Correct Answer: A

Rationale: In this case, the patient is experiencing respiratory acidosis as indicated by the low pH (7.28), elevated PaCO2 (65 mmHg), and elevated HCO3- (30 mEq/L). The primary acid-base disturbance is respiratory acidosis due to the retention of carbon dioxide (PaCO2 >45 mmHg) leading to an increase in HCO3- as a compensatory mechanism to maintain pH within normal limits. The elevated HCO3- levels (metabolic compensation) are trying to counterbalance the increased PaCO2 levels (respiratory acidosis) by increasing bicarbonate to attempt to normalize the pH. Overall, the ABG analysis shows respiratory acidosis with metabolic compensation in this COPD patient with an acute exacerbation and severe dyspnea.

Correct Answer: D

Rationale: Before any procedure, it is crucial to ensure that you have the proper authorization and guidelines in place. By checking the physician's order and the patient care plan, you confirm that suctioning is indeed needed and that you follow the specific instructions for that patient. This step helps ensure patient safety and effective care delivery. Once you have verified this information, you can proceed with gathering equipment, performing hand hygiene, and assessing the patient's condition as necessary.

Correct Answer: C

Rationale: The most appropriate intervention for a patient with end-stage dementia experiencing agitation and restlessness is to create a calm and soothing environment to promote relaxation. Patients with dementia often respond positively to a familiar and tranquil setting, which can help reduce their symptoms of agitation and restlessness. This approach is preferred over administering antipsychotic medications or recommending physical exercise, as these may not be feasible or beneficial for patients in the advanced stages of dementia. Referring the patient to a psychiatrist may not address the immediate need for symptom management and can be considered if other interventions are ineffective. Creating a calm environment, such as dim lighting, soft music, and familiar objects, can help provide comfort and reduce distress for the patient.

Correct Answer: D

Rationale: Speaking up on behalf of the patient to ensure their needs are met is a key action that demonstrates advocacy by the nurse. Advocacy involves actively supporting and safeguarding the rights of the patient, ensuring that their best interests are being considered within the healthcare system. This may include advocating for appropriate treatment, services, resources, or respect for the patient's autonomy and decision-making. By speaking up for the patient, the nurse is acting as their voice and championing their well-being.

Correct Answer: D

Rationale: The Somogyi effect, also known as rebound hyperglycemia, is a phenomenon observed in patients with diabetes mellitus during sleep. It is characterized by a low blood sugar level (hypoglycemia) followed by high blood sugar (hyperglycemia) in the morning. This occurs due to limited insulin in the body during the night, leading to high blood sugar levels in the morning as a response to the hypoglycemia episode. Too much globulin or albumin are not directly associated with the Somogyi effect. Increasing insulin in the body would rather help prevent the hypoglycemia episode that triggers the rebound hyperglycemia in the Somogyi effect.
