. A nurse is preparing to administer 0.9% sodium chloride 1 L IV to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["31"]
Desired volume: 1 L = 1,000 mL
Infusion time: 8 hours = 480 minutes
Drop factor: 15 gtts/mL
Formula: (Volume (mL) ÷ Time (min)) × Drop factor (gtts/mL)
= (1000 ÷ 480) × 15
= 31.25
Rounded to the nearest whole number: 31 gtt/min

Correct Answer is C
Explanation
A. PR interval: The PR interval represents the time from the onset of atrial depolarization to the onset of ventricular depolarization, not the duration of ventricular depolarization.
B. ST segment: The ST segment represents the period between ventricular depolarization and repolarization. It does not indicate the time of depolarization.
C. QRS complex: The QRS complex represents ventricular depolarization, which is the electrical activity that causes the ventricles to contract.
D. QT interval: The QT interval represents the time it takes for both ventricular depolarization and repolarization, not just depolarization.
Correct Answer is []
Explanation
Condition:
Left-sided heart failure: The client is presenting with classic symptoms of left-sided heart failure, such as fatigue, weakness, nocturia (awakening at night to urinate), crackles in the lungs (due to fluid accumulation), a rapid and irregular apical heart rate, an audible S3 gallop, and a dry, hacking cough. These are indicative of pulmonary congestion, which is typical in left-sided heart failure.
Actions to take:
- Administer supplemental oxygen: Since the client is experiencing pulmonary congestion with crackles and a rapid irregular heart rate, supplemental oxygen will help to improve oxygenation and alleviate dyspnea associated with heart failure.
- Elevate the head of the client’s bed: Elevating the head of the bed will promote better lung expansion, reduce pulmonary congestion, and ease breathing, which is beneficial in managing the symptoms of left-sided heart failure.
Parameters to monitor:
- Urine output: Monitoring urine output helps assess the effectiveness of diuretic therapy and overall kidney function. In heart failure, decreased perfusion to the kidneys may lead to fluid retention, so monitoring urine output is essential in evaluating fluid balance.
- Weight: Daily weight monitoring is important in heart failure management to detect fluid retention. A rapid weight gain may indicate worsening heart failure, while a reduction in weight could signify successful diuresis and fluid management.
