A nurse is caring for an infant who has coarctation of the aorta. Which of the following should the nurse identify as an expected finding?

Frequent nosebleeds

Increased intracranial pressure

Upper extremity hypotension

Weak femoral pulses

Answer and Explanation

The Correct Answer is D

A. Frequent nosebleeds: While hypertension can occur in coarctation of the aorta, frequent nosebleeds are not a typical finding associated with this condition.

B. Increased intracranial pressure: This is not a direct finding of coarctation of the aorta. Increased intracranial pressure may be related to other conditions, but it is not specifically expected in this context.

C. Upper extremity hypotension: In coarctation of the aorta, the upper extremities usually experience higher blood pressure due to the narrowing of the aorta distal to the branches supplying the arms. Therefore, hypotension in the upper extremities is not expected.

D. Weak femoral pulses: This is an expected finding in coarctation of the aorta, as the narrowing of the aorta can lead to decreased blood flow to the lower body, resulting in weak or diminished femoral pulses compared to the upper extremities.

Correct Answer is C

Explanation

A) Apply petroleum jelly to soothe the mucous membranes: This is not advisable, as petroleum jelly is flammable and can pose a risk when using oxygen. Instead, a water-based lubricant is safer for mucous membranes.

B) Clean the equipment with an alcohol-based cleaning product: Alcohol is flammable and not recommended for cleaning oxygen equipment. Mild soap and water are more suitable for maintaining cleanliness.

C) Avoid using nail polish remover around the client: This is the correct answer. Nail polish remover often contains acetone, which is flammable and should be avoided in environments where oxygen is in use to prevent fire hazards.

D) Use synthetic fabrics for the client's bedding: This is incorrect. Natural fabrics like cotton are preferred because synthetic fabrics can create static electricity, increasing the risk of fire in the presence of oxygen.

A. Fasting blood glucose 100 mg/dL B. Hgb 14 g/dL C. Heart rate 58/min D. WBC count 2,900/mm3

Correct Answer is D

Explanation

A. Fasting blood glucose 100 mg/dL: This level is within the normal range and does not contraindicate the use of clozapine. Monitoring blood glucose is important due to the risk of metabolic syndrome, but a normal level is not a concern.

B. Hgb 14 g/dL: Hemoglobin levels in this range are normal and indicate adequate oxygen-carrying capacity. This finding does not contraindicate the use of clozapine.

C. Heart rate 58/min: A heart rate of 58 beats per minute is considered bradycardic but does not directly contraindicate the use of clozapine. Monitoring cardiovascular health is important, but this alone is not a reason to withhold the medication.

D. WBC count 2,900/mm³: This finding is significant because clozapine can cause agranulocytosis, a potentially life-threatening decrease in white blood cells. A WBC count below 3,000/mm³ is a contraindication for clozapine administration, as it increases the risk of infection and other complications. Therefore, this finding indicates that clozapine should not be administered.
