A client who is receiving radiation treatment for laryngeal cancer has developed xerostomia and mucositis.

The nurse determines the client has an imbalanced nutritional intake and is consuming less than body requirements.

Which factor is the most likely cause for this problem?

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:

Impaired physical mobility relative to muscle rigidity has the highest priority in the nursing care plan for a client diagnosed with Parkinson's disease. Parkinson's disease is characterized by motor symptoms such as muscle rigidity, bradykinesia, and postural instability. Impaired physical mobility can significantly impact a patient's ability to perform activities of daily living and maintain independence. Addressing this issue is crucial to enhance the patient's quality of life and prevent complications such as falls.

Choice B rationale:

While the risk for aspiration relative to muscle weakness is a valid concern in Parkinson's disease, impaired physical mobility takes precedence as it directly affects the patient's ability to move, ambulate, and perform daily activities. Addressing mobility issues is fundamental to maintaining overall functioning and independence.

Choice C rationale:

The risk for constipation relative to immobility is important to address, but it is not the highest priority. Impaired physical mobility can lead to multiple complications, including constipation. However, improving mobility should be the primary focus to prevent a wide range of issues associated with Parkinson's disease.

Choice D rationale:

Self-care deficit relative to motor disturbance is a concern in Parkinson's disease, but it is not the highest priority. Impaired physical mobility directly impacts a patient's ability to engage in self-care activities. By addressing mobility issues first, the nurse can facilitate the patient's ability to perform self-care tasks more independently in the long run.
