A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?

Inverted P wave

Wide ORS

Elevated ST segment

Abnormally prominent U wave

Answer and Explanation

The Correct Answer is D

A. Inverted P wave: An inverted P wave may indicate atrial depolarization abnormalities but is not typically associated with hypokalemia. It can be seen in conditions such as atrial enlargement or atrial ischemia. However, in hypokalemia, the P wave may become flattened or have a decreased amplitude, but it is less likely to be inverted.
B. Wide QRS: A wide QRS complex may indicate conduction abnormalities or bundle branch blocks, but it is not specifically associated with hypokalemia. Wide QRS complexes are more commonly seen in conditions such as bundle branch blocks or electrolyte imbalances like hyperkalemia. Hypokalemia tends to cause a prolongation of the QT interval rather than widening of the QRS complex.
C. Elevated ST segment: An elevated ST segment is typically associated with myocardial injury or infarction, not hypokalemia. It can be indicative of conditions such as myocardial ischemia or pericarditis. In hypokalemia, ST segment changes are more likely to be flattened or depressed rather than elevated.
D. Abnormally prominent U wave: An abnormally prominent U wave is a classic EKG finding in hypokalemia. Hypokalemia prolongs the repolarization phase of the cardiac action potential, leading to the appearance of U waves following the T wave. These U waves can become more pronounced as potassium levels decrease. Therefore, an abnormally prominent U wave is a significant indicator of hypokalemia on an EKG, especially in a patient with prolonged vomiting, which can lead to potassium depletion. Thus, it is the most pertinent abnormality to interpret in this context.

Correct Answer is B, C, A, D

Explanation

Answer: B, C, A, D Rationale: B (Rescue the clients): The immediate priority in any fire situation is to ensure the safety of individuals, which includes removing clients from danger. C (Pull the fire alarm): After clients are safe, the next step is to alert others of the fire and call for assistance. A (Confine the fire): Once the alarm is activated, the fire should be contained by closing doors or windows to prevent it from spreading. D (Extinguish the fire): If it is safe to do so, the fire should be extinguished using the appropriate equipment. If not, evacuation is the next step.

A. Polyuria B. Hypotension C. Weakened gag reflex D. Hyperthermia E. Absence of bowel sounds

Correct Answer is ["B","C","E"]

Explanation

A. Polyuria: Polyuria, or excessive urination, is not typically associated with cervical spinal cord injury. In fact, urinary retention or neurogenic bladder is more commonly observed due to disruption of bladder control. Clients with cervical spinal cord injury often experience bladder dysfunction, which can lead to urinary retention rather than polyuria.
B. Hypotension: Hypotension is a common complication of cervical spinal cord injury, particularly in cases involving injury above the level of T6. Damage to the sympathetic nervous system can result in neurogenic shock, characterized by vasodilation and bradycardia, leading to hypotension. Monitoring for signs of hypotension, such as decreased blood pressure and altered mental status, is essential for early intervention and prevention of complications.
C. Weakened gag reflex: Cervical spinal cord injury can impair the gag reflex due to disruption of the glossopharyngeal nerve (CN IX) and vagus nerve (CN X) function. This impairment can lead to difficulty swallowing, aspiration risk, and increased susceptibility to respiratory complications such as aspiration pneumonia. Therefore, monitoring the gag reflex and assessing for signs of dysphagia are crucial in clients with cervical spinal cord injury to prevent respiratory compromise and aspiration-related complications.
D. Hyperthermia: Hyperthermia is less commonly associated with cervical spinal cord injury. However, in some cases, autonomic dysreflexia—a potentially life-threatening condition—can occur, leading to increased body temperature among other symptoms. This is more common in injuries above the T6 level.
E. Absence of bowel sounds: Neurogenic bowel dysfunction, including the absence of bowel sounds, is a common complication of cervical spinal cord injury. Disruption of autonomic nervous system function can lead to decreased peristalsis and absent bowel sounds.
