A patient who has benign prostatic hyperplasia is experiencing which of the following symptoms?

Choice A rationale

The oral mucosa is the most reliable indicator of central cyanosis because it reflects the oxygenation of central tissues. When there is a lack of oxygen in the bloodstream, the lips and mucous membranes, such as the oral mucosa, appear blue or cyanotic. This is a clear sign that the central tissues are not receiving adequate oxygenation.

Choice B rationale

The sclera of the eye is not a reliable indicator of central cyanosis. The sclera is white and does not change color due to oxygen levels. Instead, it may become yellow in jaundice or red in inflammation but does not reflect central cyanosis.

Choice C rationale

The ear lobes are peripheral areas and do not reliably indicate central cyanosis. Peripheral cyanosis can occur due to local blood flow issues, and ear lobes can appear blue in cold conditions even when central oxygenation is normal.

Choice D rationale

The soles of the feet, similar to the ear lobes, are peripheral areas and not reliable indicators of central cyanosis. Cyanosis in the feet can result from poor peripheral circulation rather than central hypoxia.

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.
