A nurse is reinforcing teaching with a client who is scheduled to have a colonoscopy in 1 week. Which of the following client statements indicates an understanding of the teaching?

Rationale:

A. Administer haloperidol via the intramuscular route: Medication may be necessary for agitation, but administering it before assessing the client’s emotional state and safety is premature and could escalate distress.

B. Collect data regarding the client’s feelings: Assessing the client’s emotional state and reasons for pacing and clenched fists helps identify triggers, enabling the nurse to choose the least restrictive intervention and promote de-escalation.

C. Obtain assistance to apply wrist restraints: Restraints are a last resort to ensure safety and should only be used after less restrictive interventions have failed and when the client poses an immediate risk to self or others.

D. Move the client into the seclusion room: Seclusion is also a restrictive intervention requiring assessment of necessity. Moving the client without first gathering data and attempting de-escalation may violate client rights and worsen agitation.

Rationale:

A. Nifedipine: Nifedipine is a calcium channel blocker that helps reduce myocardial oxygen demand by decreasing afterload and dilating coronary arteries. However, it is not the priority in acute chest pain management because it has a slower onset compared to nitroglycerin.

B. Nitroglycerin: Nitroglycerin is the priority medication for acute angina. It works rapidly by dilating coronary arteries and reducing myocardial oxygen demand, which helps relieve chest pressure and prevent progression to myocardial infarction.

C. Atenolol: Atenolol, a beta-blocker, decreases heart rate and contractility to reduce myocardial oxygen consumption. While useful for long-term angina management, it is not the first-line agent for immediate chest pain relief in acute settings.

D. Clopidogrel: Clopidogrel is an antiplatelet agent that prevents clot formation, often used in long-term management or following stent placement. It does not provide immediate relief from angina and is therefore not the priority medication in this scenario.
