A nurse is collecting data on a client who has bradycardia. Which of the following findings should the nurse expect?
Fixed volume deficit
Anxiety
Lightheadedness
Elevated temperature
The Correct Answer is C
Choice A reason : A fixed volume deficit, or hypovolemia, is not a direct finding associated with bradycardia. Bradycardia refers to a slower than normal heart rate, typically below 60 beats per minute in adults⁸. Hypovolemia can cause various compensatory mechanisms to activate, including an increase in heart rate to maintain cardiac output, which is the opposite of bradycardia. Therefore, a fixed volume deficit is not a typical finding in bradycardia unless it is part of a broader clinical picture⁹.
Choice B reason : Anxiety is a condition that can sometimes lead to an increased heart rate, known as tachycardia, rather than a decreased heart rate as seen in bradycardia. While anxiety can coexist with bradycardia, especially if the patient is anxious about their health, it is not a direct symptom or finding of bradycardia itself⁹.
Choice C reason : Lightheadedness is a common symptom of bradycardia. When the heart rate is too slow, it may lead to inadequate cerebral perfusion, which can cause a feeling of lightheadedness or dizziness. This symptom can be particularly evident when the patient changes positions, such as standing up quickly, which can exacerbate the effects of reduced cardiac output on cerebral blood flow⁸⁹.
Choice D reason : An elevated temperature is not typically associated with bradycardia. Fever can actually lead to an increased heart rate as the body attempts to manage the higher metabolic demands associated with a raised temperature. Bradycardia in the presence of fever might indicate a more complex clinical scenario, such as myocarditis or central nervous system infections, but it is not a direct finding of bradycardia⁹.

Correct Answer is C
Explanation
Choice A reason : Setting a goal body weight within 25% of the ideal body weight can be misleading. The ideal body weight should be determined based on body mass index (BMI), considering the individual's height and weight. A BMI of 18.5 to 24.9 is considered normal.
Choice B reason : This is a general guideline for alcohol consumption, but for individuals with hypertension, it is often recommended to limit alcohol intake even further to help manage blood pressure
Choice C reason : This is a key recommendation for managing hypertension. Reducing sodium intake helps lower blood pressure and is a widely accepted guideline
Choice D reason : Monitoring potassium levels is crucial when taking thiazide diuretics because these medications can decrease potassium levels in the blood, leading to hypokalemia.
Correct Answer is ["50"]
Explanation
Step 1 is to calculate the total drops (gtt) the nurse needs to administer. This is done by multiplying the volume of the solution (400 mL) by the drop factor (60 gtt/mL). So, 400 mL × 60 gtt/mL = 24000 gtt.
Step 2 is to calculate the total time in minutes over which the IV should be administered. Since there are 60 minutes in an hour, 8 hours is equivalent to 8 hours × 60 min/hour = 480 minutes.
Step 3 is to calculate the rate at which the IV should be administered. This is done by dividing the total drops by the total time. So, 24000 gtt ÷ 480 min = 50 gtt/min.
The nurse should set the manual IV infusion to deliver approximately 50 gtt/min.
