in a day or 5 lb (2.3 kg) in a week.

🔆 Early recognition of fluid accumulation allows treatment to be adjusted before the client develops severe pulmonary congestion, edema, or respiratory distress.

Answer 2

Correct Answers:

Fluctuation of the fluid level within the water seal chamber

Rationale :

💎 Tidaling, or fluctuation of fluid in the water-seal chamber, is an expected finding in a functioning chest drainage system.

💎 The fluid level normally rises and falls in response to changes in intrapleural pressure during respiration.

💎 With spontaneous breathing, the water level generally rises during inspiration and falls during expiration.

💎 Tidaling indicates that the chest tube is patent and communicating with the pleural space.

💎 The amount of fluctuation usually decreases as the client's lung re-expands and pleural pressure stabilizes.

💎 Sudden absence of previously observed tidaling can indicate tubing obstruction, dependent kinking, or complete lung re-expansion.

💎 The nurse should routinely assess the tubing for kinks, dependent loops, disconnections, and changes in drainage.

💎 Expected fluctuation in the water-seal chamber therefore indicates that the chest drainage system is functioning appropriately and responding to respiratory pressure changes.

Answer 3

Correct Answers:

Hypomagnesemia

Rationale :

🧿 Chronic heavy alcohol use is strongly associated with magnesium depletion due to poor dietary intake, gastrointestinal losses, and increased renal magnesium excretion.

🧿 The client's statement that he has not eaten a good meal for several months indicates significant malnutrition, further increasing the risk for magnesium deficiency.

🧿 Alcohol can increase urinary magnesium losses by interfering with normal renal tubular reabsorption.

🧿 Gastrointestinal problems associated with chronic alcohol use, including vomiting and diarrhea, can further decrease magnesium levels.

🧿 Hypomagnesemia can cause neuromuscular manifestations such as tremors, muscle cramps, weakness, hyperreflexia, and seizures.

🧿 Severe magnesium deficiency can affect cardiac electrical activity and produce potentially dangerous cardiac dysrhythmias.

🧿 Magnesium deficiency frequently occurs together with hypokalemia and hypocalcemia, making assessment of other electrolytes important.

🧿 The nurse should anticipate monitoring serum magnesium and other electrolytes closely, especially because withdrawal, malnutrition, and subsequent nutritional replacement can produce additional electrolyte abnormalities.

Answer 4

Correct Answers:

Positive Chvostek's sign

Rationale :

🌻 A calcium level of 8.0 mg/dL is below the expected range and indicates hypocalcemia.

🌻 Calcium plays an essential role in maintaining normal neuromuscular stability and nerve conduction.

🌻 Low serum calcium increases the excitability of peripheral nerves and skeletal muscles, producing neuromuscular irritability.

🌻 A positive Chvostek’s sign occurs when tapping the facial nerve anterior to the ear causes involuntary contraction or twitching of the facial muscles.

🌻 Other manifestations of hypocalcemia include muscle cramps, paresthesias, hyperreflexia, and tetany.

🌻 A positive Trousseau’s sign, characterized by carpal spasm after inflation of a blood pressure cuff, can also occur.

🌻 Severe hypocalcemia can cause laryngospasm, seizures, and cardiac dysrhythmias, making continued assessment important.

🌻 The preschooler's low calcium level combined with a positive Chvostek’s sign is therefore consistent with increased neuromuscular excitability caused by hypocalcemia.

Answer 5

Correct Answers:

Elevate the head of the bed

Rationale :

💙 A client reporting shortness of breath requires an immediate intervention that improves ventilation and eases the work of breathing.

💙 Raising the head of the bed places the client in a more upright position, which promotes lung expansion.

💙 Upright positioning decreases pressure from abdominal contents on the diaphragm, allowing more effective respiratory movement.

💙 Elevating the head of the bed can improve oxygenation and ventilation quickly without requiring a prescription.

💙 Low Fowler’s position may not provide enough elevation for a client experiencing acute dyspnea.

💙 Positioning the client first follows the priority principle of addressing an immediate airway and breathing problem.

