The nurse is caring for a patient waiting for proper diagnosis with Multiple Sclerosis (MS) or Myasthenia Gravis (MG). The patient is reporting severe fatigue. Which priority intervention would the nurse implement to address this issue for either diagnosis?

A. Atenolol is a beta-blocker, which can lower heart rate and blood pressure. A heart rate of 52 and a blood pressure of 90/56 are both abnormally low. The nurse should hold the medication and contact the provider, as this could indicate bradycardia or hypotension, both of which can be dangerous.

B. Recent intake of sildenafil. Sildenafil (Viagra) can interact with beta-blockers and cause a further drop in blood pressure. However, the priority is addressing the abnormal heart rate and blood pressure from option A before focusing on this interaction. The nurse should still monitor the patient closely for any significant changes in blood pressure, but the primary concern is not the interaction here.

C. Positional vertigo and wheezing. While wheezing could be a concern (as beta-blockers can exacerbate bronchospasm in patients with asthma or chronic lung conditions), positional vertigo may be more related to hypotension from the atenolol. Nonetheless, the priority here remains the low heart rate and blood pressure in option A, which is a more immediate concern.

D. Restlessness and mild confusion. These could be side effects or signs of an adverse reaction to atenolol, but they are less urgent compared to the low heart rate and blood pressure found in option A. The nurse should still assess the patient's mental status but prioritize contacting the provider for the more critical findings.

A. Administering aggressive medical interventions to prolong life: In the end stages of Huntington's Disease, aggressive medical interventions are generally not the priority. Huntington's is a progressive neurodegenerative disease, and prolonging life without regard to the patient's quality of life is usually not the focus. The emphasis in end-of-life care is on comfort and symptom management rather than aggressive treatments.

B. Encouraging the patient to engage in physical therapy and exercise: While physical therapy can be important earlier in the disease progression to help maintain function and mobility, in the end stages of Huntington's Disease, the patient's focus is more on comfort care. At this point, physical therapy may not be practical or helpful in improving quality of life, so it is not the primary consideration.

C. Providing comfort care and managing symptoms according to patient's wishes: This is correct. The most important consideration in end-of-life care for a patient with Huntington's Disease is to focus on comfort and symptom management. This includes addressing pain, managing emotional and psychological symptoms, and ensuring that care aligns with the patient's wishes, values, and goals. End-of-life care should prioritize maintaining dignity and ensuring the patient's comfort.

D. Providing respite care and support for the patient's family: While providing respite care and family support are very important aspects of caregiving, the most important consideration is the patient's comfort and managing symptoms in alignment with their wishes. Respite care for the family is important but is not the central focus of end-of-life care for the patient.
