ATI NUR 213 Midpoint Assessment

Correct Answer:

For maintaining muscle strength

Detailed Explanation:

Patients with tuberculosis (TB), especially those who are hospitalized, on prolonged bed rest, or experiencing significant fatigue, are at risk for muscle weakness, deconditioning, and joint stiffness due to inactivity. Performing active range-of-motion (ROM) exercises three times a day is essential for maintaining muscle strength, joint mobility, and circulation.

How Active ROM Exercises Help TB Patients:

Prevention of Muscle Atrophy:

Prolonged bed rest or reduced physical activity leads to muscle atrophy (wasting), making daily activities more difficult. Regular ROM exercises keep muscles engaged and active, preventing loss of strength.

Maintenance of Joint Mobility:

Inactivity can cause joint stiffness and reduced flexibility. ROM exercises help keep the joints mobile and functional, reducing stiffness and discomfort.

Improvement in Blood Circulation:

Movement stimulates blood flow, reducing the risk of venous stasis and deep vein thrombosis (DVT), which can occur in immobilized patients. Good circulation also enhances oxygen and nutrient delivery to tissues, promoting overall recovery.

Respiratory Benefits:

TB affects the lungs, and prolonged immobility can worsen respiratory function. Moving and engaging in light activity helps improve lung expansion, prevent pneumonia, and aid in clearing secretions.

Psychological Well-Being:

Patients who engage in regular movement often experience improved mood, reduced stress, and enhanced motivation to participate in their own care.

Why the Other Options Are Incorrect:

For medication absorption –

TB medications (e.g., isoniazid, rifampin, ethambutol, pyrazinamide) are absorbed through the gastrointestinal tract, not influenced by physical movement. ROM exercises do not enhance or affect medication absorption in any way.

For use as a baseline for evaluation –

While assessing ROM can help monitor physical function over time, the primary reason for performing ROM exercises is to maintain strength and prevent complications. ROM exercises are therapeutic, not just a measurement tool. For effective pain control

TB-related pain (such as chest pain, joint pain, or discomfort from coughing) is not primarily managed through ROM exercises. Pain is typically managed with medications, breathing exercises, and positioning. While movement may help reduce stiffness-related discomfort, it is not the primary intervention for pain relief.

Conclusion:

Encouraging a patient with tuberculosis to perform active ROM exercises three times a day is crucial for maintaining muscle strength, joint mobility, circulation, and overall physical function. This helps prevent muscle atrophy, stiffness, and complications associated with prolonged immobility.

Correct Answer: B. Slow the amiodarone infusion rate.

Why It Is Correct

Amiodarone is an antiarrhythmic medication that can cause bradycardia (slow heart rate) as a side effect. The client’s heart rate has dropped from 68 bpm to 50 bpm since starting the infusion, and the rhythm has changed to sinus bradycardia. The client is still alert, oriented, and asymptomatic (no chest pain, shortness of breath, or dizziness), meaning immediate discontinuation is unnecessary, but the infusion rate should be adjusted. Slowing the infusion rate is the appropriate action to manage bradycardia while maintaining therapeutic effects.

Why the Other Options Are Incorrect

A. Stop the infusion and flush the IV.

The client is not experiencing severe symptoms such as hypotension, altered mental status, or significant distress. Complete discontinuation is unnecessary at this stage.

C. Administer IV normal saline.

There is no sign of hypovolemia or dehydration that would require fluid resuscitation. Bradycardia related to amiodarone toxicity is not treated with IV fluids.

D. Ask the client to cough and deep breathe.

Coughing and deep breathing are useful for managing hypoxia or atelectasis, not for medication-induced bradycardia. The client’s oxygen saturation is stable (95%), and they have no respiratory distress.

Summary

Since the client is developing sinus bradycardia but remains asymptomatic, the best intervention is to slow the amiodarone infusion rate to prevent further heart rate decline while maintaining its antiarrhythmic effects

Correct Answer:

Assess for any hemodynamic effects of the rhythm.

Explanation:

After a myocardial infarction, the development of dysrhythmias is common due to myocardial irritability and impaired electrical conduction. However, not all dysrhythmias are clinically significant or require immediate intervention. The nurse’s first priority is to assess whether the rhythm is impacting the client’s hemodynamic status—meaning their ability to maintain adequate blood pressure, oxygenation, consciousness, and perfusion. Clinical signs such as hypotension, shortness of breath, chest pain, confusion, or decreased urine output would indicate compromised cardiac output. Only after this assessment can the nurse determine whether further interventions, such as medication or provider notification, are warranted. Without this initial evaluation, responses may be unnecessary or even harmful.

