A patient has a temporary transvenous VVI pacemaker with a set rate of
72 beats/minute and an mA output of 5. The monitor shows 1:1 pacing at
the set rate. The physician asks the nurse to determine the capture
threshold. Which of the following should the nurse do?
(A) Slowly increase the sensitivity until the heart rate increases.
(B) Slowly decrease the sensitivity until the capture is lost.
(C) Slowly increase the mA output until the native beats are seen.
(D) Slowly decrease the mA output until the capture is lost. - ANSWER-
(D) Slowly decrease the mA output until the capture is lost.
A patient is alert and is receiving mechanical ventilation with the
following settings: assist-control mode at 10 breaths/minute, FIO2 0.40,
and PEEP 5 cm H2O pressure. Vital signs include a BP of 104/58, a
heart rate of 90 beats/minute, and a respiratory rate of 18 breaths/minute,
with norepinephrine at 7 mcg/min for the past 4 hours. The patient has
tolerated repositioning in bed and a head of bed elevation up to 90°.
Which of the following would be an appropriate next step in terms of
mobility for this patient?
(A) Allow the patient to sit on the edge of the bed, with assistance.
(B) Reduce the head of bed elevation to 45°.

A 70 kg patient with ARDS is mechanically ventilated with the
following settings: FiO2 70%, tidal volume 450 mL, assist-control mode
10 breaths/minute, and PEEP 20 cm H2O pressure. On these settings, the
patient's PaO2 is 76 mmHg and the PaCO2 is 58 mmHg. The patient's
core temperature is 37°C, his heart rate is 116 beats/minute, and his BP
is 78/58. Which of the following interventions should the nurse now
anticipate?

procurement agency.
