A six-month-old infant has been admitted to the emergency room with febrile seizures. In the teaching of the parents, the nurse states that:

  1. Sustained temperature elevation over 103F is generally related to febrile seizures
  2. Febrile seizures do not usually recur
  3. There is little risk of neurological deficit and mental retardation as sequelae to febrile seizures
  4. Febrile seizures are associated with diseases of the central nervous system

Answer(s): C

Explanation:

(A) The temperature elevation related to febrile seizures generally exceeds 101F, and seizures occur during the temperature rise rather than after a prolonged elevation. (B) Febrile seizures may recur and are more likely to do so when the first seizure occurs in the 1st year of life. (C) There is little risk of neurological deficit, mental retardation, or altered behavior secondary to febrile seizures. (D) Febrile seizures are associated with disease of the central nervous system.

The primary reason that an increase in heart rate (100 bpm) detrimental to the client with a myocardial infarction (MI) is that:

  1. Stroke volume and blood pressure will drop proportionately
  2. Systolic ejection time will decrease, thereby decreasing cardiac output
  3. Decreased contractile strength will occur due to decreased filling time
  4. Decreased coronary artery perfusion due to decreased diastolic filling time will occur, which will increase ischemic damage to the myocardium

Answer(s): D

Explanation:

(A) Decreased stroke volume and blood pressure will occur secondary to decreased diastolic filling. (B) Tachycardia primarily decreases diastole; systolic time changes very little. (C) Contractility decreases owing to the decreased filling time and decreased time for fiber lengthening. (D) Decreased O2 supply due to decreased time for filling of the coronary arteriesincreases ischemia and infarct size. Tachycardia primarily robs the heart of diastolic time, which is the primary time for coronary artery filling.