💙 Once the client is repositioned, the nurse should assess respiratory rate, oxygen saturation, breath sounds, and work of breathing.

💙 Immediate positioning is therefore the best first action because it can rapidly reduce dyspnea while further assessment continues.

Answer 6

Correct Answers:

Altered mental status

Rationale :

♥️ A serum calcium level of 12.3 mg/dL indicates hypercalcemia, which can significantly affect neurologic, gastrointestinal, renal, and cardiac function.

♥️ Hypercalcemia decreases neuromuscular excitability, causing generalized slowing of nervous system activity.

♥️ Neurologic manifestations commonly include lethargy, fatigue, weakness, confusion, and altered mental status.

♥️ As the calcium level rises, the client can develop worsening disorientation, decreased level of consciousness, stupor, or coma.

♥️ Hypercalcemia can also cause gastrointestinal manifestations such as constipation, decreased bowel motility, nausea, and abdominal discomfort.

♥️ Renal manifestations can include polyuria, dehydration, and kidney stone formation because excess calcium affects renal function.

♥️ Cardiac monitoring is appropriate because hypercalcemia can alter cardiac conduction, classically causing a shortened QT interval and potentially dysrhythmias.

♥️ The combination of lethargy and altered mental status is therefore consistent with the decreased neurologic excitability expected with significant hypercalcemia.

Answer 7

Correct Answers:

Hyperglycemia

Rationale :

🤎 Dextrose 10% in water (D10W) contains a relatively high concentration of glucose that is delivered directly into the bloodstream.

🤎 IV dextrose can rapidly increase the client's serum glucose level, particularly when infused continuously or rapidly.

🤎 The pancreas responds to the glucose load by releasing insulin, but the response may be insufficient in susceptible clients.

🤎 Clients with diabetes mellitus, impaired glucose tolerance, severe illness, or pancreatic dysfunction are at increased risk for hyperglycemia.

🤎 Manifestations of hyperglycemia can include polyuria, polydipsia, dehydration, fatigue, and blurred vision.

🤎 The nurse should monitor the client's blood glucose levels during administration, especially when large amounts or prolonged infusions are prescribed.

🤎 Persistent severe hyperglycemia can cause osmotic diuresis, fluid and electrolyte losses, and hyperosmolar complications.

🤎 Monitoring for hyperglycemia is therefore particularly important because D10W provides a substantial intravenous carbohydrate load.

Answer 8

Correct Answers:

Pace physical activity
Obtain yearly influenza immunizations
Adequate caloric intake
Avoid dust and mold

Rationale :

💜 Pace physical activity — CORRECT

💜 Clients with COPD have limited pulmonary reserve and can develop dyspnea and fatigue with physical exertion.

💜 Pacing activities helps decrease excessive oxygen demand and prevents severe shortness of breath.

💜 The client should alternate periods of activity with rest rather than completing strenuous activities continuously.

💜 Frequently used items should be kept within easy reach to reduce unnecessary energy expenditure.

💜 Activities requiring greater energy can be scheduled during times when the client feels most rested.

💜 Pursed-lip breathing can be used during activity to prolong exhalation and reduce air trapping.

💜 Regular activity should still be encouraged because appropriate exercise improves endurance, muscle strength, and functional capacity.

💜 Energy-conservation strategies allow the client to remain as independent and physically active as possible without unnecessarily increasing respiratory workload.

🛡️ Obtain yearly influenza immunizations — CORRECT

🛡️ Respiratory infections can precipitate serious COPD exacerbations and further compromise pulmonary function.

🛡️ Influenza can increase airway inflammation, mucus production, bronchospasm, and oxygen requirements.

🛡️ Clients with COPD are at increased risk for complications and hospitalization from respiratory infections.

🛡️ An annual influenza vaccination decreases the likelihood and severity of influenza infection.

🛡️ Vaccination is an important preventive strategy because COPD exacerbations can accelerate deterioration in lung function and quality of life.

🛡️ The client should also remain current with recommended pneumococcal vaccination according to age and risk-based guidelines.

