A postoperative patient has an order for Kefzol 1g in 25 mL of D5W over 15 minutes. The medication will be infused with an IV pump. How many milliliters per hour should the IV pump be programmed for?

Answer and Explanation

The Correct Answer is ["100"]

Total volume to be infused = 25 mL.

Infusion time in minutes = 15 minutes.

Convert the infusion time from minutes to hours.

Infusion time in hours = 15 minutes / 60 minutes/hour

= 0.25 hours.

Calculate the infusion rate in milliliters per hour (mL/hr).

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)

= 25 mL / 0.25 hr

= 100 mL/hr.

Correct Answer is C

Explanation

A. Dysphagia: While difficulty swallowing (dysphagia) can occur as a result of laryngeal cancer, it is not typically one of the earliest manifestations. It usually occurs when the tumor progresses and obstructs the swallowing mechanism.

B. Weight loss: Weight loss can be a later sign of cancer or a result of difficulty eating, but it is not typically the earliest manifestation of laryngeal cancer.

C. Hoarseness: Hoarseness or a persistent change in voice is the earliest and most common symptom of laryngeal cancer, especially in individuals with a history of smoking. It occurs because the cancer affects the vocal cords, leading to voice changes.

D. Dyspnea: Difficulty breathing (dyspnea) can occur later in the disease if the tumor obstructs the airway, but it is not typically an early sign of laryngeal cancer.

A. Deep respirations B. Clubbing of the fingers C. Barrel chest D. Bradycardia E. Dyspnea

Correct Answer is ["B","C","E"]

Explanation

A. Deep respirations: Clients with emphysema typically exhibit shallow, rapid breathing rather than deep respirations. This is due to the compromised lung function and air trapping in the alveoli, which causes them to use more effort in breathing.

B. Clubbing of the fingers: Clubbing of the fingers is a common finding in chronic lung diseases like emphysema. It is a result of prolonged hypoxia and occurs due to changes in the nails and soft tissues of the fingers and toes.

C. Barrel chest: A barrel chest is a classic finding in emphysema, caused by the lungs hyperinflating and causing the rib cage to remain in an expanded position. This occurs due to the trapping of air in the lungs, leading to increased anterior-posterior chest diameter.

D. Bradycardia: Bradycardia is not typically associated with emphysema. Patients with emphysema often experience tachycardia (increased heart rate) as a compensatory mechanism for low oxygen levels.

E. Dyspnea: Dyspnea is a hallmark symptom of emphysema. As the disease progresses, clients often experience increasing difficulty in breathing, especially during exertion. This results from the destruction of the alveoli and the loss of surface area for gas exchange.
