ATI NUR 135 Exam 1 NSG

Correct Answer: D. The client has peripheral edema of both legs.

Explanation 

Refeeding syndrome occurs when a person who has been in a state of prolonged malnutrition is given nutritional support, particularly carbohydrates, too quickly. This leads to electrolyte imbalances and fluid shifts, which can cause complications such as peripheral edema, cardiac issues, muscle weakness, and respiratory distress. The peripheral edema is indicative of fluid retention and electrolyte imbalance, which are hallmark signs of refeeding syndrome.

Why the Other Options Are Incorrect:

A. The client had a weight gain of 0.91 kg (2 lb) over 1 week.

This weight gain is a normal part of the recovery process and does not necessarily indicate refeeding syndrome. Weight gain is expected in clients with anorexia nervosa as they begin to stabilize their nutritional intake, but it does not specifically suggest refeeding syndrome unless accompanied by signs of fluid retention or electrolyte imbalances.

B. The client reports increased appetite at bedtime.

Increased appetite is a positive sign of recovery and re-nourishment, especially after prolonged starvation. It does not suggest refeeding syndrome, but rather indicates that the body is starting to demand more food as it begins to recover. However, this by itself is not a warning sign of refeeding syndrome.

C. The client reports a sudden increased energy level.

A sudden increase in energy can be a positive sign that the client is responding well to nutritional support and is starting to feel better after prolonged malnutrition. This is not a characteristic of refeeding syndrome but is rather part of the body's initial recovery phase.

Summary:

The peripheral edema is a key indicator of refeeding syndrome in clients with anorexia nervosa who have recently started nutritional rehabilitation. This syndrome occurs due to fluid and electrolyte imbalances as the body adjusts to receiving nourishment after a period of starvation. The nurse should closely monitor for signs of electrolyte imbalances, particularly phosphate deficiency, and intervene appropriately to prevent further complications.

The correct answers are: 

"Muscular tension, blood pressure, and triglycerides increase."

"Immune system functioning decreases, and risk of cancer increases."

"Risk of depression, autoimmune disorders, and heart disease increases."

Explanation:

Long-term stress triggers prolonged activation of the body's sympathetic nervous system and hypothalamic-pituitary-adrenal (HPA) axis, leading to various negative physiological effects.

"Muscular tension, blood pressure, and triglycerides increase."

Chronic stress leads to persistent muscle tension, hypertension, and elevated triglycerides, increasing the risk of cardiovascular disease.

"Immune system functioning decreases, and risk of cancer increases."

Long-term stress suppresses the immune system, making the body more susceptible to illness, infections, and even cancer due to reduced immune surveillance.

"Risk of depression, autoimmune disorders, and heart disease increases."

Chronic stress contributes to mental health issues like depression and anxiety, triggers inflammatory responses linked to autoimmune disorders, and increases cardiovascular risk due to prolonged high blood pressure and lipid imbalances.

Incorrect Answers:

"Epinephrine is released, increasing heart and respiratory rates."

This response is associated with short-term (acute) stress, part of the "fight-or-flight" reaction, not long-term physiological effects.

"Corticosteroid release increases stamina and impedes digestion."

While corticosteroids (like cortisol) do impact digestion, increased stamina is a short-term effect. Over time, chronic cortisol elevation leads to fatigue, insulin resistance, and digestive issues rather than enhanced stamina.

"Cortisol is released, increasing glucogenesis and reducing fluid loss."

Cortisol does promote gluconeogenesis (glucose production), but fluid loss reduction is more of an acute response. Chronic stress can eventually contribute to fluid retention and metabolic imbalances.

Summary:

Long-term physiological responses to stress include increased blood pressure, muscle tension, and triglycerides, immune system suppression and cancer risk, and higher risks of depression, autoimmune disorders, and heart disease. Acute responses like epinephrine release and temporary stamina boosts do not persist long-term.

Correct Answer: C. Chest pain and shortness of breath

Explanation 

Chest pain and shortness of breath are classic physical manifestations of panic disorder. During a panic attack, the body experiences a fight-or-flight response, which can cause the chest to feel tight or painful and lead to difficulty breathing or shortness of breath (dyspnea). These symptoms mimic those of a heart attack, which can lead to significant distress and fear of dying. The intensity of these symptoms is a hallmark of panic attacks and is often what prompts individuals to seek emergency medical attention. It is also one of the most concerning symptoms, as patients often misinterpret it as a life-threatening event.

