A client with diabetic ketoacidosis (DK

Measure the client's blood pressure manually.

Administer intravenous fluids.

Place the client on oxygen therapy.

Administer subcutaneous insulin.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Measuring blood pressure manually is important in assessing the patient's hemodynamic status, but it is not the priority intervention in diabetic ketoacidosis (DKA). The priority is to address dehydration and electrolyte imbalances.

Choice B rationale

Administering intravenous fluids is the priority intervention for a client with DKA. Rapid, deep respirations (Kussmaul breathing) indicate severe metabolic acidosis and dehydration. IV fluids help to correct fluid deficit, improve perfusion, and decrease blood glucose levels.

Choice C rationale

Oxygen therapy may be beneficial if the client is hypoxic, but it is not the priority intervention for DKA. The primary issue is fluid deficit and metabolic acidosis.

Choice D rationale

Administering subcutaneous insulin is essential for managing hyperglycemia in DKA, but it should be done after initiating IV fluids to avoid rapid shifts in electrolyte balance.

Correct Answer is D

Explanation

Choice A rationale

Visible signs of bone healing on an X-ray would not be expected after Buck's traction. Healing takes longer to become visible on an X-ray.

Choice B rationale

Increased swelling and redness would indicate complications such as infection or thrombophlebitis, not the effectiveness of traction.

Choice C rationale

Improved range of motion would not typically be expected while Buck's traction is in place. The primary purpose is to reduce pain and immobilize the fracture.

Choice D rationale

Decrease in hip pain is a direct indicator of the effectiveness of Buck's traction in alleviating symptoms and preventing further injury to the fractured femur.

A. Complete blood count (CBC). B. Lipid profile. C. Electrocardiogram (ECG). D. Troponin levels.

Correct Answer is D

Explanation

Choice A rationale

A complete blood count (CBC) can provide general information about the body's response to an MI, such as white blood cell count, but it is not definitive for diagnosing an MI.

Choice B rationale

A lipid profile measures cholesterol levels and helps assess cardiovascular risk, but it is not useful for diagnosing an acute MI.

Choice C rationale

An electrocardiogram (ECG) is essential for diagnosing an MI as it shows the heart's electrical activity and can indicate ischemia or infarction.

Choice D rationale

Troponin levels are the most specific and sensitive markers for myocardial infarction. Elevated troponin levels confirm heart muscle damage due to an MI, making it the definitive test.
