A patient is on the ventilator and a high-pressure alarm sounds. The nurse should assess for which of these possible causes for the alarm?

The patient may need suctioning

The patient extubated himself

The ventilator tubing may be disconnected.

The cuff at the end of the endotracheal tube is deflated.

Answer and Explanation

The Correct Answer is A

A. The patient may need suctioning:
A high-pressure alarm indicates increased resistance to airflow, which could be caused by secretions or mucus in the airways. Suctioning is the appropriate intervention to clear the airways of excess secretions, reducing airway resistance and preventing the high-pressure alarm.

B. The patient extubated himself:
If the patient extubates himself (removes the endotracheal tube), this may result in a low-pressure alarm, not a high-pressure alarm. The low-pressure alarm is triggered when there is a loss of pressure within the ventilator circuit due to disconnection or extubation.

C. The ventilator tubing may be disconnected:
If the ventilator tubing is disconnected, it is more likely to trigger a low-pressure alarm, indicating a loss of pressure in the ventilator circuit. This is not the primary cause of increased resistance seen with a high-pressure alarm.

D. The cuff at the end of the endotracheal tube is deflated:
A deflated cuff can lead to air leakage around the endotracheal tube but is not the primary cause of increased airway resistance seen with a high-pressure alarm. It may cause a low-pressure alarm if cuff pressure is monitored.

Correct Answer is C

Explanation

A. Discomfort at the puncture site:
Some discomfort at the puncture site is normal after a thoracentesis. It may be managed with pain medication as needed.

B. Serosanguineous drainage from the puncture site:
Serosanguineous drainage (a mix of clear and bloody fluid) is a common and expected finding after a thoracentesis. It is part of the normal post-procedure care.

C. Increased heart rate
Increased heart rate can be indicative of a complication following a thoracentesis, such as a pneumothorax or bleeding. This requires immediate attention, and the healthcare provider should be contacted promptly for further evaluation and intervention.

D. Decreased temperature:
A decreased temperature alone is not typically associated with complications following a thoracentesis. It may be related to other factors, but it is not an immediate concern compared to an increased heart rate.

A. A client who was administered acyclovir for cellulitis reports pain in the affected leg B. A client who was administered adalimumab for Crohn’s disease, has a serum calcium level of 10 mg/dL, and reports a headache C. A client who was administered erythromycin for acute glomerulonephritis and reports reddish brown urinary output D. A client who was administered glipizide for type 2 diabetes mellitus and has a blood glucose of 68 mg/dl

Correct Answer is D

Explanation

A. Pain in the affected leg could indicate worsening of cellulitis or a potential complication like deep vein thrombosis (DVT), but there is no immediate indication of a life-threatening condition. This client should be assessed, but may not be the top priority unless other signs of complications are present.

B. A serum calcium level of 10 mg/dL is within the normal range (8.5 to 10.5 mg/dL). A headache, while concerning, is not immediately life-threatening unless there are additional symptoms suggesting something more severe.

C.Reddish brown urine suggests hematuria, a symptom of glomerulonephritis. This could indicate ongoing kidney issues, but unless there are signs of severe kidney failure or systemic infection, this might not be the most urgent case.

D. A blood glucose level of 68 mg/dL is low and can lead to hypoglycemia, which can be immediately life-threatening if it progresses to severe hypoglycemia. Symptoms of hypoglycemia include confusion, dizziness, sweating, and can escalate to seizures or unconsciousness if not promptly treated.
