A nurse explains to a client's family that the client's respirations are faster and deeper than normal because of what?
The client is expelling too much carbon dioxide.
The client's blood oxygen level indicates hypoxemia.
The client has developed an inflammation of the phrenic nerve.
The client is using his intercostal muscles to breathe.
The Correct Answer is C
Choice A rationale:
Pulse pressure is the difference between systolic and diastolic blood pressure and is not related to changing positions or the symptoms described in the scenario.
Choice B rationale:
Essential hypertension is a chronic medical condition characterized by elevated blood pressure levels persistently exceeding 140/90 mmHg. It is not directly related to positional changes or postural hypotension symptoms.
Choice C rationale:
Postural (orthostatic) hypotension occurs when a person experiences a sudden drop in blood pressure upon standing up from a sitting or lying position. This drop in blood pressure can lead to symptoms such as dizziness, lightheadedness, and fainting. Slowly changing positions is essential in managing postural hypotension because abrupt movements can worsen these symptoms. Educating the client about the importance of gradual position changes is crucial in preventing or minimizing postural hypotension-related symptoms.
Choice D rationale:
Pre-hypertension refers to blood pressure levels that are higher than normal but not high enough to be diagnosed as hypertension. It does not directly relate to the symptoms described in the scenario.

Correct Answer is ["2"]
Explanation
Diazepam is prescribed in a 10 mg dose, and the concentration of diazepam in the injection is 5 mg per mL. By dividing the prescribed dose (10 mg) by the concentration of the drug in the injection (5 mg/mL), the result is 2 mL. This is the correct administration dose.
Correct Answer is C
Explanation
Choice A rationale:
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.
Choice B rationale:
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.
Choice C rationale:
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.
Choice D rationale:
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. .
