A nurse is teaching a client with diabetes about insulin administration. What is the most important point to emphasize?

Correct Answer: B

Rationale: The most important point to emphasize when teaching a client with diabetes about insulin administration is to administer insulin before meals as prescribed. This is crucial for maintaining proper blood sugar control throughout the day. Choice A is incorrect because blood sugar levels need to be monitored multiple times a day, not just once in the morning. Choice C is incorrect because insulin should be administered according to the prescribed schedule, not only when feeling unwell. Choice D is incorrect because blood sugar monitoring should be done at various times during the day, not just in the evening.

Correct Answer: A

Rationale: Correct Answer: A. When assessing a patient with a potential myocardial infarction, it is crucial to assess symptoms, monitor vital signs like blood pressure and heart rate, and order an electrocardiogram (ECG) to evaluate for cardiac abnormalities. Choice B is incorrect because administering medications should be based on the findings of the assessment and diagnostic tests, not administered indiscriminately. Choice C is incorrect because the administration of thrombolytics and oxygen therapy should be based on specific criteria and should be done in a controlled setting. Choice D is incorrect as educating the patient on lifestyle changes is important for prevention but is not the immediate priority when managing a potential myocardial infarction.

Correct Answer: A

Rationale: Correct answer: Monitoring for signs of infection and ensuring airway patency is crucial in managing a patient with a tracheostomy. This involves observing for redness, swelling, or discharge at the stoma site, as well as assessing for any signs of respiratory distress. Choice B, suctioning airway secretions and providing humidified air, is important for maintaining airway hygiene but may not be the initial assessment priority. Choice C, inspecting the stoma site and cleaning with saline, is part of routine tracheostomy care but does not address immediate assessment and management needs. Choice D, providing education on tracheostomy care, is valuable but not the primary action required in the assessment and management of a patient with a tracheostomy.

Correct Answer: A

Rationale: The correct way to assess and manage a patient with dehydration is to assess skin turgor and monitor intake/output. Skin turgor assessment helps in evaluating the degree of dehydration, while monitoring intake/output aids in maintaining fluid balance. Encouraging oral fluids only (Choice B) may not be sufficient for moderate to severe dehydration as patients may need intravenous fluids (IV) to rapidly rehydrate. Administering IV fluids immediately (Choice C) is not always the first step unless the patient is severely dehydrated. Checking for electrolyte imbalance and administering fluids (Choice D) is important but comes after assessing skin turgor and intake/output in the management of dehydration.

Correct Answer: A

Rationale: Administering oxygen and calling for emergency assistance are the immediate priorities when managing a suspected pulmonary embolism. Oxygen helps support the patient's respiratory function, while emergency assistance is crucial for further evaluation and treatment. Positioning the patient in a prone position or giving fluids can worsen the condition by impeding blood flow. Administering anticoagulants may be part of the treatment plan but is not the initial response. Thrombolytics and chest physiotherapy are not first-line treatments for suspected pulmonary embolism and can even be harmful without prior evaluation.
