The nurse assessing the apical heart rates of several different newborn infants notes that which heart rate is normal for this newborn population?
- A. 90 beats per minute
- B. 140 beats per minute
- C. 180 beats per minute
- D. 190 beats per minute
Correct Answer: B
Rationale: The normal heart rate in a newborn infant is approximately 100 to 160 beats per minute. Options 1, 3, and 4 are incorrect. Option 1 indicates bradycardia, and options 3 and 4 indicate tachycardia (greater than 100 beats per minute).

A child hospitalized with a diagnosis of lead poisoning is prescribed chelation therapy. The nurse caring for the child should prepare to administer which medication?
- A. Ipecac syrup
- B. Activated charcoal
- C. Sodium bicarbonate
- D. Calcium disodium edetate (EDTA)
Correct Answer: D
Rationale: EDTA is a chelating agent that is used to treat lead poisoning. Ipecac syrup may be prescribed by the primary health care provider for use in the hospital setting but would not be used to treat lead poisoning. Activated charcoal is used to decrease absorption in certain poisoning situations. Sodium bicarbonate may be used in salicylate poisoning.
A client prescribed warfarin sodium has been instructed to limit the intake of foods high in vitamin K. The nurse determines that the client understands the instructions if the client indicates that which food items need to be avoided? Select all that apply.
- A. Tea
- B. Turnips
- C. Oranges
- D. Cabbage
- E. Broccoli
- F. Strawberries
Correct Answer: A,B,D,E
Rationale: Warfarin sodium is an anticoagulant that interferes with the hepatic synthesis of vitamin K-dependent clotting factors. The client is instructed to limit the intake of foods high in vitamin K while taking this medication. These foods include coffee or tea (caffeine), turnips, cabbage, broccoli, greens, fish, and liver.
After undergoing a thyroidectomy, a client is monitored for signs of damage to the parathyroid glands postoperatively. The nurse would determine which finding suggests damage to the parathyroid glands?
- A. Fever
- B. Neck pain
- C. Hoarseness
- D. Tingling around the mouth
Correct Answer: D
Rationale: The parathyroid glands can be damaged or their blood supply impaired during thyroid surgery. Hypocalcemia and tetany result when parathyroid hormone (PTH) levels decrease. The nurse monitors for complaints of tingling around the mouth or of the toes or fingers and muscular twitching because these are signs of calcium deficiency. Additional later signs of hypocalcemia are positive Chvostek's and Trousseau's signs. Fever may be expected in the immediate postoperative period but is not an indication of damage to the parathyroid glands. However, if a fever persists the primary health care provider is notified. Neck pain and hoarseness are expected findings postoperatively.
Which observation by the nurse indicates a need to suction a client with an endotracheal (ET) tube attached to a mechanical ventilator? Select all that apply.
- A. Audible crackles
- B. Client notably restless
- C. Visible mucus bubbling in the ET tube
- D. Apical pulse rate of 72 beats per minute
- E. Low peak inspiratory pressure on the ventilator
- F. High alarm pressures identified by the ventilator
Correct Answer: A,B,C,F
Rationale: Indications for suctioning include visible mucus bubbling in the ET tube, wet respirations, restlessness, rhonchi or crackles on auscultation of the lungs, increased pulse and respiratory rates, and increased peak inspiratory pressures on the ventilator and high-pressure alarms on the ventilator. A low peak inspiratory pressure indicates a leak in the mechanical ventilation system.
The nurse has completed tracheostomy care for a client whose tracheostomy tube has a nondisposable inner cannula. Which intervention will the nurse implement immediately before reinserting the inner cannula?
- A. Rinsing it in sterile water
- B. Suctioning the client's airway
- C. Tapping it gently against a sterile basin
- D. Drying it with the provided pipe cleaners
Correct Answer: D
Rationale: After washing and rinsing the inner cannula, the nurse taps it dry to remove large water droplets and then uses pipe cleaners specifically for use with a tracheostomy to dry it; then the nurse inserts the cannula into the tracheostomy and turns it clockwise to lock it into place. The nurse should avoid shaking or tapping the inner cannula to prevent contamination. A wet cannula should not be inserted into a tracheostomy because water is a lung irritant.
