A patient presents with symptoms of polyuria, polydipsia, and polyphagia. Laboratory tests reveal hyperglycemia and glycosuria. Which type of diabetes mellitus is the patient most likely experiencing?

Correct Answer: A

Rationale: The patient is most likely experiencing Type 1 diabetes mellitus based on the presentation of polyuria, polydipsia, polyphagia, hyperglycemia, and glycosuria. Type 1 diabetes is characterized by autoimmune destruction of the beta cells in the pancreas, leading to absolute insulin deficiency. This results in high blood sugar levels (hyperglycemia) and glucose spilling into the urine (glycosuria). Patients with Type 1 diabetes often present with the classic symptoms of polyuria (increased urination), polydipsia (increased thirst), and polyphagia (increased hunger) due to the body's inability to utilize glucose for energy effectively. Management of Type 1 diabetes typically involves lifelong insulin therapy to maintain blood sugar levels within a target range.

Correct Answer: D

Rationale: Administering oxygen therapy is the priority nursing intervention for managing a patient with COPD experiencing respiratory distress. In COPD, the patient's lungs are less efficient at oxygen exchange, leading to hypoxemia. Oxygen therapy helps improve oxygenation in the body and alleviates respiratory distress in these patients. Positioning the patient in high Fowler's position can also help improve lung expansion, but providing supplemental oxygen takes precedence in addressing the underlying hypoxemia. Administering bronchodilators and performing chest physiotherapy aim to manage airway obstruction and promote airway clearance, but ensuring the patient has adequate oxygenation is crucial in the immediate management of respiratory distress in COPD.

Correct Answer: C

Rationale: Insulin glargine (Lantus) is a long-acting insulin that is typically administered once daily at the same time each day to help maintain a steady level of insulin in the body. It is important to rotate injection sites within the same body region (such as the abdomen, thigh, or upper arm) to prevent lipodystrophy (lumpiness or dents in the skin) and to ensure consistent absorption of the insulin. Proper rotation of injection sites helps to prevent tissue damage and ensures optimal insulin absorption, improving the effectiveness of insulin therapy. It is not necessary to inject insulin glargine before meals, vigorously shake the vial, or administer it with a rapid-acting insulin.

Correct Answer: B

Rationale: Atorvastatin is a medication commonly used for lipid-lowering therapy to reduce cholesterol levels and decrease the risk of cardiovascular events. However, one of the potential side effects of statin medications such as atorvastatin is liver injury. Therefore, monitoring liver function tests, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, is crucial during atorvastatin therapy.

Correct Answer: B

Rationale: Monitoring oxygen saturation with pulse oximetry is essential for preventing respiratory depression in a patient prescribed an opioid analgesic. Opioid analgesics can suppress the respiratory drive, leading to respiratory depression. By constantly monitoring the patient's oxygen saturation levels with pulse oximetry, nurses can promptly detect any signs of respiratory depression and intervene early to prevent serious complications. This allows for timely adjustments in the medication dosage or administration of other supportive measures to maintain adequate oxygenation and prevent respiratory compromise. Administering naloxone prophylactically may be necessary in case of an opioid overdose but is not typically done as a preventive measure. Encouraging deep breathing exercises can help prevent respiratory complications postoperatively but may not be sufficient in the presence of opioid-induced respiratory depression. Administering bronchodilators as needed is not directly related to preventing respiratory depression caused by opioid analgesics.
