Nokea
The acute medical nurse is preparing to wean a patient from the ventilator. Which assessment parameter is most important for the nurse to assess?
- A. Fluid intake for the last 24 hours
- B. Baseline arterial blood gas (ABG) levels
- C. Prior outcomes of weaning
- D. Electrocardiogram (ECG) results
Correct Answer: B
Rationale: Before weaning a patient from mechanical ventilation, it is most important to have baseline ABG levels. During the weaning process, ABG levels will be checked to assess how the patient is tolerating the procedure. Other assessment parameters are relevant, but less critical. Measuring fluid volume intake and output is always important when a patient is being mechanically ventilated. Prior attempts at weaning and ECG results are documented on the patients record, and the nurse can refer to them before the weaning process begins.

The nurse is caring for a patient who is scheduled to have a thoracotomy. When planning preoperative teaching, what information should the nurse communicate to the patient?
- A. How to milk the chest tubing
- B. How to splint the incision when coughing
- C. How to take prophylactic antibiotics correctly
- D. How to manage the need for fluid restriction
Correct Answer: B
Rationale: Prior to thoracotomy, the nurse educates the patient about how to splint the incision with the hands, a pillow, or a folded towel. The patient is not taught how to milk the chest tubing because this is performed by the nurse. Prophylactic antibiotics are not normally used and fluid restriction is not indicated following thoracotomy.
The nurse is caring for a client with an endotracheal tube who is on a ventilator. When assessing the client, the nurse knows to maintain what cuff pressure to maintain appropriate pressure on the tracheal wall?
- A. Between 10 and 15 mm Hg
- B. Between 15 and 20 mm Hg
- C. Between 20 and 25 mm Hg
- D. Between 25 and 30 mm Hg
Correct Answer: B
Rationale: Complications can occur from pressure exerted by the cuff on the tracheal wall. Cuff pressures should be maintained between 15 and 20 mm Hg.
The nurse is caring for a patient who is experiencing mild shortness of breath during the immediate postoperative period, with oxygen saturation readings between 89% and 91%. What method of oxygen delivery is most appropriate for the patients needs?
- A. Non-rebreathing mask
- B. Nasal cannula
- C. Simple mask
- D. Partial-rebreathing mask
Correct Answer: B
Rationale: A nasal cannula is used when the patient requires a low to medium concentration of oxygen for which precise accuracy is not essential. The Venturi mask is used primarily for patients with COPD because it can accurately provide an appropriate level of supplemental oxygen, thus avoiding the risk of suppressing the hypoxic drive. The patients respiratory status does not require a partial- or non-rebreathing mask.
The nurse is preparing to suction a patient with an endotracheal tube. What should be the nurses first step in the suctioning process?
- A. Explain the suctioning procedure to the patient and reposition the patient
- B. Turn on suction source at a pressure not exceeding 120 mm Hg
- C. Assess the patients lung sounds and SAO2 via pulse oximeter
- D. Perform hand hygiene and don nonsterile gloves, goggles, gown, and mask
Correct Answer: C
Rationale: Assessment data indicate the need for suctioning and allow the nurse to monitor the effect of suction on the patients level of oxygenation. Explaining the procedure would be the second step; performing hand hygiene is the third step, and turning on the suction source is the fourth step.
The medical nurse is creating the care plan of an adult patient requiring mechanical ventilation. What nursing action is most appropriate?
- A. Keep the patient in a low Fowlers position
- B. Perform tracheostomy care at least once per day
- C. Maintain continuous bedrest
- D. Monitor cuff pressure every 8 hours
Correct Answer: D
Rationale: The cuff pressure should be monitored every 8 hours. It is important to perform tracheostomy care at least every 8 hours because of the risk of infection. The patient should be encouraged to ambulate, if possible, and a low Fowlers position is not indicated.
