A nurse who is left-handed is preparing to perform a straight catheterization for a client. Which of the following actions should the nurse take?

A) Anxiety: Anxiety is a subjective finding because it represents the client's perception of their emotional state. It is a feeling of unease, worry, or fear, which the client reports experiencing. Subjective findings are based on the client's self-report or feelings.

B) Alert: Being alert is an objective finding because it refers to the client's level of consciousness and responsiveness to stimuli. In this scenario, the nurse assesses that the client is alert based on their ability to respond appropriately to questions and stimuli in the environment.

C) Pacing: Pacing is an objective finding because it describes observable behavior. In this case, the nurse observes the client pacing in the room, which is a physical activity that can be seen or measured.

D) Restless: Restlessness is an objective finding because it describes observable behavior. The nurse assesses that the client appears restless based on their observed behavior of pacing in the room. Restlessness is a physical manifestation of the client's anxiety and is observable by others.

A. Light-headedness when standing up:
Elevated potassium levels (hyperkalemia) can lead to muscle weakness or paralysis, cardiac dysrhythmias, and even cardiac arrest. Light-headedness when standing up is more commonly associated with orthostatic hypotension or volume depletion rather than electrolyte imbalances like hyperkalemia.

B. Weak quadriceps muscles:
Weakness in the quadriceps muscles is not typically associated with the electrolyte imbalances presented in the scenario. Hyperkalemia can cause muscle weakness, but it is not specific to the quadriceps.

C. Decreased deep tendon reflexes:
Decreased deep tendon reflexes are not typically associated with the electrolyte imbalances presented in the scenario. Hyperkalemia can lead to hyperreflexia or absent reflexes, but it is not specific to decreased deep tendon reflexes.

D. Tingling of extremities:
This is the correct answer. Hypocalcemia, indicated by the low calcium level in the scenario, can manifest with symptoms such as tingling or numbness of the extremities, muscle cramps, and tetany. Calcium plays a crucial role in nerve transmission, and low levels can lead to sensory disturbances like tingling in the extremities.
