Correct Answer: C

Rationale: The correct answer is C: Dizziness and shakiness. This indicates hypoglycemia, a potential side effect of insulin therapy. Dizziness and shakiness are classic signs of low blood sugar levels, which can be dangerous if left untreated. Headache and blurred vision (Option A) can occur with high blood sugar. Increased thirst and urination (Option B) are symptoms of hyperglycemia. Dry mouth and skin (Option D) are not immediate concerns related to insulin therapy.

Correct Answer: B

Rationale: Step 1: Administering IV antibiotics is important for treating infections, but in this case, the focus is on addressing the pain associated with the deep wound infection. Step 2: Administering pain relief helps improve the client's comfort and quality of life while the infection is being treated. Step 3: Changing the dressing is essential for wound care but does not directly address the client's pain from the infection. Step 4: Performing a CT scan may be necessary to assess the extent of the infection, but it does not directly provide immediate relief for the client's pain. Summary: Administering pain relief is the most appropriate intervention as it directly addresses the client's symptoms and improves their comfort level during the treatment of the deep wound infection.

Correct Answer: B

Rationale: Mammography is used to detect tumors in the breast tissue by taking X-ray images. Tumors can be cancerous or benign, making early detection crucial for treatment. Pain (A) is a symptom, not detected by mammography. Edema (C) is swelling caused by fluid retention, not a primary target of mammography. Epilepsy (D) is a neurological disorder, unrelated to mammography's purpose. Therefore, the correct answer is B.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. The first priority in caring for a client experiencing a stroke is to ensure adequate oxygen supply to the brain, as lack of oxygen can lead to further brain damage. Administering oxygen helps improve oxygenation and can prevent complications. Administering morphine (B) is not recommended as it can mask symptoms and delay diagnosis. Administering IV fluids (C) may be necessary but is not the first priority. Administering fibrinolytics (D) is a time-sensitive intervention for ischemic stroke but should be done after proper evaluation and confirmation of the type of stroke.

Correct Answer: B

Rationale: The correct answer is B because encouraging early ambulation is a priority post-operative intervention for a patient following a hip replacement. Early ambulation helps prevent complications such as blood clots, muscle weakness, and pneumonia. It also promotes circulation and aids in the patient's recovery. Administering pain medications (A) is important but not the top priority. Monitoring for signs of infection (C) is crucial, but ambulation takes precedence. Providing wound care (D) is essential but can be done after ensuring the patient's mobility.
