A nurse is assessing a young child and suspects coarctation of the aorta based on which finding?

A.

Diastolic murmur.

B.

Hypotension.

C.

Excessive crying.

D.

Unequal upper and lower extremity pulses.

Answer and Explanation

The Correct Answer is D

Choice A rationale

 

A diastolic murmur is not a typical finding in coarctation of the aorta. This condition is more commonly associated with systolic murmurs.

 

Choice B rationale

 

Hypotension is not a common finding in coarctation of the aorta. In fact, hypertension in the upper extremities is more typical due to the narrowing of the aorta.

 

Choice C rationale

 

Excessive crying is not a specific indicator of coarctation of the aorta. It can be a symptom of many different conditions and is not diagnostic.

 

Choice D rationale

 

Unequal upper and lower extremity pulses are a key finding in coarctation of the aorta. The narrowing of the aorta causes reduced blood flow to the lower extremities, resulting in weaker pulses compared to the upper extremities.

Correct Answer is A

Explanation

Choice A rationale

Obtaining an influenza vaccine annually is crucial for individuals with type 1 diabetes mellitus. People with diabetes are at a higher risk of complications from infections, including influenza. The flu can lead to elevated blood sugar levels and potentially worsen diabetes control.
Therefore, getting the flu vaccine can help prevent or reduce the severity of the flu and its complications.

Choice B rationale

Administering glucagon is used for severe hypoglycemia, not hyperglycemia. Glucagon is a hormone that raises blood glucose levels by stimulating the liver to release stored glucose. It is typically used in emergency situations when a person with diabetes has very low blood sugar and is unable to consume sugar orally.

Choice C rationale

Insulin should be injected into subcutaneous tissue, not the deltoid muscle. The preferred injection sites for insulin are areas with more subcutaneous fat, such as the abdomen, thighs, buttocks, and upper arms. Injecting insulin into muscle tissue can lead to faster absorption and unpredictable blood glucose levels.

Choice D rationale

Glyburide is an oral medication used to treat type 2 diabetes, not type 1 diabetes. Type 1 diabetes requires insulin therapy because the body does not produce insulin. Glyburide works by stimulating the pancreas to release more insulin, which is not effective for individuals with type 1 diabetes who have little to no insulin production.

Correct Answer is C

Explanation

Choice A rationale

Distended neck veins are not a typical manifestation of pyloric stenosis. This condition primarily affects the gastrointestinal system, leading to symptoms related to feeding and digestion rather than cardiovascular symptoms like distended neck veins.

Choice B rationale

Red currant jelly stools are associated with intussusception, not pyloric stenosis. Intussusception involves the telescoping of one part of the intestine into another, leading to obstruction and the characteristic stool appearance.

Choice C rationale

Projectile vomiting is a hallmark symptom of pyloric stenosis. This occurs due to the obstruction at the pylorus, which prevents food from passing into the small intestine, leading to forceful expulsion of stomach contents.

Choice D rationale

A ridged abdomen is not a typical symptom of pyloric stenosis. While the abdomen may be distended due to the obstruction, the primary symptom is projectile vomiting.
