A client's serum potassium level is approaching 7 mEq/L. Which physical assessment would the nurse prioritize based on this serum lab value?

Cardiac

Gastrointestinal

Respiratory

Neurologic

Answer and Explanation

The Correct Answer is A

A. Hyperkalemia can have significant cardiac effects, potentially leading to life-threatening arrhythmias such as bradycardia, heart block, ventricular tachycardia, or ventricular fibrillation. As potassium levels rise, it affects the electrical conduction of the heart, leading to changes in the ECG (electrocardiogram) and potentially causing fatal arrhythmias.

B. While hyperkalemia primarily affects the cardiovascular system, gastrointestinal symptoms can also occur. These may include nausea, vomiting, abdominal pain, and diarrhea. However, these symptoms are typically less severe compared to cardiac manifestations. Monitoring for gastrointestinal symptoms helps in assessing overall clinical status but is not as critical as assessing cardiac function in the context of hyperkalemia.

C. Respiratory symptoms are not typically associated with hyperkalemia unless severe acid-base disturbances are present. Potassium imbalance itself does not directly affect respiratory function. Therefore, while it is important to assess respiratory status in any client, it is not the priority in the context of hyperkalemia.

D. Hyperkalemia can affect the nervous system, leading to symptoms such as muscle weakness, tingling sensations, and even paralysis in severe cases. However, neurologic symptoms usually occur at higher potassium levels or in the presence of significant electrolyte imbalances affecting nerve function.

Monitoring for neurologic symptoms is important but is generally secondary to assessing cardiac status in the context of approaching severe hyperkalemia.

Correct Answer is B

Explanation

B. This response acknowledges the urgency of the situation and seeks clarification on the appropriate administration technique. It demonstrates readiness to follow through with the medical resident's directive while ensuring safe and effective administration.

A. This response reflects hesitation and a concern about administering a medication that the nurse did not prepare or is unfamiliar with. In a critical situation like a "code blue," timely administration of medications as directed by the medical team is crucial for patient outcomes.

C. Checking IV patency is important to ensure the medication can be administered properly. However, in a "code blue" situation where time is critical, this step might unnecessarily delay administration of the medication.

D. This response indicates willingness to follow the directive given by the medical resident. It also emphasizes the importance of documenting and obtaining proper orders after the immediate crisis has been addressed.

A. Reduce environmental stimuli B. Suction the oropharynx C. Assess pulse oximetry D. Administer oxygen

Correct Answer is A

Explanation

A. Restlessness and agitation in nonverbal clients can often be exacerbated by environmental factors such as noise, bright lights, or unfamiliar surroundings. By reducing environmental stimuli, such as dimming lights, minimizing noise, and providing a calm atmosphere, the nurse can help alleviate agitation and promote a more comfortable environment for the client.

B. Suctioning the oropharynx is not typically the first action unless there is a clear indication that airway obstruction or secretion management is contributing to the client's agitation. It is important to first assess whether there are signs of respiratory distress or airway compromise before performing suctioning.

C. Assessing pulse oximetry is important for monitoring oxygen saturation levels, especially if there are concerns about respiratory distress or inadequate oxygenation. However, it is not typically the first action when a client is restless and agitated unless there are specific indications or signs suggesting respiratory compromise.

D. Administering oxygen may be necessary if there are signs of hypoxia or respiratory distress contributing to the client's agitation. However, without assessing the client's oxygenation status first, administering oxygen as the initial action may not address the underlying cause of agitation.
