The nurse determines that a client understands the purpose of a phytonadione injection for her newborn when she is heard making which statement to the baby's father?
- A. The baby's liver cannot produce that vitamin.
- B. Most newborns need a supplement of this vitamin.
- C. All newborns lack intestinal bacteria to produce this vitamin.
- D. It's unusual but our baby lack's the vitamin that helps the blood to clot.
Correct Answer: C
Rationale: The absence of normal flora needed to synthesize vitamin K (phytonadione) in the normal newborn gut results in low levels of vitamin K and creates a transient blood coagulation deficiency between the second and fifth day of life. An injection is administered prophylactically on the day of birth to combat the deficiency.

After assisting with a vaginal delivery, what should the nurse do to prevent heat loss via conduction in the newborn?
- A. Wrap the newborn in a blanket.
- B. Close the doors to the delivery room.
- C. Dry the newborn with a warm blanket.
- D. Place the newborn on a warm crib pad.
Correct Answer: D
Rationale: Hypothermia caused by conduction occurs when the newborn is on a cold surface, such as a cold pad or mattress. Warming the crib pad will assist in preventing hypothermia by conduction. Radiation occurs when heat from the newborn radiates to a colder surface. Convection occurs as air moves across the newborn's skin from an open door and heat is transferred to the air. Evaporation of moisture from a wet body dissipates heat along with the moisture. Keeping the newborn dry by drying the wet newborn at birth will prevent hypothermia via evaporation.
The nurse assists the primary health care provider with the removal of a chest tube. During the procedure, the nurse instructs the client to perform which action?
- A. Inhale deeply.
- B. Breathe normally.
- C. Breathe out forcefully.
- D. Take a deep breath and hold it.
Correct Answer: D
Rationale: The client is instructed to take a deep breath and hold it for chest tube removal. This maneuver will increase intrathoracic pressure, thereby lessening the potential for air to enter the pleural space. Therefore, options 1, 2, and 3 are incorrect.
A client has been diagnosed with left tension pneumothorax. Which finding observed by the nurse indicates that the pneumothorax is rapidly worsening? Select all that apply.
- A. Hypertension
- B. Flat neck veins
- C. Increased cyanosis
- D. Tracheal deviation to the right
- E. Diminished breath sounds on the left
- F. Observable asymmetry of the thorax
Correct Answer: C,D,E,F
Rationale: A tension pneumothorax is characterized by distended neck veins, displaced point of maximal impulse (PMI), tracheal deviation to the unaffected side, asymmetry of the thorax, decreased to absent breath sounds on the affected side, worsening cyanosis, and worsening dyspnea. The increased intrathoracic pressure causes the blood pressure to fall, not rise.
A client is scheduled for hydrotherapy for a burn dressing change. Which action should the nurse take to ensure that the client is comfortable during the procedure?
- A. Ensure that the client is appropriately dressed.
- B. Administer an opioid analgesic 30 to 60 minutes before therapy.
- C. Schedule the therapy at a time when the client generally takes a nap.
- D. Assign an unlicensed assistive personnel (UAP) to stay with the client during the procedure.
Correct Answer: B
Rationale: The client should receive pain medication approximately 30 to 60 minutes before a burn dressing change. This will help the client tolerate an otherwise painful procedure. None of the remaining options addresses the issue of pain effectively.
A client with a spinal cord injury is at risk of developing footdrop. What intervention should the nurse use as a preventive measure?
- A. Mole skin-lined heel protectors
- B. Regular use of posterior splints
- C. Application of pneumatic boots
- D. Avoiding dorsal flexion of the foot
Correct Answer: B
Rationale: The effective means of preventing footdrop (plantar flexion) is the use of posterior splints or high-top sneakers. Dorsal flexing of the foot would help to counteract the effects of footdrop. Heel protectors protect the skin but do not prevent footdrop. Pneumatic boots prevent deep vein thrombosis but not footdrop.
