The nurse receives a client from the post-anesthesia unit with a new onset of sinus tachycardia and a heart rate of 118 beats per minute. To which reasons does the nurse relate the increased heart rate? (Select All that Apply.)

Anxiety

Sleep

Fever

Hyperglycemia

Blood loss

Answer and Explanation

Correct Answer : A,C,E

A. Anxiety:

Anxiety can lead to an increased heart rate due to the activation of the sympathetic nervous system. When a person is anxious, their body releases stress hormones like adrenaline, which can stimulate the heart to beat faster. This increased sympathetic activity can cause sinus tachycardia, where the heart rate is faster than normal.

B. Sleep:

While sleep can affect heart rate variability, causing fluctuations in heart rate during different stages of sleep, it typically does not cause a significant and sustained increase in heart rate like sinus tachycardia. Sleep is more likely to influence heart rate patterns rather than directly cause sinus tachycardia.

C. Fever:

Fever, especially in response to infection or inflammation, can lead to an elevated heart rate. The body's response to fever includes increased metabolic activity, which can raise the heart rate as part of the physiological stress response. Fever-induced sinus tachycardia is a common finding in individuals with infections.

D. Hyperglycemia:

While hyperglycemia (high blood sugar levels) can have cardiovascular effects over time, such as contributing to atherosclerosis and heart disease, it is not typically a direct cause of sinus tachycardia. Sinus tachycardia is more commonly associated with acute stressors like anxiety, fever, or hypovolemia (such as from blood loss).

E. Blood loss:

Significant blood loss, such as during surgery or due to trauma, can result in hypovolemia, where there is a decrease in blood volume circulating in the body. In response to hypovolemia, compensatory mechanisms kick in, including an increase in heart rate (sinus tachycardia), to maintain blood pressure and perfusion to vital organs.

Correct Answer is D

Explanation

A. Furosemide 10mg IV bolus every 12 hours:

Furosemide is a loop diuretic commonly used in heart failure management to reduce fluid overload. The prescribed dose of 10 mg IV bolus every 12 hours is within the typical range for furosemide administration in acute heart failure.

B. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain:

Morphine sulfate is often used in the management of acute pain, including pain associated with myocardial infarction. The prescribed dose of 2 mg IV bolus every 2 hours PRN for pain is appropriate and aligns with standard pain management protocols.

C. Laboratory testing of serum potassium upon admission:

It is common practice to perform laboratory testing, including serum potassium levels, upon admission for clients with acute heart failure, especially if they are receiving diuretics or other medications that can affect electrolyte balance. This prescription is appropriate and necessary for monitoring the client's condition.

D. 0.9% normal saline IV at 150 mL/hr continuous:

This prescription raises a concern because administering 0.9% normal saline at a rate of 150 mL/hr continuously may lead to fluid overload in a client with acute heart failure. The rate of IV fluid administration should be carefully assessed based on the client's fluid status, renal function, and hemodynamic parameters to avoid exacerbating heart failure symptoms.

A. numbness in extremities B. fatigue C. Shortness of breath D. anorexia E. Chest pain F. Confusion

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

Explanation

A. Numbness in extremities: Numbness in extremities is not a common adverse effect of digoxin. The focus of digoxin monitoring is primarily on cardiovascular and gastrointestinal effects.

B. Fatigue: Fatigue is a common adverse effect of digoxin and can indicate toxicity or overdose. Clients taking digoxin should be monitored for increased fatigue or weakness.

C. Shortness of breath: Shortness of breath can occur as an adverse effect of digoxin toxicity, particularly if it leads to pulmonary congestion or heart failure exacerbation.

D. Anorexia: Anorexia, or loss of appetite, can be a gastrointestinal adverse effect of digoxin. Clients may experience nausea, vomiting, or anorexia, which can contribute to weight loss and electrolyte imbalances.

E. Chest pain: Chest pain can be a sign of digoxin toxicity, especially if it is associated with other symptoms such as shortness of breath or palpitations. It is essential to evaluate any chest pain in a client taking digoxin.

F. Confusion: Confusion or changes in mental status can occur with digoxin toxicity, particularly in older adults. Clients should be monitored for signs of confusion, delirium, or other cognitive changes.
