Which of the following would Nurse Tony suppose to regard as a cardinal manifestation or symptom of digoxin toxicity to his patient Clay diagnosed with heart failure?

Correct Answer: C

Rationale: Digoxin is a medication commonly used to treat heart failure. One of the cardinal manifestations of digoxin toxicity is extreme bradycardia, which is characterized by a slower than normal heart rate. This can be a serious and potentially life-threatening symptom of digoxin toxicity, as it indicates that the medication is affecting the heart's electrical conduction system. Other symptoms of digoxin toxicity can include nausea, vomiting, vision changes, and confusion, but extreme bradycardia is a prominent sign that Nurse Tony should be vigilant for in his patient Clay, who has been diagnosed with heart failure.

Correct Answer: B

Rationale: Tetralogy of Fallot is a heart defect that involves four specific abnormalities in the heart's structure. One of these abnormalities is a ventricular septal defect, which results in a mixing of oxygenated and deoxygenated blood. This leads to inadequate oxygenation of tissues because some of the blood that is pumped out to the body is not fully oxygenated. As a result, the child may experience fatigue and poor activity tolerance due to the reduced oxygen supply to the tissues and organs. This is why the nurse would expect to see these symptoms in a 3-year-old with tetralogy of Fallot.

Correct Answer: D

Rationale: The correct information that the nurse should include in the teaching is that clothing should always fit loosely over the harness. This is important to prevent restriction of movement and ensure comfort for the child wearing the Pavlik harness. Tight clothing can cause discomfort, skin irritation, and interfere with the effectiveness of the harness in positioning the hip properly. Parents should be advised to choose clothing that is loose-fitting and does not put pressure on the harness or the child's skin.

Correct Answer: B

Rationale: Hemophilia is an X-linked recessive genetic disorder, meaning it is carried on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. In this scenario, the female carrier has one X chromosome with the hemophilia gene and one normal X chromosome. When she has children, she has a 50% chance of passing on the X chromosome with the hemophilia gene to her sons. Therefore, half the male children will inherit hemophilia, while half will not. Daughters, on the other hand, have a 50% chance of inheriting the X chromosome with the hemophilia gene but since it is a recessive disorder, they will be carriers of hemophilia rather than having the disease itself.
