A nurse is caring for a client who has hypocalcemia. Which of the following findings should the nurse expect?
Muscle flaccidity
Lethargy
Constipation
Positive Chvostek's sign
The Correct Answer is D
A. Muscle flaccidity: Hypocalcemia typically causes muscle twitching or spasms, not flaccidity. Muscle flaccidity is more often associated with conditions like hyperkalemia or electrolyte imbalances affecting muscle tone in different ways.
B. Lethargy: Lethargy can occur in various conditions, but it is not a hallmark of hypocalcemia. Instead, hypocalcemia usually causes symptoms like irritability, confusion, and muscle cramps rather than general lethargy.
C. Constipation: Constipation is more commonly associated with hypercalcemia, not hypocalcemia. Low calcium levels tend to cause neuromuscular and cardiac symptoms rather than gastrointestinal issues like constipation.
D. Positive Chvostek's sign: A positive Chvostek's sign, which is a twitching of the facial muscles when tapping the facial nerve, is a classic sign of hypocalcemia. It indicates increased neuromuscular excitability, which is characteristic of low calcium levels.

Correct Answer is A
Explanation
A. Place a vibrating tuning fork against the midline vertex of the client's head: The Weber test is performed by placing a vibrating tuning fork on the midline of the client's forehead or vertex of the head. This tests for lateralization of sound, helping to distinguish between conductive and sensorineural hearing loss based on which ear hears the sound louder.
B. Have the client repeat a phrase spoken by the nurse while the nurse's mouth is hidden: This action refers to the "speech discrimination test" rather than the Weber test. It is not part of the Weber test, which is specifically used to assess the lateralization of sound.
C. Whisper words for the client to identify: This refers to a different hearing test, called the "whisper test," used to assess hearing ability, not the Weber test. The Weber test specifically uses a tuning fork to assess how sound is heard by the client.
D. Ask the client to occlude one ear with a finger: While blocking one ear can be used in other tests (like Rinne's test), it is not necessary for the Weber test, which involves placing the tuning fork in the center of the head.
Correct Answer is C
Explanation
A. Projection: Projection involves attributing one’s own undesirable feelings or thoughts onto others. This is not applicable here, as the client is not projecting their behavior onto someone else.
B. Sublimation: Sublimation is the process of channeling negative or unacceptable impulses into socially acceptable activities. Smoking due to anxiety is not an example of channeling impulses into a productive or acceptable activity.
C. Rationalization: Rationalization is a defense mechanism where a person justifies or makes excuses for their behavior or feelings. In this case, the client is justifying smoking as a way to manage anxiety, which is a classic example of rationalization.
D. Dissociation: Dissociation involves a detachment from reality or a separation of thoughts, identity, or consciousness, typically as a coping mechanism in response to trauma or stress. It is not applicable in this situation, where the client is not detaching from reality.
