NurseDive Free Nursing Practice Question
The nurse identifies this condition as what?
A. Tachypnea.
Diastolic pressure represents the pressure in the arteries when the heart is at rest between contractions. It specifically measures the force of blood against the arterial walls when both the atria and ventricles are relaxed, allowing the heart to fill with blood. Diastolic pressure is the bottom number in a blood pressure reading (e.g., 120/80 mmHg), indicating the pressure in the arteries during the heart's resting phase. Elevated diastolic pressure is an important indicator of increased risk for cardiovascular diseases, such as hypertension.
B. Apnea.
This statement describes systolic blood pressure, which measures the pressure in the arteries when the heart's ventricles contract and pump blood into the circulation. Systolic pressure is the top number in a blood pressure reading (e.g., 120/80 mmHg) and represents the highest pressure reached in the arteries during a cardiac cycle.
C. Bradypnea.
This description is not accurate for either diastolic or systolic pressure. Both atria and ventricles do not contract simultaneously; they follow a specific sequence to ensure effective pumping of blood through the heart.
D. Eupnea.
This statement is incorrect as it does not align with the definitions of diastolic or systolic blood pressure. Diastolic pressure specifically measures the pressure in the arteries during the heart's resting phase, not when the ventricles relax. .

Full Explanation
Choice A rationale:

Diastolic pressure is the bottom number in a blood pressure reading (e.g., 120/80 mmHg), indicating the pressure in the arteries during the heart's resting phase. Elevated diastolic pressure is an important indicator of increased risk for cardiovascular diseases, such as hypertension.
Choice B rationale:
This statement describes systolic blood pressure, which measures the pressure in the arteries when the heart's ventricles contract and pump blood into the circulation. Systolic pressure is the top number in a blood pressure reading (e.g., 120/80 mmHg) and represents the highest pressure reached in the arteries during a cardiac cycle.
Choice C rationale:
This description is not accurate for either diastolic or systolic pressure. Both atria and ventricles do not contract simultaneously; they follow a specific sequence to ensure effective pumping of blood through the heart.

Similar Questions
A nurse is assessing peripheral pulses on a client and is aware that which action is a safety issue when assessing the client's peripheral pulses?
A. Counting a regular pulse for 30 seconds and doubling the number to obtain the rate.
The client's respirations are faster and deeper than normal due to expelling too much carbon dioxide. This condition is known as hyperventilation. Hyperventilation can occur due to various reasons such as anxiety, pain, fever, or metabolic acidosis. When the body expels excessive carbon dioxide, it leads to respiratory alkalosis, resulting in faster and deeper breathing to compensate for the decrease in carbon dioxide levels in the blood.
B. Palpates the femoral artery in the groin of the client.
This option is incorrect. Hypoxemia, or low blood oxygen levels, typically leads to rapid, shallow breathing (tachypnea) rather than deep and fast respirations.
C. Palpates both carotid pulses at the same time.
This option is incorrect. Inflammation of the phrenic nerve does not directly affect the depth and rate of respirations. Phrenic nerve inflammation is more likely to cause pain during breathing or hiccups.
D. Palpates the radial artery on the thumb side of the wrist.
This option is incorrect. Using intercostal muscles to breathe is a normal physiological process, especially during deep or labored breathing. However, it does not explain the specific situation described in the question, where the respirations are faster and deeper than normal.

To accurately take a client's blood pressure, which action by the nurse is most important?
A. Obtain the blood pressure first thing in the morning.
This option is incorrect. Tachypnea refers to abnormally fast breathing, typically defined as a respiratory rate higher than 20 breaths per minute in adults. It is the opposite of the condition described in the question, where the respiratory rate has fallen below 10 respirations per minute.
B. Use the appropriate size cuff for the client.
This option is incorrect. Apnea refers to the absence of breathing, often resulting from a temporary cessation of airflow to the lungs. It is characterized by the complete absence of respiratory movements and sounds, which is different from the situation described in the question where the client is breathing at a very slow rate.
C. Make sure the client is relaxed and comfortable prior to obtaining the blood pressure.
Bradypnea, or abnormally slow breathing, is the correct answer in this case. It is defined as a respiratory rate lower than the normal range, which is typically between 12 to 20 breaths per minute in adults. Bradypnea can be caused by various factors, including drug overdose, neurological disorders, or metabolic imbalances. In this scenario, the client's slow respiratory rate (below 10 respirations per minute) indicates bradypnea.
D. Remove the clothing from arms before obtaining the blood pressure.
This option is incorrect. Eupnea refers to normal breathing, where the rate and depth of respirations are within the normal range. It does not describe the condition of the sedated client in the question, who is experiencing abnormally slow breathing (bradypnea)

The nurse is assessing the client's vital signs and is aware that which assessment data requires immediate attention?
A. An oral temperature of 100°F (37.8°C)
This option is incorrect. Counting a regular pulse for 30 seconds and doubling the number is an appropriate method for assessing heart rate, not peripheral pulses. When assessing peripheral pulses, it is important to count the pulses directly for a full minute to accurately determine the pulse rate. This ensures that any irregularities or variations in the pulse rate are captured.
B. A respiratory rate of 30/min.
This option is incorrect. Palpating the femoral artery in the groin is a standard method for assessing peripheral pulses. It is not a safety issue when performed correctly. However, the question asks about a safety issue related to assessing peripheral pulses.
C. A radial pulse of 45 beats in 30 seconds.
Palpating both carotid pulses at the same time is a safety issue when assessing peripheral pulses. Simultaneously palpating both carotid pulses can lead to excessive pressure on the carotid sinuses, which are baroreceptors located in the carotid arteries. Stimulation of these baroreceptors can result in a reflex decrease in heart rate and blood pressure, leading to a condition known as carotid sinus hypersensitivity. This can cause dizziness, fainting, or, in extreme cases, cardiac arrest. Therefore, it is essential to avoid palpating both carotid pulses simultaneously to prevent adverse reactions in clients, especially those with cardiovascular issues.
D. A blood pressure of 114/74 mmHg.
Palpating the radial artery on the thumb side of the wrist is a standard method for assessing peripheral pulses. It is a safe and commonly used technique for evaluating radial pulse rate, rhythm, and amplitude. .
