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 ["B","C","D","E"]

Explanation

A. Take the medication with milk to increase absorption:

This statement is incorrect. Taking ferrous sulfate with milk or dairy products is not recommended as they can decrease iron absorption. It's advisable to take iron supplements with water or juice, preferably on an empty stomach or with a small amount of food.

B. Take the medication on an empty stomach:

This statement is partially correct. While taking ferrous sulfate on an empty stomach can enhance absorption, some individuals may experience gastrointestinal discomfort or irritation. Therefore, it's often recommended to take iron supplements with a small amount of food to minimize potential side effects.

C. Eat foods high in fiber while on this medication:

This statement is generally correct. Consuming foods high in fiber can help prevent constipation, which is a common side effect of iron supplements. Including fiber-rich foods in the diet, such as fruits, vegetables, whole grains, and legumes, can promote regular bowel movements.

D. Report stools that are dark in color immediately:

This statement is correct. Dark or black stools can indicate the presence of digested blood, which may occur due to iron supplementation. It's important to report such changes to the healthcare provider promptly for further evaluation.

E. Eating citrus fruit and juices are recommended with meals:

This statement is correct. Citrus fruits and juices, such as oranges, grapefruits, and lemon juice, contain vitamin C, which can enhance iron absorption. Consuming vitamin C-rich foods or drinks along with iron supplements can help improve iron uptake by the body.

A. 120/80 mm Hg or lower. B. Average of two BP readings of 150/80 mm Hg C. 140/90 mm Hg or lower D. 156/96 mm Hg or lower

Correct Answer is C

Explanation

A. 120/80 mm Hg or lower:

This blood pressure range is considered normal or optimal for most adults. However, for individuals diagnosed with hypertension, the goal is typically to reduce blood pressure to below 140/90 mm Hg, as maintaining normal blood pressure is not considered a goal for hypertension treatment unless specifically indicated based on individual circumstances.

B. Average of two BP readings of 150/80 mm Hg:

A blood pressure reading of 150/80 mm Hg is elevated and indicates hypertension, especially if consistently elevated across multiple readings. The goal of hypertension treatment is to lower blood pressure to below 140/90 mm Hg, so an average of 150/80 mm Hg would not be considered the goal of treatment.

C. 140/90 mm Hg or lower:

This blood pressure range is commonly recommended as the goal of treatment for individuals with hypertension who otherwise enjoy good health. It represents a balance between effective blood pressure control and minimizing the risk of side effects or complications associated with overly aggressive treatment.

D. 156/96 mm Hg or lower:

While a blood pressure reading of 156/96 mm Hg is elevated and indicates hypertension, the goal of treatment is typically to reduce blood pressure to below 140/90 mm Hg rather than targeting a specific numeric value below 156/96 mm Hg.
