A nurse is assessing a client who has an oral temperature of 39 C (102.27 F). Which of the following findings should the nurse expect?
Decreased peripheral pulses
Heart rate 108/min
Respiratory rate 10 breathes/min
Dilated pupils
The Correct Answer is B
A) Decreased peripheral pulses:
Increased body temperature typically causes vasodilation rather than vasoconstriction, leading to improved blood flow rather than decreased. As a result, peripheral pulses are more likely to be normal or even increased in response to fever. Decreased peripheral pulses would be more indicative of conditions like shock or hypoperfusion, not fever.
B) Heart rate 108/min:
Fever causes an increase in metabolic demand, which often results in a compensatory increase in heart rate (tachycardia). This phenomenon, known as "fever tachycardia," occurs as the body attempts to circulate blood more rapidly to meet the increased oxygen and nutrient demands caused by elevated body temperature. A heart rate of 108 beats per minute is a normal response to fever, particularly when the temperature reaches 39°C (102.27°F).
C) Respiratory rate 10 breaths/min:
A respiratory rate of 10 breaths per minute is considered bradypnea (abnormally slow breathing), which is typically not associated with fever. Fever usually leads to an increase in respiratory rate (tachypnea) as the body attempts to cool itself through increased evaporation of sweat and breathing. A respiratory rate of 10 breaths/min is more likely to be seen in conditions like drug overdose, head injury, or respiratory depression, rather than fever.
D) Dilated pupils:
Dilated pupils (mydriasis) are typically associated with sympathetic nervous system activation, which can be caused by certain drugs, trauma, or neurological conditions. Fever, however, generally causes only mild changes in pupil size and is more likely to lead to constricted pupils (miosis) in response to certain stress hormones. Dilated pupils are not a typical finding with fever.

Correct Answer is B
Explanation
A) Chloride 112:
Chloride levels are typically not directly associated with numbness or tingling of the hands and fingers. Elevated chloride levels (greater than 108 mEq/L) may indicate metabolic acidosis, but they would not directly explain the symptoms seen in this client following parathyroidectomy. Therefore, this value is unlikely to be relevant in this scenario.
B) Calcium 7.5:
After the partial removal of the parathyroid glands, the client may experience hypocalcemia, or low calcium levels, due to the reduced production of parathyroid hormone (PTH). PTH helps regulate calcium levels in the blood. When the parathyroid glands are removed or damaged, there may be insufficient PTH to maintain normal calcium levels, leading to hypocalcemia. Symptoms of hypocalcemia include numbness and tingling, especially in the hands and fingers. A calcium level of 7.5 mg/dL is below the normal range (8.5–10.5 mg/dL), indicating hypocalcemia, which is consistent with the patient's symptoms.
C) Potassium 4.0:
A potassium level of 4.0 mEq/L is within the normal range (3.5–5.0 mEq/L) and does not typically cause numbness or tingling. Although potassium imbalances can cause neuromuscular symptoms, they would not be the most likely cause of the symptoms in this case, especially in relation to parathyroidectomy.
D) Calcium 12.1:
A calcium level of 12.1 mg/dL is elevated and would suggest hypercalcemia. Hypercalcemia can cause symptoms like fatigue, confusion, and weakness, but it does not typically cause numbness and tingling in the hands and fingers. Elevated calcium levels are more likely to occur in conditions such as hyperparathyroidism or malignancy, not typically following parathyroid gland removal. Therefore, this is not the expected lab result in this scenario.
Correct Answer is A
Explanation
A) Potassium level 3 mEq/L:
A potassium level of 3 mEq/L is below the normal range (which is typically 3.5-5.0 mEq/L) and represents hypokalemia. Potassium is crucial for normal muscle and nerve function, including cardiac function. Low potassium levels can lead to dangerous arrhythmias, muscle weakness, and cardiac arrest if not addressed promptly. This is the priority value because hypokalemia can be life-threatening and requires immediate attention from the healthcare provider to correct the imbalance.
B) BUN 9.5 mg/dl:
A BUN (blood urea nitrogen) level of 9.5 mg/dL is within the normal reference range for most adults (typically 7-20 mg/dL). While an abnormal BUN level could indicate kidney dysfunction or dehydration, this value is not immediately concerning and does not represent a critical finding that requires urgent attention.
C) Creatinine 0.4 mg/dl:
A creatinine level of 0.4 mg/dL is below the normal range (usually around 0.6-1.2 mg/dL), which might indicate low muscle mass or a transient decrease in kidney function. However, a low creatinine level is generally not as urgent or concerning as an elevated level, and it does not typically require immediate intervention
D) Sodium 135 mEq/L:
A sodium level of 135 mEq/L is slightly below the normal range (135-145 mEq/L), indicating mild hyponatremia. Although this can be concerning if the drop is acute or symptomatic (e.g., causing confusion, seizures, or lethargy), a mild decrease in sodium is not immediately life-threatening unless it worsens rapidly.
