A patient began to have hand and face tremors after being brought into the Emergency Department. Labs were immediately drawn on this patient. Which labs would most likely concern the nurse at this time?
Chloride 100 mEq/L
Sodium 138 mEq/L
Oc) Potassium 4.1 mEq/L
Magnesium 1.0 mEq/L
The Correct Answer is D
a) Chloride 100 mEq/L: A chloride level of 100 mEq/L is within the normal range (98-107 mEq/L) and would not be concerning in this context.
b) Sodium 138 mEq/L: A sodium level of 138 mEq/L is within the normal range (135-145 mEq/L) and would not be concerning in this context.
c) Potassium 4.1 mEq/L: A potassium level of 4.1 mEq/L is within the normal range (3.5-5.0 mEq/L) and would not be concerning in this context.
d) Magnesium 1.0 mEq/L: A magnesium level of 1.0 mEq/L is low (normal range: 1.5-2.5 mEq/L), and low magnesium can cause neuromuscular symptoms such as tremors. This would be a concerning result in the context of the patient's hand and face tremors.

Correct Answer is A
Explanation
a) Clear Liquid Diet: A clear liquid diet consists of liquids that are clear at room temperature, such as broth, tea, and clear juices. It requires minimal digestion and leaves minimal residue, making it ideal for clients with gastrointestinal issues, post-surgery, or before certain diagnostic tests.
b) Renal Diet: A renal diet is designed for patients with kidney disease and focuses on limiting protein, sodium, potassium, and phosphorus intake. It is not composed solely of clear liquids.
c) Mechanically Altered Diet: A mechanically altered diet involves foods that are chopped, pureed, or ground to aid in chewing or swallowing, not just clear liquids.
d) Pureed Diet: A pureed diet consists of foods that are blended or mashed into a smooth consistency, not clear liquids that become fluid at body temperature.
Correct Answer is A
Explanation
a) A slowing of the client's heart rate: The Valsalva maneuver (straining during defecation) can cause a transient increase in intra-abdominal pressure, which triggers vagal stimulation, leading to a slowing of the heart rate (bradycardia).
b) A decrease in the client's blood pressure: The Valsalva maneuver may initially cause an increase in blood pressure, followed by a drop after the maneuver is released. The immediate effect is a slowing of the heart rate, not a decrease in blood pressure.
c) An increase in the client's respiratory rate: The Valsalva maneuver typically causes a temporary decrease in respiratory rate due to the strain on the body.
d) A decrease in the client's respiratory rate: The Valsalva maneuver does not typically result in a significant decrease in respiratory rate. Instead, it is more likely to cause a brief alteration in heart rate and blood pressure.