🛡️ Additional infection-prevention strategies include hand hygiene and avoiding close contact with people who have respiratory infections.

🛡️ Preventing respiratory infection is therefore a major component of long-term COPD health maintenance.

🍽️ Adequate caloric intake — CORRECT

🍽️ Clients with COPD can expend considerable energy because of the increased work of breathing.

🍽️ Chronic respiratory disease can contribute to weight loss and muscle wasting, especially in advanced COPD.

🍽️ Adequate calories and protein help maintain respiratory muscle strength and overall nutritional status.

🍽️ Small, frequent meals are often better tolerated than large meals because gastric distention can increase pressure against the diaphragm.

🍽️ The client may benefit from resting before meals to conserve energy needed for eating and breathing.

🍽️ Foods that are nutrient-dense can provide adequate nutrition without requiring the client to consume excessively large portions.

🍽️ Maintaining a healthy weight supports immune function, physical endurance, and respiratory muscle performance.

🍽️ Adequate caloric intake is therefore an important health-maintenance strategy for preventing malnutrition and weakness in COPD.

🌿 Avoid dust and mold — CORRECT

🌿 Dust and mold are respiratory irritants that can trigger coughing, wheezing, bronchospasm, and worsening dyspnea.

🌿 COPD management includes minimizing exposure to substances that increase airway irritation and inflammation.

🌿 The client should avoid environments with excessive dust, fumes, smoke, and other airborne pollutants whenever possible.

🌿 The home environment should be kept as free as possible from mold and excessive indoor pollutants.

🌿 Exposure to occupational dust or chemical fumes should be minimized using appropriate workplace precautions.

🌿 Tobacco smoke, including secondhand smoke, should also be avoided because it accelerates pulmonary damage.

🌿 Recognizing individual environmental triggers can help reduce the frequency of COPD exacerbations.

🌿 Avoiding respiratory irritants supports better symptom control and helps preserve the client's remaining pulmonary function.

Answer 9

Correct Answers:

Spacer use increases the amount of medication delivered to the lungs

Rationale :

💙 A spacer is a holding chamber attached between a metered-dose inhaler (MDI) and the child's mouth or face mask.

💙 The spacer temporarily holds the aerosolized medication after the inhaler is activated, allowing the child more time to inhale the medication effectively.

💙 Young children often have difficulty coordinating activation of an MDI with simultaneous inhalation, making a spacer especially helpful.

💙 Using a spacer decreases the amount of medication deposited in the mouth and throat.

💙 More medication can therefore travel through the airways and reach the lower respiratory tract and lungs.

💙 When a face mask is used, it should form a secure seal over the child's nose and mouth to maximize medication delivery.

💙 The child can breathe normally through the spacer for several breaths when using an age-appropriate spacer and mask rather than having to perfectly coordinate inhalation.

💙 Improved pulmonary deposition makes the spacer an important tool for increasing the effectiveness of inhaled medications in young children.

Answer 10

Correct Answers:

Respiratory Therapy obtaining an arterial blood gas to check for carbon dioxide retention

Rationale :

🫁 A client with severe emphysema is at risk for chronic and worsening carbon dioxide retention because of impaired alveolar ventilation.

🫁 Increasing confusion and disorientation can be a sign of rising PaCO₂ and worsening respiratory failure.

🫁 An arterial blood gas (ABG) provides direct information about PaCO₂, PaO₂, pH, and the severity of acid-base disturbance.

🫁 A markedly elevated PaCO₂ can cause CO₂ narcosis, leading to headache, confusion, somnolence, and decreased level of consciousness.

🫁 Identifying the ABG pattern helps determine whether the client is developing acute-on-chronic respiratory acidosis.

🫁 The result also helps guide decisions about oxygen therapy, bronchodilator treatment, and possible noninvasive or invasive ventilatory support.

🫁 Mental-status changes in a client with COPD should never be assumed to be simple agitation because they may signal worsening hypoxemia or hypercapnia.

🫁 Obtaining an ABG is therefore the priority anticipated intervention because it rapidly evaluates the potentially life-threatening cause of the client's neurologic deterioration.