Why the Other Options Are Incorrect:

A. Dizziness and lightheadedness

Dizziness and lightheadedness can occur during a panic attack due to hyperventilation (rapid breathing), but they are not as central or defining to panic disorder as chest pain and shortness of breath.

B. Excessive sweating and increased heart rate

While excessive sweating and tachycardia (increased heart rate) are common in panic attacks, they are more generalized signs of sympathetic nervous system activation and are not as specifically associated with panic disorder as chest pain and shortness of breath.

D. Tremors and muscle tension

Tremors and muscle tension are also common symptoms of panic attacks, but they are less specific and may be seen in other anxiety-related disorders. These symptoms, while significant, are typically not the primary reason clients seek immediate medical care.

Summary:

Chest pain and shortness of breath are the most common and defining symptoms of panic disorder, and they often mimic life-threatening conditions like heart attacks, which makes them especially alarming for clients. This is why they are considered the hallmark manifestations of panic attacks.

The correct answer is: C) Prediabetes

Explanation:

A fasting glucose level of 7.2 mmol/L falls into the range of prediabetes according to the American Diabetes Association (ADA) guidelines. 

Normal fasting glucose: Below 5.6 mmol/L (100 mg/dL).

Prediabetes: Fasting glucose between 5.6 mmol/L (100 mg/dL) and 6.9 mmol/L (125 mg/dL).

Diabetes: Fasting glucose of 7.0 mmol/L (126 mg/dL) or higher.

Since 7.2 mmol/L is above the normal range and below the threshold for diabetes, it indicates prediabetes, a condition where blood glucose levels are elevated but not yet high enough to be classified as diabetes.

Why the other options are incorrect:

A) Normal glucose level: A fasting glucose of 7.2 mmol/L is elevated, so it's not a normal level.

B) Hypoglycemia: Hypoglycemia refers to low blood sugar levels, typically below 3.9 mmol/L (70 mg/dL).

D) Diabetic ketoacidosis (DKA): DKA usually occurs in patients with type 1 diabetes and is marked by very high blood glucose levels, typically greater than 13.9 mmol/L (250 mg/dL), accompanied by ketones in the urine and blood.

Summary:

A fasting glucose level of 7.2 mmol/L is classified as prediabetes, indicating that the person has an increased risk of developing type 2 diabetes.

The correct answer is: B. Aspirin and heparin

Explanation:

Unstable angina is a type of acute coronary syndrome (ACS) that requires immediate medical attention. The goal of treatment for unstable angina is to prevent the progression to a myocardial infarction (MI) and to manage the symptoms. Aspirin and heparin are commonly prescribed for the following reasons:

Aspirin: It is an antiplatelet medication that helps prevent the formation of blood clots by inhibiting the activity of platelets, reducing the risk of a thrombus (clot) forming in the coronary arteries, which can worsen the angina or lead to a heart attack.

Heparin: It is an anticoagulant that works to prevent the formation of clots, especially in patients with unstable angina who may have a partially obstructed coronary artery. Heparin reduces the likelihood of clot progression, which could lead to a complete blockage and myocardial infarction.

Why the Other Options Are Incorrect:

A. Beta-blockers: While beta-blockers are commonly used in stable angina and after a myocardial infarction to reduce the workload on the heart and lower heart rate, they are not the first-line treatment in unstable angina. In the acute phase, antiplatelet and anticoagulant therapy are prioritized.

C. Corticosteroids: Corticosteroids are not typically used to manage unstable angina. They are used to treat conditions involving inflammation, but they do not directly address the underlying mechanisms of unstable angina or acute coronary syndrome.

D. Proton pump inhibitors (PPIs): PPIs are used to treat gastric acid-related conditions (like GERD or ulcers) and do not address the underlying causes of unstable angina.

Key Takeaway:

For unstable angina, the primary treatment involves medications like aspirin and heparin, which help reduce the risk of clot formation and prevent progression to a heart attack.

The correct answer is A. Digoxin.

Explanation:

Digoxin is a cardiac glycoside that improves myocardial contractility by increasing calcium availability in the heart muscle. It inhibits the Na+/K+ ATPase pump, leading to an increase in intracellular sodium. This, in turn, affects the calcium-sodium exchange pump, increasing intracellular calcium, which enhances the contractility of the heart (positive inotropic effect). Digoxin is commonly used in heart failure to improve the efficiency of the heart's pumping action.

Why the other options are incorrect:

B. Furosemide: Furosemide is a loop diuretic used to manage fluid retention and edema in heart failure by promoting the excretion of sodium, chloride, and water through the kidneys. While it helps relieve symptoms like pulmonary edema, it does not affect myocardial contractility.

