A nurse is providing care for a client who has syndrome of inappropriate antidiuretic hormone secretion (SIADH). Which of the following findings are manifestations of hyponatremia?
(Select All that Apply.)

Urine specific gravity of 1.010 (1.005 - 1.03)

Respiratory alkalosis

Diarrhea

Confusion

Diminished reflexes

Answer and Explanation

Correct Answer : D,E

A. Urine specific gravity of 1.010 (1.005 - 1.03): A urine specific gravity of 1.010 is within the normal range and does not indicate the concentrated urine typically seen in SIADH. Therefore, it is not associated with hyponatremia in SIADH.

B. Respiratory alkalosis: Respiratory alkalosis is related to an imbalance in carbon dioxide levels, not directly to sodium levels. It is not a manifestation of hyponatremia or SIADH.

C. Diarrhea: Diarrhea is not a direct manifestation of hyponatremia. While it can cause electrolyte imbalances, hyponatremia in SIADH is more related to water retention and dilution of sodium.

D. Confusion: Confusion is a common neurological symptom of hyponatremia due to the osmotic imbalance affecting brain cells. This is often seen in clients with SIADH as low sodium levels affect brain function.

E. Diminished reflexes: Diminished reflexes can occur in hyponatremia as it affects neuromuscular function, leading to decreased responsiveness of the nervous system. This can be observed in clients with SIADH.

Correct Answer is B

Explanation

A. Aortic stenosis: While aortic stenosis can cause fatigue and dyspnea, it typically presents with a systolic murmur and symptoms related to reduced blood flow out of the left ventricle, such as syncope or angina. However, tachycardia and weak pulses are less characteristic without advanced disease and heart failure.

B. Heart failure: Dyspnea, fatigue, tachycardia, and weak peripheral pulses are common manifestations of heart failure. The heart's inability to pump effectively leads to reduced cardiac output and poor perfusion of tissues, resulting in these symptoms

C. Asthma: Asthma is characterized primarily by respiratory symptoms like wheezing, shortness of breath, and coughing, especially during an attack. It does not typically cause tachycardia and weak peripheral pulses as a primary manifestation.

D. Aortic valve regurgitation: This condition can lead to symptoms like dyspnea and fatigue due to decreased cardiac efficiency, but it more commonly presents with a diastolic murmur, wide pulse pressure, and a characteristic bounding pulse rather than weak peripheral pulses.

A. Helping the client select a low-salt diet B. Encouraging the client to drink 2 to 3 L of water daily C. Maintaining a semi-Fowler's position as often as possible D. Administering oxygen via nasal cannula at 2 L/min

Correct Answer is B

Explanation

A. Helping the client select a low-salt diet: While a low-salt diet is important for managing conditions like hypertension and heart failure, it does not directly affect the viscosity of bronchial secretions in COPD.

B. Encouraging the client to drink 2 to 3 L of water daily: Increasing fluid intake helps to thin bronchial secretions, making them easier to expectorate. Adequate hydration is essential for patients with COPD to manage mucus and reduce the risk of respiratory infections.

C. Maintaining a semi-Fowler's position as often as possible: This position can help improve lung expansion and ease breathing but does not specifically help in loosening or thinning bronchial secretions.

D. Administering oxygen via nasal cannula at 2 L/min: Oxygen therapy is important for maintaining adequate oxygenation in COPD patients but does not address the issue of tenacious secretions directly.
