A nurse is collecting data from a client who has a sodium level of 128 mEq/L. Which of the following manifestations should the nurse expect?
Hyporeflexia.
Constipation.
Increased appetite.
Headache.
The Correct Answer is D
The correct answer is Choice D: Headache.
Rationale for Choice D (Headache): Hyponatremia, defined as a serum sodium level below 135 mEq/L, can lead to various neurological symptoms due to the altered osmotic pressure in the brain cells. When the sodium level drops below normal, water moves into the cells, causing them to swell, which can lead to increased intracranial pressure and subsequent headaches. Therefore, a client with a sodium level of 128 mEq/L is likely to experience headaches as a manifestation of hyponatremia.
Rationale for other choices:
Choice A: Hyporeflexia Hyporeflexia refers to diminished or absent reflexes. While hyponatremia can affect neurological function, hyporeflexia is not a typical manifestation. Instead, hyperreflexia may occur in severe cases due to cerebral edema and increased intracranial pressure.
Choice B: Constipation Constipation is not a common manifestation of hyponatremia. Gastrointestinal symptoms such as nausea, vomiting, and abdominal cramping may occur, but constipation is not typically associated with sodium imbalances.
Choice C: Increased appetite Hyponatremia does not typically cause increased appetite. Instead, gastrointestinal symptoms such as nausea and anorexia are more commonly observed. Increased appetite is not directly related to sodium levels but may be seen in conditions such as hyperthyroidism or certain medications.
Therefore, based on the provided data and typical manifestations of hyponatremia, the correct answer is Choice D: Headache. This is because headaches are a common neurological symptom associated with low sodium levels and increased intracranial pressure.

Correct Answer is D
Explanation
Choice A rationale:
Cool, clammy skin is not a typical manifestation of hypernatremia (high sodium levels). Hypernatremia is characterized by an excess of sodium in the blood, which typically leads to symptoms such as thirst, dry mucous membranes, and decreased skin turgor. Cool, clammy skin is more often associated with conditions like shock or hypoglycemia.
Choice B rationale:
Increased salivation is not a common manifestation of hypernatremia. Instead, hypernatremia often leads to signs of dehydration, including dry mouth and decreased salivation.
Choice C rationale:
Hypertension is not a direct manifestation of hypernatremia. Hypernatremia can cause increased blood pressure, but it is not one of the typical clinical signs of hypernatremia. Hypertension is more commonly associated with conditions like high sodium intake, kidney disease, or primary hypertension.
Choice D rationale:
A decreased level of consciousness is a significant manifestation of hypernatremia. Elevated sodium levels in the blood can lead to cellular dehydration, affecting brain cells and resulting in neurological symptoms such as confusion, lethargy, and decreased consciousness. Severe hypernatremia can even lead to seizures and coma. .
Correct Answer is A
Explanation
Choice A rationale:
The nurse should prioritize collecting data from a client who reports unilateral calf pain when ambulating. This symptom could indicate the presence of a deep vein thrombosis (DVT), a potentially life-threatening condition. DVT occurs when a blood clot forms in a deep vein, often in the lower extremities. If left untreated, the clot can dislodge and travel to the lungs, causing a pulmonary embolism. Immediate assessment is crucial to rule out DVT and provide appropriate interventions. The nurse should assess the client's calf for swelling, redness, warmth, and tenderness and may also order diagnostic tests like a duplex ultrasound.
Choice B rationale:
Taking a telephone prescription for a client being transferred from the PACU is important but not the top priority in this situation. While timely transfer and adequate post-operative care are essential, addressing a client with unilateral calf pain and the potential for a DVT takes precedence due to the risk of a life-threatening complication.
Choice C rationale:
Reassuring the partner of a client who sustained a closed head injury is a compassionate action but should not be the first priority. The partner's emotional support can be provided once the immediate medical concerns have been addressed.
Choice D rationale:
Reinforcing a client's dressing on an above-the-knee amputation surgical site is important for the client's post-operative care, but it is not the highest priority when compared to the possibility of a DVT. The nurse should address the client's calf pain first and then attend to the dressing reinforcement.