C. Metoprolol: Metoprolol is a beta-blocker that works by blocking beta-1 adrenergic receptors in the heart. It reduces heart rate, blood pressure, and myocardial oxygen demand, which can help manage heart failure. However, it does not increase myocardial contractility. In fact, it can reduce contractility to a degree as part of its mechanism.

D. Amlodipine: Amlodipine is a calcium channel blocker that relaxes and dilates blood vessels, reducing blood pressure and helping to relieve angina. While it affects calcium, it works by inhibiting calcium entry into smooth muscle cells, not by increasing calcium availability in the heart muscle to improve contractility.

Summary:

Digoxin is the correct medication that improves myocardial contractility by increasing calcium availability in heart muscle cells, making it effective in managing heart failure. The other medications listed (furosemide, metoprolol, and amlodipine) do not enhance myocardial contractility in the same way.

Correct Answer: d. Checking the patient's belongings for dangerous items

Explanation

The safety of the patient is the top priority, especially following a suicide attempt. Upon admission, the nurse must conduct a thorough search of the patient's belongings to ensure they do not have any items that could be used for self-harm, such as sharp objects, medications, or cords. This aligns with Maslow’s hierarchy of needs, where physiological safety comes before emotional needs like trust and communication.

Explanation of the Incorrect Options:

a. Allowing the patient to return to her previous room so that she will feel safe

While familiarity can provide comfort, ensuring a safe environment takes priority. The patient’s room must first be assessed for any potential risks before assigning them to it.

b. Orienting the patient to the unit and introducing her to patients and staff

 Orientation is important for adjustment and comfort, but it is not the first priority. Safety measures must be completed before introductions.

c. Building trust through therapeutic communication

 Establishing trust is essential for long-term care, but it cannot happen until the patient is physically safe. Checking for dangerous items must come first to prevent immediate harm.

Summary:

The first and most critical nursing intervention upon admission is checking the patient’s belongings for any dangerous items. Patient safety always takes precedence over orientation, room assignment, or therapeutic communication.

The correct answer is: "Set limits for the relationship."

Explanation:

Establishing clear boundaries is essential in developing a therapeutic nurse-client relationship. Setting limits helps maintain professionalism, trust, and a safe environment while ensuring the relationship remains focused on the client’s well-being and therapeutic goals. This prevents over-involvement, dependency, or inappropriate interactions.

Why the Other Options Are Incorrect:

"Engage in friendly interactions with the client."

While being warm and empathetic is important, a therapeutic relationship is different from a friendship. The nurse must maintain professional boundaries rather than engage in casual or overly friendly interactions.

"Instruct the client on how he should behave."

A therapeutic relationship is based on collaboration and support, not control. Instead of instructing the client on how to behave, the nurse should guide, encourage self-awareness, and empower the client to make their own decisions.

"Promote the use of transference by the client."

Transference occurs when a client unconsciously redirects emotions (e.g., seeing the nurse as a parental figure). While transference may naturally occur, the nurse should not encourage it because it can distort the therapeutic relationship and hinder progress. Instead, the nurse should help the client recognize and work through these feelings.

Summary:

The best action is to set limits for the relationship, as this helps maintain professionalism, trust, and a clear therapeutic focus. The other options either risk blurring professional boundaries, creating dependency, or exerting control over the client, which is not therapeutic.

The correct answer is:  C. Atherosclerotic plaque rupture leading to thrombus formation

Explanation:

The most common cause of myocardial infarction (MI) is the rupture of an atherosclerotic plaque, which triggers the formation of a thrombus (blood clot) that completely occludes a coronary artery. This blockage prevents oxygenated blood from reaching the myocardium, leading to ischemia and necrosis (heart muscle death).

Why the Other Options Are Incorrect:

A. Coronary artery spasm

Coronary artery spasms (as seen in Prinzmetal’s angina) can temporarily reduce blood flow, but they are not the primary cause of most MIs.

B. Viral infection

Viral infections can cause myocarditis (inflammation of the heart muscle), but they do not directly cause an MI due to arterial blockage.

D. Pulmonary embolism

A pulmonary embolism (PE) is a clot in the lungs, which can strain the right heart and cause cardiac arrest, but it does not directly cause an MI.

Key Takeaways:

Atherosclerosis → plaque rupture → thrombus formation → MI

Coronary spasms cause angina, not typical MIs

MIs result from blocked coronary arteries, not lung clots or infections
