A patient with CHF has the following input/output history
Yesterday Today
IN 1900 mL 2100 mL
OUT 1000 mL 1100 mL
Which of the following clinical findings is most likely to be observed?
A. bronchial wheezing
B. friction rub
C. decreased egophony
D. moist crepitant rales ✔✔The correct answer is : D
Explanation : This CHF patient is obviously retaining fluid because he is receiving more fluid in
that he is putting out. The clinical finding most associated with fluid retention is moist crepitant
rales. Fine rales are associated with atelectasis but moist rales is associated with fluid retention,
especially congestive heart failure (CHF).
,An infant born 24 hours prior is experiencing frequent periods of apnea lasting more than 60
seconds. Which of the following medications would be helpful in stimulating the infant's
respiratory drive?
A. Aminophylline
B. Fluticasone
C. hormone
D. Exosurf ✔✔The correct answer is : A
Explanation : An infant who experiences apnea periods greater than 60 seconds may need
respiratory stimulation. This may be accomplished by administering the medication
Aminophylline. Aminophlylline is only intended for ventilatory stimulation in infants. The same
medication is used for long-term bronchodilation in adults.
A respiratory therapist is having difficulty advancing a suction catheter down a fenestrated
tracheostomy tube while the inner cannula is removed. The cannula appears to meet resistance
within a few inches from insertion. The therapist should
A. remove the tracheostomy tube
,B. twist the catheter while attempting to advance
C. inflate the cuff
D. obtain a smaller suction catheter ✔✔The correct answer is : B
Explanation : When suctioning somebody with a fenestrated tracheostomy tube, it must be
remembered that the suction catheters can sometimes get stuck on the fenestration hole inside the
tube. The best remedy for this is to twist the suction catheter until the end is clear of the hole.
The following flow volume loop (loop is tall and skinny) is obtained from a 62-year-old factory
worker. Which of the following could represent the patient's diagnosis?
A. pulmonary fibrosis
B. emphysema
C. cystic fibrosis
D. chronic bronchitis ✔✔The correct answer is : A
Explanation : The flow volume loop is tall and skinny, indicating normal flows but abnormal
volumes. This is consistent with a restrictive lung defect. The best answer is the disease that is
restrictive in nature. In this case, only pulmonary fibrosis qualifies.
, Which of the following should be monitored for a ventilator-dependent newborn with IRDS?
A. gas distribution (SBN2) in the lungs
B. urine specific gravity
C. pH
D. fluid input and output ✔✔The correct answer is : D
Explanation : All choices are indicated while monitoring a critically ill neonate receiving
mechanical ventilation. I & O fluid monitoring is essential. Managing acid-base balance and the
artificial airway are also essential.
Which of the following is an important element of instruction to a home care patient who will be
receiving continuous oxygen therapy at 2 L/min by nasal cannula?
A. check oxygen concentrator flow rate once a week
B. run a flow calibration check once monthly
C. do not change flow rate without a physician order
D. increase flow rate during exercise ✔✔The correct answer is : C
