A client is receiving 10 mL/hr of a prescribed regular insulin infusion. The label on the bag reads 50 units of regular insulin in 100 mL of 0.9% saline. How many units of insulin is the client receiving every hour? Fill in the blank. Round your answer to the nearest whole number.
A. 5 units/hour
The correct answer is 5 units/hour. To calculate the units of insulin per hour, we need to use the following formula: units of insulin per hour = (units of insulin in the bag / volume of the bag) x infusion rate Plugging in the given values, we get: units of insulin per hour = (50 / 100) x 10 units of insulin per hour = 0.5 x 10 units of insulin per hour = 5 Therefore, the client is receiving 5 units of insulin every hour.
B. 10 units/hour
This is incorrect because it assumes that the infusion rate is equal to the units of insulin per hour, which is not true.
C. 20 units/hour
This is incorrect because it multiplies the units of insulin in the bag by the infusion rate, which is too high.
D. 15 units/hour
This is incorrect because it adds the units of insulin in the bag and the infusion rate, which is also too high.

Full Explanation
Choice A rationale: The correct answer is 5 units/hour. To calculate the units of insulin per hour, we need to use the following formula: units of insulin per hour = (units of insulin in the bag / volume of the bag) x infusion rate
Plugging in the given values, we get:
units of insulin per hour = (50 / 100) x 10 units of insulin per hour = 0.5 x 10
units of insulin per hour = 5
Therefore, the client is receiving 5 units of insulin every hour.
Choice B rationale: This is incorrect because it assumes that the infusion rate is equal to the units of insulin per hour, which is not true.
Choice C rationale: This is incorrect because it multiplies the units of insulin in the bag by the infusion rate, which is too high.
Choice D rationale: This is incorrect because it adds the units of insulin in the bag and the infusion rate, which is also too high.

While assessing a male client, a nurse observes that the client has a small penis, long legs, short trunk, enlarged breast tissues, small testicles, and sexual dysfunction. What diagnosis does the nurse suspect from these findings?
A. Cri du chat "cry of the cat,"
Cri du chat syndrome involves a high-pitched cry in infants and other distinct physical and developmental features, but it doesn't present with the described symptoms.
B. Klinefelter syndrome
Klinefelter syndrome, characterized by an extra X chromosome (XXY) in males, typically presents with small testicles, gynecomastia (enlarged breast tissues), sexual dysfunction, and altered body proportions, such as long legs and a shorter trunk, aligning with the client's symptoms.
C. Patau syndrome
Patau syndrome (Trisomy 13) manifests with severe developmental issues, facial abnormalities, and other physical malformations, but the described symptoms are not typically associated with this syndrome.
D. Turner's syndrome
Turner syndrome involves females with a missing or partially missing X chromosome (45, X), resulting in specific physical features and medical problems not consistent with the described symptoms in a male client.

The nurse is most likely to report which finding to the primary care provider for a client who has an established colostomy?
A. The skin under the appliance looks red briefly after removing the appliance.
Redness briefly after removing the appliance might be common due to increased blood flow but does not necessarily indicate an issue.
B. The stoma color is a deep red-purple.
A deep red-purple stoma color can suggest impaired blood supply to the stoma and requires immediate attention.
C. An ascending colostomy delivers liquid feces.
The consistency of output from the colostomy may vary based on the site and type of colostomy and might not necessarily be concerning.
D. The stoma extends 1/2 inch above the abdomen.
The length of the stoma can vary and usually depends on the type of colostomy, and 1/2 inch above the abdomen is within an acceptable range.

Which complication is suspected in a client whose blood sugar is less than 30 mg/dL?
A. Seizure
Hypoglycemia (blood sugar less than 30 mg/dL) can lead to seizures due to inadequate glucose supply to the brain.
B. Anorexia
Anorexia (loss of appetite) is not directly associated with low blood sugar but can be a symptom of other conditions.
C. Anhidrosis
Anhidrosis refers to the inability to sweat and is not typically associated with low blood sugar.
D. Bradycardia
Bradycardia (slow heart rate) can be a symptom of severe hypoglycemia but is not the primary complication expected at this blood sugar level.
