A. Tachycardia and hypertension D. Laryngeal stridor and hoarseness E. Positive Trousseau's sign Tachycardia and hypertension are unexpected findings that can indicate the occurrence of thyroid storm following removal of the thyroid gland, especially if the client was in a hyperthyroid state prior to the surgery. thyrotoxicity (thyroid storm) is a life-threatening condition with a sudden onset that includes tachycardia, a fever, sweating, restlessness, and tremors. Congestive heart failure and pulmonary edema can develop rapidly and lead to death. Laryngeal stridor and hoarseness are unexpected findings and can indicate swelling in the area of the surgery or damage to the laryngeal nerve. This should be reported to the provider before respiratory distress develops. A positive Trousseau's sign is an indication of hypocalcemia, which is a complication of thyroid removal. This occurs when the parathyroid glands are also removed and regulation of serum calcium is impaired.

Which of the following statements should the nurse include when teaching the child's parent? A. "The PICC line will last for several weeks with proper care." B. "The public health nurse will rotate the insertion site every 3 days." C. " You will need to ensure the arm board is in place at all times." D. " Your child will go to the operating room to have a line placed."

A. "The PICC line will last for several weeks with proper care." A PICC line is the preferred venous access device for short- to moderate- term IV therapy. It can remain in place for long periods with proper care.

A nursing is assessing a client who has a fluid volume overload from a cardiovascular disorder. Which of the following manifestations should the nurse expect? (Select all that apply) A. Jugular vein distension B. Moist crackles C. Postural hypotension D. Increased heart rate E. Fever

A. Jugular vein distension B. Moist crackles D. Increased heart rate The increased venous pressure due to excessive circulating blood volume results in neck vein distension. Moist crackles are an indicator of pulmonary edea that can quickly lead to death. Fluid volume excess (hypervolemia) is an expansion of fluid volume in the extracellular compartment, which results in an increased heart rate and bounding pulses.

A nurse is caring for an infant who has tetralogy of Fallot and is experiencing a hypercyanotic episode. Which of the following actions should the nurse take? A. Place the infant in a Knee-chest position B. Initiate a fluid restriction C. Provide oxygen by nasal cannula D. Administer acetaminophen

A. Place the infant in a Knee-chest position - The nurse should place the infant in a knee-chest position durning a hypercyanotic episode. This position reduces the return of desaturated blood from the legs through the venous system and promotes the diversion of blood into the pulmonary artery.

A nurse in a provider's office receives a phone call from the guardian of an infant who just vomited after the administration of digoxin. Which of the following actions should the nurse take first? A. Tell the guardian that a repeat dose of the medication should not be given. B. Verify the prescribed medication regimen C. Determine if the infant has been exposed to others who are ill D. Ask the guardian the infant's urinary output

A. Tell the guardian that a repeat dose of the medication should not be given. -The greatest risk to this infant is an injury from digoxin toxicity. Therefore, the priority action for the nurse to take is to instruct the guardian not to administer another dose of the medication. The nurse should follow-up with the guardian frequently to determine if the child has further episodes of vomiting. If so, the nurse should notify the provider immediately because vomiting is a possible indication of digoxin toxicity.

A nurse is caring for a group of infants with congenital heart defects. For which of the following defects should the nurse expect to observe cyanosis? A. Transposition of the great arteries B. Ventricular septal defect (VSD) C. Coarctation of the aorta D. Patent ductus arteriosus (PDA)

A. Transposition of the great arteries - An infant who has transposition of the great arteries will have severe cyanosis because reversal of the anatomical position of the aorta and pulmonary artery allows venous blood to enter the systemic circulation without oxygenation.

A. Give extra feedings B. Provide extra calories for infants C. Do not feed the baby with medication D. The infant can take indomethacin with juice

B. Provide extra calories for infants

An infant that is experiencing a hypercyanotic episode an needs oxygen. What device should the nurse expect to put on the infant to deliver the oxygen?

Face mask -The nurse should apply the face mask to the infant to deliver 100% oxygen to treat the hyprecyanotic episode.

A nurse is caring for a child who has tetralogy of fallot. Which of the following laboratory values should the nurse expect to find? A. Platelet count of 20,000/mm^3 B. WBC 4,000/mm^3 C. Thyroid stimulating hormone 7.0 microunits/mL D. RBC 6.8 million/uL

D. RBC 6.8 million/uL -A child who has tetralogy of Fallot experiences cyanosis; therefore, the body responds by increasing RBC production (polycythemia) in an attempt to supply oxygen to all body parts.
