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
Upper extremity hypotension
Weak femoral pulses.
Increased intracranial pressure
The Correct Answer is C
This is because coarctation of the aorta is a congenital condition where the aorta is narrow, usually in the area where the ductus arteriosus inserts. This causes a decrease in blood flow to the lower body, resulting in weak or absent pulses in the femoral arteries.
The other choices are incorrect for the following reasons:
- Choice A, frequent nosebleeds, is not a typical sign of coarctation of the aorta.
Nosebleeds can be caused by many factors, such as dry air, allergies, trauma, or bleeding disorders.
- Choice B, upper extremity hypotension, is also not a common finding in coarctation of the aorta. In fact, patients with this condition may have high blood pressure in the upper extremities due to the increased resistance of the narrowed aorta.
- Choice D, increased intracranial pressure, is not directly related to coarctation of the aorta.
Increased intracranial pressure can be caused by various conditions that affect the brain, such as head injury, stroke, infection, or tumor.
Normal ranges for blood pressure and pulse vary depending on age, sex, and health status.
However, some general guidelines are:
- Blood pressure: less than 120/80 mmHg for adults; less than 95/65 mmHg for infants.
- Pulse: 60 to 100 beats per minute for adults; 100 to 160 beats per minute for infants.

Correct Answer is D
Explanation
Answer:D. Troponin T test
Rationale:
A. Creatine kinase (CK) test: While creatine kinase isoenzymes, including CK-MB, can be elevated following myocardial infarction (MI), they are not specific to cardiac muscle injury. CK is found in various tissues throughout the body, so elevated levels can also indicate damage to skeletal muscle or brain tissue, among other sources.
B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is a cardiac-specific isoform of creatine kinase, and elevated levels can indicate myocardial injury, particularly in the context of an acute MI. However, troponin T is a more sensitive and specific marker for myocardial injury.
C. Brain natriuretic peptide (BNP) test: Brain natriuretic peptide is primarily used in the diagnosis and management of heart failure. While elevated BNP levels can indicate heart muscle strain or stress, they are not specific markers for acute myocardial infarction or early injury to the cardiac muscle.
D. Troponin T test: This is the correct answer. Troponin T is a highly specific marker for cardiac muscle injury. Elevated troponin levels can be detected within hours of myocardial infarction and persist for several days, making it an essential tool in the diagnosis of acute coronary syndromes, including myocardial infarction. Troponin T is considered one of the gold standard biomarkers for detecting early injury to the cardiac muscle.
Correct Answer is D
Explanation
The correct answer is choice D. Sit at or below the client’s eye level during feedings.
This action helps the client feel more comfortable and less intimidated by the nurse. It also allows the nurse to observe the client’s swallowing and signs of aspiration more easily.
Choice A is wrong because talking with the client during her feeding can distract her from swallowing properly and increase the risk of aspiration.
The nurse should encourage the client to focus on eating and avoid conversation until the feeding is over.
Choice B is wrong because discouraging the client from coughing during feedings can prevent her from clearing her airway and expelling any food particles that might have entered the trachea.
The nurse should monitor the client for coughing, choking, or changes in voice quality, which are indicators of aspiration.
Choice C is wrong because instructing the client to lift her chin when swallowing can actually make swallowing more difficult and increase the risk of aspiration.
The nurse should instruct the client to tuck her chin when swallowing, which helps close off the trachea and direct food into the esophagus.
