While a nurse is caring for a client who is receiving mechanical ventilation via an endotracheal tube, the high-pressure alarm on the ventilator sounds.
Which of the following actions should the nurse take?
Tighten the tubing connections.
Request insertion of a tracheostomy tube.
Suction the client's airway.
Look for a leak in the tube's cuff.
The Correct Answer is C
Choice A rationale:
Tightening the tubing connections may be necessary if there is a leak in the ventilator system, but it does not address the high-pressure alarm issue. The nurse needs to address the immediate alarm situation first.
Choice B rationale:
Requesting insertion of a tracheostomy tube is not the appropriate action for a high-pressure alarm on the ventilator. Tracheostomy tube insertion is a significant procedure that is not indicated solely based on a high-pressure alarm.
Choice C rationale:
Suctioning the client's airway is the correct action for a high-pressure alarm on the ventilator. The alarm indicates an obstruction in the airway, and suctioning can help clear any secretions or blockages, allowing the client to breathe more effectively.
Choice D rationale:
Looking for a leak in the tube's cuff may be necessary if the high-pressure alarm persists after suctioning and checking connections. Identifying and repairing any leaks can prevent further issues with ventilation. However, immediate action should be taken to clear the airway first, as indicated by suctioning.

Correct Answer is B
Explanation
- A. Incorrect. Withholding pain medications for 24 hr after the old patch is removed is a harmful action that could cause severe withdrawal symptoms and uncontrolled pain for the client. The nurse should respect the client's right to refuse treatment and explore the reasons for their decision.
- B. Correct. Asking another nurse to witness the disposal of the new patch is a safe and legal action that follows the policies and procedures for handling controlled substances. The nurse should document the disposal of the new patch and report it to the appropriate authority.
- C. Incorrect. Sealing the patches in a plastic bag and placing them in the client's trash basket is an unsafe and illegal action that could lead to diversion, misuse, or accidental exposure of fentanyl to others. The nurse should dispose of the patches in a secure and designated container that prevents access by unauthorized persons.
- D. Incorrect. Sticking the two patches to each other and placing them in the sharps bin is an unsafe and improper action that could cause contamination, injury, or infection to others who handle or dispose of sharps waste. The nurse should dispose of the patches separately and carefully, avoiding contact with their adhesive surfaces.
Correct Answer is A
Explanation
a. Improves muscle strength.
Explanation:
Neostigmine is a medication used in the treatment of myasthenia gravis (MG). It belongs to a class of drugs called cholinesterase inhibitors. Neostigmine works by inhibiting the breakdown of acetylcholine, a neurotransmiter involved in muscle contraction. In MG, there is a decrease in the amount of acetylcholine available at the neuromuscular junction, leading to muscle weakness and fatigue.
By inhibiting the breakdown of acetylcholine, neostigmine helps to increase the concentration of acetylcholine at the neuromuscular junction. This, in turn, improves muscle strength and can alleviate the symptoms of weakness and fatigue associated with MG.
Option b, destroying the antibodies that cause MG, is not accurate. Myasthenia gravis is an autoimmune disorder characterized by the presence of antibodies that interfere with neuromuscular transmission.
Neostigmine does not directly target or eliminate these antibodies.
Option c, enhancing immune system function, is not accurate either. Neostigmine primarily acts on the neuromuscular junction to improve muscle strength and does not have a direct effect on immune system function.
Option d, preventing excessive coughing, is not the primary action of neostigmine. While increased muscle strength may indirectly improve respiratory function and reduce coughing in individuals with myasthenia gravis, it is not the primary indication or action of neostigmine.
Therefore, the most accurate information to include in teaching about neostigmine for a client with myasthenia gravis is that it improves muscle strength.