Why Other Options Are Wrong:

Prepare to administer antidysrhythmic medication

Administering antidysrhythmic drugs without confirming that the dysrhythmia is causing clinical symptoms could expose the client to unnecessary side effects. Some antidysrhythmics can depress cardiac function or provoke additional arrhythmias. The decision to medicate should always be based on a thorough assessment of the client's hemodynamic status.

Notify the provider or call the Rapid Response Team

Immediate notification or escalation without assessing the client may be premature. Many dysrhythmias—such as isolated premature ventricular contractions—are benign unless they result in decreased perfusion. Proper assessment guides the urgency of escalation and prevents unnecessary alarm or intervention.

Turn the alarms off on the cardiac monitor

Disabling alarms is dangerous and violates standard monitoring safety protocols. Alarms provide real-time alerts to significant changes in cardiac rhythm and are critical for early intervention. If alarms are too frequent or inappropriate, the parameters may be adjusted to be clinically relevant, but they should never be silenced entirely.

Summary:

The nurse’s first action should be to assess for hemodynamic effects of the rhythm to determine if the dysrhythmia is impacting the client’s stability. This allows for safe and effective decision-making and prevents unnecessary or inappropriate interventions.

Correct Answer:

Assess the client's ankle-brachial index.

Explanation:

The visual presentation of the client’s leg—typically pale, possibly hairless, cool, and possibly with ulcers or diminished pulses—suggests impaired arterial circulation, commonly seen in peripheral arterial disease (PAD). The ankle-brachial index (ABI) is a non-invasive and reliable method to assess the severity of PAD by comparing blood pressure in the ankle with that in the arm. A low ABI confirms poor arterial perfusion and helps guide further management. This assessment is diagnostic and should be performed before other interventions or treatments are initiated.

Why Other Options Are Wrong:

Elevate the client's leg above the heart

While elevation is appropriate for venous insufficiency, it can worsen arterial insufficiency by further reducing blood flow to an already ischemic extremity. Clients with PAD often find relief by dangling the leg to use gravity to improve perfusion. Therefore, elevation is contraindicated in this scenario.

Obtain an ice pack to provide comfort

Applying cold to a limb with compromised circulation may worsen ischemia and discomfort. Clients with PAD often already have poor peripheral perfusion and are sensitive to cold. Ice packs could exacerbate tissue hypoxia and lead to injury.

Prepare to teach about heparin sodium

Heparin is used for conditions involving venous thrombosis, such as deep vein thrombosis (DVT), not PAD. There is no indication from the described limb appearance that an acute thrombotic event is occurring that would require anticoagulation. Initiating teaching about heparin without diagnostic evidence or physician orders would be premature and inappropriate.

Correct Answer:

Schedule periods of exercise and rest during the day.

Explanation:

Fatigue in clients with atrial fibrillation often results from decreased cardiac output and impaired oxygen delivery to tissues. Scheduling balanced periods of exercise and rest helps the client conserve energy while maintaining physical activity to improve overall endurance and cardiovascular health. This approach optimizes functional ability without causing overexertion, which can worsen fatigue.

Why Other Options Are Wrong:

Administer oxygen therapy at 2 liters per nasal cannula.

Oxygen therapy is not routinely indicated for atrial fibrillation unless the client exhibits hypoxia or respiratory distress. Administering oxygen unnecessarily may not improve fatigue and could delay addressing the actual cause.

Provide the client with a sleeping pill to stimulate rest.

Sleep aids may mask symptoms and pose risks such as respiratory depression or dependency. They do not address the underlying cause of fatigue and are generally not recommended without a thorough assessment and provider approval

Ask unlicensed assistive personnel to help bathe the client.

While delegation can assist with activities of daily living, this intervention does not directly address the client's fatigue or teach energy management strategies. Encouraging self-care with pacing activities promotes independence and better management of symptoms.

Correct Answer:

Assess airway, breathing, and level of consciousness.

Explanation:

When a cardiac monitor displays a potentially life-threatening rhythm (such as ventricular tachycardia), the nurse's first priority is to assess the client—not just the monitor. This includes checking the airway, breathing, circulation, and level of consciousness. This assessment determines whether the client is stable or unstable, and whether they have a pulse. These findings guide the urgency and type of intervention—such as CPR for pulselessness or synchronized cardioversion for unstable but perfusing rhythms. Reacting solely to the monitor without assessing the client can result in inappropriate or even harmful interventions.

Why Other Options Are Wrong:

Administer an amiodarone bolus followed by a drip is a treatment for stable ventricular tachycardia with a pulse. However, giving this medication without confirming the client’s stability or presence of a pulse could delay more urgent interventions like CPR or cardioversion if the client is in cardiac arrest or unstable.

