    A nurse caring for several patients on the cardiac unit is told that one is scheduled for implantation of an automatic internal cardioverter-defibrillator. Which of the following patients is most likely to have this procedure?

    • A patient admitted for myocardial infarction without cardiac muscle damage.

    • A post-operative coronary bypass patient. recovering on schedule.

    • A patient with a history of ventricular tachycardia and syncopal episodes.

    • A patient with a history of atrial tachycardia and fatigue.

    Correct Answer
    A. A patient with a history of ventricular tachycardia and syncopal episodes.
    Explanation
    An automatic internal cardioverter-defibrillator delivers an electric shock to the heart to terminate episodes of ventricular tachycardia and ventricular fibrillation. This is necessary in a patient with significant ventricular symptoms. such as tachycardia resulting in syncope. A patient with myocardial infarction that resolved with no permanent cardiac damage would not be a candidate. A patient recovering well from coronary bypass would not need the device. Atrial tachycardia is less serious and is treated conservatively with medication and cardioversion as a last resort.

    A nurse in the emergency department is observing a 4-year-old child for signs of increased intracranial pressure after a fall from a bicycle. resulting in head trauma. Which of the following signs or symptoms would be cause for concern?

    • Bulging anterior fontanel.

    • Repeated vomiting.

    • Signs of sleepiness at 10 PM.

    • Inability to read short words from a distance of 18 inches.

    Correct Answer
    A. Repeated vomiting.
    Explanation
    Increased pressure caused by bleeding or swelling within the skull can damage delicate brain tissue and may become life threatening. Repeated vomiting can be an early sign of pressure as the vomit center within the medulla is stimulated. The anterior fontanel is closed in a 4-year-old child. Evidence of sleepiness at 10 PM is normal for a four-year-old. The average 4-year-old child cannot read yet. so this too is normal.

    A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?

    • The patient is allergic to shellfish.

    • The patient has a pacemaker.

    • The patient suffers from claustrophobia.

    • The patient takes anti-psychotic medication.

    Correct Answer
    A. The patient has a pacemaker.
    Explanation
    The implanted pacemaker will interfere with the magnetic fields of the MRI scanner and may be deactivated by them. Shellfish/iodine allergy is not a contraindication because the contrast used in MRI scanning is not iodine-based. Open MRI scanners and anti-anxiety medications are available for patients with claustrophobia. Psychiatric medication is not a contraindication to MRI scanning.

    A patient with leukemia is receiving chemotherapy that is known to depress bone marrow. A CBC (complete blood count) reveals a platelet count of 25.000/microliter. Which of the following actions related specifically to the platelet count should be included in the nursing care plan?

    • Monitor for fever every 4 hours.

    • Require visitors to wear respiratory masks and protective clothing.

    • Consider transfusion of packed red blood cells.

    • Check for signs of bleeding. including examination of urine and stool for blood.

    Correct Answer
    A. Check for signs of bleeding. including examination of urine and stool for blood.
    Explanation
    A platelet count of 25.000/microliter is severely thrombocytopenic and should prompt the initiation of bleeding precautions. including monitoring urine and stool for evidence of bleeding. Monitoring for fever and requiring protective clothing are indicated to prevent infection if white blood cells are decreased. Transfusion of red cells is indicated for severe anemia.

Divided into 3 doses per day. the child should receive 50 mg 3 times a day rather than 25 mg 3 times a day. Dosage should not be titrated based on symptoms without consulting a physician.

In young infants. it is common for the testes to retract into the inguinal canal when the environment is cold or the cremasteric reflex is stimulated. Exam should be done in a warm room with warm hands. It is most likely that both testes are present and will descend by a year. If not. a full assessment will determine the appropriate treatment.
