A nurse is performing Weber's test for a client who has hearing loss. Which of the following actions should the nurse take?

A. Notify the primary care provider: Notifying the provider is important, but first, the nurse should assess the client’s condition by obtaining vital signs. This helps determine if immediate intervention is needed, like administering antidotes or treatments.

B. Obtain the client's vital signs: The first step is assessing the client’s physical status by checking vital signs. This helps identify signs of toxicity or immediate adverse effects from the overdose, guiding further actions.

C. Educate the client about potential adverse effects: Education is important, but it’s not the first priority in the case of an overdose. The nurse should first focus on assessing and stabilizing the client before providing information on potential adverse effects.

D. Complete an incident report: While an incident report is necessary, it is not the immediate priority. The nurse must first ensure the client’s safety and health by assessing and managing the overdose.

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.