Cardiovert the client with a biphasic defibrillator is appropriate for unstable ventricular tachycardia with a pulse. However, cardioversion should not be initiated without first determining if the client is unstable and still has a pulse. Attempting cardioversion on a pulseless client is inappropriate—it would require defibrillation instead.

Begin cardiopulmonary resuscitation (CPR) is necessary if the client is found to be pulseless, which cannot be known until the nurse assesses the client. While this might ultimately be required, it is not the first step—assessment is.

Correct Answer:

C) Pulmonary embolism

Explanation:

External pneumatic compression stockings (also called sequential compression devices, or SCDs) help prevent deep vein thrombosis (DVT) by promoting venous blood flow in the legs. Postoperative patients, especially elderly individuals and those who are immobile, are at a high risk of developing blood clots in their deep veins due to venous stasis (slow blood flow). If a DVT forms and dislodges, it can travel to the lungs, causing a pulmonary embolism (PE)—a life-threatening condition.

Why the Other Choices Are Incorrect:

A) Sepsis

Incorrect because sepsis is a systemic infection, typically resulting from surgical site infections, pneumonia, or urinary tract infections. Not wearing compression stockings does not directly increase the risk of sepsis.

B) Infection

Incorrect because infections are primarily related to surgical wounds, invasive devices (e.g., catheters), or poor hygiene. While prolonged immobility can weaken the immune response, it does not directly cause infections.

D) Hematoma

Incorrect because a hematoma is a localized collection of blood outside the blood vessels, usually caused by surgical trauma or injury. Not wearing compression stockings does not increase the risk of hematoma formation.

Summary:

Refusing to wear external pneumatic compression stockings significantly increases the risk of deep vein thrombosis (DVT), which can lead to a pulmonary embolism (PE). PE is a serious, potentially fatal complication, making patient education and compliance with compression therapy essential in postoperative care.

Correct Answer:

Disorientation and confusion

Explanation:

Older adults often present with atypical signs and symptoms during a myocardial infarction (MI). Rather than the classic crushing chest pain seen in younger individuals, elderly patients may experience subtle or nonspecific symptoms due to age-related physiological changes and comorbidities. Disorientation and confusion in this population can result from decreased cerebral perfusion during cardiac ischemia. Cognitive changes may be the only manifestation of an MI in an older adult, particularly those with baseline cognitive impairment or concurrent illness. This makes thorough assessment and high clinical suspicion essential when evaluating changes in mental status in elderly patients.

Why Other Options Are Wrong:

Excruciating pain on inspiration

This symptom is more typical of pleuritic pain, such as that seen in pulmonary embolism or pleurisy, rather than myocardial infarction. Pleuritic pain is sharp, worsens with inspiration, and is usually localized to the chest wall. Myocardial infarction pain is usually described as pressure-like, squeezing, or a heavy sensation that is not affected by breathing. Therefore, while chest pain is associated with MI, pain that worsens specifically with inspiration is not characteristic.

Left lateral chest wall pain

Although chest pain can be a symptom of myocardial infarction, pain localized to the left lateral chest wall is more commonly associated with musculoskeletal causes or costochondritis. The pain of an MI typically originates in the center or left side of the chest and may radiate to the jaw, neck, shoulder, or arm, but it is usually not confined to a specific chest wall region. In older adults, classic pain patterns may not occur at all, making this presentation less likely.

Numbness and tingling of the arm

While arm discomfort, particularly in the left arm, can be a classic symptom of MI, numbness and tingling specifically are more indicative of neurological or musculoskeletal issues, such as nerve compression or peripheral neuropathy. Myocardial infarction pain that radiates to the arm is typically described as a dull ache or pressure, not as paresthesia. Relying on sensory symptoms like numbness and tingling can mislead clinical judgment away from the more relevant systemic and cognitive changes that often accompany MI in elderly patients.

Correct Answer: B. Dyspnea on exertion

Explanation:

Mitral valve stenosis leads to narrowing of the mitral valve, causing impaired blood flow from the left atrium to the left ventricle. As the stenosis worsens, pressure increases in the left atrium, leading to pulmonary congestion and dyspnea on exertion (DOE). DOE is one of the earliest and most significant signs of progression.

Why the Other Options Are Incorrect:

A. Oxygen saturation of 92%

A slightly decreased O₂ saturation is not a primary indicator of progression. It can occur due to other factors, and more severe mitral stenosis would lead to lower oxygen levels with worsening pulmonary congestion.

C. Muted systolic murmur

Mitral stenosis produces a diastolic murmur, not a systolic murmur. Additionally, as stenosis progresses, the murmur often becomes louder, not muted.

D. Upper extremity weakness

Weakness in the upper extremities is not a classic symptom of mitral stenosis progression. It would be more concerning for neurological issues (e.g., stroke, embolism) rather than valve disease itself.
