The nurse provides a class to new mothers on newborn care. When teaching cord care, the nurse should instruct mothers to take which action?
- A. If antibiotic ointment has been applied to the cord, it is not necessary to do anything else to it.
- B. All that is necessary is to wash the cord with antibacterial soap and allow it to air-dry once a day.
- C. Apply alcohol thoroughly to the cord, being careful not to move the cord because it will cause pain to the newborn infant.
- D. Apply the prescribed cleansing agent to the cord, ensuring that all areas around the cord are cleaned two to three times a day.
Correct Answer: D
Rationale: The cord and base should be cleansed with alcohol (or another substance as prescribed) thoroughly, two to three times per day. The steps are (1) lift the cord; (2) wipe around the cord, starting at the top; (3) clean the base of the cord; and (4) fold the diaper below the umbilical cord to allow the cord to air-dry and prevent contamination from urine. Antibiotic ointment is not normally prescribed. Continuation of cord care is necessary until the cord falls off within 7 to 14 days. Water and soap are not necessary; in fact, the cord should be kept from getting wet. The infant does not feel pain in this area.

A child is admitted to the hospital with a diagnosis of rheumatic fever. The nurse reviews the blood laboratory findings, knowing that which finding will confirm the likelihood of this disorder?
- A. Increased leukocyte count
- B. Decreased hemoglobin count
- C. Increased antistreptolysin-O (ASO titer)
- D. Decreased erythrocyte sedimentation rate
Correct Answer: C
Rationale: Children suspected of having rheumatic fever are tested for streptococcal antibodies. The most reliable and best standardized test to confirm the diagnosis is the ASO titer. An elevated level indicates the presence of rheumatic fever. The remaining options are unrelated to diagnosing rheumatic fever. Additionally, an increased leukocyte count indicates the presence of infection but is not specific in confirming a particular diagnosis.
A client has had a nasointestinal (NI) tube in place for 24 hours. Which assessment finding indicates that the tube is properly located in the intestine?
- A. Bowel sounds are absent.
- B. The client denies being nauseous.
- C. Aspirate from the tube has a pH of 7.
- D. The abdominal x-ray indicates that the end of the tube is above the pylorus.
Correct Answer: C
Rationale: The nasogastric (NG) or NI tube is used to decompress the intestine and correct a bowel obstruction. Nausea should subside as decompression is accomplished. The pH of the gastric fluid is acidic, and the pH of the intestinal fluid is alkaline (7 or higher). Although bowel sounds will be abnormal in the presence of obstruction, the presence or absence of bowel sounds is not associated with the location of the tube. The end of the tube should be located in the intestine (below the pylorus). Location of the tube can also be determined by radiographs.
The nurse evaluates a client after treatment for carbon monoxide poisoning following a burn injury. The nurse should document that the treatment was effective if which finding was present? Select all that apply.
- A. The client is sleeping soundly.
- B. The client is awake and talking.
- C. Respiratory rate is 26 breaths/minute.
- D. The client's heart rate is 84 beats/minute.
- E. Carboxyhemoglobin levels are less than 5%.
- F. The heart monitor shows normal sinus rhythm.
Correct Answer: D,E,F
Rationale: Normal carboxyhemoglobin levels are less than 5% for a nonsmoking adult. Clients can be awake and talking with abnormally high levels. The symptoms of carbon monoxide poisoning are tachycardia, tachypnea, and central nervous system depression.
After a client diagnosed with pleural effusion had a thoracentesis, a sample of fluid was sent to the laboratory. Analysis of the fluid reveals a high red blood cell count. Based on this test result, what was the cause of this client's pleural effusion?
- A. Trauma
- B. Infection
- C. Liver failure
- D. Heart failure
Correct Answer: A
Rationale: Pleural fluid from an effusion that has a high red blood cell count may result from trauma and may be treated with placement of a chest tube for drainage. Other causes of pleural effusion include infection, heart failure, liver or renal failure, malignancy, or inflammatory processes. Infection would be accompanied by white blood cells. The fluid portion of the serum would accumulate with liver failure and heart failure.
The nurse is caring for a client who has experienced a thoracic spinal cord injury. In the event that spinal shock occurs, which intravenous (IV) fluid should the nurse anticipate being prescribed?
- A. Dextran
- B. 0.9% normal saline
- C. 5% dextrose in water
- D. 5% dextrose in 0.9% normal saline
Correct Answer: B
Rationale: Normal saline 0.9% is an isotonic solution that primarily remains in the intravascular space, increasing intravascular volume. This IV fluid would increase the client's blood pressure. Dextran is rarely used in spinal shock because isotonic fluid administration is usually sufficient. Additionally, Dextran has potential adverse effects. Dextrose 5% in water is a hypotonic solution that pulls fluid out of the intravascular space and is not indicated for shock. Dextrose 5% in normal saline 0.9% is hypertonic and may be indicated for shock resulting from hemorrhage or burns.
