A male client who is admitted with bipolar disorder, manic psychosis, is placed in seclusion after unsuccessful attempts to de-escalate him during a sudden mood swing from laughter to jumping and screaming threats while waving a plastic dinner knife.

The client is given haloperidol.

5 mg intramuscularly STAT prior to seclusion.

Which intervention is most important for the nurse to implement immediately after seclusion?

Choice A rationale:

Verapamil is a calcium channel blocker and is expected to decrease heart rate by inhibiting calcium influx into cardiac cells, particularly in the SA (sinoatrial) node, where it can slow down the heart's electrical impulses.

Choice B rationale:

Increased contractility is not an expected outcome of verapamil use. In fact, verapamil's main action is to decrease myocardial contractility, making it useful for treating conditions like angina and atrial fibrillation.

Choice C rationale:

Verapamil is known to dilate coronary arteries, which can improve blood flow to the heart muscle and relieve symptoms of angina.

Choice D rationale:

Reduced blood pressure is an expected outcome of verapamil use due to its vasodilatory effects on peripheral blood vessels. This can be beneficial in treating hypertension and angina.

Choice E rationale:

Relieved chest pain is an expected outcome of verapamil use, particularly in the case of variant angina (Prinzmetal's angina), as it helps to relax coronary arteries and reduce coronary artery spasm, which is a common cause of chest pain in this condition.

Choice A rationale:

"Phobias are characterized by persistent and irrational fear" (Choice A) is an accurate statement. Phobias are defined by the presence of an intense and irrational fear of a specific object or situation. This fear is persistent and often leads to avoidance behaviors, which can significantly impact the individual's daily life.

Choice B rationale:

"Phobias can be caused by biological factors only" (Choice B) is an inaccurate statement. Phobias can have various causes, including both biological and psychological factors. While there may be genetic predispositions to certain phobias, psychological factors, such as traumatic experiences or learned behaviors, can also contribute to the development of phobias.

Choice C rationale:

"Phobias can be diagnosed based on physical symptoms" (Choice C) is an inaccurate statement. Phobias are typically diagnosed based on the individual's reported symptoms, such as intense fear and avoidance behaviors. There are no specific physical symptoms that directly indicate the presence of a phobia.

Choice D rationale:

"Phobias can be managed with medication alone" (Choice D) is an inaccurate statement. Medication alone is not considered the primary treatment for phobias. While medications like selective serotonin reuptake inhibitors (SSRIs) or benzodiazepines may be prescribed to alleviate anxiety symptoms, the most effective treatment for phobias is psychotherapy, particularly exposure therapy or cognitive-behavioral therapy. These therapies address the root causes of the phobia and help individuals learn to manage their fear.
