Which nursing intervention is highest priority for the client who has suffered an acute anterior wall mycordial infarction?

Maintaining strict bedrest for first 24 hours

Measuring urine output hourly and performing daily weighs

Keeping the environment quiet to decrease cardiac workload

Reducing oxygen demand and providing pain control

Answer and Explanation

The Correct Answer is D

A) Maintaining strict bedrest for first 24 hours:
While bedrest is often recommended in the early stages following a myocardial infarction (MI), the priority nursing intervention is to reduce oxygen demand on the heart, which can be achieved through pain management and controlling the workload on the heart, rather than solely relying on bedrest. Bedrest alone may not address the underlying physiological needs of the heart, such as reducing ischemia or controlling pain.

B) Measuring urine output hourly and performing daily weights:
Monitoring urine output and performing daily weights are important in managing fluid balance, especially for those with heart failure or volume overload. However, in the acute phase of an anterior wall myocardial infarction, the priority intervention is addressing the oxygen demand on the heart and providing pain relief, which is more immediate in stabilizing the client and reducing myocardial injury.

C) Keeping the environment quiet to decrease cardiac workload:
While creating a calm and quiet environment helps in reducing stress and decreasing cardiac workload, it is still secondary to actively managing the oxygen demand of the heart. Decreasing the workload of the heart is essential, but this is done more effectively through interventions such as pain management, oxygen therapy, and medications that reduce myocardial oxygen demand (e.g., nitroglycerin, beta-blockers).

D) Reducing oxygen demand and providing pain control:
This is the highest priority intervention for a client who has suffered an acute anterior wall myocardial infarction (MI). Pain from an MI increases the heart's oxygen demand and can exacerbate ischemia. Pain relief, often with morphine, not only reduces pain but also helps in vasodilation, reducing the heart's workload. Additionally, oxygen therapy should be given to ensure adequate oxygenation, and medications like beta-blockers, nitroglycerin, and ACE inhibitors are used to reduce the workload of the heart.

Correct Answer is ["A","D","E"]

Explanation

A) If there is a QRS complex after each P wave:
This is an important consideration when identifying a cardiac rhythm. The P wave represents atrial depolarization, and the QRS complex represents ventricular depolarization. In a normal sinus rhythm, every P wave is followed by a QRS complex, which confirms that the impulse originating in the SA node is being conducted properly through the atrioventricular (AV) node and into the ventricles. The presence of a QRS after every P wave helps confirm normal conduction and rhythm.

B) The rate using only a 3-second strip:
While the heart rate is an essential part of the rhythm assessment, using only a 3-second strip is not the most accurate method for determining the rate. Typically, a 6-second strip is used to estimate the rate, multiplying the number of R-R intervals by 10 to obtain the heart rate. A 3-second strip can be used for quick estimates but may lead to inaccurate calculations of the heart rate.

C) The duration of the U waves:
The U wave is often a normal variant seen in the ECG and is not always present. If it is visible, its duration is typically not a primary focus in rhythm interpretation unless there are concerns about electrolyte imbalances, such as hypokalemia. The U wave is not a core factor to consider when identifying the overall rhythm.

D) If the P waves are present:
The presence of P waves is important for identifying the rhythm, particularly when differentiating between sinus rhythms (normal) and non-sinus rhythms (such as atrial arrhythmias). In normal sinus rhythm, P waves should be present, reflecting atrial depolarization initiated by the SA node. The absence of P waves can indicate atrial fibrillation, atrial flutter, or other arrhythmias.

E) If the P-P and R-R distances are equal:
This is crucial in identifying a regular rhythm. The P-P interval refers to the distance between successive P waves (atrial depolarization), and the R-R interval refers to the distance between successive R waves (ventricular depolarization). In normal sinus rhythm or regular rhythms, both the P-P and R-R intervals should be equal, indicating that the atrial and ventricular rhythms are consistent. If they are unequal, it suggests an irregular rhythm (e.g., atrial fibrillation).

A. chemical burns to the posterior neck, chest, and back B. radiation burns to shoulder and bridge of nose C. electrical burns to the hands causing dysrhythmias D. thermal burns to the head, neck, face, and airway.

Correct Answer is D

Explanation

A) Chemical burns to the posterior neck, chest, and back:
Chemical burns primarily affect the skin and underlying tissues where the chemicals have come into contact. Although chemical burns can cause significant damage, particularly to the respiratory system if inhaled, chemical burns to the posterior neck, chest, and back would not typically require endotracheal intubation or tracheostomy unless there is evidence of inhalation injury or airway compromise.

B) Radiation burns to shoulder and bridge of nose:
Radiation burns, such as those from sunburn or therapeutic radiation, generally do not cause immediate airway compromise or respiratory distress unless the radiation exposure has affected the lungs or upper respiratory tract.

C) Electrical burns to the hands causing dysrhythmias:
Electrical burns can cause significant tissue damage, especially if there is a deep tissue injury and potential for electrical burns to the internal organs. They can lead to dysrhythmias, but these burns are more related to cardiac complications rather than direct airway injury. Endotracheal intubation may be required if there are signs of airway compromise or respiratory failure, but the primary concern with electrical burns would be cardiac monitoring and fluid resuscitation.

D) Thermal burns to the head, neck, face, and airway:
The upper airway (including the mouth, throat, and vocal cords) is particularly vulnerable to thermal injury from inhaling hot gases, smoke, or steam. This can lead to edema and airway obstruction, which can rapidly progress to respiratory failure. Endotracheal intubation or even a tracheostomy may be required to secure the airway and prevent suffocation. Inhalation injury is a significant concern in thermal burns involving the head, neck, and face.
