A nurse is preparing to administer a blood transfusion. What is the first action?

Correct Answer: B

Rationale: The correct first action when preparing to administer a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to prevent transfusion reactions and complications. Option A is incorrect because blood transfusions should not be administered through an IV push due to the risk of rapid infusion and adverse reactions. Option C is incorrect because blood should be transfused at room temperature, not body temperature. Option D is incorrect because it is not necessary for the client to eat before a blood transfusion.

Correct Answer: A

Rationale: Correct! When assessing for dehydration in a pediatric patient, checking for dry mouth and decreased urine output are crucial indicators. Dry mouth indicates reduced fluid intake or dehydration, while decreased urine output suggests decreased renal perfusion secondary to dehydration. Skin turgor and capillary refill are more indicative of perfusion status rather than dehydration specifically. Lethargy and irritability can be present in dehydrated patients but are more general signs of illness. Monitoring blood pressure and heart rate are important in assessing dehydration severity but are not the initial signs used for assessment.

Correct Answer: A

Rationale: The correct answer is A: Immobility and decreased lung function. Older adults with immobility and decreased lung function are at a higher risk of developing pneumonia. Immobility can lead to decreased lung expansion and impaired clearance of secretions, predisposing to pneumonia. While poor hygiene, aspiration, use of respiratory equipment, medications, poor nutritional status, and compromised immune system can also contribute to pneumonia risk, they are not as directly associated with pneumonia in older adults as immobility and decreased lung function.

Correct Answer: A

Rationale: The correct answer is A: 'Heart disease and stroke.' Untreated hypertension can lead to various complications, including heart disease and stroke. These are common outcomes of long-term high blood pressure. Choice B, 'Kidney failure and vision loss,' is incorrect as kidney failure and vision loss are more commonly associated with diabetic complications rather than untreated hypertension. Choice C, 'Pulmonary embolism and arrhythmias,' while serious, are not among the primary complications of untreated hypertension. Choice D, 'Blood clots and gastrointestinal bleeding,' are not typical complications of untreated hypertension but can occur due to other conditions such as blood clotting disorders or gastrointestinal diseases.

Correct Answer: A

Rationale: The correct answer is A: Monitor for signs of infection and administer pain relief. In postoperative care for a patient with a hip replacement, it is crucial for the nurse to monitor for signs of infection, such as increased pain, redness, swelling, or drainage from the surgical site. Administering pain relief is also important to ensure the patient's comfort and aid in their recovery. Choices B, C, and D are incorrect as they do not directly relate to the immediate postoperative care needs of a patient with a hip replacement. Ensuring a low-calcium diet, using crutches, or monitoring for deep vein thrombosis are not primary responsibilities in the immediate postoperative period for this type of surgery.
