Question 1 of 5
Diabetes mellitus is a disorder that affects 3.1 out of every 1000 children younger than 20 years old. It is characterized by an absence of, or marked decrease in, circulating insulin. When teaching a newly diagnosed diabetes client, the nurse includes information on the functions of insulin:
Correct Answer: A
Rationale: Lack of insulin causes glycogenolysis, catabolism, and hyperglycemia. Insulin promotes the conversion of glucose to glycogen for storage and regulates the rate at which carbohydrates are used by cells for energy. Insulin is anabolic in nature. Glucose stimulates protein synthesis within the tissue and inhibits the breakdown of protein into amino acids.
Question 2 of 5
An obstetrical client is admitted in active labor. During examination,the nurse notes a papular lesion on the perineum. Which initial action is most appropriate?
Correct Answer: B
Rationale: A papular lesion on the perineum during labor could indicate an infectious condition (e.g. herpes simplex virus) which poses risks to the newborn. Reporting to the physician is the most appropriate initial action to determine management such as the need for a C-section.
Question 3 of 5
The client is diagnosed with glaucoma. Which medication is most likely to be prescribed?
Correct Answer: A
Rationale: Timolol, a beta-blocker, is commonly prescribed for glaucoma to reduce intraocular pressure by decreasing aqueous humor production. Atropine increases pressure, pilocarpine is less common, and acetazolamide is used acutely.
Question 4 of 5
In assessing cardiovascular clients with progression of aortic stenosis, the nurse should be aware that there is typically:
Correct Answer: D
Rationale: These signs are seen in pulmonic stenosis or in response to pulmonary congestion and edema and mitral stenosis. These signs are seen primarily in mitral stenosis or as a late sign in aortic stenosis after left ventricular failure. These signs are seen primarily in right-sided heart valve dysfunction. Left ventricular hypertrophy occurs to increase muscle mass and overcome the stenosis; left ventricular pressures increase as left ventricular volume increases owing to insufficient emptying.
Question 5 of 5
The nurse has been assigned a client who delivered a 6-lb, 12-oz baby boy vaginally 40 minutes ago. The initial assessment of greatest importance for this client would be:
Correct Answer: D
Rationale: The length of labor has little bearing on the fourth stage of labor. The type of labor and delivery is significant. The type of episiotomy will affect the client's comfort level. However, the nurse's assessment and implementations center on prevention of hemorrhage during the fourth stage of labor. The amount of bleeding from the episiotomy or hematoma formation is of higher priority than the type of episiotomy. The amount of IV fluid to be infused is a nursing function to be attended to; however, it is lower in priority than determining if hemorrhaging is occurring. Character of the fundus would be the priority nursing assessment because changes in uterine tone may identify possible postpartum hemorrhage.
