Which insulin requires the nurse to wait until the meal trays are being delivered to the client before administering?

Humulin N

Humalog

Lantus

NPH insulin

Answer and Explanation

The Correct Answer is B

A. Humulin N: Humulin N is an intermediate-acting insulin with an onset of 1 to 2 hours. It does not act rapidly enough to require coordination with meal delivery and can be given well in advance of meals to provide basal coverage.

B. Humalog: Humalog (insulin lispro) is a rapid-acting insulin that begins to lower blood glucose within 15 minutes of administration. To prevent hypoglycemia, it should be given only when the meal is about to be consumed or when the tray is present.

C. Lantus: Lantus (insulin glargine) is a long-acting basal insulin with no significant peak and a slow onset. It is typically administered once daily, regardless of meal timing, and does not need to be timed with food delivery.

D. NPH insulin: NPH insulin is another intermediate-acting insulin with a slower onset than rapid-acting insulins. While it may be administered before meals, it does not require the immediate presence of food and has a delayed peak.

Correct Answer is B

Explanation

A. unpredictable behaviors: While altered behavior or confusion can occur with hypoglycemia, these are often later symptoms. Diaphoresis is typically one of the earliest and most noticeable signs, helping prompt faster recognition and intervention.

B. diaphoresis: Diaphoresis, or excessive sweating, is a classic sympathetic nervous system response to hypoglycemia. It is an early warning sign that glucose levels are dropping and immediate treatment is needed to prevent further deterioration.

C. flushing of the face: Flushed skin is more commonly associated with hyperglycemia or hormonal responses rather than hypoglycemia. It does not serve as a reliable indicator of low blood glucose levels in diabetic clients.

D. fruity breath: Fruity or acetone-like breath is a hallmark sign of diabetic ketoacidosis, which occurs in hyperglycemia, not hypoglycemia. It results from the breakdown of fat and ketone accumulation in the blood.

A. sucralfate B. bisacodyl C. omeprazole D. prochlorperazine

Correct Answer is D

Explanation

A. sucralfate: Sucralfate is a gastrointestinal protectant used to treat and prevent ulcers by forming a barrier over damaged mucosa. It does not affect the vomiting center or chemoreceptor trigger zone and has no antiemetic properties.

B. bisacodyl: Bisacodyl is a stimulant laxative used to treat constipation by increasing peristalsis and fluid accumulation in the colon. It is not used for nausea or vomiting and has no action on the central nervous system.

C. omeprazole: Omeprazole is a proton pump inhibitor that decreases gastric acid secretion. It is used to manage GERD and peptic ulcers but has no antiemetic effects or influence on the chemoreceptor trigger zone.

D. prochlorperazine: Prochlorperazine is a phenothiazine antiemetic that works by blocking dopamine receptors in the chemoreceptor trigger zone. It is frequently used to manage nausea, vomiting, and vertigo.
