Which is a rapid-acting insulin with an onset of action of less than 15 minutes?

Insulin glargine (Lantus)

Insulin detemir (Levemir)

Insulin aspart (NovoLog)

Regular insulin (Humulin R)

Answer and Explanation

The Correct Answer is C

Choice A reason: Insulin glargine is a long-acting insulin with an onset of 1–2 hours, providing basal coverage for 24 hours. It does not act rapidly to control postprandial glucose, unlike rapid-acting insulins, making this choice incorrect for the question.

Choice B reason: Insulin detemir is a long-acting insulin with an onset of 1–2 hours, used for steady glucose control. It lacks the rapid onset (<15 minutes) required for immediate postprandial glucose management, making this choice incorrect.

Choice C reason: Insulin aspart is a rapid-acting insulin analog with an onset of 10–15 minutes, peaking in 1–3 hours. It mimics the body’s insulin response to meals, effectively controlling postprandial glucose, making this the correct choice.

Choice D reason: Regular insulin has an onset of 30–60 minutes, slower than rapid-acting insulins. It is used for short-term glucose control but does not meet the <15-minute onset criterion, making this choice incorrect.

Correct Answer is ["A","C","D","E"]

Explanation

Choice A reason: Ensuring proper fit of the TLSO is critical to stabilize the spine effectively, preventing further injury. An ill-fitting brace can cause misalignment, pressure sores, or reduced efficacy, as it fails to immobilize the thoracolumbar region, making this a key nursing priority.

Choice B reason: How the patient sleeps with the brace is not a primary nursing priority. While comfort during sleep matters, the TLSO is typically worn as prescribed, and sleep position is secondary to ensuring fit, breathing, education, and skin care, making this choice incorrect.

Choice C reason: Monitoring breathing is essential, as a TLSO can restrict chest expansion, potentially reducing tidal volume and causing respiratory distress. Nurses must assess respiratory rate and oxygen saturation to ensure the brace does not compromise ventilation, making this a critical priority.

Choice D reason: Educating the patient and family about the TLSO’s purpose and care ensures compliance and proper use. Understanding how to wear, clean, and adjust the brace prevents complications like skin breakdown or ineffective stabilization, making this a key nursing responsibility.

Choice E reason: Skin integrity is a priority, as prolonged brace use can cause pressure ulcers or irritation. Nurses must inspect skin under the TLSO regularly, ensuring proper padding and hygiene to prevent breakdown, especially in immobile patients, making this a critical care aspect.

A. The client drinks 2 liters of liquids daily B. The client eats foods high in tyramine C. The client runs 4 miles outdoors every afternoon D. The client eats 2 to 3 gm of sodium-containing foods daily

Correct Answer is C

Explanation

Choice A reason: Drinking 2 liters of liquids daily supports hydration, reducing lithium toxicity risk by promoting renal excretion. Lithium is cleared by the kidneys, and adequate fluid intake prevents concentration, making this choice incorrect.

Choice B reason: Tyramine is relevant to MAOI antidepressants, causing hypertensive crises, not lithium. Lithium toxicity is related to renal clearance and electrolyte balance, not dietary tyramine, making this choice incorrect for lithium risks.

Choice C reason: Running 4 miles outdoors daily causes significant fluid loss through sweat, reducing blood volume and impairing lithium excretion by the kidneys. This increases lithium concentration, risking toxicity, making this the correct risk factor.

Choice D reason: Eating 2–3 gm of sodium daily is within normal limits and helps maintain electrolyte balance, aiding lithium excretion. Low sodium increases lithium retention, but this amount is not a risk, making this choice incorrect.
